2021-04-14mfd: ene-kb3930: Make local symbol 'kb3930_power_off' staticWei Yongjun1-1/+1
The sparse tool complains as follows: drivers/mfd/ene-kb3930.c:36:15: warning: symbol 'kb3930_power_off' was not declared. Should it be static? The symbol is not used outside of this file.

2020-11-27mfd: ene-kb3930: Drop of_match_ptr from of_device_id tableKrzysztof Kozlowski1-1/+1
The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it is not relevant here). This fixes compile warning (!CONFIG_OF on x86_64): drivers/mfd/ene-kb3930.c:194:34: warning: ‘kb3930_dt_ids’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2020-09-30mfd: ene-kb3930: Add driver for ENE KB3930 Embedded ControllerLubomir Rintel1-0/+212
This driver provides access to the EC RAM of said embedded controller attached to the I2C bus as well as optionally supporting its slightly weird power-off/restart protocol. A particular implementation of the EC firmware can be identified by a model byte. If this driver identifies the Dell Ariel platform, it registers the appropriate cells.
