Subject: [PATCH v4 1/2] arm64: dts: rockchip: add "rockchip, grf" property for RK3399 PMUCRU/CRU
Date: Tue, 10 Jan 2017 14:15:29 +0800 [thread overview]
Message-ID: <1484028930-20305-2-git-send-email-zhengxing@rock-chips.com> (raw)
In-Reply-To: <1484028930-20305-1-git-send-email-zhengxing@rock-chips.com>
The structure rockchip_clk_provider needs to refer the GRF regmap
in somewhere, if the CRU node has not "rockchip,grf" property,
calling syscon_regmap_lookup_by_phandle will return an invalid GRF
regmap, and the MUXGRF type clock will be not supported.
Therefore, we need to add them.
