2024-06-07drm/mipi-dbi: Add support for DRM_FORMAT_RGB888Noralf Trønnes
DRM_FORMAT_RGB888 is 24 bits per pixel and it would be natural to send it on the SPI bus using a 24 bits per word transfer. The problem with this is that not all SPI controllers support 24 bpw. Since DRM_FORMAT_RGB888 is stored in memory as little endian and the SPI bus is big endian we use 8 bpw to always get the same pixel format on the bus: b8g8r8. The MIPI DCS specification lists the standard commands that can be sent over the MIPI DBI interface. The set_address_mode (36h) command has one bit in the parameter that controls RGB/BGR order. This means that the controller can be configured to receive the pixel as BGR. RGB888 is rarely supported on these controllers but RGB666 is very common. All datasheets I have seen do at least support the pixel format option where each color is sent as one byte and the 6 MSB's are used. All this put together means that we can send each pixel as b8g8r8 and an RGB666 capable controller sees this as b6x2g6x2r6x2. v4: - s/emulation_format/pixel_format/ (Dmitry) Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240604-panel-mipi-dbi-rgb666-v4-4-d7c2bcb9b78d@tronnes.org Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
2024-06-07drm/mipi-dbi: Make bits per word configurable for pixel transfersNoralf Trønnes
MIPI DCS write/set commands have 8 bit parameters except for the write_memory commands where it depends on the pixel format. drm_mipi_dbi does currently only support RGB565 which is 16-bit and it has to make sure that the pixels enters the SPI bus in big endian format since the MIPI DBI spec doesn't have support for little endian. drm_mipi_dbi is optimized for DBI interface option 3 which means that the 16-bit bytes are swapped by the upper layer if the SPI bus does not support 16 bits per word, signified by the swap_bytes member. In order to support both 16-bit and 24-bit pixel transfers we need a way to tell the DBI command layer the format of the buffer. Add a write_memory_bpw member that the upper layer can use to tell how many bits per word to use for the SPI transfer. v4: - Expand the commit message (Dmitry) Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240604-panel-mipi-dbi-rgb666-v4-3-d7c2bcb9b78d@tronnes.org Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
2024-06-07drm/mipi-dbi: Remove mipi_dbi_machine_little_endian()Noralf Trønnes
mipi_dbi_machine_little_endian() should really have been called mipi_dbi_framebuffer_little_endian() because that's the function it performs. When I added support for these SPI displays I thought that the framebuffers on big endian machines were also big endian, but I have later learned that this is not the case. There's a bit in the fourcc code that controls this: DRM_FORMAT_BIG_ENDIAN. Just remove the function to avoid confusion. We can add big endian support later should the need arise and we have hardware to test on. Instead of just amending the docs, expand it to explain the endianness handling.

The WL-355608-A8 is a 3.5" 640x480@60Hz RGB LCD display from an unknown OEM used in a number of handheld gaming devices made by Anbernic. Limited information is available online however the panel timing values (below) have been obtained from the vendor BSP. The panel appears to integrate a NV3052C LCD driver (or clone). Available devices address it in SPI/RGB mode, with the timing signals generated from the device SoC (Allwinner H700) and passed through. Add a panel definition and display mode to the existing NV3502C driver. It was assumed during bringup that the initialisation sequence was the same as the existing Fascontek FS035VG158 panel, proved working during experimentation, however subsequent dumping of the init sequence with a logic analyser confirms one small change to VCOM_ADJ3 from 0x4a to 0x44, therefore a separate set of registers is also added.

2024-05-29drm/display: Fix HDMI state helper dependencyMaxime Ripard
During the life of the series that introduced the DRM_DISPLAY_HDMI_STATE_HELPER option, we reworked the Kconfig option dependency setup to rely on depends on with commit f6d2dc03fa85 ("drm: Switch DRM_DISPLAY_HDMI_HELPER to depends on") which got reverted later on because it was creating too many issues by commit d7c128cb775e ("Revert "drm: Switch DRM_DISPLAY_HDMI_HELPER to depends on""). However, since the series was out of tree at that time, DRM_DISPLAY_HDMI_STATE_HELPER wasn't properly updated to take the revert into account and is now creating build issues. Let's switch the depends on to a select to fix this.

2024-05-28drm/panel-edp: Add more panels with conservative timingsPin-yen Lin
Same as commit 7c8690d8fc80 ("drm/panel-edp: Add some panels with conservative timings"), the 3 panels added in this patch are used by Mediatek MT8173 Chromebooks and they used to work with the downstream v4.19 kernel without any specified delay. These panel IDs were found from in-field reports, but their datahseets are not available. For BOE 0x0623 and SHP 0x153a, their product names are retrieved from the EDIDs. The EDID of AUO 0x1999 does not contain such information, so list as "Unknown" in this patch. Update these entries with less-conservative timings from other panels of the same vendor.

2024-05-28drm/panel: sony-acx565akm: Don't call disable at removeDouglas Anderson
It's the responsibility of a correctly written DRM modeset driver to call drm_atomic_helper_shutdown() at shutdown time and that should be disabling / unpreparing the panel if needed. Panel drivers shouldn't be calling these functions themselves. A recent effort was made to fix as many DRM modeset drivers as possible [1] [2] [3] and most drivers are fixed now. A grep through mainline for compatible strings used by this driver indicates that it is used by TI OMAP boards. The TI OMAP driver appears to be correctly calling drm_atomic_helper_shutdown() so we can remove the calls.

2024-05-28drm/panel: sony-acx565akm: Don't double-check enabled state in disableDouglas Anderson
As talked about in commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in drm_panel"), we want to remove needless code from panel drivers that was storing and double-checking the prepared/enabled state. Even if someone was relying on the double-check before, that double-check is now in the core and not needed in individual drivers. The acx565akm seems to do some unique stuff with the "enabled" state. Specifically: 1. It seems to detect the enabled state based on how the bootloader left the panel. 2. It uses the enabled state to prevent certain sysfs files from accessing a disabled panel. We'll leave the "enabled" state tracking for this. However, we can at least get rid of the double-check when trying to disable.

Panel drivers shouldn't be calling these functions themselves. A recent effort was made to fix as many DRM modeset drivers as possible [1] [2] [3] and most drivers are fixed now. The compatible strings used by this driver seem to show up across boards using a variety of DRM drivers. It appears that the relevant drivers have been converted, but at least one compatible string doesn't seem to be found in any mainline dts files so we can't be 100% sure. If it is found that the DRM modeset driver hasn't been fixed then this patch could be temporarily reverted until it is.

As talked about in commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in drm_panel"), we want to remove needless code from panel drivers that was storing and double-checking the prepared/enabled state. Even if someone was relying on the double-check before, that double-check is now in the core and not needed in individual drivers. One thing to note for st7703 is that it has a special "allpixelson" debugfs file. When this file is written the driver hacks a disable/unprepare and then a prepare/enable to try to reset the panel. Potentially that might have been relying on the old booleans we removed. It'll still "work" because of the checks in the core but it deserves a comment. This debugfs file didn't appear to be particularly safe to use even before this patch since it would cause a disabled/unprepared panel to become prepared/enabled.
