UART3 is in the PER powerdomain. If PER goes idle/inactive
independently of CORE, for UART3 to wakeup it must have its wakeup
enable bits setup in PM_WKEN_PER. This patch enables these bits.
The reason it works when PER and CORE work together is because when
CORE goes inactive/retention, the IOPAD wakeups are enabled and
trigger UART3 wakeup.
Without this patch, when the UART inactivity timer fires for UART3,
its clocks are disabled and it's unable to wakeup so will be unusable
until PER is awoken by another source.
Another way of testing is by keeping CORE on during suspend but
allowing PER to hit retention
# echo 3 > /debug/pm_debug/core_pwrdm/suspend
then enter suspend
# echo mem > /sys/power/state
Without this patch, UART3 will be unable to wakeup the system.

With the recent changes omap serial ports match the physical
numbering like they should. Fix the kernel CMDLINE accordingly
so console works.

DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?)
machines as long as old dspgateway code were present in the l-o tree. For
several months it is no longer included, breaking support for McBSP1 based
audio on Amstrad Delta, for example.
This patch, derived from the old dspgateway code, corrects the problem for the
board by simply taking the DSP out of reset state, I guess. That way, things
should not break when a new dsp code is added to the tree, and the change can
be reverted then.
If there are any reports on McBSP1 or other DSP public peripherals not working
for other OMAP1 machines (I've not heard of any for now), I can prepare a more
general patch providing an extra include file with a helper function defined.

Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart
and OMAP_TAG_UART. This works for mach-omap2, but causes issues on
mach-omap1 for some boards as the mach-omap1 serial.c was muxing
pins based on the enabled_uart flag for 15xx.
Fix this by muxing pins in board-*.c files for the 15xx boards for
the uart ports that had enabled_uart flag set before the commit
above.
Tested on Amsdtrad Delta only.
Note that in the future we should add support for powering down
the uarts with a timer like mach-omap2/serial.c does. Otherwise
the enabled uarts will be blocking retention-while-idle.

The DMA channel needs to be disabled before resetting the chain.
Also fix clearing of the OMAP_DMA_ACTIVE status in the linked case.

Updating desc for lid keys and resending patch with proper comments:
Define Spitz buttons as GPIO keys in a way compatible with the old driver:
On/Off: As Suspend EV_PWR key
Raw values of lid sensors SWA and SWB: As EV_SW switches
SWA: Display Down
SWB: Lid Closed
Recommended user space decoding:
SWA==0 & SWB==0: lid opened (landscape mode)
SWA==1 & SWB==0: invalid (or mechanic race condition)
SWA==0 & SWB==1: lid closed with display up (portrait mode or mechanic
race condition while closing to display-less mode)
SWA==1 & SWB==1: lid closed with display down (display-less mode)
AK_INT remote trigger is not mapped as input event. Without complete
remote driver and remote pull-up control it has no useful

mxc_iomux_v3_init() is defined in arch/arm/plat-mxc/iomux-v3.c, which is
not linked for i.MX31 and produces an undefined reference error. Fix this
by building the offending code only for i.MX35.

We have to use mxc_gpio_mode() for the card detection pin
instead of mxc_gpio_setup_multiple_pins() because the latter
does a gpio_request() and thus a later gpio_request() fails.

When sending a NMI_VECTOR IPI using the UV_HUB_IPI_INT register,
we need to ensure the delivery mode field of that register has
NMI delivery selected.
This makes those IPIs true NMIs, instead of flat IPIs. It
matters to reboot sequences and KGDB, both of which use NMI
IPIs.

The MCE initialization code explicitly says it doesn't handle
asymmetric configurations where different CPUs support different
numbers of MCE banks, and it prints a big warning in that case.
Therefore, printing the "mce: CPU supports <x> MCE banks"
message into the kernel log for every CPU is pure redundancy
that clutters the log significantly for systems with lots of
CPUs.

A few parts of the uv_hub_info structure are initialized
incorrectly.
- n_val is being loaded with m_val.
- gpa_mask is initialized with a bytes instead of an unsigned long.
- Handle the case where none of the alias registers are used.
Lastly I converted the bau over to using the uv_hub_info->m_val
which is the correct value.
Without this patch, booting a large configuration hits a
problem where the upper bits of the gnode affect the pnode
and the bau will not operate.

Older binutils breaks if ASSERT() is used without a sink
for the output.
For example 2.14.90.0.6 is known to be broken, the link
fails with:
LD .tmp_vmlinux1

Document this quirk in all three files that use it.

The open function got the BKL via the big push down. Replace it by
preempt_enable/disable as this is sufficient for an UP machine.
The ioctl can be unlocked because there is no functionality which
requires serialization. The usage by multiple callers is broken with
and without the BKL due to the local static variable addr.

Presently The SH-4 cache flushing code uses flush_cache_4096() for most
of the real flushing work, which breaks down to a fixed 4096 unroll and
increment. Not only is this sub-optimal for larger page sizes, it's also
uncovered a bug in sh4_flush_dcache_page() when large page sizes are used
and we have no cache aliases -- resulting in only a part of the page's
D-cache lines being written back.
