From 9b60daf62dd7c02164c53f2baa72e3e6c8af441f Mon Sep 17 00:00:00 2001 From: Alex Voinea Date: Thu, 22 Dec 2022 03:23:23 +0100 Subject: tmc: Configurable microstep lookup table (#5920) Make all the microstep lookup table registers configurable via the config file. It also loads the default values. TMC220x and TMC2660 do not support this feature.
