[PATCH 0/3] Add support to configure TPDM MCMB subunit

[Tao Zhang]

Introduction of TPDM MCMB(Multi-lane Continuous Multi Bit) subunit
MCMB (Multi-lane CMB) is a special form of CMB dataset type. 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.

  coresight-tpdm: Add MCMB dataset support
  coresight-tpdm: Add support to select lane
  coresight-tpdm: Add support to enable the lane for MCMB TPDM
