Subject: [PATCH v2 1/5] ASoC: dt-bindings: snps,designware-i2s: Add StarFive JH7110 SoC support
Add the StarFive JH7110 (TX0/TX1/RX channel) SoC support in the bindings
of Designware I2S controller. The I2S controller needs two reset items
to work properly on the JH7110 SoC. And TX0 channel as master mode needs
5 clock items and TX1/RX channels as slave mode need 9 clock items on
the JH7110 SoC. The RX channel needs System Register Controller property
to enable it and other platforms do not need it.
