From f5ac5ac12dd678f0abe708baa55a5049a44b7ab8 Mon Sep 17 00:00:00 2001 From: Kuldeep Singh Date: Mon, 30 Mar 2020 16:46:30 +0530 Subject: [PATCH] arm64: dts: ls1012a: Add QSPI node properties Add support for QSPI on NXP layerscape LS1012A-RDB, LS1012A-QDS, LS1012A-FRDM and LS1012A-FRWY boards. LS1012A-RDB has 2 Spansion "s25fs512s" flashes of size 64M each and only one can be accessed at a time. LS1012A-QDS/FRDM has 1 spansion "s25fs512s" flash of size 64M. LS1012A-FRWY has one winbond "w25q16dw" flash of size 2M. Use generic compatibles as "jedec,spi-nor" for automatic detection of flash. Configure RX and TX buswidth values as 2 as only two I/O lines are available for data transfer. Add ls1012a(si) node alongwith flash nodes.
