power: regulator: gpio-regulator: Convert to use APIs which support live DT

2020-10-23T17:33:07Z

Use ofnode_ or dev_ APIs instead of fdt_ and fdtdec_ APIs so that the driver can support live DT. Signed-off-by: Patrick Delaunay Reviewed-by: Simon Glass

power: regulator: gpio-regulator: protect count value

2020-10-23T17:33:06Z

Update the size of states_array to avoid overflow for dev_pdata->voltages[j] and dev_pdata->states[j]. As the size of array is GPIO_REGULATOR_MAX_STATES, the size of states_array is limited by GPIO_REGULATOR_MAX_STATES * 2 = 4 instead of 8 previously. The value of the "count" variable is limited by the third parameter of fdtdec_get_int_array_count. Signed-off-by: Patrick Delaunay Reviewed-by: Simon Glass

power: Tidy up inclusion of regulator_common.h

drivers: rename drivers to match compatible string

2020-07-10T00:57:22Z

When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

power: regulator: stm32: vrefbuf: fix a possible overshoot when re-enabling

2020-07-07T14:01:23Z

There maybe an overshoot: - when disabling, then re-enabling vrefbuf too quickly - or upon platform reset as external capacitor maybe slow discharging (VREFBUF is HiZ at reset by default). VREFBUF is used by ADC/DAC on some boards. An overshoot on the reference voltage make the conversions inaccurate for a short period of time. So: - Don't put the VREFBUF in HiZ when disabling, to force an active discharge. - Enforce a 1ms OFF/ON delay, also upon reset Penalty is a 1ms delay is applied (even for a cold boot), when enabling VREFBUF.

regulator: fix: enable gpio when requested

2020-06-15T20:37:01Z

The fix in commit b7adcdd073c0 has the side-effect that the regulator will be disabled when requesting the relevant gpio in regulator_common_ofdata_to_platdata() and enabled in regulator_pre_probe() when the regulator was already enabled. This leads to a short interruption in the 3.3V power to the PCIe slot on the firefly-rk3399 which makes an ADATA SX8000NP NVMe SSD unhappy. Fix this by setting the GPIOD_IS_OUT_ACTIVE flag again when the 'regulator-boot-on' property is set, but check for this property explicitly instead of relying on the "boot_on" member of the uclass platdata.
