dmaengine: imx-dma: merge old dma-v1.c with imx-dma.c

2012-03-26T06:01:29+00:00

It is mainly a simple merge changing the prefix of some
functions to fit the imx-dma namings.

As there are no users of the old dma-v1.c api we can safely
remove this file.

dmaengine: Add Freescale i.MX SDMA support

2010-10-05T22:49:26+00:00

This patch adds support for the Freescale i.MX SDMA engine.

The SDMA engine is a scatter/gather DMA engine which is implemented
as a seperate coprocessor. SDMA needs its own firmware which is
requested using the standard request_firmware mechanism. The firmware
has different entry points for each peripheral type, so drivers
have to pass the peripheral type to the DMA engine which in turn
picks the correct firmware entry point from a table contained in
the firmware image itself.
The original Freescale code also supports support for transfering
data to the internal SRAM which needs different entry points to
the firmware. Support for this is currently not implemented. Also,
support for the ASRC (asymmetric sample rate converter) is skipped.

I took a very simple approach to implement dmaengine support. Only
a single descriptor is statically assigned to a each channel. This
means that transfers can't be queued up but only a single transfer
is in progress. This simplifies implementation a lot and is sufficient
for the usual device/memory transfers.

ARM: imx: new Kconfig symbol and feature test macro for DMA on mx1 and mx2

2010-06-30T06:59:58+00:00

This should be used instead of hard coding the corresponding platforms.
The feature test macro is needed to support different SOCs in a single
kernel image.  While at it rename dma-mx1-mx2 to dma-v1 as mx25 doesn't
use it and so the mx2 part is wrong and move the header to
arch/arm/mach-imx.

[ARM] pass reboot command line to arch_reset()

2009-03-19T16:20:24+00:00

OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

arm/imx21: Framebuffer support for i.MX21

2009-03-13T09:33:55+00:00

This patch mimicks what Martin wrote on the mailing list:

* move arch/arm/mach-imx/include/mach/imxfb.h into
  arch/arm/mach-mxc/include/mach/imxfb.h
* changes Kconfig so that CONFIG_FB_IMX is selectable
* adds a platform device (copied from some pengutronix
  patches)

[ARM] i.MX: remove LCDC controller register definitions from imx-regs.h

The LCDC controller register definitions are now part of the driver
