From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Lezcano Subject: [PATCH V4] ARM64: dts: hi6220-hikey: Add clock binding for the pmic mfd Date: Mon, 24 Apr 2017 22:40:22 +0200 Message-ID: <1493066439-6889-1-git-send-email-daniel.lezcano@linaro.org> Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: xuwei5-C8/M+/jPZTeaMJb+Lgu22Q@public.gmane.org Cc: Arnd Bergmann , Stephen Boyd , Michael Turquette , Rob Herring , Lee Jones , Rob Herring , Mark Rutland , Catalin Marinas , Will Deacon , "open list:OPEN FIRMWARE AND..." , open list , "moderated list:ARM/HISILICON SOC..." List-Id: devicetree@vger.kernel.org The hi655x PMIC provides the regulators but also a clock. The latter is missing in the definition and in the DT, thus it is no possible to enable the WiFi which depends on this clock. The hi655x's clock has been added and the hi655x multifunction driver has updated with a clock-cell. This patch adds the clock-cells for the PMIC in the DT and updates the documentation.
