Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Olof Johansson:
"I've been sitting on these longer than I meant, so the patch count is
a bit higher than ideal for this part of the release. There's also
some reverts of double-applied patches that brings the diffstat up a
bit.
With that said, the biggest changes are:
- Revert of duplicate i2c device addition on two Aspeed (BMC)
Devicetrees.
- Move of two device nodes that got applied to the wrong part of the
tree on ASpeed G6.
- Regulator fix for Beaglebone X15 (adding 12/5V supplies)
- Use interrupts for keys on Amlogic SM1 to avoid missed polls
In addition to that, there is a collection of smaller DT fixes:
- Power supply assignment fixes for i.MX6
- Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit
- Build fixlets (selects) for davinci/omap2+
- More interrupt number fixes for Stratix10, Amlogic SM1, etc.
- ... and more similar fixes across different platforms
And some non-DT stuff:
- optee fix to register multiple shared pages properly
- Clock calculation fixes for MMP3
- Clock fixes for OMAP as well"
