From 9ad2857c82d56017402256fd3e2ed401cc7f6fb9 Mon Sep 17 00:00:00 2001 From: Martin Kurbanov Date: Mon, 10 Feb 2025 17:34:16 +0300 Subject: mtd: spinand: otp: add helpers functions The global functions spinand_otp_read() and spinand_otp_write() have been introduced. Since most SPI-NAND flashes read/write OTP in the same way, let's define global functions to avoid code duplication.
