* [media] dvb: Get rid of typedev usage for enumsMauro Carvalho Chehab2015-06-091-7/+10
| | | | | | | | | | | | | | | | | The DVB API was originally defined using typedefs. This is against Kernel CodingStyle, and there's no good usage here. While we can't remove its usage on userspace, we can avoid its usage in Kernelspace. So, let's do it. This patch was generated by this shell script: for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done While here, make CodingStyle fixes on the affected lines.

* [media] tc90522: add driver for Toshiba TC90522 quad demodulatorAkihiro Tsukada2014-09-231-0/+839
This patch adds driver for tc90522 demodulator chips. The chip contains 4 demod modules that run in parallel and are independently controllable via separate I2C addresses. Two of the modules are for ISDB-T and the rest for ISDB-S. It is used in earthsoft pt3 cards. Note that this driver does not init the chip, because the initilization sequence / register setting is not disclosed. Thus, the driver assumes that the chips are initilized externally by its parent board driver before fe->ops->init() are called. Earthsoft PT3 PCIe card, for example, contains the init sequence in its private memory and provides a command to trigger the sequence.
