@brief I2S clock configuration for standard mode

Fields

sample_rate_hz: u32

< I2S sample rate

clk_src: i32

< Choose clock source, see soc_periph_i2s_clk_src_t for the supported clock sources. selected I2S_CLK_SRC_EXTERNAL (if supports) to enable the external source clock input via MCLK pin,

ext_clk_freq_hz: u32

< External clock source frequency in Hz, only take effect when clk_src = I2S_CLK_SRC_EXTERNAL, otherwise this field will be ignored, Please make sure the frequency input is equal or greater than BCLK, i.e. sample_rate_hz * slot_bits * 2

mclk_multiple: u32

< The multiple of MCLK to the sample rate Default is 256 in the helper macro, it can satisfy most of cases, but please set this field a multiple of 3 (like 384) when using 24-bit data width, otherwise the sample rate might be inaccurate
