| | | | * | regulator: lp872x: set the default DVS modeKim, Milo2012-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The lp872x driver has the DVS platform data which select the register address of the BUCK voltage. This patch enables updating the default DVS mode when the DVS platform data is not defined.

| | | | * | regulator: max8907: fix use of possibly NULL idataStephen Warren2012-08-28

In that case, during MAX8907 regulator's probe(), the idata variable will be NULL for that regulator. Prevent dereferincing it. If the MBATT regulator's init_data is not specified, or no name was specified in the constraints, the regulator will be named based on the regulator descriptor, so initialize mbatt_rail_name from there.

This is probably ok because a system contains only one instance of each regulator, but it's still bad style because any driver should be written to support multiple instances of the same hardware. This patch changes the code to dynamically allocate the memory we pass to the regulator core so the table can be constant.

When using equation to calculate vsel, we need to ensure the requested min_uV meet the range of using the equation. Otherwise we may select a voltage that is out of specified range. For example, in the case vsel = 62 means select voltage of 2100000uV. What we want is to ensure the requested min_uV <= 2100000 rather than checking max_uV >= 2100000. And this also means in the case min_uV > 2100000, vsel = 62 does not meet the request. Also calling twl6030smps_list_voltage() for all cases to ensure the selected voltage still in bounds.

| | | |/ | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many regulators support a bypass mode where they simply switch their input supply to the output. This is mainly used in low power retention states where power consumption is extremely low so higher voltage or less clean supplies can be used. Support this by providing ops for the drivers and a consumer API which allows the device to be put into bypass mode if all consumers enable it and the machine enables permission for this. This is not supported as a mode since the existing modes are rarely used due to fuzzy definition and mostly redundant with modern hardware which is able to respond promptly to load changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users (especially framework code) may end up passing in a zero deferral time depending on runtime conditions or configuration. If they do then just call regulator_disable() directly to save scheduling. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a regulator only supports a single voltage list_voltage() can be used to report what that voltage is so add this as one of the criteria for creating the microvolts file in sysfs.

| * | | regulator: core: Use list_voltage() to read single voltage regulatorsMark Brown2012-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the regulator doesn't supply a way of reading back the voltage but does provide a list_voltage() operation then use that with a selector of zero to read the voltage. Regulators doing this means that we have the list operation there for consumers that want to configure themselves.
