sg_init_table zeroes its first argument, so the allocation of that argument
doesn't have to.

This series implements a number of fixes for the FSI-attached SPI
controller driver.
Changes since v1:
- Switch to a new compatible string for the restricted version of the
SPI controller, rather than a new boolean parameter.
Brad Bishop (3):
spi: fsi: Handle 9 to 15 byte transfers lengths
spi: fsi: Fix clock running too fast
spi: fsi: Fix use of the bneq+ sequencer instruction
Eddie James (3):
dt-bindings: fsi: fsi2spi: Add compatible string for restricted
version
spi: fsi: Implement restricted size for certain controllers
spi: fsi: Check mux status before transfers

Currently NXP fspi driver has support of DT only. Adding ACPI
support to the driver so that it can be used by UEFI firmware
booting in ACPI mode. This driver will be probed if any firmware
will expose HID "NXP0009" in DSDT table.

The info message was showing the mapped address of the device. To avoid
security problems, all virtual addresses are converted to __ptrval__, so
the message was useless/ugly:

Some of the FSI-attached SPI controllers cannot use the loop command in
programming the sequencer due to security requirements. Check the
devicetree compatibility that indicates this condition and restrict the
size for these controllers. Also, add more transfers directly in the
sequence up to the length of the sequence register.

All of the switches in N2_count_control in the counter configuration are
required to make the branch if not equal and increment command work.
Set them when using bneq+.
A side effect of this mode requires a dummy write to TDR when both
transmitting and receiving otherwise the controller won't start shifting
receive data.
It is likely not possible to avoid TDR underrun errors in this mode and
they are harmless, so do not check for them.

Use a clock divider tuned to a 200MHz FSI bus frequency (the maximum). Use
of the previous divider at 200MHz results in corrupt data from endpoint
devices. Ideally the clock divider would be calculated from the FSI clock,
but that would require some significant work on the FSI driver. With FSI
frequencies slower than 200MHz, the SPI clock will simply run slower, but
safely.

If we're sending bytes over SPI, we know the FIFO is empty at the
start of the transfer. There's no reason to wait for the interrupt
telling us to start--we can just start right away. Then if we
transmit everything in one swell foop we don't even need to bother
listening for TX interrupts.
In a test of "flashrom -p ec -r /tmp/foo.bin" interrupts were reduced
from ~30560 to ~29730, about a 3% savings.
This patch looks bigger than it is because I moved a few functions
rather than adding a forward declaration. The only actual change to
geni_spi_handle_tx() was to make it return a bool indicating if there
is more to tx.

The arch/arm64/boot/dts/freescale/fsl-ls208xa.dtsi device tree lacks DMA
channels for DSPI, so naturally, the driver fails to probe:
[ 2.945302] fsl-dspi 2100000.spi: rx dma channel not available
[ 2.951134] fsl-dspi 2100000.spi: can't get dma channels
In retrospect, this should have been obvious, because LS2080A, LS2085A
LS2088A and LX2160A don't appear to have an eDMA module at all. Looking
again at their datasheets, the CTARE register (which is specific to XSPI
functionality) seems to be documented, so switch them to XSPI mode
instead.

We always toggle the chip select manually in spi-geni-qcom so that we
can properly implement the Linux API. There's no reason to program
this to the hardware on every transfer. Program it once at init and
be done with it.
This saves some part of a microsecond of overhead on each transfer.
While not really noticeable on any real world benchmarks, we might as
well save the time.

In commit 902481a78ee4 ("spi: spi-geni-qcom: Actually use our FIFO") I
explained that the maximum size we could program the FIFO was
"mas->tx_fifo_depth - 3" but that I chose "mas->tx_fifo_depth()"
because I was worried about decreased bandwidth.
Since that time:
* All the interconnect patches have landed, making things run at the
proper speed.
* I've done more measurements.
This lets me confirm that there's really no downside of using the FIFO
more. Specifically I did "flashrom -p ec -r /tmp/foo.bin" on a
Chromebook and averaged over several runs.
Before: It took 6.66 seconds and 59669 interrupts fired.
After: It took 6.66 seconds and 47992 interrupts fired.

would be great if you can give them a try. I wasn't able to test them
due to lack of hardware.

The series add support for the Sparx5 SoC SPI controller in the
spi-dw-mmio.c spi driver.
v5 changes:
- rx-sample-delay-ns documentation changes from Rob Herring:
- Drop superfluous type $ref
- Add default value = 0
v4 changes:
- Changed snps,rx-sample-delay-ns to snps,rx-sample-delay-ns
suggested by Rob Herring (rockchip also has this property).
- Added support for controller-level rx-sample-delay-ns value as
well as per SPI slave value (rockchip has controller-level property).
- Dropped internal mux in favor of suggested spi-mux to
control bus inteface selection.
v3 changes:
- Added mux support for controlling SPI bus interface. This is new mux
driver, bindings and added to sparx5 base DT.
- Removed "microchip,spi-interface2" property in favour of
"mux-controls" property in SPI controller (sparx5 only).
- Changed dw_spi_sparx5_set_cs() to use the mux control instead of
directly acessing "mux" register. Associated code/defines moved to mux
driver.
- Changed dw_spi_sparx5_set_cs() to match other similar functions in
signature and avoid explicit CS toggling.
- Spun off duplicated NAND device DT chunks into separate DT file.
v2 changes:
- Moved all RX sample delay into spi-dw-core.c, using
the "snps,rx-sample-delay-ns" device property.
- Integrated Sparx5 support directly in spi-dw-mmio.c
- Changed SPI2 configuration to per-slave "microchip,spi-interface2"
property.
- Added bindings to existing snps,dw-apb-ssi.yaml file
- Dropped patches for polled mode and SPI memory operations.

This adds SPI support for the Sparx5 SoC, which is using the MMIO
Designware SPI controller.
The Sparx5 differs from the Ocelot version in these areas:
* The CS override is controlled by a new set of registers for
this purpose.
* The Sparx5 SPI controller has the RX sample delay register, and it
must be configured for the (SPI NAND) device on SPI2.
* The Sparx5 SPI controller has 2 different SPI bus interfaces on the
same controller (don't ask...). The "spi-mux" driver should be used
in conjunction with the SPI driver to select the appropriate bus.

This add support for the RX_SAMPLE_DLY register. If enabled in the
Designware IP, it allows tuning of the rx data signal by means of an
internal rx sample fifo.
The register is controlled by the rx-sample-delay-ns DT property,
which is defined per SPI slave as well on controller level.
The controller level rx-sample-delay-ns will apply to all slaves
without the property explicitly defined.
The register is located at offset 0xf0, and if the option is not
enabled in the IP, changing the register will have no effect. The
register will only be written if any slave defines a nonzero value
(after scaling by the clock period).

'clang-format-for-linus-v5.9-rc4' and 'compiler-attributes-for-linus-v5.9-rc4' of git://github.com/ojeda/linux
Pull misc fixes from Miguel Ojeda:
"A trivial patch for auxdisplay:
- Replace HTTP links with HTTPS ones (Alexander A. Klimov)
The usual clang-format trivial update:
- Update with the latest for_each macro list (Miguel Ojeda)
And Luc requested me to pick a sparse fix on my queue, so here it goes
along with other two trivial Compiler Attributes ones (also from Luc).
- sparse: use static inline for __chk_{user,io}_ptr() (Luc Van
Oostenryck)
- Compiler Attributes: fix comment concerning GCC 4.6 (Luc Van
Oostenryck)
- Compiler Attributes: remove comment about sparse not supporting
__has_attribute (Luc Van Oostenryck)"

Pull power management fixes from Rafael Wysocki:
"These fix reference counting in the operating performance points (OPP)
framework and address a few intel_pstate driver issues, mostly related
to switching driver operation modes and similar with hardware-managed
P-states (HWP) enabled.
Specifics:
- Fix reference counting of operating performance points (OPP) tables
(Viresh Kumar).
- Address intel_pstate driver interface issues, mostly related to
switching operation modes and handling CPU offline and online and
system-wide suspend/resume with hardware-managed P-states (HWP)
enabled (Rafael Wysocki).
- Fix the maximum frequency computation in the intel_pstate driver
with turbo P-states disabled by the platform firmware and HWP
enabled (Francisco Jerez)"
