[PATCH v6 4/5] clk: meson: axg_audio: add S4 support

Sun Jan 25 22:01:45 PST 2026
From: Jiebing Chen <jiebing.chen at amlogic.com>
Add S4 support the axg audio clock controllers, Compared with the
previous version, the selection of the audio's clock and data pad
will be designed in the form of pinmux control. The purpose of doing
this is to distinguish between clock control and pin control selection.
