2022-06-01regulator: mt6315-regulator: fix invalid allowed modeFabien Parent1-2/+2
In the binding example, the regulator mode 4 is shown as a valid mode, but the driver actually only support mode 0 to 2: This generates an error in dmesg when copy/pasting the binding example: [ 0.306080] vbuck1: invalid regulator-allowed-modes element 4 [ 0.307290] vbuck2: invalid regulator-allowed-modes element 4 This commit fixes this error by removing the invalid mode from the examples.

The RPMH regulator binding covers several devices with different regulator supplies, so it uses patterns matching broad range of these supplies.

2022-04-25regulator: dt-bindings: richtek,rt4801: use existing ena_gpiod featureKrzysztof Kozlowski1-1/+13
The binding and driver duplicated regulator core feature of controlling regulators with GPIOs (of_parse_cb + ena_gpiod) and created its own enable-gpios property with multiple GPIOs. This is a less preferred way, because enable-gpios should enable only one element, not multiple. It also duplicates existing solution. Deprecate the original 'enable-gpios' and add per-regulator property.

2022-04-21regulator: core: Sleep (not delay) in set_voltage()Brian Norris1-6/+1
These delays can be relatively large (e.g., hundreds of microseconds to several milliseconds on RK3399 Gru systems). Per Documentation/timers/timers-howto.rst, that should usually use a sleeping delay. Let's use the existing regulator delay helper to handle both large and small delays appropriately. This avoids burning a bunch of CPU time and hurting scheduling latencies when hitting regulators a lot (e.g., during cpufreq). The sleep vs. delay issue choice has been made differently over time -- early versions of RK3399 Gru PWM-regulator support used usleep_range() in pwm-regulator.c. More of this got moved into the regulator core, in commits like: 73e705bf81ce regulator: core: Add set_voltage_time op At the same time, the sleep turned into a delay. It's OK to sleep in _regulator_do_set_voltage(), as we aren't in an atomic context. (All our callers grab various mutexes already.) I avoid using fsleep() because it uses a usleep_range() of [N to N*2], and usleep_range() very commonly biases to the high end of the range. We don't want to double the expected delay, especially for long delays.

Add a selftest which validates that. - Unroll string MMIO for encrypted SEV guests as the hypervisor cannot emulate it. - Handle supervisor states correctly in the FPU/XSTATE code so it takes the feature set of the fpstate buffer into account. The feature sets can differ between host and guest buffers. Guest buffers do not contain supervisor states. So far this was not an issue, but with enabling PASID it needs to be handled in the buffer offset calculation and in the permission bitmaps. - Avoid a gazillion of repeated CPUID invocations in by caching the values early in the FPU/XSTATE code. - Enable CONFIG_WERROR in x86 defconfig. - Make the X86 defconfigs more useful by adapting them to Y2022 reality" * tag 'x86-urgent-2022-04-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fpu/xstate: Consolidate size calculations x86/fpu/xstate: Handle supervisor states in XSTATE permissions x86/fpu/xsave: Handle compacted offsets correctly with supervisor states x86/fpu: Cache xfeature flags from CPUID x86/fpu/xsave: Initialize offset/size cache early x86/fpu: Remove unused supervisor only offsets x86/fpu: Remove redundant XCOMP_BV initialization x86/sev: Unroll string mmio with CC_ATTR_GUEST_UNROLL_STRING_IO x86/config: Make the x86 defconfigs a bit more usable x86/defconfig: Enable WERROR selftests/x86/amx: Update the ARCH_REQ_XCOMP_PERM test x86/fpu/xstate: Fix the ARCH_REQ_XCOMP_PERM implementation

2022-04-03Revert "clk: Drop the rate range on clk_put()"Stephen Boyd2-136/+14
This reverts commit 7dabfa2bc4803eed83d6f22bd6f045495f40636b. There are multiple reports that this breaks boot on various systems. The common theme is that orphan clks are having rates set on them when that isn't expected. Let's revert it out for now so that -rc1 boots.
