This adds code to send read commands to read a single byte from the display, in order to perform MTP ID look-up of the mounted panel on the s6e63m0 controller. This is needed for proper biasing on the DSI variants. Signed-off-by:

This panel can be accessed using both SPI and DSI. To make it possible to probe and use the device also from a DSI bus, first break out the SPI support to its own file. Since all the panel driver does is write DCS commands to the panel, we pass a DCS write function to probe() from each subdriver. We make the Kconfig entry for SPI mode default so all current users will continue to work. Signed-off-by:

Following functions are only used internally, not by drivers: - devm_drm_dev_init Also, now that we have a very slick and polished way to allocate a drm_device with devm_drm_dev_alloc, update all the docs to reflect the new reality. Mostly this consists of deleting old and misleading hints. Two main ones: - it is no longer required that the drm_device base class is first in the structure. devm_drm_dev_alloc can cope with it being anywhere - obviously embedded now strongly recommends using devm_drm_dev_alloc v2: Fix typos (Noralf) v3: Split out the removal of drm_dev_init, that's blocked on some discussions on how to convert vgem/vkms/i915-selftests.

While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. v2: don't call ttm_bo_unmap_virtual in nouveau_ttm_io_mem_reserve v3: rebased and use both base and offset in the check v4: fix small typos and test the patch v5: rebased and keep the mem.bus init in TTM.

In order to shrink drm_display_mode below the magic two cacheline mark in 64bit we need to shrink it by another 8 bytes. The easiest thing to eliminate is the 'export_head' list head which is only used during the getconnector ioctl to temporarly track which modes on the connector's mode list are to be exposed and which are to remain hidden. We can simply replace the list head with a boolean which we use to tag the modes that are to be exposed. If we make sure to clear the tags after we're done with them we don't even need an extra loop over the modes to reset the tags at the start of the getconnector ioctl. Conveniently we already have a hole for the boolean left behind by the removal of mode->private_flags. The final size of the struct is now 112 bytes on 32bit and 120 bytes on 64bit. Another alternative would be a temp bitmask so we wouldn't have to have anything in the mode struct itself. The main issue is how large of a bitmask do we need? I guess we could allocate it dynamically but that means an extra kcalloc() and an extra loop through the modes to count them first (or grow the bitmask with krealloc() as needed).

For DP MST outputs, the i2c device currently only supports transfers that can be implemented using remote i2c reads. Such transfers must consist of zero or more write transactions followed by one read transaction. DDC/CI commands require standalone write transactions and hence aren't supported. Since each remote i2c write is handled as a separate transfer, remote i2c writes can support transfers consisting of write transactions, where all but the last have I2C_M_STOP set. According to the DDC/CI 1.1 standard, DDC/CI commands only require a single write or read transaction in a transfer, so this is sufficient. For i2c transfers meeting the above criteria, generate and send a remote i2c write message for each transaction. Add the trivial remote i2c write reply parsing support so remote i2c write acks bubble up correctly. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/37Signed-off-by:

This patch avoid the warning in vkms_get_vblank_timestamp when vblanks aren't enabled. When running igt test kms_cursor_crc just after vkms module, the warning raised like below. Initial value of vblank time is zero and hrtimer.node.expires is also zero if vblank aren't enabled before. vkms module isn't real hardware but just virtual hardware module. so vkms can't generate a resonable timestamp when hrtimer is off. it's best to grab the current time.

The VKMS blend function was ignoring the alpha channel and just overwriting vaddr_src with vaddr_dst. This XRGB approach triggers a warning when running the kms_cursor_crc/cursor-alpha-transparent test case. In IGT, cairo_format_argb32 uses premultiplied alpha (according to documentation). Also current DRM assumption is that alpha is premultiplied. Therefore, this patch considers premultiplied alpha blending eq to compose vaddr_src with vaddr_dst. This change removes the following cursor-alpha-transparent warning: "Suspicious CRC: All values are 0." V2: - static for local functions - const for the read-only variable argb_src - replaces variable names - drops unnecessary comment Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Cc: Haneen Mohammed <hamohammed.sa@gmail.com> Signed-off-by:

The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels. Signed-off-by:
