When bootloader is too intelligent, like on Creative devices, it might leave
some unexpected IRQs sources on, this is problematic when those sources share
the same IRQ line.

The STMP3700 has unreliable vbusvalid irq so we need to use
vdd5gtvddio. Therefore, using the vbusvalid bit produces
inconsistent results between events and detect. Fix that
by making power handle all the usb detect stuff.

These functions are mostly used by the radio drivers and any blocking
call could potentially block the entire UI, which is pretty bad.
Since any request is expected to finish within a few us, having a 10ms
timeout doesn't seem unreasonable.

On targets like stmp3700, resetting the dma channel on "soft" timeout
drives the whole block crazy unless it goes through complete reset.

The driver can now handle HOLD in several ways, including using a GPIO.
Also add a debug routine to read the raw value of the adc.

Many imx233 targets boot in a very low performance mode, typically cpu and
dram at 24MHz. This results in very slow boots and very unstable USB
bootloader mode. Since cpu frequency scaling is disabled in bootloader in
rockbox, always make the frequency scaling code available and boost at boot
time.

This one is a bit strange: our codebase just don't use it if there is both
SD and MMC, so this missing function got unnoticed so far.

The i2c core has some bugs: it locks up when the slave doesn't NAK and
prevent the dma channel from being resetted. Specifically handle this
situation by setting CLR_GOT_A_NAK (workaround) and then reset dma and i2c
block.

Target that have a touchpad/touchscreen should disable it while
being locked (In order to avoid LCD to drain battery power due to
"key locked" constant reporting messages. If they a have a keylock
button this was already handled at driver level. If not (e.g. fuze+),
they will have to implement a switch at driver level that action.c
can operate on softlock.
This patch does the following for any target having a touchpad
or a touchscreen and no HAS_BUTTON_HOLD (ie any softlock target)
1) it implements the code to call button_enable_touch(bool en) in
action.c.
2) button_enable_touch is implemented in button.c and call
either touchpad_enable or touchscreen_enable
3) those two function are implemented respectively in touchscreen.c
and a new touchpad.c file. They provide a generic way to silents touch's
device and call a function at driver level where target specific code
can be implemented if possible/needed (for power saving for instance).
Those function name are touchpad_enable_device and touchscreen_enable_device
4) we implement an empty function at driver level of targets that need it
to have them still being able to compiled.

Instead of going back and forth between TRAN and STBY modes,
stay in TRAN mode all the time, this avoid two commands on each

This allows tells the card the number of blocks that will be
transfered. This is usually faster than continuous read/write.
It is mandatory for MMC and on SD cards, support is probed.

The old max dma transfer size was set to 2^15 because allowing
values up to 2^16 would result in overflow of the transfer count
in many places. This was a problem with the old register headers
because the macros didn't make sure the result is contained in
the bitmask of the field. The new macro do so 2^16 will actually
end up being 0 which means 2^16 for the hardware. This is kind of
hacky but it works and I prefer that this stays a power of two
because setting it to 2^16-1 would be extremely weird.

- take advantage of the new rmi power function implemented to:
1) lower usual power_mode to low_power as it seems to be enough and might save
some battery
2) implement a system that lower that state to very_low_power
after 1 minute of inactivity.
3) implement touchdev_enable(bool) that can be use later to disable the
touchpad when needed
4) improve the debug screen report of the current power state and
changing the power state using volume keys

When using variadic macros there's no need for IF_MD2/IF_MV2 to deal
with function parameters. IF_MD/IF_MV are enough.
Throw in IF_MD_DRV/ID_MV_VOL that return the parameter if MD/MV, or 0
if not.

The old code used get_action which is bad because it belongs to
apps/. Instead rewrite a simple version of get_action, also
rewrite the top level handler. Since the number of screens is
becoming quite high, it now shows a list and the user can start
from any screen. Once in a screen and as long as the user presses
select, it will advance to next screen until it finally returns
to the list on cancellation.

The current code was spreaded over power and powermgmt which made
it behave strangely, especially since there are relationships
between power management and frequency scaling. The new code makes
sure power management is initialised before frequency scaling
starts. It also makes sure to start from a known state, thus
fixing potential issue when the bootloader stops in a trickle
state where DCDC is improperly configured.

Implement the switch function as specified by the specification,
that is wait for the response AND transfer 64 bytes of data. This
fixes some issue when the SD card take a long time to switch. In
particular waiting 100ms (max per spec) will not work if no data
is transfered in some cases.

This adds the application part of alarm wake up. On some targets
like the Fuze+, it will also require a bootloader change to make
sure that the device doesn't power down on alarm wake up (for
example on the Fuze+ the bootloader requires the power button to
be hold sufficiently long, thus preventing alarm wake up to work)
