If, for whatever reason, we're trying process adreno_runtime_resume() at the same time that a6xx_destroy() is running then things can go boom. Specifically adreno_runtime_resume() will eventually call a6xx_pm_resume() and that may try to resume the gmu. Let's grab the GMU lock as we're destroying the GMU. That will solve the race because a6xx_pm_resume() grabs the same lock. That makes the access of `gmu->initialized` in a6xx_gmu_resume() safe. We'll also return an error code in a6xx_gmu_resume() if we see that `gmu->initialized` was false. If this happens we'll bail out of the rest of a6xx_pm_resume(), which is good because the rest of that function is also not good to do if we're racing with a6xx_destroy(). Signed-off-by:

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.

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. Cc: Loic Poulain <loic.poulain@linaro.org> Signed-off-by:

When converting from .txt to .yaml we didn't include descriptions for the existing regulator supplies. - vdd - vdda - vddio Add those descriptions into the yaml now as they were prior to the conversion. In the .txt description we marked these regulators as required, however, that requirement appears to have been in error. Taking the example of sc7180-trogdor-wormdingler.dtsi. The avdd and avee come from GPIO controlled external regulators, not the SoC and in this case there's no need for vddio to power an I/O bus. Similarly the regulators for the LCD are controlled by the panel driver not by the dsi-ctrl driver. It would be possible to connect a different type of panel to the DSI bus here in which case we may or may not want to make use of vdd, vdda or vddio. This is also the case for older chipsets like apq8064, msm8916 etc the vdd* regulators in the dsi-ctrl block are helpers not dependencies. Add the description of vdd, vdda and vddio back in for the existing upstream dts where vdd, vdda or vddio are already declared but, don't declare those regulators required - they are not SoC requirements.

On some SoCs (hello SM6375) vdds-supply is not wired to any smd-rpm or rpmh regulator, but instead powered by the VDD_MX/mx.lvl line, which is voted for in the DSI ctrl node. Signed-off-by:

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:

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:
