Exactly as the subject line says, is it possible to configure the master clock frequency of an I2S peripheral in the device tree? I’m using an nRF5340. I can see that there’s a clock-source property in nordic,nrf-i2s, which I can set
to ‘ACLK’, and then configure the frequency of that clock in the nordic,nrf-clock node, but I’m stumped after this. It seems like there’s no place to set the prescaler value .mck_setup for nrfx_i2s_config_t. Is there any way to control this property as well
from devicetree, or is this all better suited as a kconfig option.
