Tell the regulator framework to retrieve regulator init data from the 'regulator' subnode, or from the parent mfd device's platform data. Example: i2c0 { tps61052@33 { compatible = "ti,tps61052"; reg = <0x33>; regulator { regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; regulator-always-on; }; }; }; Tree: next-20191118 Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Link: https://lore.kernel.org/r/20191119154611.29625-3-TheSven73@gmail.com Signed-off-by: Mark Brown <broonie@kernel.org>
2019-11-19regulator: rn5t618: fix rc5t619 ldo10 enableAndreas Kemnade
LDO9 and LDO10 were listed with the same enable bits. That looks insane and there are no provisions in the code for handling such a special case. Also other out-of-tree drivers use a separate bit to enable it. Example: https://github.com/brunotl/kernel-kobo-mx6sl-ntx/blob/master/drivers/regulator/ricoh619-regulator.c So it seems to be clearly a bug. I cannot fully check it on my board without schematics and just discovered this during code analysis for another problem.

2019-11-07regulator: ab8500: Remove AB8505 USB regulatorStephan Gerhold
The USB regulator was removed for AB8500 in commit 41a06aa738ad ("regulator: ab8500: Remove USB regulator"). It was then added for AB8505 in commit 547f384f33db ("regulator: ab8500: add support for ab8505"). However, there was never an entry added for it in ab8505_regulator_match. This causes all regulators after it to be initialized with the wrong device tree data, eventually leading to an out-of-bounds array read. Given that it is not used anywhere in the kernel, it seems likely that similar arguments against supporting it exist for AB8505 (it is controlled by hardware). Therefore, simply remove it like for AB8500 instead of adding an entry in ab8505_regulator_match.

2019-10-01regulator: ti-abb: Fix timeout in ti_abb_wait_txdone/ti_abb_clear_all_txdoneAxel Lin
ti_abb_wait_txdone() may return -ETIMEDOUT when ti_abb_check_txdone() returns true in the latest iteration of the while loop because the timeout value is abb->settling_time + 1. Similarly, ti_abb_clear_all_txdone() may return -ETIMEDOUT when ti_abb_check_txdone() returns false in the latest iteration of the while loop. Fix it.

2019-09-23regulator: da9062: fix suspend_enable/disable preparationMarco Felsch
Currently the suspend reg_field maps to the pmic voltage selection bits and is used during suspend_enabe/disable() and during get_mode(). This seems to be wrong for both use cases. Use case one (suspend_enabe/disable): Those callbacks are used to mark a regulator device as enabled/disabled during suspend. Marking the regulator enabled during suspend is done by the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers. Setting this bit tells the DA9062 PMIC state machine to keep the regulator on in POWERDOWN mode and switch to suspend voltage. Use case two (get_mode): The get_mode callback is used to retrieve the active mode state. Since the regulator-setting-A is used for the active state and regulator-setting-B for the suspend state there is no need to check which regulator setting is active.

2019-09-23regulator: fixed: Prevent NULL pointer dereference when !CONFIG_OFAxel Lin
Use of_device_get_match_data which has NULL test for match before dereference match->data. Add NULL test for drvtype so it still works for fixed_voltage_ops when !CONFIG_OF.
