* regulator: MAX20086: add gpio/consumer.hRandy Dunlap2022-01-191-0/+1

* regulator: qcom_smd: Align probe function with rpmh-regulatorKonrad Dybcio2022-01-061-30/+70
| | | | | | | | | | | | | | | | | | | | | | | The RPMh regulator driver is much newer and gets more attention, which in consequence makes it do a few things better. Update qcom_smd-regulator's probe function to mimic what rpmh-regulator does to address a couple of issues: - Probe defer now works correctly, before it used to, well, kinda just die.. This fixes reliable probing on (at least) PM8994, because Linux apparently cannot deal with supply map dependencies yet.. - Regulator data is now matched more sanely: regulator data is matched against each individual regulator node name and throwing an -EINVAL if data is missing, instead of just assuming everything is fine and iterating over all subsequent array members. - status = "disabled" will now work for disabling individual regulators in DT. Previously it didn't seem to do much if anything at all.

* regulator: Introduce tps68470-regulator driverHans de Goede2021-12-153-0/+211
| | | | | | | | | | | | | | | | | | | | | The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in the kernel the Regulators and Clocks are controlled by an OpRegion driver designed to work with power control methods defined in ACPI, but some platforms lack those methods, meaning drivers need to be able to consume the resources of these chips through the usual frameworks. This commit adds a driver for the regulators provided by the tps68470, and is designed to bind to the platform_device registered by the intel_skl_int3472 module. This is based on this out of tree driver written by Intel: https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/regulator/tps68470-regulator.c with various cleanups added.

Add Stephen's and Rob's tags. 2. Correct inb-supply description in patch 10/10. Changes since v2 ================ 1. Add Rob's tags. 2. Remove "regulator-name" from properties (all regulator dtschema). 3. Move "unevaluatedProperties" higher to make code easier to read (all regulator dtschema). 4. Add ref-type to op-mode property (patch 6: s5m8767 regulators). Changes since v1 ================ 1. Drop DTS patches - applied. 2. Fully remove bindings/regulator/samsung,s5m8767.txt . 3. Minor subject reformatting and few typos in text. Intro ===== This patchset converts all devicetree bindings of Samsung S2M and S5M PMIC devices from txt to dtschema. It includes also two fixes because later conversion depends on it (contextually). Merging/dependencies ==================== 1. Regulator related binding changes depend on first two commits (the fixes), because of context. 2. The mfd bindings depend on clock and regulator bindings. The fixes and bindings changes (patches 1-10) should go via the same tree. For example regulator or mfd tree. Another alternative is that regulator patches (1-2, 4-6) go via Mark who later gives MFD a stable branch/tag to pull. Then the clock and MFD bindings would go on top via MFD tree. Or any other setup you would like to have. Overview of devices =================== Essentially all Samsung S2M and S5M PMICs are very similar devices. They provide the same functionality: regulators, RTC, 2 or 3 clocks and main power management (e.g. power cut to SoC). The differences are mostly in registers layout and number of regulators. The drivers are built around one common part, mfd/sec-core.c, and share some drivers between devices: 1. MFD sec-core for all devices, 1. one clock driver for most of devices, 2. one RTC driver for all devices, 3. three regulator drivers. The regulator drivers were implementing slightly different features, therefore one regulator binding for all devices does not make much sense. However the clock device binding can be shared. The final dtschema bindings try to implement this - share only the clock bindings.

IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

All off and both are sequentially controlled to be on. The 'enable' gpio control block to be called twice including the delay time. 2. Both are on and one is preparing to be off. The 'enable' gpio control low before register cache is configured to be true.

Our caller already attempts to resolve supplies and retry, so we shouldn't be printing this error to logs.

In this case, the support of COMPILE_TEST is added, so this module could be compiled in other platform(e.g.X86), without ARCH_SYNQUACER configuration.

The main use case is emulating Windows' WaitForMultipleObjects which allows Wine to improve the performance of Windows Games. Also native Linux games can benefit from this interface as this is a common wait pattern for this kind of applications. - Add context to ww_mutex_trylock() to provide a path for i915 to rework their eviction code step by step without making lockdep upset until the final steps of rework are completed. It's also useful for regulator and TTM to avoid dropping locks in the non contended path. - Lockdep and might_sleep() cleanups and improvements - A few improvements for the RT substitutions. - The usual small improvements and cleanups. * tag 'locking-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits) locking: Remove spin_lock_flags() etc locking/rwsem: Fix comments about reader optimistic lock stealing conditions locking: Remove rcu_read_{,un}lock() for preempt_{dis,en}able() locking/rwsem: Disable preemption for spinning region docs: futex: Fix kernel-doc references futex: Fix PREEMPT_RT build futex2: Documentation: Document sys_futex_waitv() uAPI selftests: futex: Test sys_futex_waitv() wouldblock selftests: futex: Test sys_futex_waitv() timeout selftests: futex: Add sys_futex_waitv() test futex,arm: Wire up sys_futex_waitv() futex,x86: Wire up sys_futex_waitv() futex: Implement sys_futex_waitv() futex: Simplify double_lock_hb() futex: Split out wait/wake futex: Split out requeue futex: Rename mark_wake_futex() futex: Rename: match_futex() futex: Rename: hb_waiter_{inc,dec,pending}() futex: Split out PI futex ...
