Tony, Please pull the OMAP UART cleanup and conversion to runtime PM. I had to rebase it onto your soc branch due to the serial.c changes there. This includes changes to drivers/tty/serial/omap-serial.c and those changes have Acks from Greg KH and Alan Cox and I got the OK from them to merge this all together via the OMAP tree. Thanks to Govindraj for his persistence with this series. Boot tested on 2420/n810, 4430/Blaze, 4430/Panda Additional PM testing on 3430/n900, 3530/Overo, 3630/Zoom3. NOTE: while normal UART behavior works fine with this series, including suspend/resume, in order for wakeups from runtime PM to work, this series depends on the PRCM IRQ chaining series from Tero and the the new hwmod init state from Rajendra[1]. However, since runtime PM is disabled by default for the UARTs, they will behave normally even without those dependencies. Kevin [1] http://marc.info/?l=linux-omap&m=132187766930901&w=2 The following changes since commit 4390f5b2cb1f568c1d4b3e5bbf57158f6809627a: ARM: OMAP: TI814X: Add cpu type macros and detection support (2011-12-13 10:46:45 -0800) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git for_3.3/uart/runtime-pm Deepak K (1): ARM: OMAP2+: UART: Allow UART parameters to be configured from board file.
