From: Christian Lamparter Date: Mon, 15 Oct 2018 18:00:08 +0000 (+0200) Subject: apm821xx: apm82181.dtsi overhaul X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1d5d77612f0eb3aa435dc574aecd23b629b55b6d;p=openwrt%2Fstaging%2Fansuel.git apm821xx: apm82181.dtsi overhaul - order entries by mmio address where possible - switch to lower-case address values - comment on BSP u-boot behaviour in regards to what it edits and look for - annotate irq lines with the help of interrupt-names - remove deprecated "device_type" properties The pci and network device_type had to stay since they are required by the drivers and u-boot. the cpu and memory device_types will remain as well as they are still part of the DT Spec.
