2019-10-21ARM: OMAP2+: Drop legacy platform data for am4 hdq1wTony Lindgren
We can now probe devices with ti-sysc interconnect driver and dts data. Let's drop the related platform data and custom ti,hwmods dts property. As we're just dropping data, and the early platform data init is based on the custom ti,hwmods property, we want to drop both the platform data and ti,hwmods property in a single patch.

2019-10-21KVM: arm64: Support stolen time reporting via shared structureSteven Price
Implement the service call for configuring a shared structure between a VCPU and the hypervisor in which the hypervisor can write the time stolen from the VCPU's execution time by other tasks on the host. User space allocates memory which is placed at an IPA also chosen by user space. The hypervisor then updates the shared structure using kvm_put_guest() to ensure single copy atomicity of the 64-bit value reporting the stolen time in nanoseconds. Whenever stolen time is enabled by the guest, the stolen time counter is reset. The stolen time itself is retrieved from the sched_info structure maintained by the Linux scheduler code. We enable SCHEDSTATS when selecting KVM Kconfig to ensure this value is meaningful. Signed-off-by: Steven Price <steven.price@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

2019-10-21KVM: arm/arm64: Allow user injection of external data abortsChristoffer Dall
In some scenarios, such as buggy guest or incorrect configuration of the VMM and firmware description data, userspace will detect a memory access to a portion of the IPA, which is not mapped to any MMIO region. For this purpose, the appropriate action is to inject an external abort to the guest. The kernel already has functionality to inject an external abort, but we need to wire up a signal from user space that lets user space tell the kernel to do this. It turns out, we already have the set event functionality which we can perfectly reuse for this.

2019-10-21KVM: arm/arm64: Allow reporting non-ISV data aborts to userspaceChristoffer Dall
For a long time, if a guest accessed memory outside of a memslot using any of the load/store instructions in the architecture which doesn't supply decoding information in the ESR_EL2 (the ISV bit is not set), the kernel would print the following message and terminate the VM as a result of returning -ENOSYS to userspace: load/store instruction decoding not implemented The reason behind this message is that KVM assumes that all accesses outside a memslot is an MMIO access which should be handled by userspace, and we originally expected to eventually implement some sort of decoding of load/store instructions where the ISV bit was not set. However, it turns out that many of the instructions which don't provide decoding information on abort are not safe to use for MMIO accesses, and the remaining few that would potentially make sense to use on MMIO accesses, such as those with register writeback, are not used in practice. It also turns out that fetching an instruction from guest memory can be a pretty horrible affair, involving stopping all CPUs on SMP systems, handling multiple corner cases of address translation in software, and more. It doesn't appear likely that we'll ever implement this in the kernel. What is much more common is that a user has misconfigured his/her guest and is actually not accessing an MMIO region, but just hitting some random hole in the IPA space. In this scenario, the error message above is almost misleading and has led to a great deal of confusion over the years. It is, nevertheless, ABI to userspace, and we therefore need to introduce a new capability that userspace explicitly enables to change behavior. This patch introduces KVM_CAP_ARM_NISV_TO_USER (NISV meaning Non-ISV) which does exactly that, and introduces a new exit reason to report the event to userspace. User space can then emulate an exception to the guest, restart the guest, suspend the guest, or take any other appropriate action as per the policy of the running system.

2019-10-21ARM: 8926/1: v7m: remove register save to stack before svcafzal mohammed
r0-r3 & r12 registers are saved & restored, before & after svc respectively. Intention was to preserve those registers across thread to handler mode switch. On v7-M, hardware saves the register context upon exception in AAPCS complaint way. Restoring r0-r3 & r12 is done from stack location where hardware saves it, not from the location on stack where these registers were saved. To clarify, on stm32f429 discovery board: 1. before svc, sp - 0x90009ff8 2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b 3. upon svc, h/w decrements sp by 32 & pushes registers onto stack 4. after svc, sp - 0x90009fd8 5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb Above means r0-r3,r12 is not restored from the location where they are saved, but since hardware pushes the registers onto stack, the registers are restored correctly. Note that during register saving to stack (step 2), it goes past 0x9000a000. And it seems, based on objdump, there are global symbols residing there, and it perhaps can cause issues on a non-XIP Kernel (on XIP, data section is setup later). Based on the analysis above, manually saving registers onto stack is at best no-op and at worst can cause data section corruption. Hence remove storing of registers onto stack before svc.

2019-10-20power: supply: cpcap-charger: Limit voltage to 4.2V for batteryTony Lindgren
There have been some cases of droid4 battery bulging that seem to be related to being left connected to the charger for several weeks. It is suspected that the 4.35V charge voltage configured for the battery is too much in the long run, so lets limit the charge voltage to 4.2V. It could also be that the batteries are just getting old. We don't really want to just change the charge voltage to 4.2V as Android may have charged the battery to 4.35V as pointed out by Pavel Machek. To add checks for battery voltage, the driver needs to understand the voltage it's charging at, and also needs to better understand it's charger state. Right now it only understands connect and disconnect, while now we need to know also a connected state but not charging. So let's add better charger state handling with help of chrgcurr2 interrupt for detecting charge full and retry, and add a check for battery voltage before we start charging. And then we finally can lower the charge voltage to 4.2V. Note that we've been using the same register values as the Android distros on droid4, so it is suspected that the same problem also exists in Android.

2019-10-18ARM: OMAP2+: Configure voltage controller for cpcap to low-speedTony Lindgren
Looks like the i2c timings in high-speed mode do not work properly to allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the device reboots if I2C_DISABLE bits are cleared. Let's configure the voltage controller i2c for low-speed mode as done in the Motorola Mapphone Android Linux kernel. This saves us about 7mW of power during retention compared to the high-speed values. Let's also change the low-speed warning to pr_info about relying on the bootloader configured low-speed values like we currently do.

2019-10-18ARM: dts: bcm2837-rpi-cm3: Avoid leds-gpio probing issueStefan Wahren
bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available on all Raspberry Pi boards. But there is no driver for this particual GPIO on CM3 in mainline yet, so this node was left incomplete without the actual GPIO definition. Since commit 025bf37725f1 ("gpio: Fix return value mismatch of function gpiod_get_from_of_node()") this causing probe issues of the leds-gpio driver for users of the CM3 dtsi file. leds-gpio: probe of leds failed with error -2 Until we have the necessary GPIO driver hide the ACT node for CM3 to avoid this.

There is no need to keep a pointer to the platform device. Currently there are no users of it directly, and if there will be in the future we may restore it from pointer to the struct device.

2019-10-18ARM: OMAP2+: Add pdata for OMAP3 ISP IOMMUSuman Anna
The OMAP3 ISP IOMMU does not have any reset lines, so it didn't need any pdata previously. The OMAP IOMMU driver now requires the platform data ops for device_enable/idle on all the IOMMU devices after commit db8918f61d51 ("iommu/omap: streamline enable/disable through runtime pm callbacks") to enable/disable the clocks properly and maintain the reference count and the omap_hwmod state machine. So, add these callbacks through iommu pdata quirks for the OMAP3 ISP IOMMU. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
