The X-Powers AXP803 and AXP813 PMICs are close to the AXP809 with some
more outputs.
Signed-off-by: Jean-Francois Moine <moin...@free.fr>
---
The AXP813 has been tested in a Banana PI M3 board (needed for WiFi/BT).
v2:
- fix lack of support of dcdc frequency
- notice that the AXP803 is also handled
- send the patch to the DT maintainers
