* [media] lmedm04: Create frontend call back for read statusMalcolm Priestley2015-02-031-145/+60
| | | | | | | | | | | | | | | | | | | | | | | Create dm04_read_status to check lock through either interrupt values or directly by the call back. When the device is not streaming the frontends original call back is used. When streaming has started it turns off I2C messaging by setting st->i2c_talk_onoff to zero. I2C can only be turn on again by one of the other allowed frontend calls. All old code is removed from lme2510_msg and this function only needs to set st->i2c_talk_onoff to 1. The lock status is saved and when the frondend is locked is maintained by lme2510_int_response who will now just kill the lock. The call back for rs2000 tuner is nologer required. All frontend types have been tested. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] rtl2832: implement own lock for regmapAntti Palosaari2015-02-032-10/+40

* [media] rtl2832: remove internal mux I2C adapterAntti Palosaari2015-02-032-21/+4
| | | | | | | | | | | | | | | | There was 2 muxed I2C adapters, one for demod tuner bus and one for internal use. Idea of internal I2C adapter was to force I2C repeater close when demod access its registers. Driver has also delayed work queue based method to close I2C repeater. After regmap conversion internal I2C adapter based repeater close left unused - only work queue method was in use. We could not use internal mux adapter method with regmap as it makes recursive regmap call, which causes deadlock as regmap has own locking. Due to that remove whole method totally.
