The A23's display pipeline is similar to the A33. Differences include: - Display backend supports larger layers, 8192x8192 instead of 2048x2048 - TCON has DMA input - There is no SAT module packed in the display backend Add compatible strings for the display pipeline and its components. As the MIPI DSI output device is not officially documented, and there are no A23 reference devices to test it, it is not covered by this patch. Signed-off-by:

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

syzbot is hitting a lockdep warning [1] because flush_work() is called without INIT_WORK() after kzalloc() at vkms_atomic_crtc_reset(). Commit 6c234fe3 ("drm/vkms: Implement CRC debugfs API") added INIT_WORK() to only vkms_atomic_crtc_duplicate_state() side. Assuming that lifecycle of crc_work is appropriately managed, fix this problem by adding INIT_WORK() to vkms_atomic_crtc_reset() side.

Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable() to innolux_panel_unprepare(), so they are consistent with innolux_panel_enable() and innolux_panel_prepare(). This also fixes some mode check and irq timeout issue in MTK dsi code. Since some dsi code (e.g. mtk_dsi) have following call trace: 1. drm_panel_disable(), which calls innolux_panel_disable() 2. switch to cmd mode 3. drm_panel_unprepare(), which calls innolux_panel_unprepare() However, mtk_dsi needs to be in cmd mode to be able to send commands (e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()), so we need these functions to be called after the switch to cmd mode happens, i.e. in innolux_panel_unprepare.

Consult the I2C_M_STOP flag to determine whether to set the MOT bit or not. Makes it possible to send multiple messages in one go with stop+start generated between the messages (as opposed nothing or repstart depending on whether thr address/rw changed). Not sure anyone has actual use for this but figured I'd handle it since I started to look at that flag for MST remote i2c xfers. Signed-off-by:

This adds the appropriate device-tree compatible and quirk data for hooking frontend support for the A20. It supports the FIR coefficients ready bit but not the access control bit. It also takes different phase values than the A33 for these coefficients. The compatible is already used in the A10 device-tree and already documented in the device-tree bindings. Signed-off-by:

Planar YUV formats come with 3 distinct planes, which requires configuring the frontend line stride and address registers for the third plane. Our hardware only supports the YUV planes order and in order to support formats with a YVU plane order, a helper is introduced to indicate whether to invert the address of the two chroma planes. Missing definitions for YUV411 and YUV444 input format configuration are also introduced as support is added for these formats. For the input sequence part, no configuration is required for planar YUV formats so zero is returned in that case. Signed-off-by:

Semi-planar YUV formats use two distinct planes, one for luminance and one for chrominance. To add support for them, we need to configure the second line stride and buffer address registers to setup the second YUV plane.

In prevision of adding support for YUV formats, set the YUV to RGB colorspace conversion coefficients if required and don't bypass the CSC engine when converting. The BT601 coefficients from the A33 BSP are copied over from the backend code. Because of module inter-dependency, we can't have the frontend use these coefficients from the backend directly.

Both the backend and the frontend need the BT.601 CSC coefficients for YUV to RGB conversion. Since the backend has a dependency on the frontend (and not the other way round), move the coefficients there so that both can access them without having to duplicate them. Signed-off-by:

Since all the RGB input formats have the same value for the DATA_FMT field of the INPUT_FMT register, we can group them when the format is known to be RGB. Here, we assume that a non-YUV format is RGB, because the hardware does not support any other colorspace than RGB and YUV. Use the DRM format info structure to check whether the format uses a YUV colorspace. Signed-off-by:

The helper returning the input mode needs to know the number of planes for the provided format. Passing the fourcc requires iterating through the format info list in order to return the number of planes. Pass the DRM format info structure directly instead to all helpers related to configuring the input format, since it's available to the caller. Also rename the input format in the caller function to keep things consistent. Signed-off-by:

Display engine drivers often need to distinguish between different types of YUV sub-sampling. This introduces helpers to check for common sub-sampling ratios in their commonly-used denomination from the DRM format info. Signed-off-by:

Paul Kocialkowski authored
It is often useful to check whether the DRM format info retrieved from the DRM framebuffer matches a specific YUV planes disposition. This introduces helpers to quickly check that a provided format info matches a YUV format with a specific disposition, in commonly-used terminology. The intent of providing helpers taking the format info instead of the fourcc alone is to avoid the overhead of iterating through all formats when the whole format info structure is available. As a result, these helpers are very simple so they are made inline. Signed-off-by:
