This v7 comprises all the patches that are still pending. //-- 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) 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 Changes since v4: - Removed regulator patches already applied / acked by Mark Brown - Input misc PEK driver: * Don't print anymore the "us" unit * Added cleanup for attributes when unbindind the device * Fixed error code returned when device_create_file() fails - DT: * Enable all the regulators on at boot-time * Removed min and max microvolts for all the regulators but DCDC2 * Moved the axp_ipsout regulator outside the MFD node - MFD core: * The supply regulators are now specified in the MFD driver using regulator_bulk_register_supply_alias() and the .parent_supplies in the MFD cell Changes since v5: - Added ACKs - Fixed compilation warning (reported by Hans De Goede) - Vendor-prefixes are now sorted - Removed DT patch Carlo Caione (6): mfd: AXP20x: Add bindings documentation dt-bindings: add vendor-prefix for X-Powers input: misc: Add driver for AXP20x Power Enable Key input: misc: Add ABI docs for AXP20x PEK 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 | 93 +++++++ .../devicetree/bindings/vendor-prefixes.txt | 1 + arch/arm/configs/multi_v7_defconfig | 3 + arch/arm/configs/sunxi_defconfig | 3 + drivers/input/misc/Kconfig | 11 + drivers/input/misc/Makefile | 1 + drivers/input/misc/axp20x-pek.c | 281 +++++++++++++++++++++ 8 files changed, 404 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 -- 1.9.1
