dma: apbh: Add special circular mode for LCD

2013-08-09T19:48:34+00:00

Add special function that executes a specially crafted circular
DMA descriptor. The function doesn't wait for the descriptor to
finish the transfer, since the descritor never finishes. This is
useful when operating a SmartLCD through the LCDIF interface, as
the LCDIF does not give us any means to have continuous refresh
of the SmartLCD. Instead, the RUN bit in the LCDIF CTRL register
must be triggered manually. This can be worked around by starting
an DMA transfer which continuously sets the RUN bit. This function
allows starting exactly such transfer.

imx: Move some header files from arch-mxs to imx-common

2013-04-22T08:22:22+00:00

The following headers are moved to a i.MX common location:

- regs-common.h
- regs-apbh.h
- regs-bch.h
- regs-gpmi.h
- dma.h

This way this header can be re-used also by other i.MX platforms.
For example the i.MX6 which will need it for the upcoming NAND
support.

mxs: dma: Fix APBH DMA driver for MX23

2013-01-28T10:43:00+00:00

The MX23 has less channels for the APBH DMA, sligtly different register
layout and some bits in those registers are placed differently. Reflect
this in the driver. This patch fixes MMC/DMA issue on MX23.

MX28: DMA: Prolong the DMA timeout

2012-09-01T12:58:29+00:00

Load from SPI flash can create a long DMA chain, which can take long
time to transfer. Change the DMA timeout to roughly 10s to prevent
such long chains misreporting errors.

mxs: Convert sys_proto.h prefixes to 'mxs'

2012-09-01T12:58:25+00:00

The sys_proto.h functions (except the boot modes) are compatible with
i.MX233 and i.MX28 so we use 'mxs' prefix for its methods.

DMA: Split the APBH DMA init into block and channel init

2012-04-16T12:53:59+00:00

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.

The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.

The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.
