* media: dvb: represent min/max/step/tolerance freqs in HzMauro Carvalho Chehab2018-08-021-5/+5
| | | | | | | | | | | | | | | | Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

* media: rtl2832: use 64-bit arithmetic instead of 32-bit in rtl2832_set_frontendGustavo A. R. Silva2018-02-261-2/+2

Notice that this constant is used in a context that expects an expression of type u64 (64 bits, unsigned). The expression dev->pdata->clk * 7 is currently being evaluated using 32-bit arithmetic.

* [media] dvb: make DVB frontend *_ops instances "const"Max Kellermann2016-11-181-1/+1
| | | | | | | | | | | | | These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!

* [media] rtl2832: change the i2c gate to be mux-lockedPeter Rosin2016-05-041-164/+26
| | | | | | | | | | | | | | | | The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the regmap overrides that makes the i2c accesses unlocked and use plain old regmap accesses. This also removes the need for the regmap wrappers used by rtl2832_sdr, so deconvolute the code further and provide the regmap handle directly instead of the wrapper functions.

* [media] dvb_frontend: pass the props cache to get_frontend() as argMauro Carvalho Chehab2016-02-041-2/+2
| | | | | | | | | | | | | | | | | Instead of using the DTV properties cache directly, pass the get frontend data as an argument. For now, everything should remain the same, but the next patch will prevent get_frontend to affect the global cache. This is needed because several drivers don't care enough to only change the properties if locked. Due to that, calling G_PROPERTY before locking on those drivers will make them to never lock. Ok, those drivers are crap and should never be merged like that, but the core should not rely that the drivers would be doing the right thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner. It's based on the following components: - USB bridge: RTL2832P (contains also DVB-T demodulator) - Demodulator: Si2168-A30 - Tuner: Si2148-A20 The demodulator and the tuner will need firmwares. The Si2148 uses Si2158 firmware. Antti has the firmwares available for download: http://palosaari.fi/linux/v4l-dvb/firmware/ Do note that for DVB-T either of the demodulators can be used. DVB-C and DVB-T2 are only supported by the Si2168 demodulator. The driver will register 2 frontends for the same adapter. Frontend 0 will be the RTL2832 demodulator and frontend 1 will be the Si2168 demodulator. The same tuner is used for both. As a consequence of the above, it's recommended to use application that does implement proper DVBv5 support. For some reason, the old I2C write method sporadically fails. Thus the need for an option to only use the new I2C write method supported by the RTL2832.

| | | | | | | | | | | | | | | | 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.

* [media] rtl2832: remove exported resourcesAntti Palosaari2015-02-031-138/+0
| | | | | | | | | Exported resources are not needed anymore as all users are using callbacks carried via platform data. Due to that we will remove those. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | Add callback for all of those functions which are currently exported using EXPORT_SYMBOL. That allows us convert every user to callbacks and eventually all exported symbols could be removed.
