ARM: shmobile: Drop selecting SOC_BUS

2022-09-18T12:51:10Z

Don't automatically select the SOC_BUS config option as we already have automatically selected it as part of the SOC_RENESAS config option [0] as renesas-soc.c [1] uses the APIs provided by SOC_BUS config option.

ARM: shmobile: rcar-gen2: Increase refcount for new reference

2022-07-05T07:08:35Z

In rcar_gen2_regulator_quirk(), for_each_matching_node_and_match() will automatically increase and decrease the refcount. However, we should call of_node_get() for the new reference created in 'quirk->np'. Besides, we also should call of_node_put() before the 'quirk' being freed.

ARM: shmobile: rcar-gen2: Drop comma after OF match table sentinel

2022-05-05T10:32:40Z

It does not make sense to have a comma after a sentinel, as any new elements must be added before the sentinel. Add a comment to clarify the purpose of the empty element.

ARM: remove support for NOMMU ARMv4/v5

2022-03-17T08:13:13Z

It is possible to build MMU-less kernels for Cortex-M base microcrontrollers as well as a couple of older platforms that have not been converted to CONFIG_ARCH_MULTIPLATFORM, specifically ep93xx, footbridge, dove, sa1100 and s3c24xx. It seems unlikely that anybody has tested those configurations in recent years, as even building them is frequently broken. A patch I submitted caused another build time regression in this configuration. I sent a patch for that, but it seems better to also remove the option entirely, leaving ARMv7-M as the only supported Arm NOMMU target for simplicity. A couple of platforms have dependencies on CONFIG_MMU, those can all be removed now. Notably, mach-integrator tries to support MMU-less CPU cores, but those have not actually been selectable for a long time. This addresses several build failures in randconfig builds that have accumulated over the years.

ARM: shmobile: rcar-gen2: Add missing of_node_put()

Fix following coccicheck warning: ./arch/arm/mach-shmobile/regulator-quirk-rcar-gen2.c:156:1-33: Function for_each_matching_node_and_match should have of_node_put() before break and goto.

ARM: shmobile: Stop using __raw_*() I/O accessors

2020-11-23T08:54:59Z

There is no reason to keep on using the __raw_{read,write}l() I/O accessors in Renesas ARM platform code. Switch to using the plain {read,write}l() I/O accessors, to have a chance that this works on big-endian.
