drm/meson: Fix an Alpha Primary Plane bug on Meson GXL/GXM SoCs
On the Amlogic GXL & GXM SoCs, a bug occurs on the primary plane when alpha is used where the alpha is not aligned with the pixel content. The workaround Amlogic implemented is to reset the OSD1 plane hardware block each time the plane is (re)enabled, solving the issue. In the reset, we still need to save the content of 2 registers which depends on the status of the plane, in addition to reload the scaler conversion matrix at the same time.

[ 118.292699] Disabling lock debugging due to kernel taint
It seems that when looping through the OSD EOTF LUT maps, we use the
same max iterator for OETF: 20. This is wrong though, since 20*2 is 40,
which means that we'll stop out of bounds on the EOTF maps.
But, this whole thing is already confusing enough to read through as-is,
so let's just replace all of the hardcoded sizes with
OSD_(OETF/EOTF)_LUT_SIZE / 2.

drm/meson: Support Overlay plane for video rendering
The Amlogic Meson GX SoCs support an Overlay plane behind the primary plane for video rendering. This Overlay plane support various YUV layouts : - YUYV - NV12 / NV21 - YUV444 / 422 / 420 / 411 / 410 The scaler supports a wide range of scaling ratios, but for simplicity, plane atomic check limits the scaling from x5 to /5 in vertical and horizontal scaling. The z-order is fixed and always behind the primary plane and cannot be changed. The scaling parameter algorithm was taken from the Amlogic vendor kernel code and rewritten to match the atomic universal plane requirements. The video rendering using this overlay plane support has been tested using the new Kodi DRM-KMS Prime rendering path along the in-review V4L2 Mem2Mem Hardware Video Decoder up to 3840x2160 NV12 frames on various display modes.

drm: Add support for Amlogic Meson Graphic Controller
The Amlogic Meson Display controller is composed of several components : DMC|---------------VPU (Video Processing Unit)----------------|------HHI------| | vd1 _______ _____________ _________________ | | D |-------| |----| | | | | HDMI PLL | D | vd2 | VIU | | Video Post | | Video Encoders |<---|-----VCLK | R |-------| |----| Processing | | | | | | osd2 | | | |---| Enci ----------|----|-----VDAC------| R |-------| CSC |----| Scalers | | Encp ----------|----|----HDMI-TX----| A | osd1 | | | Blenders | | Encl ----------|----|---------------| M |-------|______|----|____________| |________________| | | ___|__________________________________________________________|_______________| VIU: Video Input Unit --------------------- The Video Input Unit is in charge of the pixel scanout from the DDR memory. It fetches the frames addresses, stride and parameters from the "Canvas" memory. This part is also in charge of the CSC (Colorspace Conversion). It can handle 2 OSD Planes and 2 Video Planes. VPP: Video Post Processing -------------------------- The Video Post Processing is in charge of the scaling and blending of the various planes into a single pixel stream. There is a special "pre-blending" used by the video planes with a dedicated scaler and a "post-blending" to merge with the OSD Planes. The OSD planes also have a dedicated scaler for one of the OSD. VENC: Video Encoders -------------------- The VENC is composed of the multiple pixel encoders : - ENCI : Interlace Video encoder for CVBS and Interlace HDMI - ENCP : Progressive Video Encoder for HDMI - ENCL : LCD LVDS Encoder The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock tree and provides the scanout clock to the VPP and VIU. The ENCI is connected to a single VDAC for Composite Output. The ENCI and ENCP are connected to an on-chip HDMI Transceiver. This driver is a DRM/KMS driver using the following DRM components : - GEM-CMA - PRIME-CMA - Atomic Modesetting - FBDev-CMA For the following SoCs : - GXBB Family (S905) - GXL Family (S905X, S905D) - GXM Family (S912) The current driver only supports the CVBS PAL/NTSC output modes, but the CRTC/Planes management should support bigger modes. But Advanced Colorspace Conversion, Scaling and HDMI Modes will be added in a second time. The Device Tree bindings makes use of the endpoints video interface definitions to connect to the optional CVBS and in the future the HDMI Connector nodes. HDMI Support is planned for a next release.
