That leads to problem with devices connected to vmmc2 regulator - when the device is rebooted from stock kernel vmmc2 is left in "sleep" mode (REGULATOR_STATUS_STANDBY in terms of regulator framework) and as noone in mainline kernel switches vmmc2 regulator to normal (REGULATOR_STATUS_NORMAL) mode, devices supplied by it does not get enough power to operate normally. Fix that by providing the correct functionality for initial mode setting from the board DTS. Fix i2c access to powerbus while at it. I will send a follow-up patch for N900 board DTS that sets initial regulators mode once the $subject series is assumed to be ok. Ivaylo Dimitrov (3): regulator: twl: Make sure we have access to powerbus before trying to write to it regulator: twl: Provide of_map_mode for twl4030 regulator: twl: Regulator mode should not depend on regulator enabled state drivers/regulator/twl-regulator.c | 100 +++++++++++++++++++++++++++++++------- 1 file changed, 82 insertions(+), 18 deletions(-) -- 1.9.1
