Subject[PATCH] regulator: lp87565: Enable LP87565_BUCK_CTRL_1_FPWM_MP_0_2
Date
Buck10 is a multi(dual) phase regulator. So as part of enabling it
turn on the LP87565_BUCK_CTRL_1_FPWM_MP_0_2 bit which forces it to
operate always in multiphase and forced-PWM operation mode.
This helps improve the transient voltage response while switching OPP.

Boot tested on dra76-evm and read the ctrl register after probe.

Applies on top of linux-next branch with

on top.
