From ef13f8b64728c4b4d28639bbcf30fe1314b18482 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 26 Oct 2022 15:46:58 +0200 Subject: clk: Store clk_core for clk_rate_request The struct clk_rate_request is meant to store the context around a rate request such as the parent, boundaries, and so on. However, it doesn't store the clock the rate request is submitted to, which makes debugging difficult. Let's add a pointer to the relevant clk_core instance in order to improve the debugging of rate requests in a subsequent patch.
