2022-04-04regulator: wm8994: Add an off-on delay for WM8994 variantJonathan Bakker1-3/+39
As per Table 130 of the wm8994 datasheet at [1], there is an off-on delay for LDO1 and LDO2. In the wm8958 datasheet [2], I could not find any reference to it. I could not find a wm1811 datasheet to double-check there, but as no one has complained presumably it works without it. This solves the issue on Samsung Aries boards with a wm8994 where register writes fail when the device is powered off and back-on quickly.

The reg-virt-consumer is very useful for development and testing of regulator drivers since it allows voltages and modes to be set from userspace. However, it currently requires platform data so it cannot be used without patching the kernel. Add support for probing it from the devicetree to remedy this. Since this driver is only meant for testing and is a purely software construct, no binding documentation is added.

2022-02-08regulator: core: fix false positive in regulator_late_cleanup()Oliver Barta1-10/+3
The check done by regulator_late_cleanup() to detect whether a regulator is on was inconsistent with the check done by _regulator_is_enabled(). While _regulator_is_enabled() takes the enable GPIO into account, regulator_late_cleanup() was not doing that. This resulted in a false positive, e.g. when a GPIO-controlled fixed regulator was used, which was not enabled at boot time, e.g. reg_disp_1v2: reg_disp_1v2 { compatible = "regulator-fixed"; regulator-name = "display_1v2"; regulator-min-microvolt = <1200000>; regulator-max-microvolt = <1200000>; gpio = <&tlmm 148 0>; enable-active-high; }; Such regulator doesn't have an is_enabled() operation. Nevertheless it's state can be determined based on the enable GPIO. The check in regulator_late_cleanup() wrongly assumed that the regulator is on and tried to disable it.

2022-01-28regulator: rpi-panel: Remove get_brightness hookDave Stevenson1-23/+0
The driver was implementing a get_brightness function that tried to read back the PWM setting of the display to report as the current brightness. The controller on the display does not support that, therefore we end up reporting a brightness of 0, and that confuses systemd's backlight service. Remove the hook so that the framework returns the current brightness automatically.

2022-01-06regulator: qcom_smd: Align probe function with rpmh-regulatorKonrad Dybcio1-30/+70
The RPMh regulator driver is much newer and gets more attention, which in consequence makes it do a few things better. Update qcom_smd-regulator's probe function to mimic what rpmh-regulator does to address a couple of issues: - Probe defer now works correctly, before it used to, well, kinda just die.. This fixes reliable probing on (at least) PM8994, because Linux apparently cannot deal with supply map dependencies yet.. - Regulator data is now matched more sanely: regulator data is matched against each individual regulator node name and throwing an -EINVAL if data is missing, instead of just assuming everything is fine and iterating over all subsequent array members. - status = "disabled" will now work for disabling individual regulators in DT. Previously it didn't seem to do much if anything at all.

Receiving the Over-Current Protection interrupt while the regulator is disabled does not count as unhandled/failure (IRQ_NONE, or 0 as it were) but a "fake event", usually due to inrush as the is regulator about to be enabled.

2021-12-15regulator: Introduce tps68470-regulator driverHans de Goede3-0/+211
The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in the kernel the Regulators and Clocks are controlled by an OpRegion driver designed to work with power control methods defined in ACPI, but some platforms lack those methods, meaning drivers need to be able to consume the resources of these chips through the usual frameworks. This commit adds a driver for the regulators provided by the tps68470, and is designed to bind to the platform_device registered by the intel_skl_int3472 module. This is based on this out of tree driver written by Intel: https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/regulator/tps68470-regulator.c with various cleanups added.

When an i2c remove callback fails, the i2c core emits a generic error message and still removes the device. Apart from the message there the return value isn't further used. So don't return an error code after having already emitted a driver specific warning about the problem to prevent two messages about the same issue.
