Now that the PHY ops are separated, sort them topologically, with the common sun8i_hdmi_phy_set_polarity helper at the top. No function contents are changed in this commit. Signed-off-by:

Since the driver already needs to support multiple sets of ops, we can drop the mid-layer used by the A83T and H3 PHYs. They share only a small amount of code; factor this out as sun8i_hdmi_phy_set_polarity. For clarity, this commit keeps the existing function order. Signed-off-by:

The D1 SoC comes with a new custom HDMI PHY, which does not share any registers with the existing custom PHY. So it needs a new set of ops. Instead of providing a flag in the variant structure, provide the ops themselves. Signed-off-by:

Now that the HDMI PHY is using a platform driver, it can use device- managed resources. Use these, as well as the dev_err_probe helper, to simplify the probe function and get rid of the remove function. Signed-off-by:

The struct resource is not used for anything else, so we can simplify the code a bit by using the helper function. Signed-off-by:

While parsing the DT, the anx7625 driver checks for the presence of a panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores the error pointer and the function returns successfully without first cleaning that variable. This is an issue since other functions later check for the presence of a panel bridge by testing the trueness of that variable. In order to ensure proper behavior, zero out pdata->panel_bridge before returning when no panel bridge is found.

This reverts commit fa0e2564. The kernel test robot reported that attempting to build the vesafb driver fails on some architectures, because these don't define a `struct screen_info`. This leads to linking errors, for example on parisc with allyesconfig: hppa-linux-ld: drivers/video/fbdev/vesafb.o: in function `vesafb_probe': >> (.text+0x738): undefined reference to `screen_info' >> hppa-linux-ld: (.text+0x73c): undefined reference to `screen_info' hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init': >> (.init.text+0x28): undefined reference to `screen_info' >> hppa-linux-ld: (.init.text+0x30): undefined reference to `screen_info' hppa-linux-ld: (.init.text+0x78): undefined reference to `screen_info' The goal of commit fa0e2564 ("fbdev: vesafb: Allow to be built if COMPILE_TEST is enabled") was to have more build coverage for the driver but it wrongly assumed that all architectures would define a screen_info.

Add new functions drm_edid_read(), drm_edid_read_ddc(), and drm_edid_read_custom() to replace drm_get_edid() and drm_do_get_edid() for reading the EDID. The transition is expected to happen over a fairly long time. Note that the new drm_edid_read*() functions do not do any of the connector updates anymore. The reading and parsing will be completely separated from each other. Add new functions drm_edid_alloc(), drm_edid_dup(), and drm_edid_free() for allocating and freeing drm_edid containers.

The CTA Data Block Collection is valid only for CTA extension version 3. In versions 1 and 2, it is a reserved block, which we ignore. The DTD start offset (byte 2, or d in CTA-861 spec), which determines the CTA Data Block Collection size, is specified slightly differently for different versions: Version 1: d = offset for the byte following the reserved data block. If no data is provided in the reserved data block, then d=4. If no DTDs are provided, then d=0 Version 2: d = offset for the byte following the reserved data block. If no data is provided in the reserved data block, then d=4. If d=0, then no detailed timing descriptors are provided, and no data is provided in the reserved data block. Version 3: d = offset for the byte following the data block collection. If no data is provided in the data block collection, then d=4. If d=0, then no detailed timing descriptors are provided, and no data is provided in the data block collection. Ever since commit 9e50b9d5 ("drm: edid: Add some bounds checking"), we've interpreted 0 to mean there are no DTDs but it's all Data Blocks. Per the spec, Data Blocks are only valid for version 3, where we should interpret 0 to mean there are no data blocks. Follow the spec (and hope the EDIDs follow it too).

Currently, the memory to the composition frame is being allocated using the kzmalloc. This comes with the limitation of maximum size of one page size(which in the x86_64 is 4Kb and 4MB for default and hugepage respectively). Somes test of igt (e.g. kms_plane@pixel-format) uses more than 4MB when testing some pixel formats like ARGB16161616 and the following error were showing up when running kms_plane@plane-panning-bottom-right*: [drm:vkms_composer_worker [vkms]] *ERROR* Cannot allocate memory for output frame. This problem is addessed by allocating the memory using kvzalloc that circunvents this limitation. V5: Improve the commit message and drop the debugging issues in VKMS TO-DO(Melissa Wen).

Runtime PM doesn't seem to work correctly on this driver. On top of that, commit 8b6864e3 ("drm/v3d/v3d_drv: Remove unused static variable 'v3d_v3d_pm_ops'") hints that it most likely never did as the driver's PM ops were not hooked-up. So, in order to support regular operation with V3D on BCM2711 (Raspberry Pi 4), get rid of the PM code. PM will be reinstated once we figure out the underlying issues. Signed-off-by:

Convert driver to use this new helper to standardize OF "data-lanes" parsing. Reviewed-by:

Marek Vasut authored
The DSI lane count can be accessed via the dsi device pointer, make use of that. The DSI host pointer is only used in sn65dsi83_host_attach(), move the code around so that the host does not have to be cached in the driver private data. This simplifies the code further. No functional change. This has the added bonus that lt9211, tc358767, sn65dsi83 now use very similar *_mipi_dsi_host_attach() which is ripe for deduplication. Signed-off-by:

Add helper function to count and sanitize DT "data-lanes" property and return either error or the data-lanes count. This is useful for both DSI and (e)DP "data-lanes" property. The later version of the function is an extra wrapper which handles the endpoint look up by regs, that's what majority of the drivers duplicate too, but not all of them. Reviewed-by:

Commit 680532c5 ("drm: adv7511: Add support for i2c_new_secondary_device") allows a device tree node to override the default addresses of the secondary i2c devices. This is useful for solving address conflicts on the i2c bus. In adv7511_init_cec_regmap() the new i2c address of cec device is read from device tree and immediately accessed, well before it is written in the proper register to override the default address. This can cause an i2c error during probe and a consequent probe failure. Once the new i2c address is read from the device tree, override the default address before any attempt to access the cec. Tested with adv7533 and stm32mp157f. Signed-off-by:
