[PATCH V2] mt_ventoux: support for TeeJet Mt.Ventoux board

Ilya Yanok yanok at emcraft.com
Tue Dec 27 18:09:37 EST 2011


This patch adds support for TeeJet Mt.Ventoux board based on TAM3517
SOM. Supported devices:
 - Serial
 - Ethernet
 - NAND
 - USB host
 - LCD
 - Touchscreen
 - CAN controller
 - ADC128S converter

Signed-off-by: Ilya Yanok <yanok at emcraft.com>

Changes from V1:

 - Fixed indentation (use tabs not spaces)
 - Fixed over 80 characters lines
 - Added #if defined(CONFIG_SENSORS_ADCXX_MODULE) to allow adcxx to be a
   module.
 - Fixes for compilation with CONFIG_TOUCHSCREEN_ADS7846!=y
  - Added defined(CONFIG_TOUCHSCREEN_ADS7846_MODULE)
  - Moved call to omap_ads7846_init to separate small function
  - Register fixed regulator used for touchscreen only if the driver is
    enabled
 - Changed board name (MT_VENTOUX -> Mt.Ventoux)
