The dts and dtsi add support for msm8916 variant of Samsung Galaxy J3 SM-J320YZ smartphone released in 2016. Add a device tree for SM-J320YZ with initial support for: - GPIO keys - SDHCI (internal and external storage) - USB Device Mode - UART (on USB connector via the SM5703 MUIC) - WCNSS (WiFi/BT) - Regulators - QDSP6 audio - Speaker/earpiece/headphones/microphones via digital/analog codec in MSM8916/PM8916 - WWAN Internet via BAM-DMUX - Touchscreen - Accelerometer There are different variants of J3, with some differences in MUIC, sensor, NFC and touch key I2C buses. The common parts are shared in msm8916-samsung-j3-common.dtsi to reduce duplication.
