* regulator: Add pfuze driverSascha Hauer2017-01-203-0/+174
| | | | | | | | This is not yet a regulator driver, only the register map is exported as /dev/pfuze* so the registers can be accessed for debugging purposes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-1/+1
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* regulator: fixed: Init gpio properlySascha Hauer2016-02-231-0/+1
| | | | | | | gpio has to be initialized with an invalid gpio number. 0 is a valid number and it will be requested and used by the driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bcm2835: introduce mach-bcm283xAlexander Aring2016-01-042-3/+3
| | | | | | | | | | | | This patch changes the most part of mach-bcm2835 to mach-bcm283x. This prepares to add RPi2 support which is a bcm2836. This patch changes the Kconfig entry namens to BCM283X for drivers only. These drivers should working the same in bcm2836. While updating defconfig I added LED support/trigger option.

* regulator: Add support for regulator-boot-on device tree propertySascha Hauer2015-07-151-0/+15

* regulator: Factor out functions to work with regulator_internalSascha Hauer2015-07-151-41/+45
| | | | | | | | Internally we only have a struct regulator_internal, so factor out regulator_enable_internal and regulator_disable_internal functions which can be called from regulator internal code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* regulator: add bcm2835 driverJean-Christophe PLAGNIOL-VILLARD2015-02-043-0/+155
| | | | | | | | | | | this will allow to handle IP power automatically and not at board level Mainline kernel need this as they do not have the regulator driver support as some IP such as USB are not power on at boot Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* regulator: allow to use it with non DT deviceJean-Christophe PLAGNIOL-VILLARD2015-02-042-17/+83
| | | | | | | | | this will use the device name as regulator name with the same Algo as clkdev for lookup Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* sandbox: allow "make ARCH=sandbox allyesconfig"Holger Schurig2014-07-221-0/+1
| | | | | | | | | | | | | Compiling the tree with allyesconfig is helpful because different compilers (gcc, clang) or static checkers (e.g. clang's scan-build) can then process and check more code. This patch introduces two new configuration symbols that Kconfig files can depend on. That way, code that is only working where a cache or DMA implementation exists can be opted out.

* regulator: fixed: add always-on propertySteffen Trumtrar2014-07-111-0/+9
| | | | | | | | | Support the "regulator-always-on" property for fixed regulators. The regulator gets enabled on probe and subsequent disable calls are ignored. Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Add initial regulator supportSascha Hauer2014-04-294-0/+380
Provide minimal regulator support. Only supported operations are enabling and disabling regulators. Association of devices with their regulators is limited to devicetree only. If regulator support is disabled the API expands to static inline stubs so consumers can still use the API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
