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.

there is a 1MB free region that is used to load the firmware but we
shouldn't need that till after a USB connection
so here is my 2nd try

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.

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
this was causing glitches on the Q1 and likely other TS targets
since a negative y was added to height it made it < CHAR_BIT setting
stride = 0 even though the bitmap was >= CHAR_BIT high

It's not yet working and because all storage is removable (and the OF

It has only a couple GB of onboard flash storage with no storage
driver in Rockbox. It hasn't seen any meaningful development since
its initial commit, it's not on the build farm, and the bootloader
build is broken by other refactoring.

I feel this is probably unlikely to be called with a NULL pointer
for cachep but being that we are already doing the check why not
guard file_cache_reset as well

Similar to the native port, the hosted port benefits from
adding a -1 dc bias to the PCM data. This prevents almost
all clicking artifacts.

An oversight on my part meant that setting channel balance to
100% L or 100% R would mute both channels - this logic will
prevent that.

A small negative offset seems to silence all
play/pause clicking on the PCM5102A.
Also adding PCM soft muting, and muting the headphone amp
when the headphones are detected as removed. This has been
tested to not cause any unintended side effects on the
line out.
Also confirmed the numerical dB values are (approx.) correct.
