This patch will adjust the setup the DMA controller for the AC97
Controller in the at32ap700x machine code. This setup matches the new
ALSA driver for the AC97C.The struct ac97c_platform_data has been moved into its own header file
located in the sound include path.Tested on ATSTK1006 + ATSTK1000.
This patch will setup the AC97 controller properly for the adjusted
machine code. Both EVKLCD10x and Hammerhead board has been updated.Tested on EVKLCD10x, and copied to Hammerhead board.

Merisc is the family name for a range of AVR32-based boards.
The boards are designed to be used in a man-machine interfacing
environment, utilizing a touch-based graphical user interface. They host
a vast range of I/O peripherals as well as a large SDRAM & Flash memory
bank.For more information see: http://www.martinsson.se/merisc

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.Signed-off-by: Alex Raimondi

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.

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().Signed-off-by: Haavard Skinnemoen

The NGW100 board has jumper J15 (near the reset button) which
is unused. This patch exports it through the GPIO sysfs support
(as /sys/class/gpio/gpio62/value) so that it's easily queried
by boot scripts or whatever might want to know if the jumper
has been installed (value = 0) or not (value = 1, "default").Signed-off-by: David Brownell

Minor cleanups for the MMC/SD support on avr32:
- Make at32_add_device_mci() properly initialize "missing"
platform data ... so boards like STK1002 won't try GPIO 0.- Switch over to gpio_is_valid() instead of testing for only
one designated value.- Provide STK1002 platform data for the unlikely case that
switches are set so first Ethernet controller isn't in use.
(That's the only way to get card detect and writeprotect
switch sensing on the STK1000.)And get rid of one "unused variable" warning.

This is a driver for the MMC controller on the AP7000 chips from
Atmel. It should in theory work on AT91 systems too with some
tweaking, but since the DMA interface is quite different, it's not
entirely clear if it's worth merging this with the at91_mci driver.This driver has been around for a while in BSPs and kernel sources
provided by Atmel, but this particular version uses the generic DMA
Engine framework (with the slave extensions) instead of an
avr32-only DMA controller framework.This driver can also use PIO transfers when no DMA channels are
available, and for transfers where using DMA may be difficult or
impractical for some reason (e.g. the DMA setup overhead is usually
not worth it for very short transfers, and badly aligned buffers or
lengths are difficult to handle.)Currently, the driver only support PIO transfers. DMA support has been
split out to a separate patch to hopefully make it easier to review.The driver has been tested using mmc-block and ext3fs on several SD,
SDHC and MMC+ cards. Reads and writes work fine, with read transfer
rates up to 3.5 MiB/s on fast cards with debugging disabled.The driver has also been tested using the mmc_test module on the same
cards. All tests except 7, 9, 15 and 17 succeed. The first two are
unsupported by all the cards I have, so I don't know if the driver
handles this correctly. The last two fail because the hardware flags a
Data CRC Error instead of a Data Timeout error. I'm not sure how to deal
with that.Documentation for this controller can be found in many data sheets from
Atmel, including the AT32AP7000 data sheet which can be found here:http://www.atmel.com/dyn/products/datasheets.asp?family_id=682
