H Hartley Sweeten 60214f058f Input: ep93xx_keypad - update driver to new core support
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.

Hartley Sweeten 12f56c6889 ARM: 5775/1: ep93xx: add keypad core support
Add the core support needed by the ep93xx matrix keypad driver.

The keypad driver unfortunately was merged early and the core
support is missing.  The clkdev support has been resolved and
is now merged.  This adds the platform device to the ep93xx
core and supplies the functions needed to acquire/free the gpio
pins and actually enable/disable the controller peripheral.

Hartley Sweeten ebd00c08e2 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.

Hartley Sweeten 6531a991f9 ARM: 5754/1: ep93xx: update i2c support
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.

  * 16-bit resolution
  * Programmable pulse width (duty cycle), interval (frequency), and
    polarity

This adds the necessary core support as well as the driver.  A sysfs

Hartley Sweeten 701fac823e [ARM] 5578/1: ep93xx: add ep93xx-keypad clock
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.

Hartley Sweeten 02239f0a42 [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.

Matthias Kaehlcke ca8cbc8391 [ARM] 5552/1: ep93xx get_uart_rate(): use EP93XX_SYSCON_PWRCNT and EP93XX_SYSCON_PWRCN
ep93xx: get_uart_rate() uses the constants EP93XX_SYSCON_CLOCK_CONTROL
and EP93XX_SYSCON_CLOCK_UARTBAUD, which no longer exist. Use
EP93XX_SYSCON_PWRCNT and EP93XX_SYSCON_PWRCNT_UARTBAUD instead

Hartley Sweeten 4070243250 [ARM] 5528/1: ep93xx: add defines for dma clock magic numbers
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
needed.  Currently these bits are in the code as "magic"
numbers.  This changes all of them to named defines to
improve code readability.

Also, the EP93XX_SYSCON_CLOCK_CONTROL register is improperly
named.  In the EP93xx User's Guide this register is called
PwrCnt (Power Control).  All of the uses of this register
are associated with the clock support so this patch also
modifies the names to match the User's Guide.

Hartley Sweeten e3a6d01932 [ARM] 5526/1: ep93xx: usb driver cleanup
Cleanup the ohci-ep93xx driver.

1) Use the usb.h dbg() macro instead of pr_debug() so that
   the source filename is prefixed to the message and it is
   terminated with a linefeed.

2) Add error handling for the clk_get() call.

3) Update clkdev support so that the usb clock is matched by
   the dev_id instead of the con_id.

Ryan Mallon 6cb38c5f5d [ARM] 5523/1: ep93xx phys offset selection
This patch adds a Kconfig option to select between ep93xx boards which
boot from the SDRAM bank at 0x00000000 (SDCE3/SyncBoot) and those which
boot from 0xc0000000 (SDCE0). This corrects a problem which causes
invalid images to be built for boards which boot from 0xc0000000.

Hartley Sweeten ff05c0330b [ARM] 5509/1: ep93xx: clkdev enable UARTS
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
the clocks before the kernel has booted. It also assumes that the
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.

memory configuration, MACH_TYPE, and additional on-board
I2C devices. This patch merges all of them into one file.
