Re: [PATCH] [TEST] Regarding m88rc2000 i2c gate operation, SNR, BER and others
This patch restores more less as before, except; Corrected snr/signal strength are swapped. m88rs2000_set_voltage is now called inside dm04_lme2510_set_voltage this seems to stop intermittent loss of device during channel change/scan. Unfortunately, lmedm04 cannot support ucblocks or ber, neither are returned in the interrupt callback. I am working on a patch to map them back in when streaming is off.
