we don't directly add all evb board to enable 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 enable rk3588-evb1 sco just for example.
Diff in "rk3588-evb1-lp4-v10.dts" is like this:
+&bt_sco {
+ status = "okay";
+};
+
+&bt_sound {
+ status = "okay";
+};
+
+&i2s2_2ch {
+ status = "okay";
+};
The default pcm/i2s setting is:
Format: PCM, dsp_a, MSB first, short sync, rising edge and delay 1 bclk.
