Quoting Joseph Lo (2018-12-18 01:12:19) > The DFLL hardware supports two modes (I2C and PWM) for voltage control > when requesting a frequency. In this patch, we introduce PWM mode support. > > To support that, we re-organize the LUT for unifying the table for both > cases of I2C and PWM mode. And generate that based on regulator info. > For the PWM-based regulator, we get this info from DT. And do the same as > the case of I2C LUT, which can help to map the PMIC voltage ID and voltages > that the regulator supported. > > The other parts are the support code for initializing the DFLL hardware > to support PWM mode. Also, the register debugfs file is slightly > reworked to only show the i2c registers when I2C mode is in use. > > Based on the work of Peter De Schrijver <pdeschrijver@xxxxxxxxxx>. > > Signed-off-by: Joseph Lo <josephl@xxxxxxxxxx> > --- Acked-by: Stephen Boyd <sboyd@xxxxxxxxxx>
