[ARM] 4788/1: S3C24XX: Fix paramet to s3c2410_dma_ctrl if S3C2410_DMAF_AUTOSTART used. · 046c9d32

Ben Dooks authored Jan 28, 2008

Fix the channel parameter to s3c2410_dma_ctrl() in s3c2410_dma_enqueue()
if the S3C2410_DMAF_AUTOSTART is set on the channel.

Spotted by Steven Ryu at Samsung.

[ARM] 4784/1: S3C24XX: Fix GPIO restore glitches · 62feee64

Ben Dooks authored Jan 28, 2008

The core resume code may have caused glitches in the GPIO when
restoring the GPIO state due to the order in which the GPIO registers
were being written.

Change the restore process take into account the state of the
GPIOs on resume and the state the system wants to restore them to.

See the code comments in the patch for more details of the process.

[ARM] 4781/1: S3C24XX: DMA suspend and resume support · c58f7a1d

Ben Dooks authored Jan 28, 2008

If an DMA channel was active at suspend, then ensure that
it is correctly reconfigured when the system resumes.

Note, the previous policy was for each driver to handle their
own reconfiguration on resume. The policy has been changed to
make the individual driver's job easier.

[ARM] 4780/1: S3C2412: Allow for seperate DMA channels for TX and RX · c6709e8e

Ben Dooks authored Jan 28, 2008

The current S3C24XX DMA code does not allow for an peripheral
that has one channel for RX and another for TX.

This patch adds a per-cpu dma operation to select the transmit
or receive channel, and adds support to the S3C2412 for the
seperate DMA channels for TX and RX.
