-From 32145a877f6e116d9bdc780558374782c5b7a4ef Mon Sep 17 00:00:00 2001
-From: Daniel Matuschek <info@crazy-audio.com>
-Date: Mon, 4 Aug 2014 11:09:58 +0200
-Subject: [PATCH 048/222] Added driver for HiFiBerry Amp amplifier add-on board
-
-The driver contains a low-level hardware driver for the TAS5713 and the
-drivers for the Raspberry Pi I2S subsystem.
-
-TAS5713: return error if initialisation fails
-
-Existing TAS5713 driver logs errors during initialisation, but does not return
-an error code. Therefore even if initialisation fails, the driver will still be
-loaded, but won't work. This patch fixes this. I2C communication error will now
-reported correctly by a non-zero return code.
-
-HiFiBerry Amp: fix device-tree problems
-
-Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.
