From 797255d897d635799fbb878262b7491e07ceac9e Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 13 Aug 2025 23:25:56 +0200 Subject: [PATCH] arm64: dts: renesas: r8a779g3: Describe generic SPI NOR support on Retronix R-Car V4H Sparrow Hawk board Retronix R-Car V4H Sparrow Hawk EVTA1 is populated with Spansion S25FS512S, EVTB1 is populated with Winbond W77Q51NW. Describe the SPI NOR using generic "jedec,spi-nor" compatible, because both flashes can be auto-detected based on their built-in IDs.
