This patch adds platform side support code for the EP93xx SPI
driver. This includes clock, resources and muxing. There is a new
function: ep93xx_register_spi() which can be used by board support
code to register new SPI devices for the board.

A number of the peripherals for the ep93xx are registered at
startup using platform_data that is passed from the board init
code to the core code. This data is then copied to a local
static variable in the core code. Since the data is copied,
the original data can be marked as __initdata and discarded
after startup is complete.
This adds the __initdata tag to all the appropriate data in
the various ep93xx board init's. Specifically, all the
struct ep93xx_eth_data, struct ep93xxfb_mach_info, and
struct i2c_gpio_platform_data.
Also, document the various registration functions and note
what data should be marked as __initdata.
While here, also cleanup a couple over zealous whitespace tabs.

The GPIO support in core.c handles the interrupt support for GPIO
ports A, B, and F. The gpiolib implementation in gpio.c needs to
access the function ep93xx_gpio_int_mask when a gpio pin is made
an output and ep93xx_gpio_update_int_params in order to update
the registers.
Moving this support from core.c to gpio.c allows making the two
functions static. It also keeps all the GPIO handling together in one
file.

This driver was merged before the ep93xx core support was added
for the keypad clock and acquiring/releasing the necessary gpio's.
Now that the proper support is in the ep93xx core this driver
needs to be updated to work correctly.
Summary of changes:
1) Remove some unused members from the platform data.
2) Remove the custom KEY macro and use the ones available in
<linux/input/matrix_keypad.h>
3) Remove the keypad_{readl/writel} macros and just use
__raw_{readl/writel} directly.
4) Update the clk_set_rate() call to work with the core support.
5) Cleanup the probe routine and remove some unneeded messages.
6) Use the ep93xx core functions to acquire and release the gpio's.
7) Fix the clk_get() call to get the keypad clock.

The clock generation system in the ep93xx uses two external oscillator's
and two internal PLLs to derive all the internal clocks. Many of these
internal clocks can be stopped to save power.
This introduces a "parent" hierarchy for the clocks so that the users
count can be correctly tracked for power management.
The "parent" for the video clock can either be one of the PLL outputs
or the external oscillator. In order to correctly track the "parent"
for the video clock calc_clk_div() needed to be modified. It now
returns an error code if the desired rate cannot be generated.

Update the ep93xx i2c support:
1) The platform init code passes the configuration data for the
i2c-gpio driver. This allows any gpio pin do be used for the
sda and scl pins. It also allows the platform to specify the
udelay and timeout.
2) Program the gpio configuration register to enable/disable the
open drain drivers. Note that this really only works if the
sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and
EP93XX_GPIO_LINE_EECLK.
3) Update the edb93xx.c platform init to use the new support.

Add clkdev support for the ep93xx_keypad driver.
A matrix keypad driver for the ep93xx just got merged via the
input subsystem group. For this driver to work the keypad clock
needs to be added to the ep93xx clkdev support. In order to
accomplish this the following changes are implemented:
1) Move the EP93XX_EXT_*_RATE defines to mach/include/hardware.h.
2) Add EP93XX_KEYTCHCLK_DIV{4/16} for the keypad driver.
3) Add support for programmable clocks (set_rate() callback).
4) Add clk_keypad for the keypad driver.
5) tab indent the clk_lookup table for easier reading.
6) Add the set_rate() callback to program the keypad clock.
This callback is generalized since the ADC clock (touchscreen)
can use the same callback.
7) Use the ep93xx_syscon_swlocked_write() core function for updating
the software locked register.

Add core functions to handle writes to the ep93xx software locked
registers.
There are a number of registers in the EP93xx System Controller
that require a write to the software lock register before they
can be updated. This patch adds a number of exported functions
to the ep93xx core that handle this access.
The software locked clock divider registers, VidClkDiv, MIRClkDiv,
I2SClkDiv and KeyTchClkDiv would typically involve writing a
specific value to the register. To support this the
ep93xx_syscon_swlocked_write() function is provided.
For the DeviceCfg register it's more typical to only need to
set or clear a single bit. A generic ep93xx_devcfg_set_clear()
function is provided to handle both operations. Two inline
functions, ep93xx_devcfg_set_bits() and ep93xx_devcfg_clear_bits()
are also provided to improve code readability.
In addition, the remaining bits in the System Controller Device
Config Register have been documented and the previously defined
names shortened.
All code paths that use this functionality have been updated
except for arch/arm/kernel/crunch.c. That code is in a context
switch path, which is not reentrant, so it is safe against itself.

Update the dma clocks so that the magic numbers are named.
All the dma clocks have an enable bit to turn them on/off as

Also, the EP93XX_SYSCON_CLOCK_CONTROL register is improperly

PwrCnt (Power Control). All of the uses of this register
are associated with the clock support so this patch also

The current implementation assumes that the bootloader has enabled
the clocks before the kernel has booted. It also assumes that the

Patch from Lennert Buytenhek
This patch adds support for the Cirrus Logic EDB9315A, an evaluation
board based on the Cirrus Logic EP9315 SoC, with 64M RAM, two USB host
ports, audio in/out, three serial ports, 10/100 ethernet, and IDE, VGA,
and LCD interfaces.
The EDB9315A is a low-cost version of the EDB9315, and has only 16M
of NOR flash, while the EDB9315 has 32M.

Patch from Lennert Buytenhek
This patch adds support for the Cirrus Logic EDB9302, an evaluation
board based on the Cirrus Logic EP9302 SoC, with 32M RAM, one USB host
port, audio in/out, two serial ports and a 10/100 ethernet interface.
George Kashperko submitted the original patch, this patch is a rewrite
using the newer physmap platform driver.

Patch from Lennert Buytenhek
The ep93xx ohci bits have been merged into the gregkh-2.6 tree, which
means that they will probably go upstream soon, so make the core ep93xx
code instantiate an appropriate ep93xx-ohci platform device.

Patch from Lennert Buytenhek
Add an initial implementation of the clk_* API for the cirrus ep93xx
to the tree. The initial implementation is somewhat minimal, with the
intention of extending it as we go along.

Patch from Lennert Buytenhek
The tick rate of timers 1-3 isn't exactly 508 kHz as some parts of the
relevant documentation claim, but more like 508.469 kHz (14.7456 MHz
divided by 29.)

Patch from Lennert Buytenhek
A couple of platforms aren't using the right comparison type in their
timer interrupt handlers (as we're comparing two wrapping timestamps,
we need a bmi/bpl-type comparison, not an unsigned comparison) -- this
patch fixes them up.

The recent renaming of m48t86's ->readb() and ->writeb() platform driver
methods (2d7b20c188) to ->readbyte() and
->writebyte() to fix the ia64 build broke the build of the cirrus ep93xx
ARM platform. This patch fixes it up.

Patch from Lennert Buytenhek
This patch adds support for the Cirrus ep93xx series of CPUs. The
ep93xx is an ARM920T based CPU with two VICs, PL010 based UARTs,
IrDA, MaverickCrunch floating point coprocessor, between 24 and 64
GPIOs, ethernet, OHCI USB and, depending on the model, pcmcia, raster
engine, graphics accelerator, IDE controller and a bunch of other
stuff.
This patch adds the core ep93xx support code, and support for the
Glomation GESBC-9312-sx and the Technologic Systems TS-72xx SBCs.
