[PATCH] arm: dts: pxa3xx: Add ssp ports to pxa3xx device tree
From: daniel@zonque.org (Daniel Mack)
Date: 2018-06-24 17:41:34
Also in:
linux-devicetree
Subsystem:
open firmware and flattened device tree bindings, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Liam Girdwood, Mark Brown, Linus Torvalds
Also fix the documentation for these bindings. The DMA properties have to be passed in the ssp users for now.
