2019-07-02mfd: cros_ec_dev: Register cros_ec_accel_legacy driver as a subdeviceGwendal Grignou1-0/+69
With this patch, the cros_ec_ctl driver will register the legacy accelerometer driver (named cros_ec_accel_legacy) if it fails to register sensors through the usual path cros_ec_sensors_register(). This legacy device is present on Chromebook devices with older EC firmware only supporting deprecated EC commands: - Glimmer based devices [Intel SOC using LPC transport] - Veyron minnie devices [ARM SOC using SPI transport] Tested-by: Gwendal Grignou <[email protected]> Signed-off-by: Enric Balletbo i Serra <[email protected]> Reviewed-by: Andy Shevchenko <[email protected]> Signed-off-by: Gwendal Grignou <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2019-07-02mfd: rk808: Prepare rk805 for poweroffStefan Mavrodiev2-15/+36
RK805 has SLEEP signal, which can put the device into SLEEP or OFF mode. The default is SLEEP mode. However, when the kernel performs power-off (actually the ATF) the device will not go fully off and this will result in higher power consumption and inability to wake the device with RTC alarm. The solution is to enable pm_power_off_prepare function, which will configure SLEEP pin for OFF function.

2019-07-02mfd: rk808: Check pm_power_off pointerStefan Mavrodiev2-6/+12
The function pointer pm_power_off may point to function from other module (PSCI for example). If rk808 is removed, pm_power_off is overwritten to NULL and the system cannot be powered off. This patch checks if pm_power_off points to a module function. Signed-off-by: Stefan Mavrodiev <[email protected]> Signed-off-by: Lee Jones <[email protected]>
2019-07-02mfd: cros_ec: differentiate SCP from EC by feature bitPi-Hsun Shih2-0/+11
System Companion Processor (SCP) is Cortex M4 co-processor on some MediaTek platform that can run EC-style firmware. Since a SCP and EC would both exist on a system, and use the cros_ec_dev driver, we need to differentiate between them for the userspace, or they would both be registered at /dev/cros_ec, causing a conflict.

2019-07-02mfd: arizona: Fix undefined behaviorArnd Bergmann1-1/+1
When the driver is used with a subdevice that is disabled in the kernel configuration, clang gets a little confused about the control flow and fails to notice that n_subdevs is only uninitialized when subdevs is NULL, and we check for that, leading to a false-positive warning: drivers/mfd/arizona-core.c:1423:19: error: variable 'n_subdevs' is uninitialized when used here [-Werror,-Wuninitialized] subdevs, n_subdevs, NULL, 0, NULL); ^~~~~~~~~ drivers/mfd/arizona-core.c:999:15: note: initialize the variable 'n_subdevs' to silence this warning int n_subdevs, ret, i; ^ = 0 Ideally, we would rearrange the code to avoid all those early initializations and have an explicit exit in each disabled case, but it's much easier to chicken out and add one more initialization here to shut up the warning.
