AXP209 and AXP202 are the PMUs (Power Management Unit) used by A10, A13 and A20 SoCs and developed by X-Powers, a sister company of Allwinner. AXP20x comprises an adaptive USB-Compatible PWM charger, 2 BUCK DC-DC converters, 5 LDOs, multiple 12-bit ADCs of voltage, current and temperature as well as 4 configurable GPIOs. This set of patches introduces the core driver and support for two different subsystems: - Regulators - PEK (Power Enable Key) This patchset depends on patchsets: irq: sun4i IRQ 0 / ENMI fixes (Hans de Goede) ARM: sun7i/sun6i: irqchip: Irqchip driver for NMI controller (Carlo Caione) regulator: helpers: Modify helpers enabling multi-bit control (Carlo Caione) Changes since v1: - Added a new standalone patch for defconfig - MFD core: * Removed axp,system-power-controller property - Bindings documentation: * Corrected description for dcdc-workmode property * Removed unused axp20x-pek compatible - Input misc PEK driver: * Fixed seconds in lower case - Regulators subsystem: * Fixed axp20x_set_suspend_voltage() * Switched to using multi-bit control for regulators * When "regulators" node is not found driver doesn't quit * Driver is now using devm_regulator_register() * Added module_platform_driver() instead of subsys_initcall() - DT: * Added new DTSI for AXP209 * Added support for cubietruck and olinuxino-micro Changes since v2: - Added a new patch for multi_v7_defconfig to enable MFD core and subsystems - DT: * Dropped axp,system-power-controller property from DTS * Moved compatible and interrupt-related properties from the DTSI file to the DTS board files - Regulators subsystem: * Deleted useless struct axp20x_regulators * Added a warning when out of specs values are used for the dcdc frequency - MFD core: * Fixed coding style * Removed IDs from device table for i2c - Bindings documentation: * Several corrections and fixes Changes since v3: - Removed x-powers-axp209.dtsi file - Rewritten bindings document - MFD core: * Fixed casting * Better comments / documentation - Input misc PEK driver: * Timings are now expressed in ms and the sysfs appies the closest possible value * No more useless pretty-printing * Removed devm_request_threaded_irq in favour of devm_request_any_context_irq * Moved from input attributes to platform device attributes - Regulators subsystem: * Removed suspend mode (axp20x_set_suspend_voltage) * Added regulators input supply - DT * DTs doesn't include anymore the dtsi * Added input supplies for regulators Carlo Caione (9): mfd: AXP20x: Add mfd driver for AXP20x PMIC dt-bindings: add vendor-prefix for X-Powers mfd: AXP20x: Add bindings documentation input: misc: Add driver for AXP20x Power Enable Key input: misc: Add ABI docs for AXP20x PEK regulator: AXP20x: Add support for regulators subsystem ARM: sun7i/sun4i: dt: Add AXP209 support to various boards ARM: sunxi: Add AXP20x support in defconfig ARM: sunxi: Add AXP20x support multi_v7_defconfig .../ABI/testing/sysfs-driver-input-axp-pek | 11 + Documentation/devicetree/bindings/mfd/axp20x.txt | 96 +++++++ .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/boot/dts/sun4i-a10-a1000.dts | 69 +++++ arch/arm/boot/dts/sun4i-a10-cubieboard.dts | 69 +++++ arch/arm/boot/dts/sun4i-a10-hackberry.dts | 75 ++++++ arch/arm/boot/dts/sun4i-a10-inet97fv2.dts | 69 +++++ arch/arm/boot/dts/sun4i-a10-mini-xplus.dts | 75 ++++++ arch/arm/boot/dts/sun4i-a10-olinuxino-lime.dts | 75 ++++++ arch/arm/boot/dts/sun4i-a10-pcduino.dts | 69 +++++ arch/arm/boot/dts/sun7i-a20-cubieboard2.dts | 70 +++++ arch/arm/boot/dts/sun7i-a20-cubietruck.dts | 70 +++++ arch/arm/boot/dts/sun7i-a20-olinuxino-micro.dts | 70 +++++ arch/arm/configs/multi_v7_defconfig | 3 + arch/arm/configs/sunxi_defconfig | 4 + drivers/input/misc/Kconfig | 11 + drivers/input/misc/Makefile | 1 + drivers/input/misc/axp20x-pek.c | 261 +++++++++++++++++++ drivers/mfd/Kconfig | 12 + drivers/mfd/Makefile | 1 + drivers/mfd/axp20x.c | 249 ++++++++++++++++++ drivers/regulator/Kconfig | 7 + drivers/regulator/Makefile | 1 + drivers/regulator/axp20x-regulator.c | 285 +++++++++++++++++++++ include/linux/mfd/axp20x.h | 180 +++++++++++++ 25 files changed, 1834 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-driver-input-axp-pek create mode 100644 Documentation/devicetree/bindings/mfd/axp20x.txt create mode 100644 drivers/input/misc/axp20x-pek.c create mode 100644 drivers/mfd/axp20x.c create mode 100644 drivers/regulator/axp20x-regulator.c create mode 100644 include/linux/mfd/axp20x.h -- 1.8.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
