2017-02-08regulator: core: simplify _regulator_get()Dmitry Torokhov
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.

2017-02-05regulator: core: have regulator_dev_lookup() return ERR_PTR-encoded errorsDmitry Torokhov
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.

2017-02-04regulator: cpcap: Add basic regulator supportTony Lindgren
Many Motorola phones like droid 4 are using a custom PMIC called CPCAP or 6556002. This PMIC is used with several SoCs, I've noticed at least omap3, omap4 and Tegra2 based Motorola phones and tablets using it.

2017-02-04regulator: core: optimize devm_regulator_bulk_get()Dmitry Torokhov
When performing this bulk operation, there is no need to track every supply individually. It is more efficient to treat entire group as a single managed resource. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>

There is no need to have two loops there, we can store error for subsequent reporting. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-02-04regulator: core: have _regulator_get() accept get_type argumentDmitry Torokhov
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.

2017-02-04regulator: core: remove dead code in _regulator_get()Dmitry Torokhov
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.

2017-01-26regulator: s2mpa01: reduce stack size for probe functionArnd Bergmann
In some rare configurations we can run into rather high kernel stack consumption: drivers/regulator/s2mpa01.c:397:1: error: the frame size of 1536 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] This is probably harmless since it happens only in the probe function, but there is also a relatively simple workaround, moving the regulator match data into the device specific structure. As a small downside, we waste a little memory at runtime. An alternative approach would free the array at the end of the probe function, which in turn is a little more complicated.

2017-01-25regulator: fixed: Revert support for ACPI interfaceMark Rutland
This reverts commit 13bed58ce874 (regulator: fixed: add support for ACPI interface). 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.
