Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@- ptr->end - ptr->start + 1
+ resource_size(ptr)and some grep and typing.
Mostly uncompiled, no cross-compilers.

This patch fixes the non-compiling AC97C driver for AVR32 architecture by
include mach/hardware.h only for AT91 architecture. The AVR32 architecture does
not supply the hardware.h include file.Signed-off-by: Hans-Christian Egtvedt

This patch add full duplex support on AT91 and AVR.
It was a bug: we needed to check first if there are some chips opened so we
could enable both reception and sending of the data.Signed-off-by: Sedji Gaouaou

This patch add AC97 support for ATMEL AT91, using the AVR32 code.
While AVR is using a DMA, the AT91 chips are using a Peripheral Data
Controller.Signed-off-by: Sedji Gaouaou

zero before disabling the AC97C peripheral.Signed-off-by: Hans-Christian Egtvedt

This patch will enable the AC97C before resetting the external codec,
leaving the AC97C disabled will result in floating I/O lines that can
affect the reset procedure.Signed-off-by: Hans-Christian Egtvedt

This patch will enable interrupts from AC97C and report about error
conditions that occurs.On channel A both overrun and underrun will be enabled depending if
playback and/or capture are enabled. On the control channel the overrun
interrupt is enabled.Signed-off-by: Hans-Christian Egtvedt

This patch will set a proper maximum bytes for the buffer, which is:
channels * bytes per sample * maximum periods * maximum bytes per period.It also sets the minimum periods to 6, a value chosen from testing, with
a minimum of 6 periods the system has good time to fill in new audio
data without skipping.Signed-off-by: Hans-Christian Egtvedt

This patch will take care not to overwrite OCA and ICA registers when
assigning input and output channels. It will also make sure the
registers are at a known state when enabling a channel and clean up
properly in case of an error.Signed-off-by: Hans-Christian Egtvedt

This patch will remove traces of channel B registers, since they are not
used by the AC97C driver. Channel B might be used for other purposes.The driver also adds channel status bits TXEMPTY and OVRUN and a
AC97C_CH_MASK macro to ease clearing a channel settings.Signed-off-by: Hans-Christian Egtvedt

This patch adds ALSA support for the AC97 controller found on Atmel

This patch adds ALSA support for the Audio Bistream DAC found on Atmel
AVR32 devices. The ABDAC is an Atmel IP which might show up on AT91
devices in the future, hence making a generic driver which can be
utilized by AT91 arch if needed.Datasheet describing the ABDAC peripheral is available in the AT32AP7000
datasheet, http://www.atmel.com/dyn/products/datasheets.asp?family_id=682Tested on ATSTK1006 + ATSTK1000 with a class D amplifier stage.
