Input: applespi - add dependency on LEDS_CLASS

2019-07-31T13:50:18+00:00

If applespi is enabled, but LEDs class support is not, the build fails:

drivers/input/keyboard/applespi.o: In function `applespi_probe':
applespi.c:(.text+0x1fcd): undefined reference to `devm_led_classdev_register_ext'

Add "depends on LEDS_CLASS" to the Konfig

Input: applespi - select CRC16 module

2019-07-23T13:48:58+00:00

In some rare randconfig builds, CRC16 is disabled, which leads
to a link error:

drivers/input/keyboard/applespi.o: In function `applespi_send_cmd_msg':
applespi.c:(.text+0x449f): undefined reference to `crc16'
drivers/input/keyboard/applespi.o: In function `applespi_verify_crc':
applespi.c:(.text+0x7538): undefined reference to `crc16'

This symbol is meant to be selected for each user in Kconfig,
so do that here as well.

Input: add Apple SPI keyboard and trackpad driver

2019-07-19T08:58:34+00:00

The keyboard and trackpad on recent MacBook's (since 8,1) and
MacBookPro's (13,* and 14,*) are attached to an SPI controller instead
of USB, as previously. The higher level protocol is not publicly
documented and hence has been reverse engineered. As a consequence there
are still a number of unknown fields and commands. However, the known
parts have been working well and received extensive testing and use.

In order for this driver to work, the proper SPI drivers need to be
loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci;
for all others they are spi_pxa2xx_platform and intel_lpss_pci.

Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2019-05-16T15:31:32+00:00

Pull ARM SoC platform updates from Olof Johansson:
 "SoC updates, mostly refactorings and cleanups of old legacy platforms.

  Major themes this release:

   - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)

   - Moving some of the ep93xx headers around to get it closer to
     multiplatform enabled.

   - Cleanups of Davinci

  This also contains a few patches that were queued up as fixes before
  5.1 but I didn't get sent in before release"

Input: qt1050 - add Microchip AT42QT1050 support

2019-05-07T21:12:43+00:00

Add initial support for the AT42QT1050 (QT1050) device. The device
supports up to five input keys, dependent on the mode. Since it adds only
the initial support, the "1 to 4 keys plus Guard Channel" mode isn't
supported.

ARM: ep93xx: keypad: stop using mach/platform.h

2019-04-29T06:08:35+00:00

We can communicate the clock rate using platform data rather than setting
a flag to use a particular value in the driver, which is cleaner and
avoids the dependency.

No platform in the kernel currently defines the ep93xx keypad device
structure, so this is a rather pointless excercise.  Any out of tree
users are probably dead now, but if not, they have to change their
platform code to match the new platform_data structure.

Input: snvs_pwrkey - make it depend on ARCH_MXC

2019-04-24T16:32:11+00:00

The SNVS power key is not only used on i.MX6SX and i.MX7D, it is also
used by i.MX6UL and NXP's latest ARMv8 based i.MX8M series SOC. So
update the config dependency to use ARCH_MXC, and add the COMPILE_TEST
too.
