4 Subject: [PATCH] Added driver for HiFiBerry Amp amplifier add-on board
5
6 The driver contains a low-level hardware driver for the TAS5713 and the
7 drivers for the Raspberry Pi I2S subsystem.
8
9 TAS5713: return error if initialisation fails
10
11 Existing TAS5713 driver logs errors during initialisation, but does not return
12 an error code. Therefore even if initialisation fails, the driver will still be
13 loaded, but won't work. This patch fixes this. I2C communication error will now
14 reported correctly by a non-zero return code.
15
16 HiFiBerry Amp: fix device-tree problems
17
18 Some code to load the driver based on device-tree-overlays was missing. This is added by this patch.
