Do the initial setting of the pmic wrap interrupt before requesting the interrupt. This fixes the corner-case where the pmic is initialized by the bootloader, but not the pmic watchdog. Add support for active wakeup to the scpsys. This allows to keep the power of a scpsys domain during suspend state. With version v4.3 new subsystem clocks are added to the clock dirver. In late init the kernel turns off all unused clocks. This can provoke a hang if the kernel tries to access the venc and venc_lt power domain registers. Add the necessary parent clocks for this power domains to the scpsys so that no random hang happens. The bootloader of mt6589, mt8135 and mt1827 does not turn on the arm-arch-timer. As there is no opensource bootloader in the near future for this architectures we enable the arch timer at kernel boot. We need the arch timer for SMP boot. Add support for SMP on mt6589, mt8127 and mt8135. * tag 'v4.3-next-soc' of https://github.com/mbgg/linux-mediatek: ARM: mediatek: add smp bringup code ARM: mediatek: enable gpt6 on boot up to make arch timer working soc: mediatek: Fix random hang up issue while kernel init soc: mediatek: add scpsys support active_wakeup soc: mediatek: Move the initial setting of pmic wrap interrupt before requesting irq.

The R8 is a new Allwinner SoC based on the A13. While both are very similar, there's still a few differences. Introduce a new compatible to deal with them. In order to have a consistent naming, instead of mentioning the Allwinner A series as the machine name, switch to sun4i/sun5i like what is done for the other families.

Add cpu hotplug support for berlin SoCs such as BG2 and BG2Q. These SoC don't support power off cpu independently, but we also want cpu hotplug support in these SoCs.

In kernel late init, it turns off all unused clocks, which needs to access subsystem registers such as VENC and VENC_LT. Accessing MT8173 VENC registers needs two top clocks, mm_sel and venc_sel. Accessing VENC_LT registers needs mm_sel and venclt_sel. So we need to keep these clocks on before accessing their registers. This patch keeps venc_sel / venclt_sel clock on when VENC / VENC_LT's power is on, to prevent system hang up while accessing its registeres.

Currently firmware file name is included in the DTS. This is not scalable as user has to change the DTS if they need upgrade to a new firmware. Instead, add the firmware file name in the driver itself. As long as there is no API change, new firmware upgrade is easy and require no driver change. User is expected to copy the firmware image to the file system and add a sym link to the new firmware for doing an upgrade. Driver add a array of firmware file names to search for the available firmware blobs. This scheme also prepare the driver for future changes to API if ever happens. In such case it is assumed that driver needs to change to accommodate the new firmware and new firmware file name will get added to the array. Also update the DT document to remove the firmware attribute and add description about firmware in the driver documentation.

Pull strscpy string copy function implementation from Chris Metcalf. Chris sent this during the merge window, but I waffled back and forth on the pull request, which is why it's going in only now. The new "strscpy()" function is definitely easier to use and more secure than either strncpy() or strlcpy(), both of which are horrible nasty interfaces that have serious and irredeemable problems. strncpy() has a useless return value, and doesn't NUL-terminate an overlong result. To make matters worse, it pads a short result with zeroes, which is a performance disaster if you have big buffers. strlcpy(), by contrast, is a mis-designed "fix" for strlcpy(), lacking the insane NUL padding, but having a differently broken return value which returns the original length of the source string. Which means that it will read characters past the count from the source buffer, and you have to trust the source to be properly terminated. It also makes error handling fragile, since the test for overflow is unnecessarily subtle. strscpy() avoids both these problems, guaranteeing the NUL termination (but not excessive padding) if the destination size wasn't zero, and making the overflow condition very obvious by returning -E2BIG. It also doesn't read past the size of the source, and can thus be used for untrusted source data too. So why did I waffle about this for so long? Every time we introduce a new-and-improved interface, people start doing these interminable series of trivial conversion patches. And every time that happens, somebody does some silly mistake, and the conversion patch to the improved interface actually makes things worse. Because the patch is mindnumbing and trivial, nobody has the attention span to look at it carefully, and it's usually done over large swatches of source code which means that not every conversion gets tested. So I'm pulling the strscpy() support because it *is* a better interface. But I will refuse to pull mindless conversion patches. Use this in places where it makes sense, but don't do trivial patches to fix things that aren't actually known to be broken. * 'strscpy' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: tile: use global strscpy() rather than private copy string: provide strscpy() Make asm/word-at-a-time.h available on all architectures

The MIPS syscall handler code used to return -ENOSYS on invalid syscalls. Whilst this is expected, it caused problems for seccomp filters because the said filters never had the change to run since the code returned -ENOSYS before triggering them. This caused problems on the chromium testsuite for filters looking for invalid syscalls. This has now changed and the seccomp filters are always run even if the syscall is invalid. We return -ENOSYS once we return from the seccomp filters. Moreover, similar codepaths have been merged in the process which simplifies somewhat the overall syscall code.

When configuring the interrupt mapping for a new device, we iterate over all the possible aliases to account for their maximum MSI allocation. This was introduced by e8137f4f ("irqchip: gicv3-its: Iterate over PCI aliases to generate ITS configuration"). Turns out that the code doing that is a bit braindead, and repeatedly accounts for the same device over and over. Fix this by counting the actual alias that is passed to us by the core code.
