[ Upstream commit ccef4b2703ff5b0de0b1bda30a0de3026d52eb19 ] The header has a function which calls pr_err(). Don't require users of the header to include and include it here.

drm/msm/a6xx: Resolve the meaning of UBWC_MODE

2025-07-05T00:48:40Z

This bit is set iff the UBWC version is 1.0. That notably does not include QCM2290's "no UBWC".

drm/msm: Use the central UBWC config database

2025-07-05T00:48:39Z

As discussed a lot in the past, the UBWC config must be coherent across a number of IP blocks (currently display and GPU, but it also may/will concern camera/video as the drivers evolve). So far, we've been trying to keep the values reasonable in each of the two drivers separately, but it really make sense to do so centrally, especially given certain fields (e.g. HBB) may need to be gathered dynamically. To reduce room for error, move to fetching the config from a central source, so that the data programmed into the hardware is consistent across all multimedia blocks that request it.
