From 5f609d8960f0ad4f5bd59a69facaeb2739c6e625 Mon Sep 17 00:00:00 2001 From: Mathew McBride Date: Mon, 18 Mar 2024 13:03:55 +1100 Subject: [PATCH] base-files: armsr: number Ten64 GPIOs according to kernel version A change in kernel 6.2[1] caused the base numbers of GPIOs to change significantly on some architectures like aarch64. We have to number our GPIOs accordingly. Ideally the board.d scripts should look through sysfs to find the basenum (like cat "/sys/devices/platform/soc/2000000.i2c/ i2c-0/0-0076/gpio/gpiochip640/base"), but the problem is that this occurs before modules are loaded, meaning I2C and other runtime devices may be missing.
