Register all normal regulators rather than skipping unconfigured ones now that the core can handle regulators without init data. Skip the boost and isink regulators since they are normally controlled by other drivers. Signed-off-by:Mark Brown <broonie@opensource.wolfsonmicro.com>

This patch converts tps65090 regulator driver to use generic regmap enable/disable operations. Also move struct tps65090 to include/linux/mfd/tps65090.h because the regulator driver needs to access the rmap field of struct tps65090. Signed-off-by:

Since the enable(), disable() and is_enabled() operations for most regmap based regulators come down to reading and updating a single register bit we can factor out the code and allow these drivers to just define which bit to update using the enable_reg and enable_mask fields in their desc and then use operations provided by the core. As well as the code saving this opens the door to future optimisation of the bulk operations - if the core can realise that we are updating a single register for multiple regulators then it should be able to combine these updates into a single physical operation.

Since the voltage selector operations are intended to directly map a bitfield in the device register map into regulator API operations the code for implementing them is usually very standard we can save some code by providing standard implementations for devices using the regmap API. Drivers using regmap can pass their regmap in in the regmap_config struct, set vsel_reg and vsel_mask in their regulator_desc and then use regulator_{get,set}_voltage_sel_regmap in their ops. This saves a small amount of code from each driver. Signed-off-by: -

Since many regulators use regmap for register I/O and since there's quite a few very common patterns in the code allow drivers to pass in a regmap to the core for use in generic code. Signed-off-by:

There's no need to implement set_voltage() as there is only a very small range of selectors for the regulators in the WM8994 and the voltages are not expected to vary frequently at runtime. Signed-off-by:

We don't support missing configs at all so segfaulting isn't that bad but since we've got checks in the code move the dereference after them. Signed-off-by: -

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. Signed-off-by:

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. Signed-off-by:
