2020-03-16regulator: mp886x: Document MP8867 supportJisheng Zhang1-2/+4
MP8867 is an I2C-controlled adjustable voltage regulator made by Monolithic Power Systems. The difference between MP8867 and MP8869 are: 1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of MP8867 is determined by the I2C control. 2.For MP8867, when setting voltage, if the steps is within 5, we need to manually set the GO_BIT to 0.

2020-03-16regulator: add support for MP8869 regulatorJisheng Zhang3-0/+238
The MP8869 from Monolithic Power Systems is a single output DC/DC converter. The voltage can be controlled via I2C. Signed-off-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> Link: https://lore.kernel.org/r/20200316223020.1a6d92ae@xhacker Signed-off-by: Mark Brown <broonie@kernel.org>
