2014-09-21[media] anysee: convert tda18212 tuner to I2C clientAntti Palosaari
Used tda18212 tuner is implemented as I2C driver. Implement I2C client to anysee and use it for tda18212. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2014-09-21[media] tda18212: prepare for I2C client conversionAntti Palosaari
We need carry pointer to frontend via config struct (I2C platform_data ptr) when I2C model is used. Add that pointer first in order to keep build unbreakable during conversion. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2014-09-21[media] af9035: remove I2C client differentlyAntti Palosaari
It crash kernel when device was removed while it was streaming. That is because we removed driver and frontend thread was still running.

2014-09-21[media] it913x: change reg read/write routines more commonAntti Palosaari
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.

2014-09-21[media] it913x: fix IT9135 AX sleepAntti Palosaari
Old IT9135 AX needs a little bit different register settings for sleep than newer IT9135 BX. This has been broken always, as power management of the whole driver, but it started to be problem as I fixed clock. Earlier clock was disabled very first on sleep and rest of the commands were skipped by the chip as no clock, leaving tuner full power state. When I fixed clocks these PM bugs started raising out as I/O errors.

2014-09-21[media] it913x: fix tuner sleep power leakAntti Palosaari
IT913x tuner driver disables own clock, provided by demod core, as very a first operation when tuner is put on *sleep*. That likely causes failure of all the rest commands on sleep sequence, which leads situation where tuner is not actually on sleep, but consuming a lot of power. I measured 102mA current consumption from the USB before change and after change it was only 32mA. Used device was single tuner IT9135 BX. Second reason to remove that register from tuner driver is reason it is simply on wrong driver (demod vs. tuner), breaking the principle of correct driver. Clock is now provided more correctly af9033 demod driver as a config option.

2014-09-21[media] af9033: provide dyn0_clk clock sourceAntti Palosaari
AF903x/IT913x demod provides clock source(s). It seems that this clock source is used for integrated RF tuner of IT913x. It is enabled by default, but firmware disables it automatically when suspend is requested (suspend_flag (0x004c) + trigger_ofsm (0x0000)). Automatic disable behavior seems to be similar for both AF903x and IT913x I tested, though there is no likely any real clock user in a case of AF903x.

2014-09-21[media] si2157: change command for sleepOlli Salonen
Instead of sending command 13 to the tuner, send command 16 when sleeping. This behaviour is observed when using manufacturer provided binary-only Linux driver for TechnoTrend CT2-4400 (Windows driver does not do power management). The issue with command 13 is that firmware loading is necessary after that. This is not an issue with tuners that do not require firmware, but starting streaming after sleep on an Si2158 takes noticeable time as firmware is loaded on resume.
