Subject: [PATCH v3 12/14] dt-bindings: mtd: gpmi-nand: Fix matching of clocks on different SoCs
Date: Fri,  4 Sep 2020 17:24:02 +0200
Message-ID: <20200904152404.20636-13-krzk@kernel.org> (raw)
In-Reply-To: <20200904152404.20636-1-krzk@kernel.org>

Driver requires different amount of clocks for different SoCs.  Describe
these requirements properly to fix dtbs_check warnings like:

    arch/arm64/boot/dts/freescale/imx8mm-beacon-kit.dt.yaml: nand-controller@33002000: clock-names:1: 'gpmi_apb' was expected

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

Changes since v1:
1. Do not require order of clocks (use pattern).
