This patch series adds support for coresight on SDM845 and MSM8996. * Patch 1 adds device tree nodes for SDM845 coresight components. * Patch 2 adds device tree nodes for MSM8996 coresight components. * Patch 3 enables support for ETMv4.2 and enables SDM845 to make use of same driver(etm4x). * Patch 4 is a trivial removal of duplicate header file. Patch 1 and 3 depends on below AOSS QMP patches by Bjorn: https://patchwork.kernel.org/patch/10749469/ https://patchwork.kernel.org/patch/10749481/ https://patchwork.kernel.org/patch/10749479/ https://patchwork.kernel.org/patch/10749475/ This patch series has been tested on SDM845 MTP and MSM8996 based Dragonboard 820c. 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.
