* [media] it913x: add chip device ids for bindingAntti Palosaari2017-01-311-1/+10
| | | | | | | | Driver supports 2 different device versions, AX and BX. Use device IDs to pass chip version information to driver. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* [media] it913x: change driver model from i2c to platformAntti Palosaari2017-01-311-53/+36Star
| | | | | | | | | | That tuner is integrated to demodulator and communicates via demodulators address space. We cannot register both demodulator and tuner having same address to same I2C bus, so better to change it platform driver in order to implement I2C adapter correctly.

* [media] media: Drop FSF's postal address from the source code filesSakari Ailus2017-01-271-4/+0Star
| | | | | | | | | | | | | | | | | | | | | Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated.

* [media] tuners: Drop owner assignment from i2c_driverKrzysztof Kozlowski2015-08-111-1/+0Star

* [media] it913x: replace udelay polling with jiffiesAntti Palosaari2014-09-211-9/+20
| | | | | | | | | udelay based I/O polling loop is a bad idea, especially system performance point of view. Kernel jiffies are preferred solution for such situations. Use it instead. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] it913x: refactor code largelyAntti Palosaari2014-09-211-162/+194
| | | | | | | | | | Refactor code largely. Try to keep order of register read/write same as windows driver does as it makes comparing sniffs easier. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] it913x: get rid of script loader and and private header fileAntti Palosaari2014-09-211-32/+31Star
| | | | | | | | | | | | Used script loader is quite useless and hides register numbers making code hard to understand. Get rid of it and use standard RegMap register write functions directly. it913x_priv.h file leaves empty after that change and is also removed.

| | | | | | | | | foo_dev seems to be most correct term for the structure holding data of each device instance. It is most used term in Kernel and also examples from book Linux Device Drivers, Third Edition, uses it.

* [media] it913x: change reg read/write routines more commonAntti Palosaari2014-09-211-31/+27Star
| | | | | | | | | | | Change register write and read routines to similar which are typically used. We have to add processor core as a part of register address in order to simplify register access. Chip has two cores, called link and ofdm. As for now, use address bit 24 to address used core. Bits 15:0 are register address in given core.

| | | | | | | | | | | Change the it913x driver to use the I2C high lever tuner binding model. As af9035 depends on it, add a code there to do the binding.

* [media] it913x: rename tuner_it913x => it913xAntti Palosaari2014-09-211-0/+463
| | | | | | | | | | Remove tuner_ prefix from module name and file names. Prefix was added due to file name conflict on media out-tree build system. Demodulator having same name does not exists anymore. So lets remove dumb prefix. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] it913x: rename its tuner driver to tuner_it913xMauro Carvalho Chehab2013-04-171-447/+0Star
| | | | | | | | | | | | | | | | | | | | There are three drivers with *it913x name on it, and they all belong to the same device: a tuner, at it913x.c; a frontend: it913x-fe.c; a bridge: it913x.c, renamed to dvb_usb_it913x by the building system. This is confusing. Even more confusing are the two .c files with the same name under different directories, with different contents and different functions. So, prepend the tuner one. This also breaks the out-of-tree compilation system.
