X-Git-Tag: v6.14-rc1~59^2~19
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4dd7c9d94806dd4f96d91a06e34f3142e386a534;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: serial: sc16is7xx: Add description for polling mode

Polling mode is enabled if the "interrupts" property is missing.
Thus, this commit deletes "interrupts" entry from "required" section
and adds a description for the fallback to polling mode at the
"interrupts" entry.
