From 52ea7c0543f8a39da8a6fc17a5ab36b7b58d5431 Mon Sep 17 00:00:00 2001 From: Xingyu Wu Date: Mon, 21 Aug 2023 22:41:49 +0800 Subject: ASoC: dwc: i2s: Add StarFive JH7110 SoC support Add StarFive JH7110(TX0/TX1/RX channels) SoC support in the designware I2S driver and a flag to check if it is on the JH7110 SoC. These channels need to enable clocks, resets and syscon register on the JH7110 SoC. So add init ops in platform data for the JH7110 SoC to do this. Their resets should be deassert before changing the parent of clocks so these are done in the init ops of platform data. The I2S controllers use DMA controller by platform data on the JH7110 and their settings about snd_dmaengine_dai_dma_data() should be added in the dw_configure_dai_by_pd(). And use dmaengine PCM registration if these do not have IRQ on the JH7110 SoC.
