Subject: [PATCH] overlays: Use current I2C Sysfs in README examples
|
|
|
|
Linux v6.12 (7e722083fcc3e) removed I2C_COMPAT making
|
|
/sys/class/i2c-adapter no longer available in userspace. This commit
|
|
adjusts the dtoverlays documentation to refer to the current I2C Sysfs
|
|
(/sys/bus/i2c/devices).
