The Ricoh RN5T567 is from the same family as the Ricoh RN5T618 is, the differences are: + DCDC4/DCDC5 + LDO7-10 + Slightly different output voltage/currents + 32kHz Output + RTC + USB Charger detection Signed-off-by: Pierre-Hugues Husson <phh@phh.me> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

The AXP806 supports either master/standalone or slave mode. Slave mode allows sharing the serial bus, even with multiple AXP806 which all have the same hardware address. This is done with extra "serial interface address extension", or AXP806_BUS_ADDR_EXT, and "register address extension", or AXP806_REG_ADDR_EXT, registers. The former is read-only, with 1 bit customizable at the factory, and 1 bit depending on the state of an external pin. The latter is writable. Only when the these device addressing bits (in the upper 4 bits of the registers) match, will the device respond to operations on its other registers. Add these 2 registers to the regmap so we can access them. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

The new sun4i mfd driver is lacking a dependency, triggering very rarely int randconfig kernel builds: drivers/mfd/sun4i-gpadc.o: In function `sun4i_gpadc_probe': sun4i-gpadc.c:(.text.sun4i_gpadc_probe+0x110): undefined reference to `devm_regmap_add_irq_chip' This adds a 'select REGMAP_IRQ', as the other drivers with this problem do.

The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config ABX500_CORE drivers/mfd/Kconfig: bool "ST-Ericsson ABX500 Mixed Signal Circuit register functions" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We replace module.h with init.h and export.h ; the latter since the file does export some symbols.

The kernel WARNs and then crashes today if wm8994_device_init() fails after calling devm_regulator_bulk_get(). That happens because there are multiple devices involved here and the order in which managed resources are freed isn't correct. The regulators are added as children of wm8994->dev. Whereas, devm_regulator_bulk_get() receives wm8994->dev as the device, though it gets the same regulators which were added as children of wm8994->dev earlier. During failures, the children are removed first and the core eventually calls regulator_unregister() for them. As regulator_put() was never done for them (opposite of devm_regulator_bulk_get()), the kernel WARNs at WARN_ON(rdev->open_count); And eventually it crashes from debugfs_remove_recursive(). Fix the kernel warnings and crashes by using regulator_bulk_get() instead of devm_regulator_bulk_get() and explicitly freeing the supplies in exit paths. Tested on Exynos 5250, dual core ARM A15 machine.

The Kconfig and file naming for the PM8xxx driver is totally confusing: - Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel users depending on or selecting either at random. - A driver file named pm8921-core.c even if it is indeed used by the whole PM8xxx family of chips. - An irqchip named pm8xxx since it was (I guess) realized that the driver was generic for all pm8xxx PMICs. As I may want to add support for PM8901 this is starting to get really messy. Fix this situation by: - Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX and convert all users, including LEDs Kconfig and ARM defconfigs for qcom and multi_v7 to use that single symbol. - Renaming the driver to qcom-pm8xxx.c to fit along the two other qcom* prefixed drivers. - Rename functions withing the driver from 8921 to 8xxx to indicate it is generic. - Just drop the =m config from the pxa_defconfig, I have no clue why it is even there, it is not a Qualcomm platform. (Possibly older Kconfig noise from saveconfig.)
