2019-10-16	media: tuners/qm1d1c0042: Use DIV_ROUND_CLOSEST directly to make it readable	zhong jiang	1	-1/+1
	The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable. Signed-off-by: Zhong Jiang <zhongjiang@huawei.com> Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-08-02	media: dvb: convert tuner_info frequencies to Hz	Mauro Carvalho Chehab	1	-2/+2
	Right now, satellite tuner drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal tuners 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 tuners. So, convert everything to specify tuner frequencies in Hz. Plese notice that a similar patch is also needed for frontends.

2016-05-06	[media] em28xx: add support for PLEX PX-BCUD (ISDB-S)	Satoshi Nagahama	1	-11/+27
	PX-BCUD has the following components: USB interface: Empia EM28178 Demodulator: Toshiba TC90532 (works by code for TC90522) Tuner: Next version of Sharp QM1D1C0042 em28xx_dvb_init(): add init code for PLEX PX-BCUD with calling px_bcud_init() that does things like pin configuration. qm1d1c0042_init(): support the next version of QM1D1C0042, change to choose an appropriate array of initial registers by reading chip id.
