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.

Hsin-Yi, Wang authored
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 for hooking frontend support for the A20. Since the hardware is very similar to the A10, it shares the same quirks (which were already introduced). 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:

The COEF_RDY bit isn't found in all the SoCs featuring some variant of the frontend. Add it to our quirks structure. Reviewed-by:

Maxime Ripard authored
The COEF_RDY bit is used to tell the hardware that new FIR filters coefficients have been written to the registers and that the hardware should take them into account starting next frame. Reviewed-by:

The ACCESS_CTRL bit is not found on all the variants of the frontend, so let's introduce a structure that will hold whether or not we need to set it, and associate it with the compatible. This will be extended for further similar quirks later on. Reviewed-by:

Maxime Ripard authored
Unlike what is currently being done, the ACCESS_CTRL bit documentation asks that this bit should be set before modifying any register. The code in the BSP also does this, so make sure we do this as well. Reviewed-by:

This is the final step to indicate to the core that our driver supports framebuffer modifiers. Signed-off-by:
-
Paul Kocialkowski authored
This introduces a list of supported modifiers for the driver, that includes the Allwinner tiled modifier, as well as a format_mod_supported callback. The callback uses both the backend and frontend helpers to indicate per-format modifier support (including for the linear modifier). Signed-off-by:

Paul Kocialkowski authored
This introduces a helper to check whether a frontend input format supports tiling mode. This helper is used when tiling is requested in the frontend format support helper. Only semiplanar and planar YUV formats are supported by the hardware. Signed-off-by:

Paul Kocialkowski authored
This introduces stride and offset configuration for the VPU tiling mode. Stride is calculated differently than it is for linear formats and an offset is calculated, for which new register definitions are introduced. Signed-off-by:

Paul Kocialkowski authored
This introduces the data input mode definitions for the tiled YUV mode, that are used in the input mode helper if tiling is requested. The modifier is passed to the helper from the framebuffer to determine if tiling is requested. Only semiplanar and planar YUV formats are supported for tiling mode. Signed-off-by:

Paul Kocialkowski authored
This introduces specific definitions for vendor Allwinner and its associated tiled format modifier. This modifier is used for the output format of the VPU, that can be imported directly with the display engine hardware supported by the sun4i-drm driver. Signed-off-by:

Paul Kocialkowski authored
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:
-
Paul Kocialkowski authored
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. New definitions are introduced to configure the input format register for the YUV420 and YUV422 semi-planar formats. Signed-off-by:

This introduces support for packed YUV formats with 4:2:2 sampling using the frontend. Definitions are introduced for the data format and pixel sequence input format register values. Signed-off-by:

Paul Kocialkowski authored
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. Signed-off-by:
-
Paul Kocialkowski authored
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:
-
Paul Kocialkowski authored
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:

Paul Kocialkowski authored
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:
-
Paul Kocialkowski authored
Checking for the number of planes is not sufficient to en ensure that the format is a packed YUV422. Use explicit fourcc helpers for the check instead. Signed-off-by:

Paul Kocialkowski authored
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:

The name powerdown-gpios is the standard property name for the functionality covered by the previous pwdn-gpios name. This rename should be safe to do since the linux driver supporting the binding (lvds-encoder.c) never implemented the property, and no dts file names it. At least not upstream. Reviewed-by:
