* regulator: mc13xxx: Remove mc13xxx_sw_regulator_is_enabled functionAxel Lin2012-06-191-1/+0
| | | | | | | | | If .is_enabled callback is not implemented, regulator core assumes that the regulator is always on. Thus we don't need mc13xxx_sw_regulator_is_enabled function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

|\ | | | | | | Linux 3.4-rc2 contains some fixes that further patches depend upon.
| * regulator: Fix unbalanced lock/unlock in mc13892_regulator_probe error pathAxel Lin2012-03-261-5/+5
| | | | | | | | | | | | | | | | We do not hold a lock while registering regulator, thus should not call unlock if regulator_register fails. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* regulator: pass additional of_node to regulator_register()Rajendra Nayak2011-11-231-1/+1
| | | | | | | | | | | With device tree support for regulators, its needed that the regulator_dev->dev device has the right of_node attached. To be able to do this add an additional parameter to the regulator_register() api, wherein the dt-adapted driver can then pass this additional info onto the regulator core.

* regulator: Add module.h to drivers/regulator users as requiredPaul Gortmaker2011-10-311-0/+1
| | | | | | | | Another group of drivers that are taking advantage of the implicit presence of module.h -- and will break when we pull the carpet out from under them during a cleanup. Fix 'em now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* 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: 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.

* regulator: Move VCOINCELL to be the last element of mc13892_regulators arrayAxel Lin2011-05-271-1/+1
| | | | | | | | | | | | | | | | In include/linux/mfd/mc13892.h, we define MC13892_VCOINCELL as 23. Thus VCOINCELL should be defined as 23th element in mc13892_regulators array, not the first one. This actually fixes an off-by-one bug while accessing mc13892_regulators array. For example, In mc13892_regulator_probe, we use MC13892_VCAM as array index of mc13892_regulators array. mc13892_regulators[MC13892_VCAM].desc.ops->set_mode = mc13892_vcam_set_mode; Currently, it access mc13892_regulators[12] ,which is VAUDIO not VCAM.

* mfd: Use mfd cell platform_data for mc13xxx cells platform bitsSamuel Ortiz2011-05-261-3/+4
| | | | | | | | | | | | | With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

* mfd: mfd_cell is now implicitly available to mc13xxx driversAndres Salomon2011-03-231-4/+3
| | | | | | | | | | | | | | | The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
