Hello,

This patchset adds support for the Freescale/NXP Display Controller Unit (DCU4) for Vybrid which is found on the LS1021A and Vybrid SoC.

Patch series is based on top of latest u-boot master.

First patch in the series renames existing CONFIG_FSL_DCU_FB to CONFIG_VIDEO_FSL_DCU_FB and then converts it to Kconfig. All board defconfigs affected by this patch have been compile tested.

Patch 2-5 introduce incremental changes for supporting DCU on Vybrid.

Patch 6 in the series adds DCU support to Vybrid and has been tested on Toradex Colibri VF61 module.

Will appreciate it if the maintainers or users of LS1021 SoC can test this to check and report regressions if any.

Changes since v1: 1. Rebase of top of latest u-boot master 2. Fix a bug present in v1 patch series which resulted in noisy screen when switching from u-boot to Linux. Patch fixed is second in this series.

v1: https://lists.denx.de/pipermail/u-boot/2017-February/280281.html

Thanks & Regards, Sanchayan.

New subject: [U-Boot] [PATCH v2 2/6] video: fsl_dcu_fb: fix framebuffer to the end of memory

From: Stefan Agner stefan.agner@toradex.com

Fix the framebuffer location to the very end of the available memory. This allows to remove the area from available memory for the kernel, which in turn allows to display the splash screen through the while Linux kernel boot process.

Ideas has been taken from the sunxi display driver, e.g. 20779ec3a5 ("sunxi: video: Dynamically reserve framebuffer memory")

New subject: [U-Boot] [PATCH v2 3/6] video: fsl_dcu_fb: Enable pixel clock after initialization

From: Stefan Agner stefan.agner@toradex.com

When enabling the DCU and pixel clock, the test mode is activated since this is the reset configuration. The test mode immediately shows a red screen on a LCD. A moment later, the DCU gets initialized properly.

This patch enables the pixel clock after initialization of the DCU control register. This avoids this initial flicker on LCD screens.

While at it change the polarity of pixel clock to display samples data on the rising edge.

Users control the graphical content of the panel by manipulating configuration of elements in DCU4 called layers. The number of layers is different for Vybrid and LS102XA SoC's. Update this to reflect for LS102XA accordingly and for use with Vybrid.

That is currently used for DCU_MODE_BLEND_ITER, and it actually overflows the maximum value of BLEND_ITER (for VF610 as well as LS1021a)! I guess since we blindly shift 20 in DCU_MODE_BLEND_ITER(x), we actually write the ADDR register (Two-bit value to be added to pixel red component for dithering), so no real harm there. Still, we should fix it.

I suggest to do the following:

Add a new patch, and fix fsl_dcu_init, just use the default value of 2 pixel blending:

dcu_write32(&regs->mode, DCU_MODE_BLEND_ITER(2) | DCU_MODE_RASTER_EN);

Then we also can avoid adding DCU_TOTAL_LAYER_NUM and just use DCU_LAYER_MAX_NUM for the total layer count...

You should also update ctrldescl in struct dcu_reg to use DCU_TOTAL_LAYER_NUM.

With the above suggestion though, this should be taken care of.
