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

Message

Abel Vesa April 15, 2020, 8:02 a.m. UTC

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
