The STMP3600 cannot lock some usb bits so there is only a single
status in POWER_STS. Also stmp3600 has no clock bypass and frac
div.

This driver does debouncing and best lradc usage and only requires
a sorted table of values to work, this factoring code as much as
possible.

The driver is current unused and very minimal. It can used on
targets which have an accessible UART port and it will be used on
some creative targets as backlight control.

Although everything is implemented, recording still doesn't work,
dma is stuck. Add code for reference until this get a proper fix.

The old driver didn't behave nicely because it waiting for
stability which could never arrive on some gestures. The new one
uses a fixed delay and averaging.

Document various register macros (autogenerated). Fix memory map
for stmp3700, make framebuffer size configurable and cache aligned
and fix the PHYSICAL_ADDR macro.

The lcd data line were not setup as input anymore, making register
reading plain broken and probably lead to bad lcd detection.

Power management is somewhat different on stmp3700 which doesn't
have the 4.2V rail and completely different on stmp3600 which has
several DCDC. Currently only handle imx233.

Using the ssp macros, we can easily handle the stmp3600 which
has a single ssp block. Take care of all the nasty differences
between targets like bus width

Currently don't do anything on stmp3600 because emi is completely
different. On stmp3700 it is unsure how the pll lock is handled
and this will need more testing.

Add finer granularity to start command: now commands can be
prepared, schedule and semaphore increased independently.

Factorise pin setup, rewrite PIO code, add support for lcdif irq,
handle all the various differences between the stmps, drop yuv
blitting code since it already exists in the common lcd drivers.

The lradc architecture of the stmp3600 is rather different:
only channels 6 and 7 have configurable source and we need to
take care when allocating channels so that we can actually
measure the right channel! Delegate die temperature sensing to
the power block on stmp3600.
Change-Id: I0860eb4ea98240facc3d4a19d61684eca5f630cc
There are many small differences between them. In particular
some regulators are not available on stmp3600. Also the vbusvalid
detect method is not available as an irq on stmp3600 and seems
broken on stmp3700. Finally die temperature is handled by the
power block on stmp3600.

Under some circumstance (timeout), the dma interrupt is not fired
and only the error one is. This can happen with some picky SD
cards and with the current code it causes a 1 second timeout.
This code properly catches the error interrupt to stop as soon
as possible.

The current pwm interface is too low-level. Introduce a higher
level setup function which directly computes the parameters from
the required frequency.

The clkctrl functions were becoming a mess. Normalise the names,
get rid of the xtal derived as special case and use the same
interface.

A number of pins on the imx233 are standard and manually calling
functions to acquire, set function/drive/output is painful. This
will become unmanageable when we will add support for the other
stmp chips.
Introduce the concept of virtual pin which is a way to completely
describe a virtual pin (virtual because pins are muxed).

The current pinctrl functions were a mess. Normalise the functions
names to make them shorter and clearer.

The code assumes that gustable[] has 128 entries, while it
only had 120. Since the entries follow a simple pattern (they
seem to be note frequencies, so each entry is the previous one
multiplied by the 2^(1/12)), expanding the table is the simple
fix.
