Pull ARM SoC updates from Arnd Bergmann: "There are three noteworthy updates for 32-bit arm platforms this time: - The Microchip SAMA7 family based on Cortex-A7 gets introduced, a new cousin to the older SAM9 (ARM9xx based) and SAMA5 (Cortex-A5 based) SoCs. - The ixp4xx platform (based on Intel XScale) is finally converted to device tree, and all the old board files are getting removed now. - The Cirrus Logic EP93xx platform loses support for the old MaverickCrunch FPU. Support for compiling user space applications was already removed in gcc-4.9, and the kernel support for old applications could not be built with clang ias. After confirming that there are no remaining users, removing this from the kernel seemed better than adding support for unused features to clang. There are minor updates to the aspeed, omap and samsung platforms" * tag 'soc-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (48 commits) soc: aspeed-lpc-ctrl: Fix clock cleanup in error path ARM: s3c: delete unneed local variable "delay" soc: aspeed: Re-enable FWH2AHB on AST2600 soc: aspeed: socinfo: Add AST2625 variant soc: aspeed: p2a-ctrl: Fix boundary check for mmap soc: aspeed: lpc-ctrl: Fix boundary check for mmap ARM: ixp4xx: Delete the Freecom FSG-3 boardfiles ARM: ixp4xx: Delete GTWX5715 board files ARM: ixp4xx: Delete Coyote and IXDPG425 boardfiles ARM: ixp4xx: Delete Intel reference design boardfiles ARM: ixp4xx: Delete Avila boardfiles ARM: ixp4xx: Delete the Arcom Vulcan boardfiles ARM: ixp4xx: Delete Gateway WG302v2 boardfiles ARM: ixp4xx: Delete Omicron boardfiles ARM: ixp4xx: Delete the D-Link DSM-G600 boardfiles ARM: ixp4xx: Delete NAS100D boardfiles ARM: ixp4xx: Delete NSLU2 boardfiles arm: omap2: Drop the unused OMAP_PACKAGE_* KConfig entries arm: omap2: Drop obsolete MACH_OMAP3_PANDORA entry ARM: ep93xx: remove MaverickCrunch support ...

2021-04-01ARM: s3c: Use pwm_get() in favour of pwm_request() in RX1950Uwe Kleine-König1-5/+6
pwm_request() is deprecated because (among others) it depends on a global numbering of PWM devices. So register a pwm_lookup to pick the right PWM device (identified by provider and its local id) and use pwm_get(). Before this patch the PWM #1 was used. This is provided by the samsung-pwm device which is the only PWM provider on this machine. The local offset is 1, see also commit c107fe904a10 ("ARM: S3C24XX: Use PWM lookup table for mach-rx1950") with a similar conversion for PWM #0. As a follow up specify the period only once and symmetrically use pwm_put() instead of pwm_free() to drop the reference.

2020-08-28ARM: s3c: Avoid naming clash of S3C24xx and S3C64xx timer setupKrzysztof Kozlowski38-89/+89
PWM timer initialization has two independent implementations - one for S3C24xx and one for S3C64xx. The naming however was always the same and before also the declaration was shared.
