From f5d82a75e666a6cc66453285cb3ce28c5d02397a Mon Sep 17 00:00:00 2001 From: Akihiro Tsukada Date: Mon, 8 Sep 2014 14:20:42 -0300 Subject: [PATCH] [media] tc90522: add driver for Toshiba TC90522 quad demodulator This patch adds driver for tc90522 demodulator chips. The chip contains 4 demod modules that run in parallel and are independently controllable via separate I2C addresses. Two of the modules are for ISDB-T and the rest for ISDB-S. It is used in earthsoft pt3 cards. Note that this driver does not init the chip, because the initilization sequence / register setting is not disclosed. Thus, the driver assumes that the chips are initilized externally by its parent board driver before fe->ops->init() are called. Earthsoft PT3 PCIe card, for example, contains the init sequence in its private memory and provides a command to trigger the sequence.
