After the atomic plane update, the shadow load should be
enabled to make sure its update can take effect on next
frame in any cases. And this enable is better to be done
in CRTC's atomic_flush() which is called after plane's
atomic_update() is called.Besides, the shadow load enable in controller enable is
unnecessary, so remove it.Signed-off-by: Fancy Fang

The LCDIFv3 core driver is responsible to provide
controller registers configuration and create the
platform devices for the child port nodes. And the
platform devices later will attach to the related
DRM/KMS drivers via name match. And the LCDIFv3 is
completely different from the LCDIF controller
which is used on imx8mm and imx8mn platforms.Signed-off-by: Fancy Fang

According to LCDIF specification, the input pixel data
width and the output pixel data width can be different,
and this conversion is done by LCDIF automatically. So
config the output data width according to the requested
bus format from the encoder, instead to be same with the
input pixel data width.Signed-off-by: Fancy Fang

According to the LCDIF specification, the Legacy Mode does not
support cropping function in the horizontal direction, so add
Pigeon Mode which can support this kind of function. And when
enable this mode, the legacy horizontal timings configuration
should use stride value but not the active width, and related
pigeon configuration should use the active width but not the
stride value.Signed-off-by: Fancy Fang

Add an function to get the LCDIF controller supported bus
formats according to the pixel format bpp. And change the
bus format sanity check in the plane's atomic check to see
if the bus format required by the peripheral attached to
LCDIF can be supported by LCDIF.Signed-off-by: Fancy Fang

This patch adds user-configurable CRC region support.
The users may choose a region of interest(ROI) as the CRC source
(i.e., the CRC evaluation window) via the debugfs control node.
The ROI cannot exceed the display region as indicated by
drm_crtc_state->adjusted_mode. The users may write a string in
the fashion of "roi:x1,y1,x2,y2" to the node to specify the ROI
within the display region. The inclusive position at (x1, y1)
indicates the upper left of the region, while the exclusive
position at (x2, y2) indicates the lower right of the region.Signed-off-by: Liu Ying

As DPU fetchunits support ITU601(limited range)/ITU601_FR(full range)
and ITU709(limited range) YUV to RGB color space conversions, we may
add color encoding and color range properties support for planes.
Considering software backward compatibility, the default color encoding
is set to ITU601 with full color range.Signed-off-by: Liu Ying

Without the new blend modes("None", "Pre-multiplied" and "Coverage")
introduced in the below commit, the old userspace assumes alpha in

This patch adds extdst_pixengcfg_syncmode_master() helper support
so that the callers may control if a extdst is master or slave
when it works in sync mode. The bit16 of extdst's PIXENGCFG_STATIC
register controls this and it's a part of sync mode fixup logic.Signed-off-by: Liu Ying

Bit7 of framegen's SECSTATCONFIG register is used to control

This patch adds pixel combiner support in the DPU core driver.

The CRTC background should be full screen instead of partial
screen, because the DRM core is likely to add configurable
background color support in the future. We may cover the full
screen with ConstFrame0/1, upon which builds planes. With this,
it is easier to compute each plane's layer offset vs CRTC start
point and all ConstFrame units can be controlled by CRTC.Signed-off-by: Liu Ying
