[PATCH 1/2] pinctrl: ingenic: Add X1600 groups for each I2S system clock
From: Olivier Louvignes
Date: Fri Oct 23 2026 - 16:46:53 EST
The X1600 has a system clock (MCLK) pin for each direction: PB22 for
receive, PB26 for transmit. "i2s-sysclk" takes both, which a board that
only plays cannot use when PB22 has another job. Add "i2s-sysclk-rx" and
"i2s-sysclk-tx" for one each.
Used on a HiBy R1, which only plays and has an interrupt input on PB22:
its DAC takes MCLK from "i2s-sysclk-tx".
