- dma-names: Must be "tx", "rx".
+Optional properties:
- atmel,clk-from-rk-pin: bool property.
- When SSC works in slave mode, according to the hardware design, theclock can get from TK pin, and also can get from RK pin. So, addthis parameter to choose where the clock from.- By default the clock is from TK pin, if the clock from RK pin, thisproperty is needed.Examples:
- PDC transfer:
