  This patch corrects the support for MMCSD card detection
  and read only feature for SoC DM355.

  EVMDM355_ECP_VA4.pdf, from Spectrum digital, suggests that
  Bit 2 and 4 should be checked for card detection. However
  on the EVM, bits 1 and 3 gives this status, for MMC/SD
  instance 0 and 1 respectively. The pdf also suggests that
  Bit 1 and 3 should be checked for write protection. However
  on the EVM bits 2 and 4 gives this status.

• 00b8ac409   Input: dm355evm_keys - fix kconfig symbol names ... Browse Code »

  The keypad driver for the DM355 EVM got slightly broken as it merged,
  since it moved from input/keyboard to input/misc and its Kconfig
  symbol changed. This patch copes with the changed Kconfig symbol.

  Basic MFD framework for the MSP430 microcontroller firmware used
  on the dm355evm board:

  - Provides an interface for other drivers: register read/write
  utilities, and register declarations.

  - Directly exports:
  * Many signals through the GPIO framework
  + LEDs
  + SW6 through gpio sysfs
  + NTSC/nPAL jumper through gpio sysfs
  + ... more could be added later, e.g. MMC signals
  * Child devices:
  + LEDs, via leds-gpio child (and default triggers)
  + RTC, via rtc-dm355evm child device
  + Buttons and IR control, via dm355evm_keys

  - Supports power-off system call. Use the reset button to power
  the board back up; the power supply LED will be on, but the
  MSP430 waits to re-activate the regulators.

  - On probe() this:
  * Announces firmware revision
  * Turns off the banked LEDs
  * Exports the resources noted above
  * Hooks the power-off support
  * Muxes tvp5146 -or- imager for video input

  Unless the new tvp514x driver (tracked for mainline) is configured,
  this assumes that some custom imager driver handles video-in.

  This completely ignores the registers reporting the output voltages
  on the various power supplies. Someone could add a hwmon interface
  if that seems useful.
