In this patch series, we are adding support for lower end Adreno 5 series GPUs, such as A508, A509 and A512 that we have found in the Qualcomm SDM630, SDM636 and SDM660 SoCs.
On a note, adding support for these three units, also adds 99% of the required "things" for another two GPUs, A505 and A506 but, even if adding them requires literally two lines of code, noone of us has got any SoC equipped with these ones hence we wouldn't be able to test. Even though there is basically no reason for them to not work correctly, kernel side, I chose to avoid adding the two "magic" lines.
Anyway, this patchset also addresses some issues that we've found in the A5XX part of the Adreno driver, regarding a logic mistake in one of the VPC protect values and a forced overwrite of the register named A5XX_PC_DBG_ECO_CNTL, forcing the setting of vtxFifo and primFifo thresholds that was valid only for higher end GPUs.
This patch series has been tested on the following devices: - Sony Xperia XA2 Ultra (SDM630 Nile Discovery) - Sony Xperia 10 (SDM630 Ganges Kirin) - Sony Xperia 10 Plus (SDM636 Ganges Mermaid)
Changes in v3: - Rebased on 5.11-rc3 - Changed emails to reflect new ones - Tested on F(x)Tec Pro1 and Xperia XZ Premium (MSM8998)
Changes in v2: - Define REG_A5XX_UCHE_MODE_CNTL and fix open-coded REG_A5XX_VPC_DBG_ECO_CNTL in the all flat shading optimization disablement commit, as requested by Rob Clark.

The PC_DBG_ECO_CNTL register on the Adreno A5xx family gets programmed to some different values on a per-model basis. At least, this is what we intend to do here;
Unfortunately, though, this register is being overwritten with a static magic number, right after applying the GPU-specific configuration (including the GPU-specific quirks) and that is effectively nullifying the efforts.
Let's remove the redundant and wrong write to the PC_DBG_ECO_CNTL register in order to retain the wanted configuration for the target GPU.

The "main" if branch where we program the other registers for the Adreno 5xx family of GPUs should not contain the PC_DBG_ECO_CNTL register programming because this has logical similarity differences from all the others.
A later commit will show the entire sense of this.

The Adreno 508/509/512 GPUs are stripped versions of the Adreno 5xx found in the mid-end SoCs such as SDM630, SDM636, SDM660 and SDA variants; these SoCs are usually provided with ZAP firmwares, but they have no available GPMU.

Resetting the VBIF before power collapse is done to avoid getting bogus FIFO entries during the suspend sequence or subsequent resume, but this is doable only on Adreno 510 and Adreno 530, as the other units will tendentially lock up. Especially on Adreno 508, the GPU will show lockups and very bad slownesses after processing the first frame.
Avoiding to execute the RBBM SW Reset before suspend will stop the lockup issue from happening on at least Adreno 508/509/512.

The upstream API for some reason uses logbase2 instead of just passing the argument as-is, whereas downstream CAF kernel does the latter.
Hence, a mistake has been made when porting: 4 is the value that's supposed to be passed, but log2(4) = 2. Changing the value to 16 (= 2^4) fixes the issue.

I like keeping it in human readable values because its easier to visually identify how many registers are saved without doing math.
