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@timesys.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 arch/arm/boot/dts/nxp/lpc/lpc32xx.dtsi | 53 +++++++++++++++++++++++--- 1 file changed, 48 insertions(+), 5 deletions(-)
