From 5efe54b26d470785883bec0264d8d5e145715038 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 5 May 2021 15:35:34 +0200 Subject: [PATCH] clk: Always clamp the rounded rate The current core while setting the min and max rate properly in the clk_request structure will not make sure that the requested rate is within these boundaries, leaving it to each and every driver to make sure it is. Add a clamp call to make sure it's always done.
