Subject: [PATCH 25/33] ARM: dts: exynos: Add S5M8767 clocks for RTC in Exynos4412 Origen
Date:   Sun, 30 Aug 2020 15:51:52 +0200
Message-Id: <20200830135200.24304-25-krzk@kernel.org>
In-Reply-To: <20200830135200.24304-1-krzk@kernel.org>
References: <20200830135200.24304-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add node for clock controller of Samsung S5M8767 PMIC.  This provides
the 32768 Hz clock required by S3C RTC.  Except making the S3C RTC
working, this also fixes dtbs_check warnings:

  arch/arm/boot/dts/exynos4412-origen.dt.yaml: rtc@10070000: clocks: [[7, 346]] is too short
  arch/arm/boot/dts/exynos4412-origen.dt.yaml: rtc@10070000: clock-names: ['rtc'] is too short
