From 7cd1bb48885449a9323c7ff0f10012925e93b4e1 Mon Sep 17 00:00:00 2001 From: Sergio Paracuellos Date: Mon, 19 Jun 2023 06:09:37 +0200 Subject: [PATCH 5/9] mips: ralink: rt3883: remove clock related code A properly clock driver for ralink SoCs has been added. Hence there is no need to have clock related code in 'arch/mips/ralink' folder anymore.
