Subject: [PATCH v3 00/13] Add generic MFD i.MX mix and audiomix support

The i.MX8MP has some new IPs called mixes. They are formed usually by some
GPRs that can be split into different functionalities. The first example
here is the audiomix which has dedicated registers that can be registered
as a clock controller and some other registers that can be registered as
a reset controller, plus some dedicated ones that will be registered as
syscon and used by each dedicated audio IP.

More mixes to be following the same structure are to come, like hdmimix,
dispmix and mediamix. They will all be populated and registered by the MFD
imx-mix generic driver.

Changes since v2:
 * removed the runtime PM for now
 * changed the new SPDX identifiers to GPL-2.0-only
 * took care of the DT schema comment

  clk: imx: gate2: Allow single bit gating clock
  clk: imx: pll14xx: Add the device as argument when registering
  clk: imx: Add helpers for passing the device as argument
  dt-bindings: clocks: imx8mp: Add ids for audiomix clocks
  clk: imx: Add audiomix clock controller support
  arm64: dts: imx8mp: Add audiomix clock controller node
