1459fc5f6d Enable RTC driver.
The MC13783 MFD also contains an RTC. Enable it.
To avoid "No RTC device found, ALARM timers will not wake from suspend",
this patch is needed:

2e534b21a5 dmaengine: imx-sdma: pass sdma firmware name via platform data
It is not good to have cpu_name and to_version encoded into sdma
firmware name as variables.  For example, there are three TOs of
imx51 soc, the sdma script never changes since TO1, which means
all three TOs of imx51 uses TO1 version of sdma script.  But we
have to prepare three identical firmwares, sdma-imx51-to1.bin
sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel
capable of running on all three TOs.

The patch removes cpu_name and to_version from sdma platform data,
and instead uses fw_name to pass the firmware name, so that we can
pass the TO version where it's relevant and skip it where only one
firmware exists.

3622360430 ARM: mxc: clean up imx-dma device registration
The patch follows the implementation of gpio-mxc device registration
to break the concentrated imx-dma device registration into soc
specific setup function.  Then we can avoid the churn of "#ifdef"
and the cpu_is_mx checking on such a long list, which makes no sense,
considering more soc supports need to be added and we need to support
single image for multiple socs in the long run.

6d2385ab25 ARM: mach-imx/mx27_3ds: Do not annotate the chip select as internal
On the i.MX SPI driver the chipselect pins can be of the following types:

- internal: when the chipselect pin is used as a dedicated CS pin of the CSPI controller
- GPIO: a generic GPIO can be used as a chipselect funtion

On the mx27_3ds the SPI2 chip select is a GPIO, so don't annotate 'internal' in the chip select
definition.

In order to get the voltage for the LCD (2.8V and 1.8V) it is also necessary to turn on GPO1 and GPO3
supplies because they are connected to switches that enable these two voltages.

b2a08e3e46 ARM: mach-imx/mx31_3ds: Fix IOMUX for SPI1 signals
Original code was assuming that the CSPI1 pins on the
MX31PDK were the primary pin function, which is incorrect.

On MX31PDK board these are the pins that provide CSPI1 functionality:

DSR_DCE1 (ALT mode 1) --> CSPI1_CLK
RI_DCE1 (ALT mode 1) --> CSPI1_RDY

DTR_DTE1  -->CSI1_MOSI
DSR_DTE1 --> CSPI1_MISO
DTR_DCE2 ---> CSPI1_SS2

The 3 IOMUX settings above are done via GPR as per Table A-1 of the MX31RM.

This patch fixes the CSPI1 IOMUX and makes the LCD to be functional.

b78d8e59a6 gpio/mxc: Change gpio-mxc into an upstanding gpio driver
The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.

 * Add a list to save all mx2 ports references, so that
   mx2_gpio_irq_handler can walk through all interrupt status
   registers

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxc_gpio_init into mxc_gpio_probe function

 * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
   be public at all, and also make some other cleanup on
   plat-mxc/include/mach/gpio.h at the same time

And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

91350f6677 ARM: mxc: don't use the symbols in the CPU family choice to select others
The symbols in this choice should only be used to select between the
available machines that can be built into a single kernel. As these sets
(will) differ e.g. depending on ARM_PATCH_PHYS_VIRT and AUTO_ZRELADDR
letting them select other symbols makes the logic more complex and needs
to duplicate some things. So let the machines select the corresponding
symbols (indirectly via SOC_XYZ).

The cell's platform_data is now accessed with a helper function;
change clients to use that, and remove the now-unused data_size.

Note that mfd-core no longer makes a copy of platform_data, but the
mc13xxx-core driver creates the pdata structures on the stack.  In
order to get around that, the various ARM mach types that set the
pdata have been changed to hold the variable in static (global) memory.
Also note that __initdata references in aforementioned pdata structs
have been dropped.
