Make sure that we patch the ACCCTL register as the first thing when the driver loads, thus configuring I2C fast mode and i2c access for dual access registers. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

In certain boards the source for the clk32k clock can be gated. In these boards the clk32k clock can be provided to the driver and it is going to be enabled/disabled when it is needed. If the clk32k clock is not provided the driver will assume that it is always running. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

All boards using twl6040 configures the i2c bus to 400KHz. While twl6040's defaults to normal mode (100KHz). So far twl6040 has no problem with i2c communication in this configuration it is safer to select fast i2c mode.

If for some reason the boot loader enabled the audpwron GPIO we will have pending IRQs to be handled. This seams to break twl6040 for some reason leading to non working i2c communication (i2c timeouts). Clearing the INTID register after we requested the audpwron GPIO (and set it to low) will ensure that the chip will operate normally in this case as well.

The supply aliases for the MFD devices were being added using devres but the device hasn't been added at this point and as such we can't use devres. The MFD already has a function that removes devices this patch uses the non-devres versions of the supply alias functions and adds an unregister in mfd_remove_devices_fn.

The valid gpio is GPIO0 ~ GPIO58, so ngpio should be 59. This patch also renames RDC321X_MAX_GPIO to RDC321X_NUM_GPIO because it actually means the number of available GPIOs.

The rtc-s5m driver does not support all of S2M and S5M chipsets supported by main MFD sec-core driver. For such chipsets unsupported by rtc-s5m, the MFD sec-core driver initialized regmap with default config. This config in such cases wouldn't work at all. The main MFD sec-core driver shouldn't initialize regmap for child drivers which is not used by them and even not valid. Move the allocation of RTC I2C dummy device and initialization of RTC regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m driver will use proper regmap config for supported devices.

After request_threaded_irq() is called there is a chance that an interrupt may occur before the 'mc13xxx->lock' is initialized, which will trigger a kernel oops. In order to prevent that, move the initialization of 'mc13xxx->lock' prior to requesting the interrupts.

The TPS658640 has a different set of output voltage for most LDO and the RTC LDO isn't settable. This chip also report 2 different version ID, as the datasheet doesn't list the possible values the second ID has simply been named TPS658640v2.

Pull two powerpc fixes from Ben Herrenschmidt: "Here are a couple of fixes for 3.15. One from Anton fixes a nasty regression I introduced when trying to fix a loss of irq_work whose consequences is that we can completely lose timer interrupts on a CPU... not pretty. The other one is a change to our PCIe reset hook to use a firmware call instead of direct config space accesses to trigger a fundamental reset on the root port. This is necessary so that the FW gets a chance to disable the link down error monitoring, which would otherwise trip and cause subsequent fatal EEH error" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc: irq work racing with timer interrupt can result in timer interrupt hang powerpc/powernv: Reset root port in firmware
