Subject: [PATCH v9 11/20] ARM: dts: Add DMC bus node for Exynos3250
Date: Mon, 11 Apr 2016 12:57:49 +0900 [thread overview]
Message-ID: <1460347078-15175-12-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1460347078-15175-1-git-send-email-cw00.choi@samsung.com>
This patch adds the DMC (Dynamic Memory Controller) bus node for Exynos3250 SoC.
The DMC is an AMBA AXI-compliant slave to interface external JEDEC standard
SDRAM devices. The bus includes the OPP tables and the source clock for DMC
block.
Following list specifies the detailed relation between the clock and DMC block:
- The source clock of DMC block : div_dmc
