At the moment ATMEL_USART_{RTS,CTS,CLK} have the values
1, 2 and 3 respectively. Given these are used in bitmasks,
trying to turn on the CLK line will in fact turn on the
RTS and CTS lines as well.
Change the value of ATMEL_USART_CLK to 4.

Adds extra parameter to AT32 at32_map_usart(), so as to reserve
RTS/CTS/CLK pins.
All boards under arch/avr32/boards have been updated (trivial change), but
not all have been tested.

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.

This patch will adjust the setup the DMA controller for the Audio
Bistream DAC in the at32ap700x machine code. This setup matches the new
ALSA driver for the ABDAC.
Tested on ATSTK1006 + ATSTK1000.
This patch will setup the needed platform data for the Audio Bistream
DAC used by the Favr-32 board.

This patch adds two defines for setting a pin mask for 18-bit LCD panels
connected to the LCD controller. One mask for primary output and one

This patch corrects the 15-bit LCDC pin mask definitions to select the
five upper lines in each color byte from the LCDC data output. When
reducing the color depth the LCDC will start filling MSB and downwards.
Also only enable 5 bits per color as the define indicates.

at32_reserve_pin now takes an u32 bitmask rather than a single pin.
This allows to reserve multiple pins at once.

Add essential system devices, including GPIO controllers, automatically
at core_initcall time. This ensures that the devices are there when the
PIO driver gets initialized at postcore_initcall, fixing a bug exposed
by commit d6634db8fe "avr32: Use
platform_driver_probe for pio platform driver".

Currently, setting up the portmux is completely one-shot: Once a pin is
muxed, the portmux driver will complain loudly and refuse to do anything
if you try to set up the same pin again.
Sometimes, it may be necessary to change the configuration of a pin
after it has been set up initially. This patch adds a way to undo the
previous configuration, allowing the pin to be reconfigured.

Hardcoded MMIO base addresses are used a few places throughout the

This file includes the appropriate chip-specific header with MMIO, IRQ
