We generated a define for each instance to convey its existance of the form: #define DT_<COMPAT>_<INSTANCE> 1 However we renamed all other instance defines to be of the form DT_INST_<INSTANCE>_<FOO>. To make things consistent we now generate a define of the form: #define DT_INST_<INSTANCE>_<COMPAT> 1 We also now deprecate the DT_<COMPAT>_<INSTANCE> form and fixup all uses to use the new form. Fixes: #17650 Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
