2017-02-16regulator: core: Resolve supplies before disabling unused regulatorsJavier Martinez Canillas1-0/+10
After commit 66d228a2bf03 ("regulator: core: Don't use regulators as supplies until the parent is bound"), input supplies aren't resolved if the input supplies parent device has not been bound. This prevent regulators to hold an invalid reference if its supply parent device driver probe is deferred. But this causes issues on some boards where a PMIC's regulator use as input supply a regulator from another PMIC whose driver is registered after the driver for the former. In this case the regulators for the first PMIC will fail to resolve input supplies on regulators registration (since the other PMIC wasn't probed yet). And when the core attempts to resolve again latter when the other PMIC registers its own regulators, it will fail again since the parent device isn't bound yet. This will cause some parent supplies to never be resolved and wrongly be disabled on boot due taking them as unused. To solve this problem, also attempt to resolve the pending regulators input supplies before disabling the unused regulators.

2017-02-16Staging: comedi: drivers: comedi_test: Add auto-configuration capabilityCheah Kok Cheong1-12/+123
Currently this module needs to be manually configured by COMEDI userspace tool before the test waveform can be read by a COMEDI compatible application. This patch adds auto-configuration capability and makes it the default loading option. This is achieved by creating a device during init to stand in for a real hardware device. This allows comedi_auto_config() to perform auto-configuration. With this patch, the test waveform can be read by a COMEDI compatible application without needing manual configuration. Previous behaviour is still selectable via module loading parameter. Module loading without passing any parameter will default to auto-configuration with the same default waveform amplitude and period values. For auto-configuration, different amplitude and period values can be set via module loading parameters. Tested on Xubuntu 16.04 using Xoscope ver: 2.0 which is available in the Ubuntu repository. Xoscope is a COMEDI compatible digital oscilloscope application. For manual configuration, only module loading/unloading is tested. Here are the truncated dmesg output. [sudo modprobe comedi_test] comedi_test: 1000000 microvolt, 100000 microsecond waveform attached driver 'comedi_test' has successfully auto-configured 'comedi_test'. [sudo modprobe comedi_test amplitude=2500000 period=150000] comedi_test: 2500000 microvolt, 150000 microsecond waveform attached driver 'comedi_test' has successfully auto-configured 'comedi_test'. [sudo modprobe comedi_test noauto=1] comedi_test: module is from the staging directory, the quality is unknown, you have been warned. For those without an actual hardware, the comedi_test module is as close as one can get to test the COMEDI system. Having both auto and manual configuration capability will broaden the test function of this module. Hopefully this will make it easier for people to check out the COMEDI system and contribute to its development.

The metadata_space_map_root passed to sm_ll_open_metadata() may or may not be arch aligned, use memcpy to ensure it is. This is not a fast path so the extra memcpy doesn't hurt us. Long-term it'd be better to use the kernel's alignment infrastructure to remove the memcpy()s that are littered across persistent-data (btree, array, space-maps, etc).

Flags (PIPE_BUF_FLAG_PACKET, PIPE_BUF_FLAG_GIFT) could remain on the unused part of the pipe ring buffer. Previously splice_to_pipe() left the flags value alone, which could result in incorrect behavior. Uninitialized flags appears to have been there from the introduction of the splice syscall.

The BCM2E96 ID is used by the ECS EF20 laptop, and BCM2E95 is present in the Weibu F3C. Both are now logged as: hci0: BCM: chip id 82 hci0: BCM43341B0 (002.001.014) build 0000 hci0: BCM (002.001.014) build 0158 The ECS vendor kernel predates the host-wakeup support in hci_bcm but it explicitly has a comment saying that the GPIO assignment needs to be reordered for BCM2E96: 1. (not used in vendor driver) 2. Device wakeup 3. Shutdown For both devices in question, the DSDT has these GPIOs listed in order of GpioInt, GpioIo, GpioIo. And if we use the first one listed (GpioInt) as the host wakeup, that interrupt handler fires while doing bluetooth I/O. I am assuming the convention of GPIO ordering has been changed for these new device IDs, so lets use the new ordering on such devices.

2017-02-16Bluetooth: btusb: Configure Marvell to use one of the pins for oob wakeupRajat Jain3-8/+92
The Marvell devices may have many gpio pins, and hence for wakeup on these out-of-band pins, the chip needs to be told which pin is to be used for wakeup, using an hci command. Thus, we read the pin number etc from the device tree node and send a command to the chip.

2017-02-16Bluetooth: btusb: Add out-of-band wakeup supportRajat Jain2-0/+125
Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that can be connected to a gpio on the CPU side, and can be used to wakeup the host out-of-band. This can be useful in situations where the in-band wakeup is not possible or not preferable (e.g. the in-band wakeup may require the USB host controller to remain active, and hence consuming more system power during system sleep). The oob gpio interrupt to be used for wakeup on the CPU side, is read from the device tree node, (using standard interrupt descriptors). A devcie tree binding document is also added for the driver. The compatible string is in compliance with Documentation/devicetree/bindings/usb/usb-device.txt Signed-off-by: Rajat Jain <[email protected]> Reviewed-by: Brian Norris <[email protected]> Acked-by: Rob Herring <[email protected]> Signed-off-by: Marcel Holtmann <[email protected]>

Currently, the IPID and Syndrome are printed on the same line as the Address. There are cases when we can have a valid Syndrome but not a valid Address. For example, the MCA_SYND register can be used to hold more detailed error info that the hardware folks can use. It's not just DRAM ECC syndromes. There are some error types that aren't related to memory that may have valid syndromes, like some errors related to links in the Data Fabric, etc. In these cases, the IPID and Syndrome are not printed at the same log level as the rest of the stanza, so users won't see them on the console.

2017-02-16genirq: Clarify logic calculating bogus irqreturn_t valuesJeremy Kerr1-1/+3
Although irqreturn_t is an enum, we treat it (and its enumeration constants) as a bitmask. However, bad_action_ret() uses a less-than operator to determine whether an irqreturn_t falls within allowable bit values, which means we need to know the signededness of an enum type to read the logic, which is implementation-dependent. This change explicitly uses an unsigned type for the comparison. We do this instead of changing to a bitwise test, as the latter compiles to increased instructions in this hot path. It looks like we get the correct behaviour currently (bad_action_ret(-1) returns 1), so this is purely a readability fix.
