This adds support for the MediaTek MT6359 PMIC. This is a multifunction device with the following sub modules: - Codec - Interrupt - Regulator - RTC It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap.

2021-06-01Revert "fb_defio: Remove custom address_space_operations"Matthew Wilcox
Commit ccf953d8f3d6 makes framebuffers which use deferred I/O stop displaying updates after the first one. This is because the pages handled by fb_defio no longer have a page_mapping(). That prevents page_mkclean() from marking the PTEs as clean, and so writes are only noticed the first time.

2021-06-01kprobes: Remove kprobe::fault_handlerPeter Zijlstra
The reason for kprobe::fault_handler(), as given by their comment: * We come here because instructions in the pre/post * handler caused the page_fault, this could happen * if handler tries to access user space by * copy_from_user(), get_user() etc. Let the * user-specified handler try to fix it first. Is just plain bad. Those other handlers are ran from non-preemptible context and had better use _nofault() functions. Also, there is no upstream usage of this.

2021-06-01KVM: arm64: vgic: Let an interrupt controller advertise lack of HW deactivationMarc Zyngier
The vGIC, as architected by ARM, allows a virtual interrupt to trigger the deactivation of a physical interrupt. This allows the following interrupt to be delivered without requiring an exit. However, some implementations have choosen not to implement this, meaning that we will need some unsavoury workarounds to deal with this. On detecting such a case, taint the kernel and spit a nastygram. We'll deal with this in later patches. Signed-off-by: Marc Zyngier <maz@kernel.org>
2021-06-01KVM: arm64: vgic: Be tolerant to the lack of maintenance interrupt maskingMarc Zyngier
As it turns out, not all the interrupt controllers are able to expose a vGIC maintenance interrupt that can be independently enabled/disabled. And to be fair, it doesn't really matter as all we require is for the interrupt to kick us out of guest mode out way or another. To that effect, add gic_kvm_info.no_maint_irq_mask for an interrupt controller to advertise the lack of masking. Signed-off-by: Marc Zyngier <maz@kernel.org>
2021-06-01irqchip/gic: Split vGIC probing information from the GIC codeMarc Zyngier
The vGIC advertising code is unsurprisingly very much tied to the GIC implementations. However, we are about to extend the support to lesser implementations. Let's dissociate the vgic registration from the GIC code and move it into KVM, where it makes a bit more sense. This also allows us to mark the gic_kvm_info structures as __initdata.

2021-05-27driver core: Drop helper devm_platform_ioremap_resource_wc()Uwe Kleine-König
Since the macro was introduced in 2019 (commit bb6243b4f73d ("drivers: platform: provide devm_platform_ioremap_resource_wc()") there is only a single user which hardly justifies the function for the small task it provides. So drop the helper and open-code it in the only user. Adapt the non-wc case accordingly. For a all-mod-config build on amd64 this change introduces the following changes according to bloat-o-meter: add/remove: 0/1 grow/shrink: 1/0 up/down: 20/-252 (-232) Function old new delta devm_platform_ioremap_resource_wc 252 - -252 sram_probe 796 816 +20 Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Link: https://lore.kernel.org/r/20210525103711.956438-1-u.kleine-koenig@pengutronix.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-05-27random32: Fix implicit truncation warning in prandom_seed_state()Richard Fitzgerald
sparse generates the following warning: include/linux/prandom.h:114:45: sparse: sparse: cast truncates bits from constant value This is because the 64-bit seed value is manipulated and then placed in a u32, causing an implicit cast and truncation. A forced cast to u32 doesn't prevent this warning, which is reasonable because a typecast doesn't prove that truncation was expected. Logical-AND the value with 0xffffffff to make explicit that truncation to 32-bit is intended.
