Subject: [PATCH v4 13/20] ARM: dts: Add bus nodes using VDD_INT for Exynos3250
Date: Mon, 14 Dec 2015 15:38:17 +0900 [thread overview]
Message-ID: <1450075104-13705-14-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1450075104-13705-1-git-send-email-cw00.choi@samsung.com>
This patch adds the bus nodes using VDD_INT for Exynos3250 SoC.
Exynos3250 has following AXI buses to translate data between
DRAM and sub-blocks.
Following list specifies the detailed relation between DRAM and sub-blocks:
- ACLK400 clock for MCUISP
- ACLK266 clock for ISP
- ACLK200 clock for FSYS
- ACLK160 clock for LCD0
- ACLK100 clock for PERIL
- GDL clock for LEFTBUS
- GDR clock for RIGHTBUS
- SCLK_MFC clock for MFC
