Subject: [PATCH v2 3/4] arm64: dts: add DRAMC node for MT6779
Date: Fri, 16 Apr 2021 17:32:17 +0800	[thread overview]
Message-ID: <1618565538-6972-4-git-send-email-pk.chi@mediatek.com> (raw)
In-Reply-To: <1618565538-6972-1-git-send-email-pk.chi@mediatek.com>

Add the DRAMC node for the DRAMC kernel driver.

Properties are divided into three categories:

- Platform DTS:
    MediaTek DRAMC platform common part.

- Project DTS:
    Runtime filled in by bootloader according to the board
    hardware configuration.

- Driver level:
    Hardware-specific register settings, encapsulated as
    compatible data for better DTS compatibility.
