* regulator: twl-regulator: make TWL4030_ALLOW_UNSUPPORTED more configurable.NeilBrown2012-05-091-6/+4
| | | | | | | | | | | | | | | | | | | | The regulators in the twl4030 can provide some voltage settings that are not offically supported. These settings are disabled by default, but can be enabled with CONFIG_TWL4030_ALLOW_UNSUPPORTED=y However - that config variable is not mentioned in any Kconfig so cannot be used, and - a global setting is clumsy - a per regulator setting would be better. So define a new 'feature' flag that a board file can set to enable these unsupported volatages for boards which need them. This flag cannot (yet) be set using device-tree.

* regulator: Remove unneeded include of linux/delay.h from regulator driversAxel Lin2012-04-231-1/+0
| | | | | | | | | | | | | All the drivers that need delay for the regulator voltage output voltage to stabilize after being enabled or after being set to a new value has been converted to implement enable_time and set_voltage_time_sel callbacks. Then regulator core will take care of the necessary delay. For the drivers that don't need the delay, don't need to include linux/delay.h. This patch removes the unneeded include of linux/delay.h in regulator drivers. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* regulator: twl-regulator: Fix off-by-one vsel setting in twl6030smps_set_voltageAxel Lin2012-04-101-4/+10
| | | | | | | | | | | | | | commit 268a1 "regulator: twl-regulator: Use DIV_ROUND_UP at appropriate places" introduced an off-by-one bug for setting vsel. The linear calculation code in twl6030smps_list_voltage() does subtract index by 1 so we need the vsel++ after DIV_ROUND_UP. The original code use this trick to differentiate if we are going to set the voltage to 0 or the voltage falls within the linear calculation range.

| | | | | | | | | | | | This patch makes the code easier to read. Also add checking the case when no desc id is matched. This is required because if no desc id is matched, the poiner info is pointed to twl_of_match[i].data which may be not NULL. Checking info is NULL or not latter does not catch the error.

* regulator: core: Use a struct to pass in regulator runtime configurationMark Brown2012-04-091-2/+7
| | | | | | | | | | | | | | Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

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.

| | | | | | | | | | | | | | | | | | | | | | All twl6030 regulators can be programmed from 1.0v to 3.3v with 100mV steps. The below formula can be used to calculate the vsel values to be programmed in the VREG_VOLTAGE registers. Voltage(in mV) = 1000mv + 100mv * (vsel - 1) Ex: if vsel = 0x9, mV = 1000 + 100 * (9 -1) = 1800mV.
