2024-04-25	ARM: dts: stm32: add LTDC support for STM32MP13x SoC family	Raphael Gallais-Pou
	STM32MP13x SoC family embeds a new version of LTDC (Liquid crystal display - Thin film transistor) Display Controller. It provides a parallel digital RGB (red, green, blue) and signals for horizontal, vertical synchronization, pixel clock and data enable as output to interface directly to a variety of LCD-TFT panels. Main features * 2 input layers blended together to compose the display * Cropping of layers from any input size and location * Multiple input pixel formats: – Predefined ARGB, with 7 formats: ARGB8888, ABGR8888, RGBA8888, BGRA8888, RGB565, BGR565, RGB888packed. – Flexible ARGB, allowing any width and location for A,R,G,B components. – Predefined YUV, with 3 formats: YUV422-1L (FourCC: YUYV, Interleaved), YUV420-2L (FourCC: NV12, semi planar), YUV420-3L (FourCC: Yxx, full planar) with some flexibility on the sequence of the component. * Color look-up table (CLUT) up to 256 colors (256x24 bits) per layer * Color transparency keying * Composition with flexible window position and size versus output display * Blending with flexible layer order and alpha value (per pixel or constant) * Background underlying color * Gamma with non-linear configurable table * Dithering for output with less bits per component (pseudo-random on 2 bits) * Polarity inversion for HSync, VSync, and DataEnable outputs * Output as RGB888 24 bpp or YUV422 16 bpp * Secure layer (using Layer2) capability, with grouped regs and additional interrupt set * Interrupts based on 7 different events * AXI master interface with long efficient bursts (64 or 128 bytes) Signed-off-by: Raphael Gallais-Pou <raphael.gallais-pou@foss.st.com> Signed-off-by: Yannick Fertre <yannick.fertre@foss.st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com>

2023-06-21	ARM: dts: Move .dts files to vendor sub-directories	Rob Herring
	The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.
