2020-03-04regulator: Use driver_deferred_probe_timeout for regulator_init_complete_workJohn Stultz1-11/+14
The regulator_init_complete_work logic defers the cleanup for an arbitrary 30 seconds of time to allow modules loaded by userland to start. 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).

2020-03-04regulator: stm32-vrefbuf: fix a possible overshoot when re-enablingFabrice Gasnier1-1/+2
There maybe an overshoot, when disabling, then re-enabling vrefbuf too quickly. VREFBUF is used by ADC/DAC on some boards. When re-enabling too quickly, an overshoot on the reference voltage make the conversions inaccurate for a short period of time. - Don't put the VREFBUF in HiZ when disabling, to force an active discharge. - Enforce a 1ms OFF/ON delay Fixes: 0cdbf481e927 ("regulator: Add support for stm32-vrefbuf") Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Message-Id: <1583312132-20932-1-git-send-email-fabrice.gasnier@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertenly introduced[3] to the codebase from now on.

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.

2020-01-17regulator: vctrl-regulator: Avoid deadlock getting and setting the voltageEnric Balletbo i Serra2-15/+25
`cat /sys/kernel/debug/regulator/regulator_summary` ends on a deadlock when you have a voltage controlled regulator (vctrl). The problem is that the vctrl_get_voltage() and vctrl_set_voltage() calls the regulator_get_voltage() and regulator_set_voltage() and that will try to lock again the dependent regulators (the regulator supplying the control voltage). Fix the issue by exporting the unlocked version of the regulator_get_voltage() and regulator_set_voltage() API so drivers that need it, like the voltage controlled regulator driver can use it.

2020-01-03regulator: bd70528: Remove .set_ramp_delay for bd70528_ldo_opsAxel Lin1-1/+0
The .set_ramp_delay should be for bd70528_buck_ops only. Setting .set_ramp_delay for for bd70528_ldo_ops causes problem because BD70528_MASK_BUCK_RAMP (0x10) overlaps with BD70528_MASK_LDO_VOLT (0x1f). So setting ramp_delay for LDOs may change the voltage output, fix it.

A copy-paste error was introduced when bitmasks were converted to macros, incorrectly setting the enable bitmask for ELDO2 to the one for ELDO1 for the AXP22x units. Fix it by using the correct macro. On affected boards, ELDO1 and/or ELDO2 are used to power the camera, which is currently unsupported.

2019-12-17regulator: bd71828: Basic support for ROHM bd71828 PMIC regulatorsMatti Vaittinen3-0/+825
ROHM BD71828 is a power management IC containing 7 bucks and 7 LDOs. Bucks 1,2,6 and 7 can be assigned to a regulator group controlled by run-levels. Eg. Voltages and enable/disable statuses for specific run-levels (run0 to run3) can be set via register interface and run level changes can then be done either via I2C or GPIO. This initial commit does not support assigning bucks to be controlled via run-levels but only allows them to be individually controlled. LDO5 voltage can also be controlled by GPIO2 pin and register interfaces but this driver only supports the control via register.
