| | * regulator: Improve WM831x DVS VSEL selection algorithmMark Brown2011-07-281-37/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than using the maximum voltage we get passed to select the DVS voltage to use remember the highest voltage we've ever seen. This improves how the driver works when the consumer permits higher voltages than it will ever selects in order to support the widest possible voltage range.

| | * regulator: tps65910: Fix array access out of bounds bugAxel Lin2011-07-221-12/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For tps65910, the number of regulator is 13. ( ARRAY_SIZE(tps65910_regs) is 13) For tps65911, the number of regulator is 12. ( ARRAY_SIZE(tps65911_regs) is 12) If we are using this driver for tps65911, we hit array access out of bounds bug in tps65910_probe() because current implementation always assume the number of regulator is 13 and thus it will access tps65911_regs[12]. Fix it by setting correct num_regulators for both chips in tps65910_probe(), and allocated neccessay memory accordingly.

| | * regulator: Refactor supply implementation to work as regular consumersMark Brown2011-06-091-65/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the regulator supply implementation is somewhat complex and fragile as it doesn't look like standard consumers but is instead a parallel implementation. This causes issues with locking and reference counting. Move the implementation over to using standard consumers to address this. Rather than only notifying the supply on the first enable/disable we do so every time the regulator is enabled or disabled, simplifying locking as we don't need to hold a lock on the consumer we are about to enable.

This means that the delays which the enables implement can all run in parallel, though it does mean that the order in which the supplies come on may be unstable. For super bonus fun points if any of the regulators are shared between multiple supplies on the same device (as is rather likely) then this will test our locking. Note that in this case we only delay once for each physical regulator so the threads shouldn't block each other while delaying. It'd be even nicer if we could coalesce writes to a shared enable registers in PMICs but that's definitely future work, and it may also be useful and is certainly more achievable to optimise out the parallelism if none of the regulators implement ramp delays.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding support for the twl6025. Major difference in the twl6025 is the group functionality has been removed from the chip so this affects how regulators are enabled and disabled. The names of the regulators also changed. The DCDCs of the 6025 are software controllable as well. Since V1 Use the features variable passed via platform data instead of calling global function. Change the very switch like if statements to be a more readable switch statement. Since V2 twl6025 doesn't use remap so remove it from the macros. Since V3 enable/disable functions for 4030/6030 were seperated upstream so rebase on top of this. Change DCDC reference to SMPS as this is used in TRM. Change list_voltage slightly to have less code.

* Revert "regulator: Move VCOINCELL to be the last element of ↵Axel Lin2011-05-271-1/+1
| | | | | | | | | | | | | mc13892_regulators array" I check this patch again and found this actually is not a bug because MC13xxx_DEFINE explictly defines the order of each entry in the array. Thus revert the patch. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
* regulator: Remove some unused variables from wm831x DCDCsMark Brown2011-05-271-2/+0
| | | | | | | | | These became unused with the IRQ removal patch, I'm fairly sure that a patch was sent earlier by someone else but it doesn't seem to have been applied and I don't have a copy sitting around any more.

* TPS65910: Add tps65910 regulator driverGraeme Gregory2011-05-273-0/+712
| | | | | | | | | | | The regulator module consists of 3 DCDCs and 8 LDOs.

* regulator: Use mc13xxx_reg_write instead of mc13xxx_reg_rmw in ↵Axel Lin2011-05-271-6/+10
| | | | | | | | | | | | mc13892_sw_regulator_set_voltage Currently, we call mc13xxx_reg_read and mc13xxx_reg_rmw for the same register. This can be converted to simply a mc13xxx_reg_read and a mc13xxx_reg_write, thus save a redundant register read.
