| * pinctrl: samsung: fix missing GPIOLIB on ARM64 Exynos configKrzysztof Kozlowski2022-04-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB. ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8 Exynos selects only the latter leading to possible wrong configuration on ARMv8 build: WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y]) Selected by [y]: - ARCH_EXYNOS [=y] Always select the GPIOLIB from the Samsung pinctrl drivers to fix the issue. This requires removing of OF_GPIO dependency (to avoid recursive dependency), so add dependency on OF for COMPILE_TEST cases.

Take this opportunity to update some other minor config options: - CONFIG_MARVELL_PHY moved around because of Kconfig changes. - CONFIG_SENSORS_DRIVETEMP should be selected since is regulates the system critical alert temperature on some devices, which is nice if it is handled even if initramfs or root fails to mount.

Based on discussions on the #armlinux irc channel, Arnd noticed that omaps are using __pa() for stack for smc calls. This does not work with vmap stack. Let's fix the issue by changing the param arrays to use static param[5] for each function for __pa() to work. This consumes a bit more memory compared to adding a single static buffer, but avoids potential races with the smc calls initializing the shared buffer. For omap_secure_dispatcher(), we need to use a cpu specific buffer as there's nothing currently ensuring it only gets called from cpu0.

Right now it needs to be explicitly selected by architectures, and is only done so by architectures that require remapping to deal with devices that are not DMA coherent. Make it unconditional for builds with CONFIG_MMU as it is very little extra code, but makes it much more likely that large DMA allocations succeed on x86. This fixes hot plugging a NVMe thunderbolt SSD for me, which tries to allocate a 1MB buffer that is otherwise hard to obtain due to memory fragmentation on a heavily used laptop.
