On the RZ/V2H(P) SoC, the DSI PLL dividers need to be as accurate as possible. To ensure compatibility with both RZ/G2L and RZ/V2H(P) SoCs, function pointers are introduced.

In preparation for adding support for the Renesas RZ/V2H(P) SoC, make the "rst" reset control optional in the MIPI DSI driver. The RZ/V2H(P) SoC does not provide this reset line, and attempting to acquire it using the mandatory API causes probe failure. Switching to devm_reset_control_get_optional_exclusive() ensures compatibility with both SoCs that provide this reset line and those that do not, such as RZ/V2H(P).

2025-06-12drm: renesas: rz-du: mipi_dsi: Add OF data supportLad Prabhakar
n preparation for adding support for the Renesas RZ/V2H(P) SoC, this patch introduces a mechanism to pass SoC-specific information via OF data in the DSI driver. This enables the driver to adapt dynamically to various SoC-specific requirements without hardcoding configurations. The MIPI DSI interface on the RZ/V2H(P) SoC is nearly identical to the one on the RZ/G2L SoC. While the LINK registers are shared between the two SoCs, the D-PHY registers differ. Also the VCLK range differs on both these SoCs. To accommodate these differences `struct rzg2l_mipi_dsi_hw_info` is introduced and as now passed as OF data. These changes lay the groundwork for the upcoming RZ/V2H(P) SoC support by allowing SoC-specific data to be passed through OF.

2025-06-12drm: renesas: rz-du: mipi_dsi: Use VCLK for HSFREQ calculationLad Prabhakar
Update the RZ/G2L MIPI DSI driver to calculate HSFREQ using the actual VCLK rate instead of the mode clock. The relationship between HSCLK and VCLK is: vclk * bpp <= hsclk * 8 * lanes Retrieve the VCLK rate using `clk_get_rate(dsi->vclk)`, ensuring that HSFREQ accurately reflects the clock rate set in hardware, leading to better precision in data transmission. Additionally, use `DIV_ROUND_CLOSEST_ULL` for a more precise division when computing `hsfreq`. Also, update unit conversions to use correct scaling factors for better clarity and correctness. Since `clk_get_rate()` returns the clock rate in Hz, update the HSFREQ threshold comparisons to use Hz instead of kHz to ensure correct behavior.

2025-05-23drm: convert many bridge drivers from devm_kzalloc() to ↵Luca Ceresoli
devm_drm_bridge_alloc() API devm_drm_bridge_alloc() is the new API to be used for allocating (and partially initializing) a private driver struct embedding a struct drm_bridge. For many drivers having a simple code flow in the probe function, this commit does a mass conversion automatically with the following semantic patch. The changes have been reviewed manually for correctness as well as to find any false positives. The patch has been applied with the explicit exclusion of bridge/panel.c, handled by a separate patch. After applying the semantic patch, manually fixed these issues: - 4 drivers need ERR_CAST() instead of PTR_ERR() as the function calling devm_drm_bridge_alloc() returns a pointer - re-added empty lines and comments that the script had removed but that should stay @@ type T; identifier C; identifier BR; expression DEV; expression FUNCS; @@ -T *C; +T *C; ...

This patch is based on the commit 73eb5476df72 ("drm: rcar-du: Support panels connected directly to the DPAD outputs"). The RZ DU driver assumes that a bridge is always connected to the DU output. This is valid for the HDMI output, but the DPAD output can be connected directly to a panel, in which case no bridge is available. To support this use case, detect whether the entities connected to the DU DPAD output is encoders or panels based on the number of ports of their DT node, and retrieve the corresponding type of DRM objects. For panels, additionally create panel bridge instances.

2025-04-07drm: renesas: Extend RZ/G2L supported KMS formatsKieran Bingham
The RZ/G2L driver utilises the VSPD to read data from input sources. The rzg2l_du_kms component lists a restricted subset of the capabilities of the VSPD which prevents additional formats from being used for display planes. The supported display plane formats are mapped in rzg2l_du_vsp_formats[]. Extend the rzg2l_du_format_infos[] table with the corresponding mappings between the supported DRM formats and the formats exposed by the VSP in rzg2l_du_vsp_formats, maintaining the same ordering in both tables. The RPF module on VSPD supports various format conversion and send the image data to BRS(Blend ROP Sub Unit) for further processing.

2025-03-20drm/bridge: Add encoder parameter to drm_bridge_funcs.attachMaxime Ripard
The drm_bridge structure contains an encoder pointer that is widely used by bridge drivers. This pattern is largely documented as deprecated in other KMS entities for atomic drivers. However, one of the main use of that pointer is done in attach to just call drm_bridge_attach on the next bridge to add it to the bridge list. While this dereferences the bridge->encoder pointer, it's effectively the same encoder the bridge was being attached to. We can make it more explicit by adding the encoder the bridge is attached to to the list of attach parameters. This also removes the need to dereference bridge->encoder in most drivers.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Based on grepping through the source code, this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time.

Future changes will remove any custom powering off in individual panel drivers so the DRM drivers need to start getting this right.
