ipu common: reset ipuv3 correctly

2012-11-06T21:24:11+00:00

This patch checks self-clear sw_ipu_rst bit in
SCR register of SRC controller to be cleared
after setting it to high to reset IPUv3. This
makes sure that IPUv3 finishes sofware reset.
A timeout mechanism is added to stop polling
on the bit status in case the bit could not be
cleared by the hardware automatically within
10 millisecond.

mx5: Use explicit clock gate names

2012-10-15T18:54:10+00:00

Use clock gate definitions having names showing clearly the gated clock instead
of names giving only a register field index.

i.MX6: provide functional names for CCM_CCGR0-CCGR6 bit fields

2012-10-15T18:54:08+00:00

Add meaningful constants for each clock channels and use them for
enabling and disabling i.MX6 clocks.

Includes an update to enable/disable the IPU1 clock in
drivers/video/ipu_common to remove IMX5x register access
when used on i.MX6 as discussed in V1:

ipu_common: Rename MXC_CCM_BASE

2012-07-10T09:35:39+00:00

Rename MXC_CCM_BASE to CCM_BASE_ADDR as this is already defined for MX6.

ipu_common: Let clk_ipu_enable/disable only run on MX51 and MX53

2012-07-10T09:35:39+00:00

The registers accessed inside clk_ipu_enable/disable are not present on MX6,
so make sure they only run on MX51 and MX53.

ipu_common: Only apply the erratum to MX51

2012-07-10T09:35:38+00:00

The following erratum :

"ENGcm08316
IPU: Clarification regarding the bypass mode registers setup for
display and camera interfaces"

only applies to mx51, so restrict its usage for this SoC only.

MX51: Add IPU driver for video support

2010-10-21T22:05:05+00:00

The patch is a porting of the IPU Linux driver
developed by Freescale to have framebuffer
functionalities in u-boot. The port is based on
kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f,
as delivered by Freescale [i.MX BSP].
Most features are dropped from the original driver and
only LCD support is the goal of this porting.
