3ce6e06202 Input: pinephone-keyboard - use devm_regulator_get_enable()
Use devm_regulator_get_enable() instead of hand writing it. It saves some
line of code.

d8bde56dfd Input: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

63c5eb157c Input: pinephone-keyboard - support the proxied I2C bus
The PinePhone keyboard case contains a battery managed by an integrated
power bank IC. The power bank IC communicates over I2C, and the keyboard
MCU firmware provides an interface to read and write its registers.
Let's use this interface to implement a SMBus adapter, so we can reuse
the driver for the power bank IC.
