From 3ed741db04f58e8df0d46cec7ecfc4bfd075f047 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 14 Jan 2023 15:34:58 -0800 Subject: [PATCH] clk: vc5: Use `clamp()` to restrict PLL range The VCO frequency needs to be within a certain range and the driver enforces this. Make use of the clamp macro to implement this instead of open-coding it. This makes the code a bit shorter and also semanticly stronger.
