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.

The pcie supply design is (rk3566 evb2 example)
DC12V
-> VCC12V_PCIE(controlled by GPIO0_C2_H)
-> VCC3V3_PCIE(controlled by GPIO0_C2_H)
-> VCC5V0_SYS
-> VCC3V3_PI6C(controlled by GPIO0_C2_H)
The pci phy driver only want to enable or disable the VCC3V3_PCIE power.
Suggested from pcie owner to ignore the VCC12V_PCIE and VCC3V3_PI6C, so
the dts only need to add regulator node for VCC3V3_PCIE.
Most of time we keep the regulator name same as the hardware design, so
the dts node is
vcc3v3_pcie: gpio-regulator {
compatible = "regulator-fixed";
regulator-name = "vcc3v3_pcie";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
enable-active-high;
gpio = <&gpio0 RK_PB7 GPIO_ACTIVE_HIGH>;
vin-supply = <&dc_12v>;
};
The regulator type is "regulator-fixed" since its voltage always be
3.3v, min and max should be 3300000 make the regulator has a voltage
value.
The regulator can be enabled or disabled by regulator_enable or
regulator_disable function, so make the GPIO0_B7 as "ena_pin" for the
regulator.
The regulator is supplied by DCIN_12V, so add the vin-supply.
Some boards need a delay before enabling trainning for power to be
stable from the measurement.
By measurement, 5ms is enough for power and refclk to be stable.

Should not be zero ahead, otherwise the min voltage is interpreted
as a wrong value by regulator code.

After changing the drive strength, fix the current
delayline.
