2019-09-23regulator: da9062: fix suspend_enable/disable preparationMarco Felsch
Currently the suspend reg_field maps to the pmic voltage selection bits and is used during suspend_enabe/disable() and during get_mode(). This seems to be wrong for both use cases. Use case one (suspend_enabe/disable): Those callbacks are used to mark a regulator device as enabled/disabled during suspend. Marking the regulator enabled during suspend is done by the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers. Setting this bit tells the DA9062 PMIC state machine to keep the regulator on in POWERDOWN mode and switch to suspend voltage. Use case two (get_mode): The get_mode callback is used to retrieve the active mode state. Since the regulator-setting-A is used for the active state and regulator-setting-B for the suspend state there is no need to check which regulator setting is active.

2019-09-09regulator: slg51000: use devm_gpiod_get_optional() in probeDmitry Torokhov
The CS GPIO line is clearly optional GPIO (and marked as such in the binding document) and we should handle it accordingly. The current code treats all errors as meaning that there is no GPIO defined, which is wrong, as it does not handle deferrals raised by the underlying code properly, nor does it recognize non-existing GPIO from any other initialization error. As far as I can see the only reason the driver, unlike all others, is using OF-specific devm_gpiod_get_from_of_node() so that it can assign a custom label to the selected GPIO line. Given that noone else needs that, it should not be doing that either. Let's switch to using more appropriate devm_gpiod_get_optional().

2019-09-04regulator: Defer init completion for a while after late_initcallMark Brown
The kernel has no way of knowing when we have finished instantiating drivers, between deferred probe and systems that build key drivers as modules we might be doing this long after userspace has booted. This has always been a bit of an issue with regulator_init_complete since it can power off hardware that's not had it's driver loaded which can result in user visible effects, the main case is powering off displays. Practically speaking it's not been an issue in real systems since most systems that use the regulator API are embedded and build in key drivers anyway but with Arm laptops coming on the market it's becoming more of an issue so let's do something about it. In the absence of any better idea just defer the powering off for 30s after late_initcall(), this is obviously a hack but it should mask the issue for now and it's no more arbitrary than late_initcall() itself. Ideally we'd have some heuristics to detect if we're on an affected system and tune or skip the delay appropriately, and there may be some need for a command line option to be added.

2019-08-15regulator: twl: voltage lists for vdd1/2 on twl4030Andreas Kemnade
_opp_supported_by_regulators() wrongly ignored errors from regulator_is_supported_voltage(), so it considered errors as success. Since commit 498209445124 ("regulator: core: simplify return value on suported_voltage") regulator_is_supported_voltage() returns a real boolean, so errors make _opp_supported_by_regulators() return false. That reveals a problem with the declaration of the VDD1/2 regulators on twl4030. The VDD1/VDD2 regulators on twl4030 are neither defined with voltage lists nor with the continuous flag set, so regulator_is_supported_voltage() returns false and an error before above mentioned commit (which was considered success) The result is that after the above mentioned commit cpufreq does not work properly e.g. dm3730. [ 2.490997] core: _opp_supported_by_regulators: OPP minuV: 1012500 maxuV: 1012500, not supported by regulator [ 2.501617] cpu cpu0: _opp_add: OPP not supported by regulators (300000000) [ 2.509246] core: _opp_supported_by_regulators: OPP minuV: 1200000 maxuV: 1200000, not supported by regulator [ 2.519775] cpu cpu0: _opp_add: OPP not supported by regulators (600000000) [ 2.527313] core: _opp_supported_by_regulators: OPP minuV: 1325000 maxuV: 1325000, not supported by regulator [ 2.537750] cpu cpu0: _opp_add: OPP not supported by regulators (800000000) The patch fixes declaration of VDD1/2 regulators by adding proper voltage lists.

2019-08-09regulator: twl6030: workaround the VMMC reset behaviorGregory CLEMENT
During reset the VMMC regulator doesn't reach 0V and only drops to 1.8V, furthermore the pulse width is under 200us whereas the SD specification expect 1ms. The WR_S bit allows the TWL6030 to no reset at all the VMMC during warm reset and keep the current voltage. Thanks to this workaround the SD card doesn't reach a undefined reset stage. Actually this behavior is available for all the LDO regulator, so the driver will also allow to use it with any of these regulator.

Each iteration of for_each_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak.

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

The local variable search in regulator_of_get_init_node takes the value returned by either of_get_child_by_name or of_node_get, both of which get a node.
