This has little practical impact since all real users of the regulator bindings use FDT which doesn't need the reference counting. - lots of cleanups, especially to the Samsung drivers. - support for Linear Technologies LTC3589, Texas Instruments TPS658640 and X-Powers AXP20x" * tag 'regulator-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (64 commits) regulator: pbias: remove unnecessary OOM messages regulator: max8649: remove unnecessary OOM messages regulator: core: Fix the init of DT defined fixed regulators regulator: core: Disable unused regulators after deferred probing is done regulator: Don't disable unused regulators we don't have permission for regulator: axp20x: Use regulator_map_voltage_ascend for LDO4 regulator: use of_property_read_{bool|u32}() regulator: Fix regulator_get_{optional,exclusive}() documentation regulators: Add definition of regulator_set_voltage_time() for !CONFIG_REGULATOR regulator: arizona-ldo1: add missing #include regulator: pfuze100: Support enable/disable for fixed regulator regulator: ltc3589: Remove ltc3589_list_voltage_fixed function regulator: ltc3589: Fix module dependency regulator: tps6586x: Remove unused to_tps6586x_dev() function regulator: tps65218: Convert to use regulator_set_voltage_time_sel regulator: tps6586x: Add support for the TPS658640 regulator: tps6586x: Prepare supporting fixed regulators regulator: pfuze100: Don't allocate an invalid gpio regulator: pfuze100: Support SWB enable/disable regulator: fixed: use of_property_read_{bool|u32}() ...

* | mfd: vexpress: Convert custom func API to regmapPawel Moll2014-05-151-38/+12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Components of the Versatile Express platform (configuration microcontrollers on motherboard and daughterboards in particular) talk to each other over a custom configuration bus. They provide miscellaneous functions (from clock generator control to energy sensors) which are represented as platform devices (and Device Tree nodes). The transactions on the bus can be generated by different "bridges" in the system, some of which are universal for the whole platform (for the price of high transfer latencies), others restricted to a subsystem (but much faster). Until now drivers for such functions were using custom "func" API, which is being replaced in this patch by regmap calls. This required: * a rework (and move to drivers/bus directory, as suggested by Samuel and Arnd) of the config bus core, which is much simpler now and uses device model infrastructure (class) to keep track of the bridges; non-DT case (soon to be retired anyway) is simply covered by a special device registration function * the new config-bus driver also takes over device population, so there is no need for special matching table for of_platform_populate nor "simple-bus" hack in the arm64 model dtsi file (relevant bindings documentation has been updated); this allows all the vexpress devices fit into normal device model, making it possible to remove plenty of early inits and other hacks in the near future * adaptation of the syscfg bridge implementation in the sysreg driver, again making it much simpler; there is a special case of the "energy" function spanning two registers, where they should be both defined in the tree now, but backward compatibility is maintained in the code * modification of the relevant drivers: * hwmon - just a straight-forward API change * power/reset driver - API change * regulator - API change plus error handling simplification * osc clock driver - this one required larger rework in order to turn in into a standard platform driver Signed-off-by: Pawel Moll <pawel.moll@arm.com> Acked-by: Mark Brown <broonie@linaro.org> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Mike Turquette <mturquette@linaro.org>

Implementation of the regulator framework driver for the Versatile Express voltage control. Devices without voltage constraints (ie. "regulator-[min|max]-microvolt" properties in the DT node) are treated as fixed (or rather read-only) regulators.
