Subject: [Patch v4 04/10] ARM: dts: lpc32xx: Add missing dma and i2s properties
Adds properties declared in the new DT bindings:
- nxp,lpc3220-i2s.yaml
- nxp,lpc3220-dmamux.yaml
for dma router/mux and I2S interface.
Signed-off-by: Piotr Wojtaszczyk <piotr.wojtaszczyk@...esys.com>
---
Changes for v4:
- This patch is renamed from
"ARM: dts: lpc32xx: Add missing properties for the i2s interfaces"
to describe dma changes as well
- Added dmas and dma-names properties in to all node which have dma request signals
- Add bus properties to pl08x dma node since they are removed from platform data in phy3250.c
- Put clock-controller@0 and dma-router@7c under the same syscon, simple-mfd device
Changes for v3:
- Split previous commit for separate subsystems
- Add properties to match dt binding
