usb: ohci: remove ep93xx bus glue platform driver
Convert ep93xx to use the OHCI platform driver and remove the
ohci-ep93xx bus glue driver.
Enable CONFIG_OHCI_HCD_PLATFORM in the ep93xx_defconfig so that USB
is still enabled by default on the EP93xx platform.

ARM: 6359/1: ep93xx: move clock initialization earlier
Commit 7cfe24947 ("ARM: AMBA: Add pclk support to AMBA bus
infrastructure") changed AMBA bus to handle the PCLK automatically.
However, in EP93xx clock initialization is arch_initcall which is done
later than AMBA device identification. This causes
amba_get_enable_pclk() to fail resulting device where UARTs are not
functional.
So change ep93xx_clock_init() to be postcore_initcall.

ARM: 5756/1: ep93xx: introduce clk parent
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.

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.

[ARM] 5577/2: ep93xx: syscon locked register functions
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.

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

Fix the clkdev API support for the ep93xx uart clocks.
The uarts available in the ep93xx have individual clock controls.
The current implementation assumes that the bootloader has enabled

bootloader has set the UARTBAUD bit indicating that the uarts are
running off the 14.7456MHz external crystal.
This fixes both issues. It also allows the uart clocks to be stopped
when there are no users.
