Subject[RFC PATCH v2 00/11] clk: imx8mn: setup clocks from the device tree
Date
The idea for this series was born back from Dublin (ELCE 2022) after
having attended the talk entitled "Updating and Modernizing Clock
Drivers" held by Chen-Yu Tsai and the availability of a board with
imx8mn SOC.

This series aims to setup all imx8mn's clocks from the device tree and
remove the legacy setup code with hardwired parameters.

I am well aware that the series lacks patches for the DT bindings. The
effort up to this point has been important and so I thought I'd ask for
feedback from the community before proceeding to implement them. If it
is positive I will add the DT binding patches starting from version 2.

The series has been tested on the BSH SystemMaster (SMM) S2 board:

Changes in v2:
- Fix compiler warnings reported by kernel test robot.

Dario Binacchi (11):
clk: imx: add structure to extend register accesses
clk: imx: add clk_hw based API imx_get_clk_hw_from_dt()
clk: imx8mn: add gate driver
clk: imx8mn: add mux driver
clk: imx8mn: add divider driver
clk: imx: pll14xx: add device tree support
clk: imx: composite-8m: add device tree support
clk: imx: gate2: add device tree support
clk: imx: cpu: add device tree support
arm64: dts: imx8mn: add dumy clock
arm64: dts: imx8mn: add clocks description
