[PATCH v6 21/21] ARM: dts: Add support of bus frequency for exynos4412-trats/odroidu3

Show all headers | View raw

THis patch adds the bus device tree nodes for both MIF (Memory) and INT
(Internal) block to enable the bus frequency.

The DMC bus is parent device in MIF block using VDD_MIF and the LEFTBUS
bus is parent device in INT block using VDD_INT.
