The document was sent in [1] and merged to ASoC for-next branch as commit 1afc60e00de3 ("dt-bindings: mediatek: mt8192: add audio afe document"). However, [2] revealed that the commit 1afc60e00de3 breaks dt_binding_check in linux-next due to dt-bindings/clock/mt8192-clk.h doesn't exist. [3] reverted the commit 1afc60e00de3 and merged as commit 7d94ca3c8acd ("ASoC: mt8192: revert add audio afe document"). dt-bindings/clock/mt8192-clk.h now can be found in linux-next per [4], re-adds the document back.
