Michael Sevakis fc9695eb47 Improve radio RDS driver and framework 
* 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* Text is no longer updated until a complete group has been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).

app.lds Make INITDATA_ATTR work on everything that has INIT_ATTR enabled for code. 2012-05-01 01:28:50 -04:00
ata-imx31.c Commit to certain names for cache coherency APIs and discard the aliases. 2011-12-17 07:27:24 +00:00
ata-target.h FS#12418 - Merge prototypes from ata-target.h files into new file ata-driver.h. After this change: 2011-12-08 21:23:53 +00:00
avic-imx31.c i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway. 2011-10-14 00:01:41 +00:00
avic-imx31.h i.MX31: Remove long udelay from DVFS interrupt handler 2013-05-11 21:09:01 -04:00
boot.lds Do some things to make -ffunction-sections work better. 2011-12-17 01:43:32 +00:00
ccm-imx31.c Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout. 2010-06-30 02:02:46 +00:00

dvfs_dptc-imx31.h i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00
