ipu common: reset ipuv3 correctly

2012-11-06T21:24:11Z

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. Signed-off-by: Liu Ying

mx5: Use explicit clock gate names

2012-10-15T18:54:10Z

Use clock gate definitions having names showing clearly the gated clock instead of names giving only a register field index. Signed-off-by: Benoît Thébaudeau Cc: Stefano Babic

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

2012-10-15T18:54:08Z

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: http://patchwork.ozlabs.org/patch/185129/ Signed-off-by: Eric Nelson

ipu_common: Do not hardcode the ipu_clk frequency

2012-07-10T09:35:39Z

Do not hardcode the ipu_clk frequency and let the board file pass this value. Signed-off-by: Fabio Estevam

ipu_common: Rename MXC_CCM_BASE

2012-07-10T09:35:39Z

Rename MXC_CCM_BASE to CCM_BASE_ADDR as this is already defined for MX6. Signed-off-by: Fabio Estevam

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

2012-07-10T09:35:39Z

The registers accessed inside clk_ipu_enable/disable are not present on MX6, so make sure they only run on MX51 and MX53. Signed-off-by: Fabio Estevam

ipu_common: Only apply the erratum to MX51

2012-07-10T09:35:38Z

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. Signed-off-by: Fabio Estevam

MX51: Add IPU driver for video support

2010-10-21T22:05:05Z

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. Signed-off-by: Stefano Babic
