From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
Add the DT node for the VBATTB IP along with DT bindings for the clock
it provides.
Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
---
Changes in v3:
- dropped the child nodes of vbattb; along with this dropped ranges,
interrupt-names, #address-cells, #size-cells
- added vbattb_xtal as input clock for vbattb
Changes in v2:
- update compatibles
- updated clocks and clock-names for clock-controller node
- removed the power domain from the clock-controller as this is
controlled by parent node in v2
