This series concludes my couple-weeks-long suffering of figuring out the ins and outs of the "non-standard" A6xx GPUs which feature no GMU. The GMU functionality is essentially emulated by parting out a "GMU wrapper" region, which is essentially just a register space within the GPU. It's modeled to be as similar to the actual GMU as possible while staying as unnecessary as we can make it - there's no IRQs, communicating with a microcontroller, no RPMh communication etc. etc. I tried to reuse as much code as possible without making a mess where every even line is used for GMU and every odd line is used for GMU wrapper.. This series contains: - plumbing for non-GMU operation, if-ing out GMU calls based on GMU presence - GMU wrapper support - A610 support (w/ speedbin) - A619 support (w/ speedbin) - couple of minor fixes and improvements - VDDCX/VDDGX scaling fix for non-GMU GPUs (concerns more than just A6xx) - Enablement of opp interconnect properties A619_holi works perfectly fine using the already-present A619 support in mesa. A610 needs more work on that front, but can already replay command traces captures on downstream. NOTE: the "drm/msm/a6xx: Add support for A619_holi" patch contains two occurences of 0x18 used in place of a register #define, as it's supposed to be RBBM_GPR0_CNTL, but that will only be present after mesa-side changes are merged and headers are synced from there.
