drm/msm/dsi: properly handle the case of empty OPP table in dsi_mgr_bridge_mode_valid

2023-01-26T18:51:32+00:00

It was left unnoticed during the review that even if there is no OPP table in device tree, one will be created by a call to the function devm_pm_opp_set_clkname(). This leads to dsi_mgr_bridge_mode_valid() rejecting all modes if DT contains no OPP table for the DSI host. Rework dsi_mgr_bridge_mode_valid() to handle this case by actually checking that the table is populated with frequency entries before returning an error.

drm/msm/dsi: Allow 2 CTRLs on v2.5.0

2023-01-22T20:42:58+00:00

v2.5.0 support was originally added for SC7280, but this hw is also present on SM8350, which has one more DSI host. Bump up the dsi count and fill in the register of the secondary host to allow it to probe. This should not have any adverse effects on SC7280, as the secondary CTRL will only be touched if it's defined, anyway.

drm/msm/dsi: correct byte intf clock rate for 14nm DSI PHY

2023-01-22T20:42:58+00:00

According to the vendor kernel, byte intf clock rate should be a half of the byte clock only when DSI PHY version is above 2.0 (in other words, 10nm PHYs and later) and only if PHY is used in D-PHY mode. Currently MSM DSI code handles only the second part of the clause (C-PHY vs D-PHY), skipping DSI PHY version check, which causes issues on some of 14nm DSI PHY platforms (e.g. qcm2290). Move divisor selection to DSI PHY code, pass selected divisor through shared timings and set byte intf clock rate accordingly.

drm/msm/dsi: implement opp table based check for dsi_mgr_bridge_mode_valid()

2023-01-22T20:42:57+00:00

Currently there is no protection against a user trying to set an unsupported mode on DSI. Implement a check based on the opp table whether the byte clock for the mode can be supported by validating whether an opp table entry exists. For devices which have not added opp table support yet, skip this check otherwise it will break bootup on those devices. changes in v3: - make the comment shorter - handle all errors except ENODEV Closes: https://gitlab.freedesktop.org/drm/msm/-/issues/15 Reported-by: Rob Clark Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/518008/ Link: https://lore.kernel.org/r/20230112001600.12791-2-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov

drm/msm/dsi: add a helper method to compute the dsi byte clk

2023-01-22T20:42:57+00:00

Re-arrange the dsi_calc_pclk method to two helpers, one to compute the DSI byte clk and the other to compute the pclk. This makes the separation of the two clean and also allows clients to compute and use the dsi byte clk separately. changes in v2: - move the assignments to definition lines Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/518005/ Link: https://lore.kernel.org/r/20230112001600.12791-1-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov
