Subject: [PATCH] ASoC: fsl_sai: Correct the clock source for mclk0
Date: Thu, 19 Nov 2020 10:29:16 +0800 [thread overview]
Message-ID: <1605752956-17397-1-git-send-email-shengjiu.wang@nxp.com> (raw)
On VF610, mclk0 = bus_clk;
On i.MX6SX/6UL/6ULL/7D, mclk0 = mclk1;
On i.MX7ULP, mclk0 = bus_clk;
On i.MX8QM/8QXP, mclk0 = bus_clk;
On i.MX8MQ/8MN/8MM/8MP, mclk0 = bus_clk;
So add variable mclk0_mclk1_match in fsl_sai_soc_data to
distinguish these platforms.
