* MLK-10747-2 video: ipu: Enable/disable LDB_DI clock when necessaryLiu Ying2017-04-05-2/+8
| | | | | | | | | This patch adds enable/disable hooks support for ldb_di[0/1] clocks and enables/disables them when necessary. Signed-off-by: Liu Ying <Ying.Liu@freescale.com> (cherry picked from commit 615d4c51679a6c2ee0ed4c5e3922eec76646eef1) (cherry picked from commit 152192507c3bbaba093783d7da32b88327705c63)
* MLK-10747-1 video: ipu: Build ldb_di clock relevant code only for MX6 and MX53Liu Ying2017-04-05-1/+5
| | | | | | | | | The LDB is found in MX6 variants and MX53, so this patch makes the ldb_di clock relevant code be built only for them.

| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

* video: ipu_disp: remove pixclk fixupJeroen Hofstee2014-10-16-25/+6
| | | | | | | | | | | | | | The ipu display insists on having a lower_margin smaller then 2. If this is not the case it will attempt to force it and adjust the pixclk accordingly. This multiplies pixclk in Hz with the width and height, since this is typically a * 10^7 * b * 10^2 * c * 10^2 this will overflow the uint_32 and make things even worse. Since this is a bootloader and the adjustment is neglectible, just force it to two and warn about it. Cc: Stefano Babic <sbabic@denx.de> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

* video: ipu_disp: squash clang warningJeroen Hofstee2014-08-11-1/+1
| | | | | | | | | | | | Since rgb2ycbcr_coeff and friends are declared const, but assigned to a void pointer, clang will warn that the const is implicity casted away. If the pointer is changed to void const * gcc will warn when it is implicitly casted to a const int array. Just add a correctly typed pointer instead to prevent these casts and hence the warnings.

* video: ipu_disp: wait for DP SF end irq when disabling sync BG flowsLiu Ying2014-08-11-19/+8
| | | | | | | | | | | | Instead of waiting for DC triple buffer to be cleared, this patch changes to wait for a relevant DP sync flow end interrupt to come when disabling sync BG flows. In this way, we align the implement to the freescale internal IPUv3 driver. After applying this patch, an uboot hang up issue at the arch_preboot_os() stage, where we disable a relevant ipu display channel, is not observed any more on some MX6DL platforms.

* video: ipu_disp: Fix clock polarity logicFabio Estevam2013-10-30-1/+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 Babic2010-10-22-0/+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>
