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" * tag 'arm-multiplatform-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (48 commits) ARM: pxa/mmp: remove traces of plat-pxa ARM: pxa: convert to multiplatform ARM: pxa/sa1100: move I/O space to PCI_IOBASE ARM: pxa: remove support for MTD_XIP ARM: pxa: move mach/*.h to mach-pxa/ ARM: PXA: fix multi-cpu build of xsc3 ARM: pxa: move plat-pxa to drivers/soc/ ARM: mmp: rename pxa_register_device ARM: mmp: remove tavorevb board support ARM: pxa: remove unused mach/bitfield.h ARM: pxa: move clk register definitions to driver ARM: pxa: move smemc register access from clk to platform cpufreq: pxa3: move clk register access to clk driver ARM: pxa: remove get_clk_frequency_khz() ARM: pxa: pcmcia: move smemc configuration back to arch ASoC: pxa: i2s: use normal MMIO accessors ASoC: pxa: ac97: use normal MMIO accessors ASoC: pxa: use pdev resource for FIFO regs Input: wm97xx - get rid of irq_enable method in wm97xx_mach_ops Input: wm97xx - switch to using threaded IRQ ...
