This patch adds the bus nodes using VDD_INT for Exynos4x12 SoC.
Exynos4x12 has the following AXI buses to translate data between
DRAM and sub-blocks.
Following list specifies the detailed relation between DRAM and sub-blocks:
- ACLK100 clock for PERIL/PERIR/MFC(PCLK)
- ACLK160 clock for CAM/TV/LCD
: The minimum clock of ACLK160 should be over 160MHz.
When drop the clock under 160MHz, show the broken image.
- ACLK133 clock for FSYS
- GDL clock for LEFTBUS
- GDR clock for RIGHTBUS
- SCLK_MFC clock for MFC
