| | * | regulator: core: simplify _regulator_get()Dmitry Torokhov2017-02-081-32/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in _regulator_get() got a bit confusing over time, with control flow jumping to a label from couple of places. Let's untangle it a bit by doing the following: 1. Make handling of missing supplies and substituting them with dummy regulators more explicit: - check if we not have full constraints and refuse considering dummy regulators with appropriate message; - use "switch (get_type)" to handle different types of request explicitly as well. "Normal" requests will get dummies, exclusive will not and will notify user about that; optional will fail silently. 2. Stop jumping to a label in the middle of the function but instead have proper conditional flow. I believe jumps should be reserved for error handling, breaking from inner loop, or restarting a loop, but not for implementing normal conditional flow.

| | * | regulator: core: have regulator_dev_lookup() return ERR_PTR-encoded errorsDmitry Torokhov2017-02-051-19/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of returning both regulator_dev structure as return value and auxiliary error code in 'ret' argument, let's switch to using ERR_PTR encoded values. This makes it more obvious what is going on at call sites. Also, let's not unlock the mutex in the middle of a loop, but rather break out and have single unlock path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of separate "exclusive" and "allow_dummy" arguments, that formed 3 valid combinations (normal, exclusive and optional) and an invalid one, let's accept explicit "get_type", like we did in devm-managed code.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no point in assigning value to 'ret' before calling regulator_dev_lookup() as it will clobber 'ret' anyway. Also, let's explicitly return -PROBE_DEFER when try_module_get() fails, instead of relying that earlier initialization of "regulator" carries correct value.

This prevent regulators to hold an invalid reference if its supply parent device driver probe is deferred. But this causes issues on some boards where a PMIC's regulator use as input supply a regulator from another PMIC whose driver is registered after the driver for the former. In this case the regulators for the first PMIC will fail to resolve input supplies on regulators registration (since the other PMIC wasn't probed yet). And when the core attempts to resolve again latter when the other PMIC registers its own regulators, it will fail again since the parent device isn't bound yet. This will cause some parent supplies to never be resolved and wrongly be disabled on boot due taking them as unused. To solve this problem, also attempt to resolve the pending regulators input supplies before disabling the unused regulators.

While there does appear to be a practical need to manage regulators on ACPI systems, using ad-hoc properties to describe regulators to the kernel presents a number of problems (especially should ACPI gain first class support for such things), and there are ongoing discussions as to how to manage this. Until there is a rough consensus, revert commit 13bed58ce8748d43, which hasn't been in a released kernel yet as discussed in [1] and the surrounding thread.

| * | | | regulator: gpio: properly check return value of of_get_named_gpioJisheng Zhang2016-11-111-3/+6
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function of_get_named_gpio() could return -ENOENT, -EPROBE_DEFER -EINVAL and so on. Currently, for the optional property "enable-gpio", we only check -EPROBE_DEFER, this is not enough since there may be misconfigured "enable-gpio" in the DTB, of_get_named_gpio() will return -EINVAL in this case, we should return immediately here. And for the optional property "gpios", we didn't check the return value, the driver will continue to the point where gpio_request_array() is called, it doesn't make sense to continue if we got -EPROBE_DEFER or -EINVAL here. This patch tries to address these two issues by properly checking the return value of of_get_named_gpio.

This results in those drivers reporting bypass being enabled when it is not. In regulator_set_bypass_regmap we use bypass_mask if bypass_val_on is zero. This patch adds similar handling in regulator_get_bypass_regmap.
