From fa9e7ca4661d8d5a521ede511a496ae029748595 Mon Sep 17 00:00:00 2001 From: Sungbo Eo Date: Fri, 8 May 2020 21:00:48 +0900 Subject: [PATCH] ramips: simplify palmbus/{i2c,spi} in device DTS files As the node is already defined and labeled in SoC DTSI file, we can refer to it outside of root node and reduce redundancy. While at it, remove unused pcf8563 label.
