From 36bac0a193d4cf37ca9c482567bc72012c1299b5 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 24 Jun 2019 15:50:40 +0200 Subject: [PATCH] clk: Provide struct clk for fixed rate clock (clk_fixed_rate.c) Up till now the fixed rate clock ('osc') has been added to UCLASS_CLK without declaring struct clk. As a result it was only accessible by iterating the udevice's uclass list. This is a problem for clock code, which operates on pointers to struct clk (like clk_get_rate()), not udevices. After this change struct clk is accessible from udevice and udevice from struct clk.
