Merge tag 'arm-multiplatform-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull more ARM multiplatform updates from Arnd Bergmann:
"The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went
through several rebases before the merge window as bugs were found, so
they remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files"
