[PATCH v4 7/7] drm/msm/adreno: Add support for Adreno 510 GPU
From: AngeloGioacchino Del Regno
The Adreno 510 GPU is a stripped version of the Adreno 5xx,
found in low-end SoCs like 8x56 and 8x76, which has 256K of
GMEM, with no GPMU nor ZAP.
Also, since the Adreno 5xx part of this driver seems to be
developed with high-end Adreno GPUs in mind, and since this
is a lower end one, add a comment making clear which GPUs
which support is not implemented yet is not using the GPMU
related hw init code, so that future developers will not go
crazy with that.
By the way, the lower end Adreno GPUs with no GPMU are:
A505/A506/A510 (usually no ZAP firmware)
A508/A509/A512 (usually with ZAP firmware)

[PATCH v4 0/7] DRM/MSM: Add support for MSM8956 and Adreno 510
From: AngeloGioacchino Del Regno This patch series enables support for MSM8956/76 and its Adreno 510 GPU on the current DRM driver. The personal aim is to upstream MSM8956 as much as possible. This code has been tested on two Sony phones featuring the Qualcomm MSM8956 SoC. Changes in v2: - MDP5: Documented tbu and tbu_rt clocks (Jeffrey) - Adreno510: - Lower case hex where required (Jordan) - Direct register writes (Jordan) - Used gpu_rmw() where required (Jordan) - No mentioning of unsupported A5xx (Jordan) - ZAP firmware exclusions not per-model (Rob) Changes in v3: - Rebased onto linux-next 20191015 - Renamed MSM8x56 references to MSM8x76 (the reason is that I am using the 8976/8x76 name for all the other drivers. Also, the 8976 and 8956 chips are equal and the only changing part is the CPU big cores count) - Splitted dt-bindings modifications as per request (Sean) Changes in v4: - Fixed io_start for the secondary dsi phy on family-b AngeloGioacchino Del Regno (7): drm/msm/mdp5: Add optional TBU and TBU_RT clocks dt-bindings: msm/mdp5: Document optional TBU and TBU_RT clocks drm/msm/mdp5: Add configuration for msm8x76 drm/msm/dsi: Add configuration for 28nm PLL on family B dt-bindings: msm/dsi: Add 28nm PLL for family B compatible drm/msm/dsi: Add configuration for 8x76 drm/msm/adreno: Add support for Adreno 510 GPU .../devicetree/bindings/display/msm/dsi.txt | 1 + .../devicetree/bindings/display/msm/mdp5.txt | 2 + drivers/gpu/drm/msm/adreno/a5xx_gpu.c | 73 +++--- drivers/gpu/drm/msm/adreno/a5xx_power.c | 7 ++ drivers/gpu/drm/msm/adreno/adreno_device.c| 15 +++ drivers/gpu/drm/msm/adreno/adreno_gpu.h | 5 + drivers/gpu/drm/msm/disp/mdp5/mdp5_cfg.c | 98 +++ drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 10 ++ drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.h | 2 + drivers/gpu/drm/msm/dsi/dsi_cfg.c | 22 + drivers/gpu/drm/msm/dsi/dsi_cfg.h | 1 + drivers/gpu/drm/msm/dsi/phy/dsi_phy.c | 2 + drivers/gpu/drm/msm/dsi/phy/dsi_phy.h | 1 + drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c| 18 14 files changed, 243 insertions(+), 14 deletions(-) -- 2.21.0 ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

[PATCH v4 1/7] drm/msm/mdp5: Add optional TBU and TBU_RT clocks
From: AngeloGioacchino Del Regno
Some SoCs, like MSM8956/8976 (and APQ variants), do feature these
clocks and we need to enable them in order to get both of the
hw (mdp5/rot) Translation Buffer Units (TBUs) to properly work.

[PATCH v3 0/7] DRM/MSM: Add support for MSM8956 and Adreno 510
From: AngeloGioacchino Del Regno This patch series enables support for MSM8956/76 and its Adreno 510 GPU on the current DRM driver. The personal aim is to upstream MSM8956 as much as possible. This code has been tested on two Sony phones featuring the Qualcomm MSM8956 SoC. Changes in v2: - MDP5: Documented tbu and tbu_rt clocks (Jeffrey) - Adreno510: - Lower case hex where required (Jordan) - Direct register writes (Jordan) - Used gpu_rmw() where required (Jordan) - No mentioning of unsupported A5xx (Jordan) - ZAP firmware exclusions not per-model (Rob) Changes in v3: - Rebased onto linux-next 20191015 - Renamed MSM8x56 references to MSM8x76 (the reason is that I am using the 8976/8x76 name for all the other drivers. Also, the 8976 and 8956 chips are equal and the only changing part is the CPU big cores count) - Splitted dt-bindings modifications as per request (Sean) AngeloGioacchino Del Regno (4): drm/msm/mdp5: Add optional TBU and TBU_RT clocks dt-bindings: msm/mdp5: Document optional TBU and TBU_RT clocks drm/msm/mdp5: Add configuration for msm8x76 drm/msm/dsi: Add configuration for 28nm PLL on family B dt-bindings: msm/dsi: Add 28nm PLL for family B compatible drm/msm/dsi: Add configuration for 8x76 drm/msm/adreno: Add support for Adreno 510 GPU .../devicetree/bindings/display/msm/dsi.txt | 1 + .../devicetree/bindings/display/msm/mdp5.txt | 2 + drivers/gpu/drm/msm/adreno/a5xx_gpu.c | 73 +++--- drivers/gpu/drm/msm/adreno/a5xx_power.c | 7 ++ drivers/gpu/drm/msm/adreno/adreno_device.c| 15 +++ drivers/gpu/drm/msm/adreno/adreno_gpu.h | 5 + drivers/gpu/drm/msm/disp/mdp5/mdp5_cfg.c | 98 +++ drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 10 ++ drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.h | 2 + drivers/gpu/drm/msm/dsi/dsi_cfg.c | 22 + drivers/gpu/drm/msm/dsi/dsi_cfg.h | 1 + drivers/gpu/drm/msm/dsi/phy/dsi_phy.c | 2 + drivers/gpu/drm/msm/dsi/phy/dsi_phy.h | 1 + drivers/gpu/drm/msm/dsi/phy/dsi_phy_28nm.c| 18 14 files changed, 243 insertions(+), 14 deletions(-) -- 2.21.0 ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
[PATCH v3 7/7] drm/msm/adreno: Add support for Adreno 510 GPU
From: AngeloGioacchino Del Regno
The Adreno 510 GPU is a stripped version of the Adreno 5xx,
found in low-end SoCs like 8x56 and 8x76, which has 256K of
GMEM, with no GPMU nor ZAP.
Also, since the Adreno 5xx part of this driver seems to be
developed with high-end Adreno GPUs in mind, and since this
is a lower end one, add a comment making clear which GPUs
which support is not implemented yet is not using the GPMU
related hw init code, so that future developers will not go
crazy with that.
By the way, the lower end Adreno GPUs with no GPMU are:
A505/A506/A510 (usually no ZAP firmware)
A508/A509/A512 (usually with ZAP firmware)

[PATCH v3 6/7] drm/msm/dsi: Add configuration for 8x76
From: AngeloGioacchino Del Regno
MSM8976, MSM8976 and APQ variants have DSI version 3:10040002
(DSI 6G V1.4.2), featuring two DSIs.
They need three clocks (mdp_core, iface, bus), one GDSC and
two vregs, VDDA at 1.2V and VDDIO at 1.8V.

[PATCH 5/5] drm/msm/adreno: Add support for Adreno 510 GPU
From: "Angelo G. Del Regno"
The Adreno 510 GPU is a stripped version of the Adreno 5xx,
found in low-end SoCs like 8x56 and 8x76, which has 256K of
GMEM, with no GPMU nor ZAP.
Also, since the Adreno 5xx part of this driver seems to be
developed with high-end Adreno GPUs in mind, and since this
is a lower end one, add a comment making clear which GPUs
which support is not implemented yet is not using the GPMU
related hw init code, so that future developers will not go
crazy with that.
By the way, the lower end Adreno GPUs with no GPMU are:
A505/A506/A510 (no ZAP firmware)
A508/A509/A512 (with ZAP firmware)

[PATCH v2 5/5] drm/msm/adreno: Add support for Adreno 510 GPU
From: "Angelo G. Del Regno"
The Adreno 510 GPU is a stripped version of the Adreno 5xx,
found in low-end SoCs like 8x56 and 8x76, which has 256K of
GMEM, with no GPMU nor ZAP.
Also, since the Adreno 5xx part of this driver seems to be
developed with high-end Adreno GPUs in mind, and since this
is a lower end one, add a comment making clear which GPUs
which support is not implemented yet is not using the GPMU
related hw init code, so that future developers will not go
crazy with that.
By the way, the lower end Adreno GPUs with no GPMU are:
A505/A506/A510 (usually no ZAP firmware)
A508/A509/A512 (usually with ZAP firmware)
