Add coresight components found on Qualcomm SDM845 SoC.
Signed-off-by: Sai Prakash Ranjan <saiprakash.ranjan@codeaurora.org>

This depends on AMBA bus pclk change by Bjorn Andersson [1].
Also depends on patch ("arm64: dts: qcom: sdm845: Increase address
and size cells for soc") [2].

From: Vivek Gautam <vivek.gautam@codeaurora.org>
Enable coresight support by adding device nodes for the
available source, sinks and channel blocks on msm8996.
This also adds coresight cpu debug nodes.

If you want to use the scatter-gather mode, you must add "arm,scatter-gather"
property to the node here.
Have you tested the scatter-gather mode on the chip ? Does that work at all ?
Note: You could try this by setting a buffer_size > 1M for the ETR and use
it as a sink from the sysfs mode.
Cheers
Suzuki

Yes the chip supports scatter-gather mode[1]. But is it required in
dt node since it's an optional property?

If you would like to use the scatter-gather mode, you must specify it
explicitly. We have had some other boards with broken scatter-gather
mode integration which causes mysterious issues when used. So we have
a white-list approach for enabling the scatter-gather mode in the driver.
So, if you have tested to make sure that the mode works fine with a recent
kernel version (v4.19 onwards), you may want to add the property.

Will add scatter-gather and post v3 soon for both SDM845 and MSM8996.

SDM845 has ETMv4.2 and can use the existing etm4x driver.
But the current etm driver checks only for ETMv4.0 and
errors out for other etm4x versions. This patch adds this
missing support to enable SoC's with ETMv4x to use same
driver by checking only the ETM architecture major version
number.
Without this change, we get below error during etm probe:
/ # dmesg | grep etm
[ 6.660093] coresight-etm4x: probe of 7040000.etm failed with error -22
[ 6.666902] coresight-etm4x: probe of 7140000.etm failed with error -22

[ 6.707717] coresight-etm4x: probe of 7740000.etm failed with error -22
With this change, etm probe is successful:
