Improve radio RDS driver and framework

2017-02-12T03:19:32+00:00

* Remove unused bits like the radio event and simplify basic
radio interface. It can be more self-contained with rds.h only
required by radio and tuner code.

* Add post-processing to text a-la Silicon Labs AN243. The chip's
error correction can only do so much; additional checks are highly
recommended. Simply testing for two identical messages in a row
is extremely effective and I've never seen corrupted text since
doing that, even with mediocre reception.

Groups segments must arrive in order, not randomly; logic change
only accepts them in order, starting at 0.

Time readout was made a bit better but really we'd need to use
verbose mode and ensure that no errors were seen during receiving
of time and more checks would be need to have a stable PI. The
text is the important bit anyway.

* Time out of stale text.

* Text is no longer updated until a complete group has been
received, as is specified in the standard. Perhaps go back to
scrolling text lines in the radio screen?

* Add proper character conversion to UTF-8. Only the default G0
table for the moment. The other two could be added in.

* Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow
the option for processed RDS data to be pushed to the driver and
still do proper post-processing (only text conversion for now for
the latter).

i.MX31: Restore screen clearing in DVFS/DPTC debug screen

2017-01-30T00:53:49+00:00

Somewhere along the line the screen stopped being cleared prior to
writing new text on each frame, which left visible bits of
previously-displayed text when it changed.

Improve imx31 interrupt code for PMIC and GPIO

2017-01-30T00:07:55+00:00

Fix stuff that was bugging me about the way I did it at first.

While messing around I found RDS code wasn't masking its GPIO
ISR as it should, which might lead to two different interrupts
messing with the static data.

Get rid of stupid _backlight_* function names

2015-01-12T10:09:27+00:00

_remote_backlight_* and _buttonlight_* are cleaned as well

Gigabeat S: Improve headphone thread implementation.

2014-03-06T22:28:26+00:00

Implement scanning as binary tree in array.

Make the ADC calls fewer without compromising read quality.

Declare the thread function as 'noreturn' to save some stack. Reduce
stack size (regardless, % use is now a bit lower).

Add missing kernel.h includes (hopefully all of them).

Get rid of usb_drv_attach() from USB code.

2013-05-15T02:13:38+00:00

'Twas an idiosyncrasy of detecting a host upon bus reset, which is
obsolete.

Set the right variable type for ucallback :)

i.MX31: Remove long udelay from DVFS interrupt handler

2013-05-12T01:09:01+00:00

Split the ISR into two parts and alllow quick return from first half.

Introduces a uevent() API to have a callback happen in a specified
number of microseconds. Right now only one event is supported.
