Subject: [PATCH 3/3] clk: meson: axg-audio: fix g12a tdmout sclk inverter
Fix the tdmout inverter of the g12a and following SoC families.
This inverter is special and needs two bits to be the inverse of each other
for the inverter to operate properly.
Fixes: 075001385c66 ("clk: meson: axg-audio: add g12a support")
