Merge tag 'arm-boardfile-remove-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC boardfile updates from Arnd Bergmann "Unused boardfile removal for 6.3 This is a follow-up to the deprecation of most of the old-style board files that was merged in linux-6.0, removing them for good. This branch is almost exclusively dead code removal based on those annotations. Some device driver removals went through separate subsystem trees, but the majority is in the same branch, in order to better handle dependencies between the patches and avoid breaking bisection. Unfortunately that leads to merge conflicts against other changes in the subsystem trees, but they should all be trivial to resolve by removing the files. See commit 7d0d3fa7339e ("Merge tag 'arm-boardfiles-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the description of which machines were marked unused and are now removed. The only removals that got postponed are Terastation WXL (mv78xx0) and Jornada720 (StrongARM1100), which turned out to still have potential users" * tag 'arm-boardfile-remove-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (91 commits) mmc: omap: drop TPS65010 dependency ARM: pxa: restore mfp-pxa320.h usb: ohci-omap: avoid unused-variable warning ARM: debug: remove references in DEBUG_UART_8250_SHIFT to removed configs ARM: s3c: remove obsolete s3c-cpu-freq header MAINTAINERS: adjust SAMSUNG SOC CLOCK DRIVERS after s3c24xx support removal MAINTAINERS: update file entries after arm multi-platform rework and mach-pxa removal ARM: remove CONFIG_UNUSED_BOARD_FILES mfd: remove htc-pasic3 driver w1: remove ds1wm driver usb: remove ohci-tmio driver fbdev: remove w100fb driver fbdev: remove tmiofb driver mmc: remove tmio_mmc driver mfd: remove ucb1400 support mfd: remove toshiba tmio drivers rtc: remove v3020 driver power: remove pda_power supply driver ASoC: pxa: remove unused board support pcmcia: remove unused pxa/sa1100 drivers ...
