soc: mediatek: mtk-infracfg: Disable ACP on MT8192

2022-03-01T07:21:28+00:00

MT8192 contains an experimental Accelerator Coherency Port implementation, which does not work correctly but was unintentionally enabled by default. For correct operation of the GPU, we must set a chicken bit disabling ACP on MT8192. Adapted from the following downstream change to the out-of-tree, legacy Mali GPU driver: https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/2781271/5 Note this change is required for both Panfrost and the legacy kernel driver.

soc: mediatek: cmdq: Remove cmdq_pkt_flush()

2021-01-31T11:35:46+00:00

rx_callback is a standard mailbox callback mechanism and could cover the function of proprietary cmdq_task_cb, so it is better to use the standard one instead of the proprietary one. But register rx_callback should before mbox_request_channel(), so remove cmdq_pkt_flush() and let client driver implement its own synchronous flush.
