* video: ipu_disp: Return a negative value on errorFabio Estevam2013-12-041-1/+1

* video: ipu_disp: Fix clock polarity logicFabio Estevam2013-10-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | Currently the HDMI splash screen image quality on mx6solo does not show a very stable image. By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP, we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit. >From FSL BSP [1] we have: if (!sig.clk_pol) di_gen |= DI_GEN_POLARITY_DISP_CLK; Applying the same logic into U-boot fixes the HDMI image stability.

* MX51: Add IPU driver for video supportStefano Babic2010-10-221-0/+1359
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 <sbabic@denx.de>
