platform/chrome: chromeos_tbmc - Remove unneeded const

2018-10-10T05:40:12Z

Clang warns: drivers/platform/chrome/chromeos_tbmc.c:102:14: warning: duplicate 'const' declaration specifier [-Wduplicate-decl-specifier] static const SIMPLE_DEV_PM_OPS(chromeos_tbmc_pm_ops, NULL, ^ ./include/linux/pm.h:365:56: note: expanded from macro 'SIMPLE_DEV_PM_OPS' ^ 1 warning generated. SIMPLE_DEV_PM_OPS is already declared as const, this one is unnecessary so remove it. Signed-off-by: Nathan Chancellor Signed-off-by: Benson Leung

platform/chrome: Add a new interrupt path for cros_ec_lpc

2018-10-10T04:44:44Z

This commit allows cros_ec_lpc to register a direct IRQ instead of relying on the ACPI notification chain to receive MKBP events. This change is done in the interest of allowing reduced jitter in the communication path between the CrOS EC and the host for receiving sensor data.

mfd: cros-ec: copy the whole event in get_next_event_xfer

2018-10-10T03:57:30Z

Commit 57e94c8b974db2d83c60e1139c89a70806abbea0 caused cros-ec keyboard events be truncated on many chromebooks so that Left and Right keys on Column 12 were always 0. Use ret as memcpy len to fix this. The old code was using ec_dev->event_size, which is the event payload/data size excluding event_type header, for the length of the memcpy operation. Use ret as memcpy length to avoid the off by one and copy the whole msg->data.

platform/chrome: Move mfd/cros_ec_lpc* includes to drivers/platform.

2018-09-07T07:56:36Z

The cros-ec-lpc driver lives in drivers/platform because is platform specific, however there are two includes (cros_ec_lpc_mec.h and cros_ec_lpc_reg.h) that lives in include/linux/mfd. These two includes are only used for the platform driver and are not really related to the MFD subsystem, so move the includes from include/linux/mfd to drivers/platform/chrome.

Immutable branch (mfd, chrome) due for the v4.19 window Immutable Branch which moves the cros_ec_i2c and cros_ec_spi transport drivers from mfd to platform/chrome. Changes in arm are a simple rename in defconfigs. Change in input is a rename in help text.

mfd: cros-ec: Increase maximum mkbp event size

2018-07-13T07:44:31Z

Having a 16 byte mkbp event size makes it possible to send CEC messages from the EC to the AP directly inside the mkbp event instead of first doing a notification and then a read.

platform/chrome: Move cros-ec transport drivers to drivers/platform.

2018-07-03T19:40:06Z

There are some cros-ec transport drivers (I2C, SPI) living in MFD, while others (LPC) living in drivers/platform. The transport drivers are more platform specific. So, move the I2C and SPI transport drivers to the platform/chrome directory. The patch also removes the MFD_ prefix of their Kconfig symbols.
