* regulator: s2mps11: Optimize the regulator description macroAmit Daniel Kachhap2014-08-161-174/+85
| | | | | | | | | | | | | | | This patch makes the regulator description macro take minimum and steps voltage as parameter. In this way many repeated macros can be removed. Now these macros are repeated only if the the LDO/BUCK ctrl registers have non-linear positions. The good thing is these ctrl registers are mostly linear so they are not passed as parameters. This patch reduces the code size and also allow easy addition of more s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.

* regulator: s2mpxxx: Move regulator min/step voltages in common placeAmit Daniel Kachhap2014-08-161-25/+25
| | | | | | | | | | | This is a cleanup patch and moves min/step voltages in a common samsung header file so that they can be used by other s2mpxxx PMIC drivers. Only few required macros are added currently and others can be added if needed.

| | | | | | | | | | | | | | | | Add support for external control over GPIO for LDO10, LDO11 and LDO12 S2MPS14 regulators. External control can be turned on by writing 0x0 to control register which in case of other regulators is used for disabling them. These LDO10-LDO12 regulators can be disabled only by I2C GPIO or PWREN pin so the patch actually allows proper way of disabling them. Additionally the GPIO control has two benefits: - It is faster than toggling it over I2C bus. - It allows disabling the regulator during suspend to RAM; The AP will enable it during resume.

Additionally allocate array of of_regulator_match() dynamically (based on number of regulators) instead of allocation on the stack. This is needed for supporting different devices in s2mps11 driver and actually prepares the regulator driver for supporting the S2MPS14 device. Code for supporting the S2MPS14 device will add its own array of 'regulator_desc' (also marked as __initconst). This way memory footprint of the driver will be reduced (approximately 'regulators_desc' array for S2MPS11 occupies 5 kB on 32-bit ARM, for S2MPS14 will occupy 3 kB).
