we don't directly enable all evb board to support bt-sco cards
because it may take some i2s/pcm, which may use dma,
but dmas may limit.
so we just prepare this settings, then if any one who want to
support bt-sco, he/she can just add dts in board-level dts.
now, we just enable rk3568-evb1 and rk3566-evb1 just for example.
Diff in "rk3568-evb1-ddr4-v10.dts" is like this:
+&bt_sco {
+ status = "okay";
+};
+
+&bt_sound {
+ status = "okay";
+};
+
+&i2s3_2ch {
+ status = "okay";
+};
The default pcm/i2s setting is:
Format: PCM, dsp_a, MSB first, short sync, rising edge and delay 1 bclk.
