This series adds support for the P2WI block used by some Allwinner boards
to interface with the AXP221 PMIC.

Best Regards,


Changes since v4:
- add P2WI protocol description in driver header comment
- remove unneeded i2c address check
- remove unneeded irq field from p2wi struct

Changes since v3:
- update the DT bindings doc
- fix a comment that was no longer true

Changes since v2:
- drop the initialization (switch from I2C to P2WI mode) part
- print devm_ioremap_resource err code
