Subject: [RFC PATCH 01/11] clk: imx: add structure to extend register accesses
Date:   Sat, 31 Dec 2022 11:47:26 +0100

The imx_clk_reg structure allows accessing both registers that belong to
specific modules and those that are registered in syscon through the use
of the regmap API.
This is a preparation patch for the upcoming support to setup clocks
directly from the device tree.
