Mauro, I've applied the pdata patch only into my omap-for-v4.7/legacy branch.
Feel free to merge immutable commit against v4.6-rc1 which is 8453c5cafd32
("ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51") to your tree
also for v4.7 if you decide to apply the ir-rx51 driver changes. Else we need
to wait for v4.7-rc1 :)

Best to do incremental patches on what was posted to avoid confusion.

The pdata changes are in Linux next with omap-for-v4.7/legacy, the driver
changes I have not committed into any upstream going tree. Seems like
Mauro can take it after merging in commit 8453c5cafd32.
