Add I2S support for the StarFive JH7110 SoC
Merge series from Xingyu Wu <xingyu.wu@starfivetech.com>:
This patch series adds I2S support for the StarFive JH7110 RISC-V
SoC based on Designware I2S controller. There has three I2S channels
(RX/TX0/TX1) on the JH7110 SoC, one of which is for record(RX) and
two for playback(TX).
The first patch adds support for the StarFive JH7110 SoC in the
Designware I2S bindings.
The second patch adds the ops to get data from platform bus in the
I2S driver.
The third patch adds support for the StarFive JH7110 SoC in
the Designware I2S driver.
The fourth patch fixes the name of I2STX1 pinmux.
The last patch adds device node of I2S RX/TX0/TX1 in JH7110 dts.
This patch series is based on Linux-next(20230818) which is merge
clock, syscon and dma nodes for the StarFive JH7110 SoC.
The series has been tested and works normally on the VisionFive 2
board by plugging an audio expansion board.
