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:

For the cbcr format, gt2 and gt4 are computed again after src_h has been divided by vsub. As src_h as already been divided by 2 before, introduce cbcr_src_h and cbcr_src_w to keep a copy of those values to be used for cbcr gt2 and gt4 computation.

G121XCE-L01 is a Color Active Matrix Liquid Crystal Display composed of a TFT LCD panel, a driver circuit, and LED backlight system. The screen format is intended to support the 4:3, 1024(H) x 768(V) screen and either 262k/16.7M colors (RGB 6-bits or 8-bits) with LED backlight driver circuit. All input signals are LVDS interface compatible. Documentation [1] and [2] indicate that G121X1-L03 and G121XCE-L01 are effectively identical panels, use the former as RGB 6-bits variant and add the later as RGB 8-bits variant.

The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , add the missing bus_format. Add missing connector type and bus_flags as well. Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is capable of both RGB 18bit/24bit panel, the current configuration uses 18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6. Support for the 24bit mode would require another entry in panel-simple with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which is out of scope of this fix.
