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

Jiebing Chen via B4 Relay
2026-01-26T06:02:37Z

From: Jiebing Chen <jiebing.chen@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.
