V4L/DVB (5636): Integrate all users of the fmd1216 tuner with dvb-pll
Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence and a sleep sequence. The init sequence sets the AGC control register to 0xa0, selecting the fast time constant and 112 dBuV take-over point. This the recommended value for DVB-T operation. The sleep sequence sets bit P4 (which is believed to turn the analog demodulator on), turns off the tuning voltage, and sets the AGC control register to 0x60 (external AGC voltage, the recommended value for analog operation). The existing dvb-pll users in the cx88 driver, listed below, will gain these init and sleep sequences. CX88_BOARD_HAUPPAUGE_HVR1100 Hauppauge WinTV-HVR1100 DVB-T/Hybrid CX88_BOARD_HAUPPAUGE_HVR1100LP Hauppauge WinTV-HVR1100 DVB-T/Hybrid (Low Profi CX88_BOARD_WINFAST_DTV2000H WinFast DTV2000 H CX88_BOARD_HAUPPAUGE_HVR3000 Hauppauge WinTV-HVR3000 TriMode Analog/DVB-S/DV CX88_BOARD_HAUPPAUGE_HVR1300 Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod This non-dvb-pll user in the cx88 driver should only gain the sleep sequence, as it already had an equivalent init sequence. The non-dvb-pll code for this user is removed. X88_BOARD_DNTV_LIVE_DVB_T_PRO digitalnow DNTV Live! DVB-T Pro In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll: SAA7134_BOARD_MD7134 Medion 7134 SAA7134_BOARD_ASUS_EUROPA2_HYBRID Asus Europa2 OEM The saa7134 functions philips_fmd1216_tuner_init(), philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are deleted and the dvb-pll versions are used. This should result in equivalent sleep, init, and tuning sequences being sent to the tuner. For the cxusb driver, only one board is effected: USB_PID_MEDION_MD95700 Medion MD95700 This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c() for init and tuning, respectively. These functions are effectively the same as the dvb-pll versions. They call a tuner pass control function defined at the dvb-usb level, but this does not matter, as this card does not have a tuner pass control function (only the dib3000mb does). This board will gain the sleep sequence, while init and tuning should be unchanged.
