Subject: [PATCH v1 0/5] Add I2S support for the StarFive JH7110 SoC

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 the ops to get data from platform bus in the
I2S driver.
The second patch adds support for the StarFive JH7110 SoC in
the Designware I2S bindings.
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 which is merge clock,
syscon and dma nodes for the StarFive JH7110 SoC. And these
should be applied after the following patchset:
https://lore.kernel.org/all/20230724055440.100947-1-xingyu.wu@starfivetech.com/

The series has been tested and works normally on the VisionFive 2
board by plugging an audio expansion board.
