Now fixed regulators that have their enable pin connected to a GPIO line can use the fixed regulator driver for regulator enable/disable control. The GPIO number and polarity information is passed through platform data. GPIO enable control is achieved using gpiolib.

This patch implements list_voltage for the pcf50644 regulator driver. As the voltages are linearly scaled the code to convert register values to voltages can be reused and most of the code can be shared with get_voltage.

Mark Brown authored
The regulator_enable() code wasn't actually checking that the machine constraints had given permission to enable the regulator. Add code to do that, but only if the regulator is not already on due to something like always_on or being left on at startup since in those cases there's no physical change being introduced and the constraint wouldn't make any sense. Also add matching code for disable(). We need to do less there since either regulator_enable() should have succeeded first or the board setup makes no sense.

The patch to add support for looking up consumers by device name had the side effect of causing us to require a device which is at best premature since at least cpufreq still operates outside the device model.

Mark Brown authored
Some consumers require complete control of the regulator and can't tolerate sharing it with other consumers, most commonly because they need to have the regulator actually disabled so can't have other consumers forcing it on. This new regulator_get_exclusive() API call allows these consumers to explicitly request this, documenting the assumptions that they are making. In order to simplify coding of such consumers the use count for regulators they request is forced to match the enabled state of the regulator when it is requested. This is not possible for consumers which can share regulators due to the need to keep track of the ownership of use counts. A new API call is used rather than an additional argument to the existing regulator_get() in order to avoid merge headaches with driver code in other trees.

In PXA3xx SoC family, V_CORE power doamin is supplied by BUCK1 that is controller by ADTV1 or ADTV2 register. By default, v1 and v2 has the same copy. If v1 or v2 is updated, the last value that is written to either register takes effect. It means that v1 and v2 has different copy. And the actual voltage output is determinated by last update on either register. DA9034/35 is binded with PXA3xx SoC family. While SoC is scaling OP or entering/exiting lower power mode, SoC needs to change voltage of V_CORE power doamin. In order to be efficient, POWER I2C (hardcode) mode could be enabled in SoC. In this mode, SoC will control v2 register directly. In original DA903x driver, software will only read regulator data from v1 register. But SoC controls v2 register directly. It results that v1 and v2 isn't synchronized. Wrong data will be read from v1 register. So access v2 register in da903x driver instead.

Follow the approach suggested by Russell King and implemented by him in the clkdev API and allow consumer device supply mapings to be set up using the dev_name() for the consumer instead of the struct device. In order to avoid making existing machines instabuggy and creating merge issues the use of struct device is still supported for the time being. This resolves problems working with buses such as I2C which make the struct device available late providing that the final device name is known, which is the case for most embedded systems with fixed setups. Consumers must still use the struct device when calling regulator_get(). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
