2011-01-19[media] saa7134: Kworld SBTVD: make both analog and digital to workMauro Carvalho Chehab1-6/+10
There are some weird bugs at tda8290/tda18271 initialization, as it insits do do analog initialization during DVB frontend attach: DVB: registering new adapter (saa7133[0]) DVB: registering adapter 0 frontend 0 (Fujitsu mb86A20s)... mb86a20s: mb86a20s_initfe tda18271_write_regs: [2-0060|M] ERROR: idx = 0x5, len = 1, i2c_transfer returned: -5 tda18271_init: [2-0060|M] error -5 on line 830 tda18271_tune: [2-0060|M] error -5 on line 908 tda18271_write_regs tda18271_write_regs: [2-0060|M] ERROR: idx = 0x5, len = 1, i2c_transfer returned: -5 tda18271c2_rf_tracking_filters_correction: [2-0060|M] error -5 on line 265 tda18271_write_regs tda18271_write_regs: [2-0060|M] ERROR: idx = 0x25, len = 1, i2c_transfer returned: -5 tda18271_channel_configuration: [2-0060|M] error -5 on line 119 tda18271_set_analog_params: [2-0060|M] error -5 on line 1045 tda18271_set_analog_params: [2-0060|M] error -5 on line 1045 tda829x 2-004b: tda8295 not locked, no signal? tda829x 2-004b: tda8295_i2c_bridge: disable i2c gate tda829x 2-004b: tda8295 not locked, no signal? tda829x 2-004b: tda8295_i2c_bridge: disable i2c gate mb86a20s_i2c_writereg: writereg error (rc == -5, reg == 0x29, data == 0x33) mb86a20s: Init failed. Will try again later The problem is that mb86a20s is only visible if the analog part is disabled. However, due to a trick at mb86a20s, it will later initialize properly: mb86a20s: mb86a20s_initfe: Initialization succeded. This is hacky and ugly. However, I coldn't find any easy way to fix it. A proper fix would be to have a resource locking schema, used by both V4L and DVB parts that would block access to analog registers while digital registers are in use, but this will probably put tda829x into a dead lock.

The hybrid tuner FMD1216MEX_MK3 after cold start has disabled IF. This tuner has internal I2C switch. This switch switch I2C bus between DVB-T and IF part. Default state is DVB-T. When module saa7134 is load it can't find IF tda9887 and disable analog TV mode. Sets internal I2C switch of the tuner to IF by send special value to the tuner as for receive analog TV from low band. It can be usefule for other cards. I didn't set configure a tuner by a tuner model because this tuner can have different I2C address. May be we can do it later after discuss for more robust support a tuners. Signed-off-by: Beholder Intl. Ltd.

http://linuxtv.org/wiki/index.php/Zolid_Hybrid_TV_Tuner test status analog (PAL-B): - Sometimes picture is noisy, but it becomes crystal clear after switching between channels. (happens for example at 687.25 Mhz) - On a lower frequency (511.25 Mhz) the picture is always sharp, but lacks colour. - No sound problems. - radio untested. Digital: - DVB-T/H stream reception works. - Would expect to see some more channels in the higher frequency region.
