[RESEND PATCH v6 16/20] drm/mediatek: Make sure the power-on sequence of LARB and RDMA

2023-09-11 Thread Hsiao Chien Sung
Since LARBs (Local ARBiter) have to be powered on before its users, to ensure the power-on sequence, we created a device link between RDMA and its LARB, and when pm_runtime_get_sync is called in RDMA, system will guarantee the LARB is powered on before the RDMA. Signed-off-by: Hsiao Chien Sung
