[PATCH v2 0/8] TQMa8MPxL DT fixes

[PATCH v2 0/8] TQMa8MPxL DT fixes

[Alexander Stein]

Hi,

this seris includes small fixes for TQMa8MPxL both on MBa8MPxL and
MBa8MP-RAS314. The ethernet IRQ type has been changed to level-low and CEC
pad configuration has been fixed to use open-drain output.
For both boards the HDMI audio output support has been added as well as
the ENET event2 signal on MBa8MPxL, which can be enabled using
/sys/class/ptp/ptp1/period.

Best regards,
Alexander

Changes in v2:
* Collected R-b
* Fixed typos
