Subject: [PATCH 072/170] 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.
