The tc358775 bridge is pin compatible with earlier tc358765 according to the tc358774xbg_datasheet_en_20190118.pdf documentation. Compared to the tc358765, the tc358775 supports a STBY GPIO and higher data rates. The tc358765 has a register bit for video event mode vs video pulse mode. We must set it to video event mode for the LCD output to work, and on the tc358775, this bit no longer exists. Looks like the registers seem to match otherwise based on a quick glance comparing the defines to the earlier Android kernel tc358765 driver. Reviewed-by:

The current code assumes the data-lanes property is configured on the DSI host side instead of the bridge side, and assumes DSI host endpoint 1. Let's standardize on what the other bridge drivers are doing and parse the data-lanes property for the bridge. Only if data-lanes property is not found, let's be nice and also check the DSI host for old dtb in use and warn. And as Dmitry pointed out, the lanes for the host and the bridge may be different because the lanes may be swapped on the host side. Reviewed-by:

The stby pin is optional. It is only needed for power-up and down sequencing. It is not needed, if the power rails cannot by dynamically enabled. Because the GPIO is now optional, remove the error message. Signed-off-by:

The bridge always uses 24bpp internally. Therefore, for jeida-18 mapping we need to discard the lowest two bits for each channel and thus starting with LV_[RGB]2. jeida-24 has the same mapping but uses four lanes instead of three, with the forth pair transmitting the lowest two bits of each channel. Thus, the mapping between jeida-18 and jeida-24 is actually the same, except that one channel is turned off (by selecting the RGB666 format in VPCTRL). While at it, remove the bogus comment about the hardware default because the default is overwritten in any case. Tested with a jeida-18 display (Evervision VGG644804).

The tc358765 is similar to tc358775. The tc358765 just an earlier version of the hardware, and it's pin and register compatible with tc358775 for most part. From the binding point of view the only difference is that the tc358765 does not have stdby-gpios. Reviewed-by:

The device uses a clock lane, and 1 to 4 DSI data lanes. Let's add the data-lanes property starting at 1 similar to what the other bridge bindings are doing. Let's also drop the data-lanes properties in the example for the DSI host controller to avoid confusion. The configuration of the DSI host depends on the controller used and is unrelated to the bridge binding. Reviewed-by:

For a normal operation, the stby GPIO is not needed. The reset pin is required because once the PPI (PHY protocol interface) is started, it can only be stopped by asserting the reset pin. Signed-off-by:

- Add tracking clear page feature. - Driver should enable the DRM_BUDDY_CLEARED flag if it successfully clears the blocks in the free path. On the otherhand, DRM buddy marks each block as cleared. - Track the available cleared pages size - If driver requests cleared memory we prefer cleared memory but fallback to uncleared if we can't find the cleared blocks. when driver requests uncleared memory we try to use uncleared but fallback to cleared memory if necessary. - When a block gets freed we clear it and mark the freed block as cleared, when there are buddies which are cleared as well we can merge them. Otherwise, we prefer to keep the blocks as separated. - Add a function to support defragmentation. v1: - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as cleared. Else, reset the clear flag for each block in the list(Christian) - For merging the 2 cleared blocks compare as below, drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian) - Defragment the memory beginning from min_order till the required memory space is available. v2: (Matthew) - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks operation within drm buddy. - Write a macro block_incompatible() to allocate the required blocks. - Update the xe driver for the drm_buddy_free_list change in arguments. - add a warning if the two blocks are incompatible on defragmentation - call full defragmentation in the fini() function - place a condition to test if min_order is equal to 0 - replace the list with safe_reverse() variant as we might remove the block from the list. v3: - fix Gitlab user reported lockup issue. - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew) - modify to pass the root order instead max_order in fini() function(Matthew) - change bool 1 to true(Matthew) - add check if min_block_size is power of 2(Matthew) - modify the min_block_size datatype to u64(Matthew) v4: - rename the function drm_buddy_defrag with __force_merge. - Include __force_merge directly in drm buddy file and remove the defrag use in amdgpu driver. - Remove list_empty() check(Matthew) - Remove unnecessary space, headers and placement of new variables(Matthew) - Add a unit test case(Matthew) v5: - remove force merge support to actual range allocation and not to bail out when contains && split(Matthew) - add range support to force merge function. v6: - modify the alloc_range() function clear page non merged blocks allocation(Matthew) - correct the list_insert function name(Matthew).

DisplayID spec v1.3 revision history notes do claim that the toplogy block was added in v1.3 so requiring structure v1.2 would seem correct, but there is at least one EDID in edid.tv with a topology block and structure v1.0. And there are also EDIDs with DisplayID structure v1.3 which seems to be totally incorrect as DisplayID spec v1.3 lists structure v1.2 as the only legal value. Unfortunately I couldn't find copies of DisplayID spec v1.0-v1.2 anywhere (even on vesa.org), so I'll have to go on empirical evidence alone. We used to parse the topology block on all v1.x structures until the check for structure v2.0 was added. Let's go back to doing that as the evidence does suggest that there are DisplayIDs in the wild that would miss out on the topology stuff otherwise. Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as it doesn't appear we can really use it for anything. I *think* we could technically skip all the structure version checks as the block tags shouldn't conflict between v2.0 and v1.x. But no harm in having a bit of extra sanity checks I guess. So far I'm not aware of any user reported regressions from overly strict check, but I do know that it broke igt/kms_tiled_display's fake DisplayID as that one gets generated with structure v1.0.

These variables should be u32 instead of u64 because they're only storing u32 values. Also static checkers complain when we do: suspended_slots &= ~upd_ctx.timedout_mask; In this code "suspended_slots" is a u64 and "upd_ctx.timedout_mask". The mask clears out the top 32 bits which would likely be a bug if anything were stored there. Signed-off-by:
