Malcolm Priestley 8272d0a0c0 [media] m88rs2000: prevent frontend crash on continuous transponder scans
Add m88rs2000_get_tune_settings, min delay of 2000 ms on symbol
rate more than 3000000 and delay of 3000ms less than this.

Adding min delay prevents crashing the frontend on continuous
transponder scans. Other dvb_frontend_tune_settings remain as default.

This makes very little time difference to good channel scans, but slows down
the set frontend where lock can never be achieved i.e. DVB-S2.

Malcolm Priestley dd4491dfb9 [media] m88rs2000: set symbol rate accurately
Current setting of symbol rate is not very actuate causing
loss of lock.

Covert temp to u64 and use mclk to calculate from big number.

Calculate symbol rate by dividing symbol rate by 1000 times
1 << 24 and dividing sum by mclk.

Add other symbol rate settings to function registers 0xa0-0xa3.

In set_frontend add changes to register 0xf1 this must be done
prior call to fe_reset. Register 0x00 doesn't need a second
write of 0x1

Applied after patch

Malcolm Priestley 06af15d1b6 [media] m88rs2000: add m88rs2000_set_carrieroffset
Set the carrier offset correctly using the default mclk values.

Add function m88rs2000_get_mclk to calculate the mclk value
against crystal frequency which will later be used for
other functions.

Add function m88rs2000_set_carrieroffset to calculate
and set the offset value.

variable offset becomes a signed value.

Register 0x86 is set the appropriate value according to
remainder value of frequency % 192857 calculation as
shown.

Malcolm Priestley a0a030bdbe [media] ts2020: call get_rf_strength from frontend
Restore ds3000.c read_signal_strength.
Call tuner get_rf_strength from frontend read_signal_strength.
We are able to do a NULL check and doesn't limit the tuner
attach to the frontend attach area.
At the moment the lmedm04 tuner attach is stuck in frontend
attach area.
