This patch adds the AMBA bus nodes using VDD_INT for Exynos542x SoC.
Exynos542x has the following AMBA buses to translate data between
DRAM and sub-blocks.
Following list specifies the detailed correlation between sub-block and clock:
- CLK_DOUT_ACLK400_WCORE clock for WCORE's AXI
- CLK_DOUT_ACLK100_NOC for NoC (Network on Chip)'s AXI
- CLK_DOUT_PCLK200_FSYS for FSYS's APB
- CLK_DOUT_ACLK200_FSYS for FSYS's AXI
- CLK_DOUT_ACLK200_FSYS2 for FSYS2's AXI
- CLK_DOUT_ACLK333 for MFC's AXI
- CLK_DOUT_ACLK266 for GEN's AXI
- CLK_DOUT_ACLK66 for PERIC/PERIR's AXI
- CLK_DOUT_ACLK333_G2D for G2D's AXI
- CLK_DOUT_ACLK266_G2D for ACP's AXI
- CLK_DOUT_ACLK300_JPEG for JPEG's AXI
- CLK_DOUT_ACLK166 for JPEG's APB
- CLK_DOUT_ACLK300_DISP1 for FIMD's AXI
- CLK_DOUT_ACLK400_DISP1 for DISP1's AXI
- CLK_DOUT_ACLK300_GSCL for GSCL Scaler's AXI
- CLK_DOUT_ACLK400_MSCL for MSCL's AXI
