Re: [PATCH v8 3/3] ARM: dts: Add initial device tree support for EXYNOS5410

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Since I've started enforcing reference-based DT syntax due to multiple advantages over the plain full-tree based one, you should do the same for your dts/i files. You can take the series adding support for Exynos5260 as an example:

Best regards,
Tomasz
