[PATCH v3 0/6] Support display on stm32f469-disco board
The series adds support for the Orise Tech OTM8009A display on the stm32f469-disco board. Substantial differences in the drivers for clock management, LTDC and DSI compared to Linux, made it necessary to modify the device tree. These changes were made in stm32f469-disco-uboot.dtsi to avoid altering the Linux device tree. It is therefore desirable, as soon as possible, to add these drivers the functionalities so that they do not require device tree properties that deviate from those present in the Linux version.
Changes in v3: - Add Patrice Chotard's Reviewed-by tag. - Remove RFC tag - Split "[4/5] ARM: dts: stm32: support display on stm32f469-disco board" patch in 2 parts: - DTS ([4/6] ARM: dts: stm32: support MIPI DSI on stm32f469-disco board) - config and LTDC driver update ([5/6] board: stm32f469-disco: add support to display)
Changes in v2: - Add Patrice Chotard's Reviewed-by tag to patches 1, 2 and 3 of the series. - Fix frame buffer allocation for stm32f469 discovery board.

As described in [1], the "clocks" property contains "a phandle to the clock device node, an index selecting between gated clocks (0) and other clocks (1), and an index specifying the clock to use." The current version of the clock driver, unlike the kernel, is currently able to properly handle nodes with "clocks" properties with an index set to 0.
This patch is preparatory for future developments that require the use of the LTDC clock.

Unlike Linux, the DSI driver requires the LTDC clock to be properly probed. Hence, the changes made to the DSI node.

Add support to Orise Tech OTM8009A display on stm32f469-disco board.
It was necessary to retrieve the framebuffer address from the device tree because the address returned by the video-uclass driver pointed to a memory area that was not usable.

Changes in v3: - Replace SDRAM_SIZE constant with global data gd->ram_size.
Changes in v2: - Add DRAM_SIZE macro. - Fix frame buffer allocation function so that it is backward compatible with boards other than the one it was introduced for (i. e. stm32f469-disco). Tested on stm32f469-disco and stm32mp157f-dk2 boards.
