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 OMAP driver appears to be correctly calling drm_atomic_helper_shutdown() so we can remove the calls.

As talked about in commit d2aacaf0 ("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 VFP, HBP, and HSA are divided between the available lanes if there is more than one lane. For certain timings and lane configurations, the HFP may not be evenly divisible. If the HFP is rounded down, it ends up being too small which can cause some monitors to not sync properly. In these instances, adjust htotal and hsync to round the HFP up, and recalculate the htotal. This allows 720P-60 to operation on an i.MX8MP with a four-lane configuration.

The P divider should be set based on the min and max values of the fin pll which may vary between different platforms. These ranges are defined per platform, but hard-coded values were used instead which resulted in a smaller range available on the i.MX8M[MNP] than what was possible. As noted by Frieder, there are descripencies between the reference manuals of the Mini, Nano and Plus, so I reached out to my NXP rep and got the following response regarding the varing notes in the documentation. "Yes it is definitely wrong, the one that is part of the NOTE in MIPI_DPHY_M_PLLPMS register table against PMS_P, PMS_M and PMS_S is not correct. I will report this to Doc team, the one customer should be take into account is the Table 13-40 DPHY PLL Parameters and the Note above." With this patch, the clock rates now match the values used in NXP's downstream kernel.

Sam Ravnborg authored
The mode_valid implementation had a call to drm_bridge_chain_mode_fixup() which would be wrong as the mode_valid is not allowed to change anything - only to validate the mode. As the next bridge is often/always a connector the call had no effect anyway. So drop it. From the git history I could see this call was included in the original version of the driver so there was no help there to find out why it was added in the first place. But a lot has changed since the initial driver were added and is seems safe to remove the call now. v4: - Link to v3: https://lore.kernel.org/dri-devel/20220717174454.46616-4-sam@ravnborg.org/ - Rebase, and added acks/rb v3: - Link to v2: https://lore.kernel.org/dri-devel/20211020181901.2114645-6-sam@ravnborg.org/ v2: - Link to v1: https://lore.kernel.org/dri-devel/20210722062246.2512666-6-sam@ravnborg.org/Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Maxime Ripard <mripard@kernel.org> Reviewed-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Acked-by: Chun-Kuang Hu <chunkuang.hu@kernel.org> Cc: Chun-Kuang Hu <chunkuang.hu@kernel.org> Cc: Philipp Zabel <p.zabel@pengutronix.de> Cc: Matthias Brugger <matthias.bgg@gmail.com> Cc: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Cc: linux-mediatek@lists.infradead.org Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Robert Foss <rfoss@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240531-bridge_chain_mode-v1-1-8b49e36c5dd3@ravnborg.org

Identical configurations of planes can lead to different (and wrong) layer -> pipe routing at HW level, depending on the order of atomic plane changes. For example: - Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer is enabled. This is a typical situation at boot. - When a compositor takes over and layer 3 is enabled, sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which will lead to incorrect disabling of pipe 0 and enabling of pipe 1. What happens is that sun8i_ui_layer_enable() function may disable blender pipes even if it is no longer assigned to its layer. To correct this, move the routing setup out of individual plane's atomic_update into crtc's atomic_update, where it can be calculated and updated all at once. Remove the atomic_disable callback because it is no longer needed.

Add support for these pixel format property values: - r5g6b5, RGB565 - b6x2g6x2r6x2, BGR666 BGR666 is presented to userspace as RGB888. The 2 LSB in each color are discarded by the controller. The pixel is sent on the wire using 8 bits per word (little endian) so the controller sees it as BGR. RGB565 is the default if the property is not present.

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.orgSigned-off-by: Noralf Trønnes <noralf@tronnes.org>

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.orgSigned-off-by: Noralf Trønnes <noralf@tronnes.org>

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 MIPI DBI 2.0 specification (2005) lists only two pixel formats for the Type C Interface (SPI) and that is 3-bits/pixel RGB111 with 2 options for bit layout. For Type A and B (parallel) the following formats are listed: RGB332, RGB444, RGB565, RGB666 and RGB888 (some have 2 options for the bit layout). Many MIPI DBI compatible controllers support all interface types on the same chip and often the manufacturers have chosen to provide support for the Type A/B interface pixel formats also on the Type C interface. Some chips provide many pixel formats with optional bit layouts over SPI, but the most common by far are RGB565 and RGB666. So even if the specification doesn't list these formats for the Type C interface, the industry has chosen to include them. 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 bit controls the RGB data latching order transferred from the peripheral’s frame memory to the display device. This means that each supported RGB format also has a BGR variant. Based on this rationale document the following pixel formats describing the bit layout going over the wire: - RGB111 (option 1): x2r1g1b1r1g1b1 (2 pixels per byte) - BGR111 (option 1): x2b1g1r1b1g1r1 (2 pixels per byte) - RGB111 (option 2): x1r1g1b1x1r1g1b1 (2 pixels per byte) - BGR111 (option 2): x1b1g1r1x1b1g1r1 (2 pixels per byte) - RGB565: r5g6b5 (2 bytes) - BGR565: b5g6r5 (2 bytes) - RGB666: r6x2g6x2b6x2 (3 bytes) - BGR666: b6x2g6x2r6x2 (3 bytes) (x: don't care) v2: - Use 'default: r5g6b5' (Rob) Reviewed-by: Rob Herring (Arm) <robh@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240604-panel-mipi-dbi-rgb666-v4-1-d7c2bcb9b78d@tronnes.orgSigned-off-by: Noralf Trønnes <noralf@tronnes.org>

We already have some drm printk functions that need to duplicate a code to get a similar format of the final result, for example: [ ] 0000:00:00.0: [drm:foo] bar [ ] 0000:00:00.0: [drm] foo bar [ ] 0000:00:00.0: [drm] *ERROR* foo Add a generic __drm_dev_vprintk() function that can format the final message like all other existing function do and allows us to keep the formatting code in one place.
