From 366384e495511bea8583e44173629a3012d62db0 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Wed, 18 Jan 2023 13:49:51 +0100 Subject: [PATCH] ARM: dts: stm32: Update part number NVMEM description on stm32mp131 The STM32MP13x Device Part Number (also named RPN in reference manual) only uses the first 12 bits in OTP4, all the other bit are reserved and they can be different of zero; they must be masked in NVMEM result, so the number of bits must be defined in the nvmem cell description.
