!RESET pin
- cirrus,amuteb-eq-bmutec: When given, the Codec's AMUTEB=BMUTEC flag
is enabled.
+ - cirrus,enable-soft-reset:
+ The CS4271 requires its LRCLK and MCLK to be stable before its RESET
+ line is de-asserted. That also means that clocks cannot be changed
+ without putting the chip back into hardware reset, which also requires
+ a complete re-initialization of all registers.
+
+ One (undocumented) workaround is to assert and de-assert the PDN bit
+ in the MODE2 register. This workaround can be enabled with this DT
+ property.
+
+ Note that this is not needed in case the clocks are stable
+ throughout the entire runtime of the codec.
Examples:
