Subject: [PATCH v2 1/4] pwm: meson: switch to using struct clk_parent_data for mux parents
Date: Tue, 11 Apr 2023 21:22:33 +0200	[thread overview]
Message-ID: <2760498e-23a6-f787-bac2-0460566a995d@gmail.com> (raw)
In-Reply-To: <0f087629-810d-f0e0-bf0b-05ca5defc16d@gmail.com>

We'll use struct clk_parent_data for mux/div/gate initialization in the
follow-up patches. As a first step switch the mux from using
parent_names to clk_parent_data.
