From: Rob Herring (Arm) Date: Sun, 8 Jun 2025 22:42:51 +0000 (-0500) Subject: dt-bindings: Move sophgo,cv1800b-rtc to rtc directory X-Git-Tag: io_uring-6.17-20250815~53^2~33 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=590951f908f25c7e4d6822f0109e7e230d7b0a89;p=linux-block.git dt-bindings: Move sophgo,cv1800b-rtc to rtc directory The $id path for the sophgo,cv1800b-rtc binding was missing part of the path 'soc'. However, the correct place for RTC bindings (even if it's also a "syscon") is the rtc directory, so move the binding there while fixing the $id value.
