From ab4d14528fdf946dfa7177b53e64f78bf8cce03a Mon Sep 17 00:00:00 2001 From: Satoshi Nagahama Date: Fri, 6 May 2016 16:35:05 -0300 Subject: [PATCH] [media] em28xx: add support for PLEX PX-BCUD (ISDB-S) 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.
