Touch devices have physical buttons too, and these should be
subject to repeat acceleration. That feature was disabled for
the sake of better touch event responsiveness (apparently).
So, re-enable the acceleration feature & add a special case
to exempt BUTTON_TOUCHSCREEN from acceleration.

Based on a patch by Amaury Pouly which was based on a patch from Ryan
Hitchman.
I mainly moved the code for polling into the tuner driver so it can be
reused by other targets. I added the CONFIG parameter for the polling
frequency (in ticks) to save energy. Also, I did some minor cleanups.

All three X1000 native targets turned out to have a very
similar boot configuration and used a nearly identical
makefile. Eliminate this duplication by moving the logic
into the main makefile.

Due to how the old control request API worked, the request
pointer (and the pointed-to contents) passed by the driver
must remain valid for the lifetime of the request.
The buffered copy wasn't used consistently anyway, so it
should be safe to just get rid of it.
(This only affects the old API compatibility layer.)

In the old API, usb_core_transfer_complete() would ignore
any completions on EP0. The legacy control API will also
ignore most completions on EP0, but it only did so after
filling in the completion event.
If the driver submits a spurious completion on EP0, then
this could clobber a previously queued completion event.
Fix this by deciding whether to ignore the completion
*before* modifying the event data.

Appears to return 0 until the axp has (presumably) completed
its first real measurement.
Note about erosq: keep the power_inint() delay large to ensure
nothing breaks in the bootloader for the time being.

The address from the packet needs to be saved before sending
the response -- after the response the request being pointed
to could get overwritten. This used to be done correctly but
I unintentionally broke it when updating the handler to the
new control request API.

Ive seen no ill effects having this disabled on target so
limit it to the sim to stop Address Sanitizer from dumping
on the extra byte read. the bad data is never used AFAICT
since the loop ends

Because usb_core_legacy_control_request() is called by an
interrupt handler the global variables used to track the
current control request at the very least need to be volatile.
It might also be necessary to disable IRQs but I'm not sure
of that.

OST timer fix (7a5130a277) causes a boot failure on some units,

The battery stabilization delay call seems to need to be
about 170 at minimum now, let's do 190 for safety (+20ms).

It turns out the prescaler fields in OST_CTRL are 2 bits wide,
not 3. The programming manual (as usual) is ambiguous and its
diagram shows 2-bit wide fields, but the bit positions in the
text give a 3-bit wide field. Ingenic's Linux code and my own
testing shows that they are, in fact, 2 bits wide.
This caused the OST2 divisor to be 16 instead of 4; the OST1
divisor was correct. This means that all udelay/mdelay calls
took 4x longer than they should've. After this change the OST2
prescaler will be 4, as intended, and udelay/mdelay calls will
wait for the intended duration.

This boosts USB transfer performance a bit, ~10% for reads and
~25% for writes, for large-ish file transfers. Rockbox is still
around 33-50% slower than the OF.

When performing an OUT transfer which is not a multiple of the
max packet size, the last packet of the OUT transfer should be
a short packet. However, there's no guarantee the host sends
the expected amount of data in the final packet.
The DWC2 USB controller handles this case by accepting any size
packet and copying it out to memory. So if the packet is bigger
than expected, it'll overrun the caller's buffer and Bad Things
will happen.
The USB 2.0 spec seems to endorse this behavior. Section 8.5.1
says "an ACK handshake indicates the endpoint has space for a
wMaxPacketSize data payload." So it is possible that other USB
controllers share the DWC2's behavior.
The simplest solution is to force all USB RX buffers to be big
enough to hold the transfer size, rounded up to a multiple of
the max packet size. For example, a transfer of 700 bytes would
require a 1024-byte buffer if the MPS = 512 bytes.

Write -1 to AIC_DR to initialize the "last sample"
to -1 in order to prevent power-on clicks.
It appears necessary to completely fill the FIFO,
otherwise I was able to get a click out of it, however
uncommon it was.
Not only does this prevent a click when first
playing a song after power-on, but it also seems to prevent
any click at all when powering on - previously, a small
click may have been heard when first booting.

Previously it used the last sample, which turns out to be broken.
The AIC appears to send out a random non-zero sample continously
after boot -- probably because the last sample is uninitialized by
the hardware. Disabling playback is supposed to make it send zero
samples irregardless of the LSMP bit according to the docs, but it
doesn't seem to work this way.
- Change eliminates the white noise heard on the M3K after boot.
- Change has no adverse effects on the Q1.
- Leave Eros Q on the old setting since sending zeros exacerbates
clicking due to DAC's automute feature.

According to a forum user, there's an audible click when changing
the volume between -32 and -32.5 dB with some headphones. Fix this
by not (ab)using the DAC digital mixer for volume control.
The mixer only provides an extra -6 dB of hardware volume range,
so the only side effect is that software volume will now kick in
at -32 dB instead of -38 dB.

Upon getting a USB reset, the USB core will update charging
current by calling usb_charging_maxcurrent_change(). On all
current X1000 targets this may cause a hang, since changing
the charge current involves a blocking I2C transaction.
Eg. if the host issues a reset when we're already configured
as part of error recovery, the change from 500 mA -> 100 mA
will cause a hang.

Adjust the battery scale to be a little better. I've set
the 100% (discharge) point to be where the battery sags to
when it is done charging but still plugged in.
Not quite sure how best to set the charge scale, it's just
equal to the discharge scale for now.
