MCMB subunit has the same number and usage of registers as CMB subunit. Just like the CMB subunit, the MCMB subunit must be configured prior to enablement. This series adds support for TPDM to configure the MCMB subunit. Once this series patches are applied properly, the new tpdm nodes for should be observed at the tpdm path /sys/bus/coresight/devices/tpdm* which supports MCMB subunit. All sysfs files of CMB subunit TPDM are included in MCMB subunit TPDM. On this basis, MCMB subunit TPDM will have new sysfs files to select and enable the lane.
