This patch series adds support for coresight on SDM845, MSM8998, and MSM8996.
* Patch 1 adds device tree nodes for SDM845 coresight components.
* Patch 2 adds device tree nodes for MSM8998 coresight components.
* Patch 3 adds device tree nodes for MSM8996 coresight components.
* Patch 4 enables support for ETMv4.2 and enables SDM845 to make
use of same driver(etm4x).
* Patch 5 adds ETM PIDs for SDM845 and MSM8996.
* Patch 6 adds UCI table for coresight CPU debug module.

Patch 5 and 6 depends on UCI support by Mike Leach:
* https://lore.kernel.org/lkml/20190130234051.2294-1-mike.leach@xxxxxxxxxx/
This patch series has been tested on SDM845 MTP and MSM8996
based Dragonboard 820c and MSM8998 MTP.
v6:
* Update the UCI table with the new macro introduced by
Mike.
* Rebase on top of coresight-next and provide a tree with
all the dependent patches applied.
v5:
* Added coresight support for MSM8998.
* Added ETM PIDs for SDM845 and MSM8996 as suggested
by Suzuki.
* Added UCI table for Coresight CPU debug module.
v4:
* Mask out the minor version as suggested by Mathieu.
* Added the dependent patch description in patch 1.
v3:
* Added arm,scatter-gather property as suggested by Suzuki.
v2:
* Added coresight support for msm8996 based on Vivek's patch.
Cleaned up and added coresight cpu debug nodes for msm8996.
* Merged coresight dtsi file into sdm845.dtsi as suggested by Bjorn
* Addressed Mathieu's feedback about masking the minor version in
etm4_arch_supported() and added a comment for reason to bypass
the AMBA bus discovery method.
