Subject: [PATCH 16/19] arm64: dts: exynos: Add SPI/PDMA dt node for Exynos5433
This patch adds SPI (Serial Peripheral Interface) dt node for Exynos5433 SoC.
SPI transfers serial data by using various peripherals. SPI includes
8-bit/16-bit/32-bit shift registers to transmit and receive data. PDMA is used
for SPI communication.
