2025-03-12dt-bindings: mmc: sunxi: Simplify compatible string listingAndre Przywara
New Allwinner SoCs only occasionally update their MMC IP, leading to many pairs of compatible strings, though there are sometimes a number of them being compatible with one particular SoC. Collate the compatible string listing in the binding, to group those being compatible together. This makes the list more readable, and allows for easier addition of new SoC's MMC devices.

2025-03-12mmc: renesas_sdhi: Add support for RZ/G3E SoCBiju Das
The SDHI/eMMC IPs in the RZ/G3E SoC are similar to those in R-Car Gen3. However, the RZ/G3E SD0 channel has Voltage level control and PWEN pin support via SD_STATUS register. internal regulator support is added to control the voltage levels of the SD pins via sd_iovs/sd_pwen bits in SD_STATUS register by populating vqmmc-regulator child node. SD1 and SD2 channels have gpio regulator support and internal regulator support. Selection of the regulator is based on the regulator phandle. Similar case for SD0 fixed voltage (eMMC) that uses fixed regulator and SD0 non-fixed voltage (SD0) that uses internal regulator.

2025-03-12dt-bindings: mmc: renesas,sdhi: Document RZ/G3E supportBiju Das
The SD/MMC block on the RZ/G3E ("R9A09G047") SoC is similar to that of the RZ/V2H, but the SD0 channel has only dedicated pins, so we must use SD_STATUS register to control voltage and power enable (internal regulator), for non-fixed voltage (SD) MMC interface. However, it is optional for fixed voltage MMC interface (eMMC). For SD1 and SD2 channels, we can either use gpio regulator or internal regulator (using SD_STATUS register) for voltage switching. Document RZ/G3E SDHI IP support with optional internal regulator for both RZ/G3E and RZ/V2H SoC.

2025-03-12mmc: core: Trim trailing whitespace from card product namesDragan Simic
Product names for some eMMC chips can include trailing whitespace, which seems to be rather uncommon, but makes emitted messages and /sys properties somewhat unsightly. Here's such an example from a Pine64 PineNote, in which "Biwin ", as the eMMC product name, contains trailing whitespace: mmc0: new HS200 MMC card at address 0001 mmcblk0: mmc0:0001 Biwin 115 GiB mmcblk0: p1 p2 p3 p4 p5 p6 p7 mmcblk0boot0: mmc0:0001 Biwin 4.00 MiB mmcblk0boot1: mmc0:0001 Biwin 4.00 MiB mmcblk0rpmb: mmc0:0001 Biwin 4.00 MiB, chardev (249:0) Trailing whitespace in /sys properties may even cause some unforeseen issues with some scripts, so let's have the trailing whitespace trimmed in product names for eMMC chips. Although not observed yet by the author of these changes, the same trailing whitespace may appear in SD card product names, so let's trim them as well, which can't hurt. Touch-up one comment as well, by using proper capitalization.

The compatible property is required for some vendor-specific device trees, such as Amlogic's meson-mx-sdio, but is unnecessary for others, like Microchip's DTS. To resolve unintended warnings for configurations that do not require it, remove compatible from the required properties in mmc-slot.yaml.

Size of physical address space of VM is the same with the size of virtual user space (a half) of physical machine. Variable cpu_vabits represents user address space, kernel address space is not included (user space and kernel space are both a half of total). Here cpu_vabits, rather than cpu_vabits - 1, is to represent the size of guest physical address space. Also there is strict checking about page fault GPA address, inject error if it is larger than maximum GPA address of VM.

2025-03-08LoongArch: KVM: Reload guest CSR registers after sleepBibo Mao
On host, the HW guest CSR registers are lost after suspend and resume operation. Since last_vcpu of boot CPU still records latest vCPU pointer so that the guest CSR register skips to reload when boot CPU resumes and vCPU is scheduled. Here last_vcpu is cleared so that guest CSR registers will reload from scheduled vCPU context after suspend and resume.

There is a newly added macro INT_AVEC with CSR ESTAT register, which is bit 14 used for LoongArch AVEC support. AVEC interrupt status bit 14 is supported with macro CSR_ESTAT_IS, so here replace the hard-coded value 0x1fff with macro CSR_ESTAT_IS so that the AVEC interrupt status is also supported by KVM.

2025-03-08LoongArch: Use polling play_dead() when resuming from hibernationHuacai Chen
When CONFIG_RANDOM_KMALLOC_CACHES or other randomization infrastructrue enabled, the idle_task's stack may different between the booting kernel and target kernel. So when resuming from hibernation, an ACTION_BOOT_CPU IPI wakeup the idle instruction in arch_cpu_idle_dead() and jump to the interrupt handler. But since the stack pointer is changed, the interrupt handler cannot restore correct context. So rename the current arch_cpu_idle_dead() to idle_play_dead(), make it as the default version of play_dead(), and the new arch_cpu_idle_dead() call play_dead() directly. For hibernation, implement an arch-specific hibernate_resume_nonboot_cpu_disable() to use the polling version (idle instruction is replace by nop, and irq is disabled) of play_dead(), i.e. poll_play_dead(), to avoid IPI handler corrupting the idle_task's stack when resuming from hibernation. This solution is a little similar to commit 406f992e4a372dafbe3c ("x86 / hibernate: Use hlt_play_dead() when resuming from hibernation").
