[PATCH v3 0/3] reset: amlogic-a4/a5: add reset driver

[PATCH v3 0/3] reset: amlogic-a4/a5: add reset driver

[zelong dong]

From: Zelong Dong <zelong.dong@amlogic.com>

This patchset adds Reset controller driver support for
Amlogic A4/A5 SoC. The RESET registers count and offset
for A4/A5 Soc are same as S4 Soc.

Changes since v2:
- rebase on 'amlogic,t7-reset' patchset

Changes since v1:
- remove 'amlogic,t7-reset'
- move 'amlogic,c3-reset' to the other enum list
- move reset node from amlogic-a4-common.dtsi to
  amlogic-a4.dtsi/amlogic-a5.dtsi

I'm not well versed in preferred dt-bindings style, but this items
looks superfluous to me. It only contains a single enum.

I think this can be merged together with the dts patches.

Hello Philipp, Conor,
Sorry for the late reply.

Do you mean to use 'amlogic,meson-s4-reset' for A4 and A5 directly, 
without the fallback?

No. We are saying that

+      - items:
+          - enum:
+              - amlogic,meson8b-reset # Reset Controller on Meson8b and compatible SoCs

is pointless duplication, because your "items" list only has only
entry in it (the enum) and you could just remove the "- items" line
entirely and have the same outcome.
