[media] saa7134: Kworld SBTVD: make both analog and digital to work
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.
