Subject: [PATCH v5 09/14] clk: microchip: mpfs: move id & offset out of clock structs
Date:   Fri, 9 Sep 2022 13:31:18 +0100
Message-ID: <20220909123123.2699583-10-conor.dooley@microchip.com>
In-Reply-To: <20220909123123.2699583-1-conor.dooley@microchip.com>

The id and offset are the only thing differentiating the clock structs
from "regular" clock structures. On the pretext of converting to more
normal structures, move the id and offset out of the clock structs and
into the hw structs instead.
