[PATCH 3/4] ARM: dts: imx6sx: remove LDB reg property

From: Marco Felsch

Date: Mon May 04 2026 - 16:22:59 EST


The iomux-gpr syscon device has a very loose register definition. Many
registers have a multi purpose, e.g. one register controlls the WDG
behavior and the CSI2 mux settings. This would lead into multiple
sub-devices which use the same 'reg' which is wrong.

Instead of specifying the 'reg' in the OF each sub-device driver needs
to handle the correct bits on their own. Therefore drop the 'reg'
porperty from the bridge node as well as the @18 register suffix.
