Hello,
Any comments on this patch? It is an unusual use for executable, uncached
memory; but for our purposes, it should be much faster than a full cache
flush, and conceptually cleaner than strongly-ordered executable memory,
which appear to be our only other options in this situation.

Hi ,
I tested the patch on the OMAP 3 EVM. I still find that the hotplug feature
does not work on the OMAP3 EVM. The issue is that if I read the gpio_cd, I am
getting
the correct value on the gpio pin(INSERT = 0, PLUGOUT = 1) but the interrupts
are not generated.

This patch makes it possible to change uart sleep timeout. New sysfs
entry is added (/sys/devices/platform/serial8250.0/sleep_timeout)
Also default timeout is increased to 5 second to make serial console
more usable.
Original patch was written by Tero Kristo some time ago.
This patch allows the UART clocks to be disabled when the OMAP UARTs
are inactive, thus permitting the chip to hit retention in idle.
After the timeout of an activity timer, each UART is allowed to
disable its clocks so the system can enter retention. The activity
timer is (re)activated on any UAR
All GP timers on OMAP2/3 can be wakeup events. The wakeup status is
cleared in the PRCM interrupt handler.

Here is a first pass at updating the core PM code for OMAP.
High-level summary of this series:
- sync up PM core code from linux-omap
- updated PM debug infrastructure
- UART idle and off-mode support for PM development using serial console
Applies on top of the recent OMAP clock framework series
Update OMAP3 EVM board support to support the MMC/SD switches,
when used with the twl4030 based power card.
Also, less usefully, LEDB as a GPIO LED ... it's on the underside
of the board, so it's probably not very useful to most folk. The
