2012-08-15regulator: twl-regulator: fix up VINTANA1/VINTANA2Aaro Koskinen
It seems commit 2098e95ce9bb039ff2e7bf836df358d18a176139 (regulator: twl: adapt twl-regulator driver to dt) accidentally deleted VINTANA1. Also the same commit defines VINTANA2 twice with TWL4030_ADJUSTABLE_LDO and TWL4030_FIXED_LDO. This patch changes the fixed one to be VINTANA1. I noticed this when auditing my N900 boot logs. I could not notice any change in device behaviour, though, except that the boot logs are now like before: ... [ 0.282928] VDAC: 1800 mV normal standby [ 0.284027] VCSI: 1800 mV normal standby [ 0.285400] VINTANA1: 1500 mV normal standby [ 0.286865] VINTANA2: 2750 mV normal standby [ 0.288208] VINTDIG: 1500 mV normal standby [ 0.289978] VSDI_CSI: 1800 mV normal standby ...

2012-08-09regulator: core: request only valid gpio pins for regulator enableMarek Szyprowski
Commit 65f735082de3 ("regulator: core: Add core support for GPIO controlled enable lines") introduced enable gpio entry in regulator configuration structure. Some drivers use '-1' as a placeholder for marking that such gpio line is not available, because '0' is considered as a valid gpio number. This patch fixes initialization of such drivers (like MAX8952 on UniversalC210 board), when '-1' is provided as enable gpio pin in the regulator's platform data.

2012-08-08regulator: gpio-regulator: Split setting of voltages and currentsHeiko Stübner
Originally gpio-regulator used the first item of its state list that matched the given voltage or current range. Commit 4dbd8f63f0 (regulator: gpio-regulator: Set the smallest voltage/current in the specified range) changed this, to make the selection independent of the ordering of the state list. But selecting the minimal value is only true for voltage regulators. For current regulators the maximum in the given range should be selected instead. Therefore split the previous common selection function into specific functions for voltage and current regulators.

This patch fixes below issues when choosing selector: 1. Current code returns negative selector if min_uV < 900000 which is wrong. For example, it is possible to satisfy the request with selector = 1 if the requested min_uV is 850000. 2. Current code may select a voltage lower than requested min_uV. For example, if the requested min_uV is 945000, current code chooses selector = 1 which is lower than requested min_uV. DIV_ROUND_UP to avoid this case.

It should be 0 in this case.

Convert to devm_gpio_request to save a few error handling code. This patch properly handle the gpio_request failure, we should return error when gpio_request fails rather than just show warning. I think one of the reason we got -EBUSY is because current code does not free gpios in s5m8767_pmic_remove(). So it got -EBUSY when reload the module.
