Hi,
This small RFC patchlist is intending to add initial UART4 support
for omap36xx chips.
VERY IMPORTANT:
- This is currently untested. I don't have the HW to test this.
- I don't consider myself an omap-serial expert, so please review
carefully.
Regards,
Sergio
Detailed changeset:
Sergio Aguirre (3):
ARM: OMAP3630: PRCM: Add UART4 control bits
OMAP clock: Add uart4_ick/fck definitions for 3630
omap3: serial: Add uart4 wakeup handling

Tony and I corresponded about this series; we decided that I'll handle this one because most of the changes are clock/PRCM related. Will you get hardware to test this series soon?
