[PATCH v3 0/1] watchdog: realtek-otto: Make use of regmap API

[Rustam Adilov <adilov@disroot.org>]

This patch series changes the driver to use regmap API for all of the
register access stuff instead of the ioread32 and iowrite32 with __iomem.
That makes the watchdog operable when SWAP_IO_SPACE config is enabled just
by adding big-endian property to the device tree node.

Also, there was a comment by sashiko which got addressed by Sander in [2]
with possibility of it being false positive so i left it at that.
