Dear Takiguchi, I'm working on 'drivers/media/dvb-frontends/cxd2841er.c' (universal demod) and 'linux/drivers/media/dvb-frontends/helene.c' (universal TERR/CABLE/SAT tuner). How do you think - is your cxd2880 proposed driver have possibilities to cover cxd2841er demod functionality too ? I have quickly checked your cxd2880_top.c and looks like cxd2880 works over SPI (not I2C) ?Also, looks like registers map, sequences is different. Am I right ? How do you think ? Thanks a lot ! 2017-05-31 21:41 GMT-04:00 Takiguchi, Yasunari <Yasunari.Takiguchi@sony.com>: > Hi, all > > I sent the patch series of Sony CXD2880 DVB-T2/T tuner + demodulator driver on Apr/14. > Are there any comments, advices and review results for them? > > I'd like to get better understanding of current review status for our codes. > > Regards, > Takiguchi -- Abylay Ospan, NetUP Inc. http://www.netup.tv

Dear Takiguchi, Roger that.
