2022-12-26T03:14:34Z

Follow the advice in Documentation/filesystems/sysfs.rst: show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space.

platform/chrome: Constify static attribute_group structs

2021-01-20T15:19:17Z

The only usage of these is to print their name in a dev_err-message, and to pass their address to sysfs_create_group() and sysfs_remove_group(), both which takes pointers to const. Make them const to allow the compiler to put them in read-only memory.

platform/chrome: wilco_ec: Platform data shouldn't include kernel.h

2020-02-11T09:32:50Z

Replace with appropriate types.h. Also there is no need to include device.h, but mutex.h. For the pointers to unknown structures use forward declarations. In the *.c files we need to include all headers that provide APIs being used in the module. Signed-off-by: Andy Shevchenko Signed-off-by: Enric Balletbo i Serra

USB PowerShare is a policy which affects charging via the special USB PowerShare port (marked with a small lightning bolt or battery icon) when in low power states: - In S0, the port will always provide power. - In S0ix, if usb_charge is enabled, then power will be supplied to the port when on AC or if battery is > 50%. Else no power is supplied. - In S5, if usb_charge is enabled, then power will be supplied to the port when on AC. Else no power is supplied.
