From 42b6515fd55d5c4dbeb8183ad18b289182e80456 Mon Sep 17 00:00:00 2001 From: Daniel Scheller Date: Sun, 25 Feb 2018 07:31:34 -0500 Subject: [PATCH] media: ngene: add support for Sony CXD28xx-based DuoFlex modules Recognize (probe) and support (attach) all Sony CXD28xx based DuoFlex addon modules/cards, namely the DuoFlex CT2 (CXD2837), ISDB-T (CXD2838), C2T2 (CXD2843) and C2T2I (CXD2854). Since all these modules are equipped with a MachXO2 interface, that support is required for the hardware to work. This functionality utilises the auxiliary cxd2841er and tda18212 drivers. This also adds autoselection (if MEDIA_SUBDRV_AUTOSELECT) of the CXD2841ER demod driver to Kconfig. The __maybe_unused annotation can now be removed from the xo2names array.
