* regulator: Revert "Use driver_deferred_probe_timeout for ↵John Stultz2020-04-291-14/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | regulator_init_complete_work" This reverts commit dca0b44957e5 ("regulator: Use driver_deferred_probe_timeout for regulator_init_complete_work"), as we ended up reverting the default deferred_probe_timeout value back to zero, to preserve behavior with 5.6 we need to decouple the regulator timeout which was previously 30 seconds. This avoids breaking some systems that depend on the regulator timeout but don't require the deferred probe timeout.

This has made a mess which I only just noticed while preparing this and I can't see a sensible way to unpick things due to other subsequent merge commits especially the pull from MTD so it looks like the most sensible thing to do is give up and combine the two pull requests. Fortunately both subsystems were fairly quiet this cycle, the highlights are: regulator: - Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869 and Qualcomm PMI8994 and SMB208.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MP8867 is an I2C-controlled adjustable voltage regulator made by Monolithic Power Systems. The difference between MP8867 and MP8869 are: 1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of MP8867 is determined by the I2C control. 2.For MP8867, when setting voltage, if the step is within 5, we need to manually set the GO BIT to 0.

However currently they set control the SEL bits in the DVC registers, which causes the voltage to change to immediately between the "A" (normal) and "B" (standby) values as programmed and does nothing for the enable state... This means that "regulator-on-in-suspend" does not work (the regulator is switched off when the PMIC enters standby mode on the hardware signal) and, potentially, depending on the A and B voltage configurations the voltage could be incorrectly changed *before* actually entering suspend. The right bit to use for the functionality is the "CONF" bit in the "CONT" register. The detailed register description says "Sequencer target state" for this bit which is not very clear but the functional description is clearer. >From 5.1.5 System Enable: De-asserting SYS_EN (changing from active to passive state) clears control SYSTEM_EN which triggers a power down sequence into hibernate/standby mode ... With the exception of supplies that have the xxxx_CONF control bit asserted, all regulators in power domains POWER1, POWER, and SYSTEM are sequentially disabled in reverse order. Regulators with the <x>_CONF bit set remain on but change the active voltage controlregisters from V<x>_A to V<x>_B (if V<x>_B is notalready selected).

This arbitrary timeout is similar to the driver_deferred_probe_timeout value, and its been suggested we align these so users have a method to extend the timeouts as needed. So this patch changes the logic to use the driver_deferred_probe_timeout value for the delay value if it is set (using a delay of 0 if it is not).

| * | regulator: bd718x7: Split driver to common and bd718x7 specific partsMatti Vaittinen2020-01-244-128/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Few ROHM PMICs allow setting the voltage states for different system states like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages. The parsing functions can be re-used by other ROHM chip drivers like bd71828. Split the generic functions from bd718x7-regulator.c to rohm-regulator.c and export them for other modules to use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to Stephen Boyd I today learned we can use platform_device_id to do device and module matching for MFD sub-devices! Do device matching using the platform_device_id instead of using explicit module_aliases to load modules and custom parent-data field to do module loading and sub-device matching.
