0x20004 does seem very even, please verify this size.
even though the reg space after that range is unused, the AOSS reset
driver is supposed to control only those listed reset lines

"AOSS reset clients"
yep this heading makes much more sense
Although you could probably get a way with just referring to reset.txt
and the header file.
+==============================================
+
+Device nodes that need access to reset lines should
+specify them as a reset phandle in their corresponding node as
+specified in reset.txt.
+
+For list of all valid reset indicies see
+<dt-bindings/reset/qcom,sdm845-aoss.h>
+
+Example:
+
+modem-pil@4080000 {
+ ...
+
+ resets = <&aoss_reset AOSS_CC_MSS_RESTART>;
+ reset-names = "mss_restart";
+
+ ...
+};

Apart from these nits this looks reasonable.
