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.

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.

Because usb_core_legacy_control_request() is called by an

current control request at the very least need to be volatile.
It might also be necessary to disable IRQs but I'm not sure

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

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.
Change-Id: I2b81c2fa6af9809ef1c354d7a08ca8f9893a7690
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.

IMHO the current name is somewhat misleading:
- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
for the non-blocking case. This inconsistent naming can only
promote confusion. (And what would we call a blocking receive?)
- Other hardware abstraction APIs in Rockbox are usually blocking:
storage, LCD, backlight, audio... in other words, blocking is the
default expected behavior, with non-blocking calls being a rarity.

A reasonable default assumption for a user
would be that they can plug their device into
a USB AC adapter and it will charge with as much
current as it reasonably can. With the previous
default, an AC adapter will only do 100mA, basically
a trickle charge.
Make this configurable default per-device, so as not
to break old devices without testing.
Define TARGET_USB_CHARGING_DEFAULT to USB_CHARGING_FORCE
to use the new default.
Tested on both erosQ Native and M3K.

'Bugfix' mono_bitmap_part reads ahead in the buffer,
if the height is <= char bit pixels other memory gets read
found with [Address Sanitizer]
also g#3332 since this is clearly a problem across the code
instead place the check for height < 8 in the lcd_mono_bitmap_part function
second try places the check above the negative y offset

- LCD: 16-bit RGB565
- all buttons, including scrollwheel
- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -
LO volume will only be put to user-defined max volume
if headphones are not present.
- rtc
- Plugins build, tried a couple and they seem OK
- Bootloader, installable to nand via usbboot
What doesn't work:
- Dual Boot
- power on/off has intermittent, low volume audio click
(sometimes it's completely silent, sometimes there's
a click)
- Audio uses 16-bit volume scaling, so clicking/popping
is pretty bad at lower volumes - need 32 bit volume

- no jztool support

- What is the actual purpose of the Stereo Swtich?
- How does the bluetooth module connect?

Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps.

- Some plugins may not be fully adapted to the screen size and could
benefit from further tweaking.
- LCD shows abnormal effects under some circumstances: for example,
after viewing a mostly black screen an afterimage appears briefly
when going back to a brightly-lit screen. Sudden power-off without
proper shutdown of the backlight causes a "dissolving" effect.

Debounce logic now handles both removal and insertion and verifies

This solves the bootloader "file not found" issue on the Shanling Q1.
It seems a false removal event was generated, causing the filesystem
to be automatically unmounted. Probably this is due to some transient
noise at boot. Delays didn't solve the problem, probably because the
bogus hotplug event was queued, and normal mdelay() would simply delay
event delivery.
