2009-12-14avr32: add support for ATNGW100 mkII boardHans-Christian Egtvedt3-18/+134
This patch adds board support for ATNGW100 mkII. This board is an upgrade of the ATNGW100 where the difference is an additional 256 MB NAND flash device and 128 MB 32-bit SDRAM instead of the 32 MB 16-bit SDRAM on ATNGW100. Tested on ATNGW100 mkII, duh (-: Signed-off-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>

The MRMT1 patch mistakenly reverted commit fe272b5bd13d3522f9d1ed35425f1c7af4d8343f.

2009-07-27favr32: improve touchscreen responseBen Nizette1-0/+4
The ezLCD+101 board (to which an favr-32 is fitted) has a long, unshielded, nasty lead between the touch panel and the ads7843 touch controller. In order to get satisfactory response then, we need to employ every noise-reduction trick in the driver's arsenal. After extensive fiddling I've found some good settings: 1) We keep vref on all the time to dramatically reduce settling times (at the cost of a tiny increase in power consumption). 2) Despite 1 the settling time is still non-zero. 500uS is plenty of time for the signals to settle 3) Despite 1 and 2 there's still a little bit of noise around. By setting a pen recheck delay we make the panel feel less touchy and twitchy. Someone with more time and patience myself might be able to tune this numbers further but these settings are now perfectly acceptable for normal use. Tested on ezLCD+101 though should only improve response on other ezLCD+/ favr-32 boards too.

2009-01-05avr32: Hammerhead board supportAlex Raimondi5-0/+663
The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel. It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing. This patch does include the basic support for the fpga device driver, but not the device driver itself.

2008-10-13avr32: Add support for EVKLCD10X addon boardsHans-Christian Egtvedt4-1/+197
This patch lets the user enable support for EVKLCD100 and EVKLCD101 (refered to by EVKLCD10X). By enabling EVKLCD10X support the LCD controller and AC97 controller platform devices are added. The user can also choose between the EVKLCD100 (QVGA display) and the EVKLCD101 (VGA display), this is added to automagically select the correct panel timing and resolution parameters. Enabling support for EVKLCD10X addon board will cripple the MCI platform device a bit since they share two GPIO lines (detect and write-protect). These two lines are disabled when EVKLCD10X is enabled. The default configurations are based upon ATNGW100, but with added AC97C and LCDC driver. Virtual terminal is also enabled by default for EVKLCD10X boards. Verified on hardware with a NGW100 + EVKLCD100/101.

2008-10-05atmel-mci: Platform code for supporting multiple mmc slotsHaavard Skinnemoen4-11/+38
Add the necessary platform infrastructure to support multiple mmc/sdcard slots all at once through a single controller. Currently, the driver will use the first valid slot it finds and stick with that, but later patches will add support for switching between several slots on the fly. Extend the platform data structure with per-slot information: MMC/SDcard bus width and card detect/write protect pins. This will affect the pin muxing as well as the capabilities announced to the mmc core. Note that board code is now required to supply a mci_platform_data struct to at32_add_device_mci().
