Currently I am working on the Coresight TPIU and STM(sytem trace macrocell ) driver.
The source code for the drivers are also provided at /build/tmp/work-shared/v3msk/kernel-source/hwtracing/core-sight.
However at the /build/tmp/work-shared/v3msk/kernel-source/arh/arm64/boot/dts/renesas path, the r8a77970.dtsi file is missing some device tree sources such as:
Source : STM, STM500, ETM4.0
Link : Funnel, replicator, TMC-ETR
Sinks : TPIU,TMC-ETF, ETB1.1, ETBv1.0
Hence, no kernel logs are being print out from the drivers.
Besides, I have gone through the SoC400 and STM technical reference manual, no information provided such as:
reg : physical base address and length of register set.
clocks, clocks-name, power-domains and so on.
Can I have some guidance or support on this?
