* regulator: mc13xxx: Use lowercase regulator names to match the DTRob Herring2019-01-251-39/+39
| | | | | | | | | | | | | | | | | | | | | | | 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 ...

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* regulator: mc13783: consider Power Gates as digital regulators.Alberto Panizzo2010-03-031-6/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GPO regulators are digital outputs that can be enabled or disabled by a dedicated bit in mc13783 POWERMISC register. In this family can be count in also Power Gates (PWGT1 and 2): enabled by a dedicated pin a Power Gate is an hardware driven supply where the output (PWGTnDRV) follow this law: Bit PWGTxSPIEN | Pin PWGTxEN | PWGTxDRV | Read Back 0 = default | | | PWGTxSPIEN ---------------+-------------+----------+------------ 1 | x | Low | 0 0 | 0 | High | 1 0 | 1 | Low | 0 As read back value of control bit reflects the PWGTxDRV state (not the control value previously written) and mc13783 POWERMISC register contain only regulator related bits, a dedicated function to manage these bits is created here with the aim of tracing the real value of PWGTxSPIEN bits and reproduce it on next writes. All POWERMISC users _must_ use the new function to not accidentally disable Power Gates supplies. v2 changes: -Better utilization of abstraction layers. -Voltage query support. GPO's and PWGTxDRV are fixed voltage regulator with voltage value of 3.1V and 5.5V respectively.

* regulator: mc13783-regulator: correct the probing time.Alberto Panizzo2009-12-171-2/+2
| | | | | | | | | | | | | | | | | | | When the mc13783-regulator driver is built in kernel, probing it during the regulator subsystem initialisation result in a fault. That is because regulator subsystem is planned to be initialised very early in the boot process, before the mfd subsystem initialisation. The mc12783-regulator probing process need to access to the mc13783-core functionality to read/write mc13783 registers and so must be called after the mc13783-core driver initialisation. The way to do this is to let the kernel probe the mc13783-regulator driver when mc13783-core register his regulator subdevice.

| | | | | | | | | | | | | | | | | | | | | | | | | - define needed registers and bits in the driver - properly namespace functions and structs - fix locking as required by patch "mfd/mc13783: near complete rewrite" - use platform_data as provided by "mfd/mc13783: near complete rewrite" instead of accessing struct mc13783 - struct mc13783_regulator_priv.desc is (and was) unused and so can go away - use cpp magic to initialize mc13783_regulators - bring MODULE_LICENSE in sync with actual copyright - minor style fixes This allows not including mc13783-private.h which I intend to remove soon.

* regulator/mc13783: rename source file to match other driversUwe Kleine-König2009-12-171-0/+410
One annoying thing about the old name was that the module was just called mc13783 which caused wrong expectations (at least for me).
