      Input: ep93xx_keypad - update driver to new core support · 60214f05
      由 H Hartley Sweeten 提交于 
      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.

      [ARM] 5592/1: ep93xx: cleanup platform header includes · 583ddafe
      由 Hartley Sweeten 提交于 
      arch/arm/mach-ep93xx/include/mach/hardware.h
  1. Properly name the include files so that they are loaded
     from the <mach/*> directory and not the local directory.
  2. Remove including the ts72xx.h header.  This header is not
     generic to the ep93xx platform.  It should only be included
     by the ts72xx specific files that require it.  The only
     two users in the tree are arch/arm/mach-ep93xx/ts72xx.c
     and drivers/mtd/nand/ts7250.c.

arch/arm/mach-ep93xx/include/mach/ts72xx.h
  1. <linux/io.h> should already be included by any user of this
     header.  Doing the include here hides it from being needed
     by the calling source file.

arch/arm/mach-ep93xx/core.c
  1. Remove unnecessary headers.  They were probably included
     originally due to cut-and-paste from other files.
  2. <linux/io.h> should be included not <mach/gpio.h>

arch/arm/mach-ep93xx/adsphere.c
arch/arm/mach-ep93xx/edb93xx.c
arch/arm/mach-ep93xx/gesbc9312.c
arch/arm/mach-ep93xx/micro9.c
arch/arm/mach-ep93xx/ts72xx.c
  1. Remove unnecessary headers.

arch/arm/mach-ep93xx/ts72xx.c
  1. Remove unnecessary headers.
  2. Add platform specific header <mach/ts72xx.h>.

drivers/mtd/nand/ts7250.c
  1. <linux/io.h> should be included not <asm/io.h>.
  2. Add platform specific header <mach/ts72xx.h>.

      [ARM] 5578/1: ep93xx: add ep93xx-keypad clock · 701fac82
      由 Hartley Sweeten 提交于 
      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 · 02239f0a
      由 Hartley Sweeten 提交于 
      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.

      [ARM] pass reboot command line to arch_reset() · be093beb
      由 Russell King 提交于 
      OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

      [ARM] remove a common set of __virt_to_bus definitions · b5ee9002
      由 Nicolas Pitre 提交于 
      Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.
