to read/write some register status through the DBI.
The controller support delaying the Link Training by setting

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.

If it is not controlled, when the path is configured after
resume, the clock will be continuously turn on to increase
the clock count.
Therefore, we can count and control the switch of clock
separately according to the current status of playback and
capture, so as to avoid that mclk is accidentally turned off
when playback and capture exist at the same time, causing
the other stream to fail to work.
For example:
- before:
mclk_sai0 2 2 0 11289600 0 0 50000
mclk_sai0_out2io 1 1 0 11289600 0 0 50000
mclk_sai0_to_io 16 16 0 11289600 0 0 50000
- after:
mclk_sai0 2 2 0 11289600 0 0 50000
mclk_sai0_out2io 1 1 0 11289600 0 0 50000
mclk_sai0_to_io 2 2 0 11289600 0 0 50000

On the RK3588 platform, 8K display is an important feature, but it also
increases system power consumption if the product is concerned about
power consumption, 8K can be turned off by default.
Currently, support for 8K display is enabled by default on Linux
platforms, requiring an increase in the aclk of vop to 750MHZ.
Tested on RK3588 EVB, as below:
root@linaro-alip:/# cat /sys/kernel/debug/clk/clk_summary |grep aclk_vop
aclk_vop 1 4 0 750000000 0 0 50000

This is a workaround, an uncertain waveform will be
generated after oneshot ends. It is needed to enable
the dclk scale function to resolve it. It doesn't
matter what the scale factor is, just make sure the
scale function is turned on, for which we set scale
factor to 2.
