The S3C RTC requires 32768 Hz clock as input which is provided by PMIC. However the PMIC is not described in DTS at all so at least add a workaround to model its clock with a fixed-clock. This fixes S3C RTC and silences dtbs_check warnings like: arch/arm/boot/dts/exynos5410-smdk5410.dt.yaml: rtc@101e0000: clocks: [[5, 317]] is too short arch/arm/boot/dts/exynos5410-smdk5410.dt.yaml: rtc@101e0000: clock-names: ['rtc'] is too short Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200901075417.22481-5-krzk@kernel.org
