Audio playback/record tested with 44.1Khz sampling rate. Going forward we planned to upstream versa3 clock driver[1] and planned to override the initial values programmed in OTP, so that mclock has 2 clock sources. Based on the sampling rate versa3 clock driver switch the clock source and we can support both 48KHZ and 44.1 KHz as CPU as master. This patch series based on renesas-devel and depend upon [2] [1] https://github.com/renesas-rz/rz_linux-cip/blob/rzg2l-cip41/drivers/clk/clk-versaclock3.c [2]https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=549985 Biju Das (4): arm64: dts: renesas: r9a07g044: Add DMA support to SSI arm64: dts: renesas: rzg2l-smarc: Add WM8978 sound codec arm64: dts: renesas: rzg2l-smarc: Enable audio arm64: dts: renesas: rzg2l-smarc: Add Mic routing arch/arm64/boot/dts/renesas/r9a07g044.dtsi | 11 +++ arch/arm64/boot/dts/renesas/rzg2l-smarc.dtsi | 79 ++++++++++++++++++++ 2 files changed, 90 insertions(+) -- 2.17.1
