The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_AS3722 drivers/mfd/Kconfig: bool "ams AS3722 Power Management IC" ...meaning that it currently is not being built as a module by anyone. In response to an earlier patch set suggesting removal of the unused modular code, Laxman suggested that this driver be instead moved to tristate. We do that here, and confirm it can build and modpost as a tristate. However there remains to be runtime testing in order to ensure this change is 100% functional for "=m".

Add support for handling IRQs: power button, AC and USB power state changes. Mask and interrupt bits are shared within one register, which prevents us to use regmap_irq implementation. New irq_domain is created in order to add interrupt handling for each tps65217's subsystem. IRQ resources have been added for charger subsystem to be able to notify about AC and USB state changes.

This patch adds common driver for the Top block of the Samsung Exynos SoC Low Power Audio Subsystem. This is a minimal driver which prepares resources for IP blocks like I2S, audio DMA and UART and exposes a regmap for the Top block registers. Also system power ops are added to ensure the Audio Subsystem is operational after system suspend/resume cycle.

The MFD_VEXPRESS_SYSREG driver selects CLKSRC_MMIO, which in turn conflicts with ARCH_USES_GETTIMEOFFSET, causing a harmless Kconfig warning when it is set: warning: (ARCH_MVEBU && ARCH_DIGICOLOR && ARCH_GEMINI && ARCH_KEYSTONE && ARCH_MOXART && ARCH_MXS && PLAT_SPEAR && ARCH_SUNXI && ARCH_TEGRA && ARCH_U300 && PLAT_ORION && ARCH_CLPS711X && ARCH_EP93XX && ARCH_NETX && ARCH_IXP4XX && ARCH_KS8695 && ARCH_W90X900 && ARCH_PXA && ARCH_SA1100 && ARCH_OMAP1 && ARCH_BCM_IPROC && ARCH_INTEGRATOR_AP && ARCH_OMAP2PLUS && MFD_VEXPRESS_SYSREG) selects CLKSRC_MMIO which has unmet direct dependencies (!ARCH_USES_GETTIMEOFFSET) This was apparently hidden by the fact that no ARM platform that still sets ARCH_USES_GETTIMEOFFSET has gpiolib support, and we already have a dependency on GPIOLIB that I added a while ago. However, after 296ad4ac ("gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"), any platform can enable CONFIG_GPIOLIB, and that lets us enable MFD_VEXPRESS_SYSREG as well. This adds an explicit dependency on !ARCH_USES_GETTIMEOFFSET to guarantee that we can enable the CLKSRC_MMIO driver without getting warnings.

The axp20x driver assumes the device is i2c based. This is not the case with later chips, which use a proprietary 2 wire serial bus by Allwinner called "Reduced Serial Bus". This patch follows the example of mfd/wm831x and splits it into an interface independent core, and an i2c specific glue layer. MFD_AXP20X and the new MFD_AXP20X_I2C are changed to tristate symbols, allowing the driver to be built as modules. Whitespace and other style errors in the moved i2c specific code have been fixed.

This driver supports the new Atmel Flexcom. The Flexcom is a wrapper which integrates one SPI controller, one I2C controller and one USART. Only one function can be enabled at a time. This driver selects the function once for all, when the Flexcom is probed, according to the value of the new "atmel,flexcom-mode" device tree property. This driver has chosen to present the Flexcom to the system as a MFD so the implementation is seamless for the existing Atmel SPI, I2C and USART drivers. Also the Flexcom embeds FIFOs: the latest patches of the SPI, I2C and USART drivers take advantage of this new feature.

The fix it, the CHROME_PLATFORMS dependencies were relexed on commit d12bbcd3 ("platform/chrome: Don't make CHROME_PLATFORMS depends on X86 || ARM") but that was found to be wrong and the correct fix is to add the needed dependencies to the MFD_CROS_EC config symbol. There are only x86 and ARM based Chromebooks so to avoid showing up the config option on unsupported platforms, make the symbol depend on these architectures. Also add a || COMPILE_TEST so it can have build coverage on other platforms.

The ChromeOS EC SPI and I2C transport drivers depends on CROS_EC_PROTO but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since these drivers already depend on MFD_CROS_EC and that config option already selects CROS_EC_PROTO, there is no need to make them explicitly depend on CROS_EC_PROTO since that dependency is already met.

The ChromeOS EC SPI transport driver has a dependency on OF because it uses some OF helpers from the <linux/of.h> header. But there isn't a need for an explicit dependency since the header has stub functions if CONFIG_OF is not defined. Also, MFD_CROS_EC_SPI already depends on MFD_CROS_EC which in turn has a dependency on OF so in practice can't be selected without CONFIG_OF.
