Subject: [PATCH 10/10] ARM: dts: msm: Add TPDA and TPDM support to DTS for RB5
Add TPDA and TPDM support to DTS for RB5 board. This change is a
sample for validating. After applying this patch, the new TPDM and
TPDA nodes can be observed at the coresight devices path. TPDM and
TPDA hardware can be operated by commands.
List the commands for validating this series patches as below.
echo 1 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
echo 1 > /sys/bus/coresight/devices/tpdm0/enable_source
echo 1 > /sys/bus/coresight/devices/tpdm0/integration_test
echo 2 > /sys/bus/coresight/devices/tpdm0/integration_test
cat /dev/tmc_etf0 > /data/etf-tpdm0.bin
echo 0 > /sys/bus/coresight/devices/tpdm0/enable_source
echo 0 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
echo 1 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
echo 1 > /sys/bus/coresight/devices/tpdm1/enable_source
echo 1 > /sys/bus/coresight/devices/tpdm1/integration_test
echo 2 > /sys/bus/coresight/devices/tpdm1/integration_test
cat /dev/tmc_etf0 > /data/etf-tpdm1.bin
echo 0 > /sys/bus/coresight/devices/tpdm1/enable_source
echo 0 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
echo 1 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
echo 1 > /sys/bus/coresight/devices/tpdm2/enable_source
echo 1 > /sys/bus/coresight/devices/tpdm2/integration_test
echo 2 > /sys/bus/coresight/devices/tpdm2/integration_test
cat /dev/tmc_etf0 > /data/etf-tpdm2.bin
echo 0 > /sys/bus/coresight/devices/tpdm2/enable_source
echo 0 > /sys/bus/coresight/devices/tmc_etf0/enable_sink
If the data from TPDMs can be obtained from the ETF, it means
that the TPDMs verification is successful. At the same time,
since TPDM0, TPDM1 and TPDM2 are all connected to the same
funnel "funnel@...d000" and output via different output ports,
it also means that the following patches verification is
successful.
coresight: add support to enable more coresight paths
coresight: funnel: add support for multiple output ports
