Since commit 3c47d19ff4dc ("drivers: base: add coredump driver ops")
it is possible to initiate a device coredump from user-space. This
patch adds support for it in btmrvl_sdio adding the .coredump()
driver callback. This makes dump through debugfs obsolete so removing
it.

In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") we tried to address the non-working Atheros BT devices
by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made
such devices working while it turned out to break other existing chips
with the very same USB ID, hence it was reverted afterwards.
This is another attempt to tackle the issue. The essential point to
use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM-
patching. And the previous attempt failed because btusb_setup_qca()
returns -ENODEV if the ROM version doesn't match with the expected
ones. For some devices that have already the "correct" ROM versions,
we may just skip the setup procedure and continue the rest.
So, the first fix we'll need is to add a check of the ROM version in
the function to skip the setup if the ROM version looks already sane,
so that it can be applied for all ath devices.
However, the world is a bit more complex than that simple solution.
Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's
0x0001 at the beginning of probing, so the device probe always aborts
here.
In this patch, we add another check of ROM version again, and if the
device needs patching, the probe continues. For that, a slight
refactoring of btusb_qca_send_vendor_req() was required so that the
probe function can pass usb_device pointer directly before allocating
hci_dev stuff.

This patch adds rampatch download compatibility for ROME >= 3.2.
Starting with ROME 3.2, the 'download mode' field of the rampatch
header indicates if the controller acknowledges (or not) the received
rampatch segments. If not, we need to send all the segments without
expecting any event from the controller (except for the last segment).
Goal is (I assume) to speed-up rampatch download.
This fixes BT on Dragonboard-600c P2 which includes the following BT
controller:

btbcm_setup_patchram() was using the upper nibble of the revision code to
determine if we are dealing with an uart or USB connected bcm-bt device,
but just as btbcm_initialize() has started accepting 1 and 2 as uart
connected devices, I've now encountered an USB connected device (0a5c:216c)
which has 0 in the upper nibble. So it seems that the upper nibble is not
really a reliable indicator of the bus type.
Instead check hdev->bus which does give us a reliable indication. This
fixes the patchram code trying to load the patchram by the fallback BCM.hcd
filename, now it correctly requests BCM43142A0-0a5c-216c.hcd.

Interrupts specified through an "Interrupt" ACPI resource (versus through
a "GpioInt" resource) are now always assumed to be active low.
When this change was originally made the Thinkpad 8 quirk was kept around
because it was uncertain if the Thinkpad 8 uses an "Interrupt" or a
"GpioInt" resource.
Bug https://bugzilla.kernel.org/show_bug.cgi?id=196701 has a DSDT for the
Thinkpad 8 attached and it uses an "Interrupt" resource, so the quirk is
not necessary and the quirk, as well as the irq-active-low quirk handling
code can be removed.

The Meegopad T08 hdmi-stick (think Intel computestick) has a brcm43430
wifi/bt combo chip. The BCM2E90 ACPI device describing the BT part does
contain a valid ActiveLow GpioInt entry, but the GPIO it points to never
goes low, so either the IRQ pin is not connected, or the ACPI resource-
table points to the wrong GPIO.
Eitherway things will not work if we try to use the specified IRQ, this
commits adds a DMI based broken-irq blacklist and disables use of the IRQ
and thus also runtime-pm for devices on this list.
This blacklist starts with the the Meegopad T08, fixing bluetooth not
working on this hdmi-stick. Since this is not a battery powered device
the loss of runtime-pm is not really an issue.

Jeremy Cline correctly points out in rhbz#1514836 that a device where the
QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship
with a different wifi/bt chipset in some configurations.
If that is the case then we are needlessly penalizing those other chipsets
with a reset-resume quirk, typically causing 0.4W extra power use because
this disables runtime-pm.
This commit moves the DMI table check to a btusb_check_needs_reset_resume()
helper (so that we can easily also call it for other chipsets) and calls
this new helper only for QCA_ROME chipsets for now.

Now that we need just an ACPI HID in the table, and the driver auto-
configures itself otherwise, we can easily add a bunch of known ACPI HIDs.
This avoids having to add these 1 by 1 as devices with one are encountered
by users.
This commit may seem as if it simply adds all IDs between BCM2E00-BCM2EAC,
but that is not true, all these IDs were found in actual .inf files and
the range is not entirely continuous, the following IDs are not added:
BCM2E6A, BCM2E6C, BCM2E8F and BCM2E91 because I did not see these in any
.inf files. As for the large amount of IDs this seems to be caused by
Broadcom using a separate ID for every bluetooth module using their
chips. E.g. BCM2EA6 seems to be specifically for the Raspberry Pi 3.

Since I've been doing a lot of work on Linux Bay Trail / Cherry Trail
support, I've gathered a collection of ACPI DSDTs from about 50 such
machines.
Looking at these DSTDs many have an ACPI device entry describing a bcm
bluetooth device (often disabled in the DSDT), quite a few of these ACPI
device entries have a resource-table where the order does not match with
the order currently associated with the HID of that entry in the
bcm_acpi_match table.
Looking at the Windows .inf files, there is nothing indicating a specific
order there, so I believe that there is no 1:1 mapping between the ACPI
HID and the order in which the resources are listed.
Therefor this commit replaces the hardcoded mapping based on ACPI HID,
with code which actually checks in which order the resources are listed
and bases the gpio-mapping on that.
This should ensure that we always pick the right mapping and this will
make adding new ACPI HIDs to the driver easier.
This has been tested on the following devices:
-Asus T100CHI BCM2E39 / brcmfmac43241b4-sdio / BCM4324B3-37.4M.hcd
-Asus T100TA BCM2E39 / brcmfmac43241b4-sdio / BCM4324B3-37.4M.hcd
-Asus T200TA BCM2E65 / brcmfmac43340-sdio / BCM43341B0-37.4M.hcd
-Jumper ezPad mini 3 BCM2E74 / brcmfmac43430a0-sdio / BCM4343A0-26M.hcd
-Acer Iconia Tab8 w1-8 BCM2E83 / brcmfmac4330-sdio / BCM4330B1-26M.hcd
-Chuwi Vi8 plus(CWI519) BCM2EAA / brcmfmac43430-sdio / BCM43430A1-26M.hcd
Which together cover all 3 combinations of using an Interrupt resource /
GpioInt resource as first resource / GpioInt resource as last resource.

Older devices with a serdev attached bcm bt hci, use an Interrupt ACPI
resource to describe the IRQ (rather then a GpioInt resource).
These device seem to all claim the IRQ is active-high and seem to all need
a DMI quirk to treat it as active-low. Instead simply always assume that
Interrupt resource specified IRQs are always active-low.
This fixes the bt device not being able to wake the host from runtime-
suspend on the: Asus T100TAM, Asus T200TA, Lenovo Yoga2 and the Toshiba
Encore, without the need to add 4 new DMI quirks for these models.
This also allows us to remove 2 DMI quirks for the Asus T100TA and Asus
T100CHI series. Likely the 2 remaining quirks can also be removed but I
could not find a DSDT of these devices to verify this.

In case the shutdown GPIO is not wired up, it is impossible to reset the
Bluetooth controller to its original state. This include the initial
default baud rate which leads to issues when reloading the module or
when something unexpected happens. To avoid any kind of runtime
deadlocks, stick with the initial default baud rate.

Some GPIO controller drivers request sleepable context and so can't
be accessed from IRQ context. Using gpiod_set/get_value accessors
with such controller leads to a kernel warning since they are
reserved for atomic context (according to the documentation).
Use the postfixed _cansleep version instead, indicating that context
is safe for sleeping if necessary. Note that this is the case here
since we never toggle the gpio neither from IRQ nor from a spinlocked
section.

The linkage between the bluetooth driver and the wireless
driver is not defined properly, leading to build problems
such as:
warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X)
drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':
(.text+0x205): undefined reference to `rsi_bt_ops'
As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next
Kalle Valo says:
====================
wireless-drivers-next patches for 4.17
The biggest changes are the bluetooth related patches to the rsi
driver. It adds a new bluetooth driver which communicates directly
with the wireless driver and the interface is defined in
include/net/rsi_91x.h.
Major changes:
wl1251
* read the MAC address from the NVS file
rtlwifi
* enable mac80211 fast-tx support
mt76
* add capability to select tx/rx antennas
mt7601
* let mac80211 validate rx CCMP Packet Number (PN)
rsi
* bluetooth: add new btrsi driver
* btcoex support with the new btrsi driver
====================

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e61 (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init
stage list to match new order from cleanup patch

The IRQ output of the bcm bt-device is really a level IRQ signal, which
signals a logical high as long as the device's buffer contains data. Since
the draining in the buffer is done in the tty driver, we cannot (easily)
wait in a threaded interrupt handler for the draining, after which the
IRQ should go low again.
So instead we treat the IRQ as an edge interrupt. This opens the window
for a theoretical race where we wakeup, read some data and then autosuspend
*before* the IRQ has gone (logical) low, followed by the device just at
that moment receiving more data, causing the IRQ to stay high and we never
see an edge.
Since we call pm_runtime_mark_last_busy() on every received byte, there
should be plenty time for the IRQ to go (logical) low before we ever
suspend, so this should never happen, but after commit 43fff7683468
("Bluetooth: hci_bcm: Streamline runtime PM code"), which has been reverted
since, this was actually happening causing the device to get stuck in
runtime suspend.
The bcm bt-device actually has a workaround for this, if we set the
pulsed_host_wake flag in the sleep parameters, then the device monitors
if the host is draining the buffer and if not then after a timeout the
device will pulse the IRQ line, causing us to see an edge, fixing the
stuck in suspend condition.
This commit sets the pulsed_host_wake flag to fix the (mostly theoretical)
race caused by us treating the IRQ as an edge IRQ.

This reverts commit 43fff7683468 ("Bluetooth: hci_bcm: Streamline runtime
PM code"). The commit msg for this commit states "No functional change
intended.", but replacing:
pm_runtime_get();
pm_runtime_mark_last_busy();
pm_runtime_put_autosuspend();
with:
pm_request_resume();
Does result in a functional change, pm_request_resume() only calls
pm_runtime_mark_last_busy() if the device was suspended before the call.
This results in the following happening:
1) Device is runtime suspended
2) Device drives host_wake IRQ logically high as it starts receiving data
3) bcm_host_wake() gets called, causes the device to runtime-resume,
current time gets marked as last_busy time
4) After 5 seconds the autosuspend timer expires and the dev autosuspends
as no one has been calling pm_runtime_mark_last_busy(), the device was
resumed during those 5 seconds, so all the pm_request_resume() calls
while receiving data and/or bcm_host_wake() calls were nops
5) If 4) happens while the device has (just received) data in its buffer to
be read by the host the IRQ line is *already* / still logically high
when we autosuspend and since we use an edge triggered IRQ, the IRQ
will never trigger, causing the device to get stuck in suspend
Therefor this commit has to be reverted, so that we avoid the device
getting stuck in suspend.

The Atheros 1525/QCA6174 BT doesn't seem working properly on the
recent kernels, as it tries to load a wrong firmware
ar3k/AthrBT_0x00000200.dfu and it fails.
This seems to have been a problem for some time, and the known
workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.

The issue can be reproduced before commit fd865802c66b ("Bluetooth:

Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA
reset_resume quirking"), added the Lenovo Yoga 920 to the
btusb_needs_reset_resume_table.
Testing has shown that this is a false positive and the problems where
caused by issues with the initial fix: commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume"), which has already been reverted.
So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at
all and this commit removes it from the btusb_needs_reset_resume_table.
Note that after this commit the btusb_needs_reset_resume_table is now
empty. It is kept around on purpose, since this whole series of commits
started for a reason and there are actually broken platforms around,
which need to be added to it.
