2017-06-07regulator: pwm: Fix handling of missing init voltageMark Kettenis
Since priv->init_voltage is an unsigned integer it can never be negative. So the current code fails to detect a missing 'regulator-init-microvolt' property and instead misconfigures the PWM device. Fix this by making the relevant members of 'struct pwm_regulator_info' signed integers. Signed-off-by: Mark Kettenis <kettenis@openbsd.org>
2017-06-07power: rk808: fix ldo register offsetHeiko Stübner
Till now get_ldo_reg did a return &rk808_ldo[num - 1]; to return the ldo register offset but didn't take into account that its calling functions already created the ldo as ldo = dev->driver_data - 1. This resulted in the setting for ldo8 writing to the register of ldo7 and so on. So fix this and get the correct ldo register data.

2017-05-29drivers/power/regulator/max77686.c: Fix comparisons of unsigned expressionsTom Rini
Inside of max77686_buck_volt2hex/max77686_buck_hex2volt/max77686_ldo_volt2hex we check that the value we calculate is >= 0 however we declare 'hex' as unsigned int making these always true. Mark these as 'int' instead. We also move hex_max to int as they are constants that are 0x3f/0xff. Given that the above functions are marked as returning an int, make the variables we assign their return value to also be int to be able to catch the error condition now. Reported by clang-3.8.

2017-05-10power: regulator: pwm: support pwm polarity settingKever Yang
The latest kernel PWM drivers enable the polarity settings. When system run from U-Boot to kerenl, if there are differences in polarity set or duty cycle, the PMW will re-init: close -> set polarity and duty cycle -> enable the PWM. The power supply controled by pwm regulator may have voltage shaking, which lead to the system not stable.
