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.

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.

2019-12-09regulator: rk808: Lower log level on optional GPIOs being not availableMiquel Raynal1-1/+1
RK808 can leverage a couple of GPIOs to tweak the ramp rate during DVS (Dynamic Voltage Scaling). These GPIOs are entirely optional but a dev_warn() appeared when cleaning this driver to use a more up-to-date gpiod API. At least reduce the log level to 'info' as it is totally fine to not populate these GPIO on a hardware design. This change is trivial but it is worth not polluting the logs during bringup phase by having real warnings and errors sorted out correctly.

2019-12-09regulator: core: avoid unneeded .list_voltage callsCristian Marussi1-0/+4
Inside machine_constraints_voltage() a loop is in charge of verifying that each of the defined voltages are within the configured constraints and that those constraints are in fact compatible with the available voltages' list. When the registered regulator happens to be defined with a wide range of possible voltages the above O(n) loop can be costly. Moreover since this behaviour is triggered during the registration process, it means also that it can be easily triggered at probe time, slowing down considerably some module loading. On the other side if such wide range of voltage values happens to be also continuous and without discontinuity of any kind, the above potentially cumbersome operation is also useless. For these reasons, avoid such .list_voltage poll loop when regulator is described as 'continuous_voltage_range' as is, indeed, similarly already done inside regulator_is_supported_voltage().

This patch refactors buck modes into a header file so that device trees can make use of these mode constants. The new header filename uses da9063 because DA9063 was the earlier chip and its driver code will want updating at some point in a similar manner.

Set a default ramp delay value to the regulators with the worst case value. Signed-off-by: pascal paillet <p.paillet@st.com> Link: https://lore.kernel.org/r/20191113161529.27739-1-p.paillet@st.com Signed-off-by: Mark Brown <broonie@kernel.org>
2019-11-15regulator: core: Let boot-on regulators be powered offPascal Paillet1-1/+3
Boot-on regulators are always kept on because their use_count value is now incremented at boot time and never cleaned. Only increment count value for alway-on regulators. regulator_late_cleanup() is now able to power off boot-on regulators when unused.

2019-11-15regulator: core: Don't try to remove device links if add failedSaravana Kannan2-2/+7
device_link_add() might not always succeed depending on the type of device link and the rest of the dependencies in the system. If device_link_add() didn't succeed, then we shouldn't try to remove the link later on as it might remove a link someone else created.

2019-11-07regulator: ab8500: Remove AB8505 USB regulatorStephan Gerhold1-17/+0
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.
