Tao Huang c95036feef PM / devfreq: rockchip_dmc: Fix deadlock between dmcfreq and vop on/off ... When change vop status and ddr frequency at the same time, the following deadlock will happen: vop no/off dmcfreq vop_crtc_disable update_devfreq ->mutex_lock(&vop->vop_lock); ->mutex_lock(&pd->pmu->mutex); ->pm_runtime_put(vop->dev); ->mutex_lock(&vop->vop_lock); ->mutex_lock(&pd->pmu->mutex); ... Use new dmcfreq rwsem to decouple vop and pd driver, and get better parallelism.
