* [media] lgdt3305: include sleep functionality in lgdt3304_opsShuah Khan2014-04-071-0/+1
| | | | | | | | | | | | Add sleep ops to lgdt3304_ops to invoke lgdt3305_sleep() to be called from dvb_frontend_suspend(). lgdt3305_soft_reset() is called for both 3304 and 3305 devices. soft_reset and sleep touch LGDT3305_GEN_CTRL_3 on 3304 and 3305 devices. Hence, adding sleep to lgdt3304_ops will help suspend 3304 properly from dvb_frontend_suspend().

* [media] drx-j: use customise option correctlyPaul Bolle2014-04-071-1/+1
| | | | | | | | | | | | The Kconfig entry for "Micronas DRX-J demodulator" defaults to modular if DVB_FE_CUSTOMISE is set. But that Kconfig symbol was replaced with MEDIA_SUBDRV_AUTOSELECT as of v3.7. So use the new symbol. And negate the logic, because MEDIA_SUBDRV_AUTOSELECT's logic is the opposite of the former logic.

* [media] af9033: Don't export functions for the hardware filterMauro Carvalho Chehab2014-03-152-13/+24
| | | | | | | | | | | | | | | | | | | | | | | | Exporting functions for hardware filter is a bad idea, as it breaks compilation if: CONFIG_DVB_USB_AF9035=y CONFIG_DVB_AF9033=m Because the PID filter function calls would be hardcoded at af9035. The same doesn't happen with af9033_attach() because the dvb_attach() doesn't hardcode it. Instead, it dynamically links it at runtime. However, calling dvb_attach() multiple times is problematic, as it increments module kref. So, the better is to pass one parameter for the af9033 module to fill the hardware filters, and then use it inside af9035.

| | | | | | | | | | | | | It was possible that tuner_frequency variable, used for carrier offset compensation, was uninitialized. That happens when tuner .get_frequency() callback is not defined.

| | | | | | | | | | | | | | | There are large chunks of code at drx-j that aren't used. Most of them are due to analog TV support. Well, just enabling them won't make analog support work, as devices with DRX and analog support requires an extra chip (avf4910). We don't have drivers for it, nor the current device that uses this frontend has support for analog TV. So, let's just get rid of this code.

* | [media] drx-j: Use single master modeMauro Carvalho Chehab2014-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | There are no other I2C masters here. Also, the Windows driver uses this mode (and both drxd and drxk Kernel drivers). So, switch to it. That helps to compare the logs between the Linux driver and the Windows one. Acked-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* | [media] drx-j: Allow userspace control of LNAMauro Carvalho Chehab2014-03-041-0/+41
| | | | | | | | | | | | | | | | Instead of just disabling the LNA every time, allow to control it from userspace. Acked-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* | [media] drx-j: get rid of function wrappersMauro Carvalho Chehab2014-03-042-1186/+1026
| | | | | | | | | | | | | | | | | | On several places, the I2C functions are just wrappers to others. Get rid of it. Acked-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
