Subject: [PATCH v2 0/8] MDSS reg bus interconnect
Date: Wed, 12 Jul 2023 15:11:37 +0300 [thread overview]
Message-ID: <20230712121145.1994830-1-dmitry.baryshkov@linaro.org> (raw)
Per agreement with Konrad, picked up this patch series.
Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's
another path that needs to be handled to ensure MDSS functions properly,
namely the "reg bus", a.k.a the CPU-MDSS interconnect.
Gating that path may have a variety of effects. from none to otherwise
inexplicable DSI timeouts.
This series tries to address the lack of that.
Changes since v1:
- Dropped the DPU part, the MDSS vote seems to be enough
- Reworked MDSS voting patch. Replaced static bw value with the
per-platform confgurable values.
- Added sm8450 DT patch.
Dmitry Baryshkov (6):
drm/msm/mdss: correct UBWC programming for SM8550
drm/msm/mdss: switch mdss to use devm_of_icc_get()
drm/msm/mdss: inline msm_mdss_icc_request_bw()
drm/msm/mdss: populate missing data
drm/msm/mdss: Handle the reg bus ICC path
arm64: dts: qcom: sm8450: provide MDSS cfg interconnect
Konrad Dybcio (2):
dt-bindings: display/msm: Add reg bus and rotator interconnects
drm/msm/mdss: Rename path references to mdp_path
