* regulator: mc13xxx: Use lowercase regulator names to match the DTRob Herring2019-01-251-32/+32
| | | | | | | | | | | | | | | | | | | | | | | Since c32569e358ad ("regulator: Use of_node_name_eq for node name comparisons") Vivien reported the mc13892-regulator complaining about not being able to find regulators. This is because prior to that commit we used of_node_cmp() to compare the regulator array passed from mc13892_regulators down to mc13xxx_parse_regulators_dt() and they are all defined in uppercase letters by the MC13892_*_DEFINE* macros, whereas they are defined as lowercase in the DTS. Fix this by using a lowercase regulator name to match the DT node name.

We gained support for runtime mode changes thanks to David Collins and improved support for write only regulators (ones where we can't read back the configuration) from Douglas Anderson. There's been quite a bit of work from Linus Walleij on converting from specfying GPIOs by numbers to descriptors. Sadly the testing turned out to be less good than we had hoped and so a lot of this had to be reverted. We also have the start of updates to use coupled regulators from Maciej Purski, unfortunately there are further problems there so the last couple of patches have been reverted. We also have new drivers for BD71837 and SY8106A devices, SAW regulators on Qualcomm SPMI and dropped support for some preproduction chips that never made it to market from the AB8500 driver" * tag 'regulator-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (57 commits) regulator: gpio: Revert ARM: pxa, regulator: fix building ezx e680 regulator: Revert coupled regulator support again regulator: wm8994: Fix shared GPIOs regulator: max77686: Fix shared GPIOs regulator: bd71837: BD71837 PMIC regulator driver regulator: bd71837: Devicetree bindings for BD71837 regulators regulator: gpio: Get enable GPIO using GPIO descriptor regulator: fixed: Convert to use GPIO descriptor only regulator: s2mps11: Fix boot on Odroid XU3 dt-bindings: qcom_spmi: Document SAW support regulator: qcom_spmi: Add support for SAW regulator: tps65090: Pass descriptor instead of GPIO number regulator: s5m8767: Pass descriptor instead of GPIO number regulator: pfuze100: Delete reference to ena_gpio regulator: max8952: Pass descriptor instead of GPIO number regulator: lp8788-ldo: Pass descriptor instead of GPIO number regulator: lm363x: Pass descriptor instead of GPIO number regulator: max8973: Pass descriptor instead of GPIO number regulator: mc13xxx-core: Switch to SPDX identifier ...

* regulator: mc13892: sanity check num_regulators parsed vs. registeredMatt Sealey2013-01-271-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Imagine a situation where a device tree has a few regulators in an appropriate node: regulators { sw1 { .. }; vvideo { .. }; : vfake { .. }; vtypo { .. }; }; In the above example, the node name "vfake" is an attempt to match a regulator name inside the driver which just so happens to not exist. The node name "vtypo" represents an accidental typographical error in a regulator name which may have been introduced to a device tree. In these cases, the number of regulators the mc13892 driver thinks it has does not match the number of regulators it parsed and registered. Since it will go over this array based on this number, it will actually re-register regulator "0" (which happens to be SW1) over and over again until it reaches the number, resulting in messages on the kernel log such as these: SW1: at 1100 mV VVIDEO: at 2775mV : SW1: at 1100 mV SW1: at 1100 mV .. up to that number of "mismatched" regulators. Nobody using DT can/will consume these regulators, so it should not be possible for it to cause any real regulator problems or driver breakages, but it is an easy thing to miss in a kernel log and is an immediate indication of a problem with the device tree authoring. This patch effectively sanity checks the number of counted children of the regulators node vs. the number that actually matched driver names, and sets the appropriate num_regulators value. It also gives a little warning for device tree authors that they MAY have screwed something up, such that this patch does not hide the device tree authoring problem.

* regulator: mc13892-regulator: correct/refine handling of the SWxHI bitMatt Sealey2013-01-271-16/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MC13892 PMIC supports a "HI" bit for 3 of it's 4 buck switcher outputs, which enables a higher set of voltage ranges. Despite a comment in the code ('sw regulators need special care due to the "hi" bit'), it actually does not take special care since it does not modify it's use of the selector table index when this bit is set, giving us very odd behavior when setting a high voltage on supported switchers or listing current voltages. Net effect is in best case the kernel and sysfs report lower voltages than are actually set in hardware (1300mV instead of 1800mV for example) and in the worst case setting a voltage (e.g. 1800mV) will cause an undervoltage condition (e.g. 1300mV). Correct the behavior, taking into account SW1 doesn't support the HI bit, and as such we need to ignore it. While we are modifying these functions, fix and optimize the following; * set_voltage_sel callback was using .reg instead of .vsel_reg - since they were set to the same value it actually didn't break anything but it would be semantically incorrect to use .reg in this case. We now use .vsel_reg and be consistent. * vsel_shift is always 0 for every SWx regulator, and constantly shifting and masking off the bottom few bits is time consuming and makes the code very hard to read - optimize this out. * get_voltage_sel uses the variable "val" and set_voltage_sel uses the variable "selector" (and reg_value). Introduce the variable "selector" to get_voltage_sel such that it makes more sense and allow some leaner code in light of the modifications in this patch. Add better exposure to the debug print so the register value AND the selector are printed as this will adequately show the HI bit in the register. * correct a comment in probe which is doing a version check. Magic values are awful but for once instance, a comment does just as good a job as something symbolic.
