[PATCH v7 0/6] mfd: AXP20x: Add support for AXP202 and AXP209

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



During the merging of v6 several patches were left out. 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
