Subject: mfd: syscon: Use of_iomap() instead of ioremap()
X-Git-Tag: v5.15~341^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=452d07413954ef38951cfd41507b310c3afccd93;p=platform%2Fkernel%2Flinux-starfive.git

mfd: syscon: Use of_iomap() instead of ioremap()

This automatically selects between ioremap() and ioremap_np() on
platforms that require it, such as Apple SoCs.
