2019-09-05regulator: tps65132: Stop parsing DT when gpio is not foundGuido Günther1-2/+2
In case of a missing (optional) gpio don't fall through up to "ti,active-discharge-time-us" due to devm_fwnode_get_index_gpiod_from_child() returning NULL (since gpiod_get_from_of_node() returned NULL) but rather indicate success as intended. This makes the driver probe correctly when e.g. only the enable gpio is given.

2019-09-04regulator: Defer init completion for a while after late_initcallMark Brown1-11/+31
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.

2019-09-02regulator: provide regulator_bulk_set_supply_names()Bartosz Golaszewski1-0/+21
There are many regulator consumers who - before using the regulator bulk functions - set the supply names in regulator_bulk_data using a for loop. Let's provide a simple helper in the consumer API that allows users to do the same with a single function call.

2019-08-09regulator: twl6030: workaround the VMMC reset behaviorGregory CLEMENT1-1/+14
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.

In the function alps_is_cs19_trackpoint(), we check if the param[1] is in the 0x20~0x2f range, but the code we wrote for this checking is not correct: (param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f, it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f...

2019-07-19Input: add Apple SPI keyboard and trackpad driverRonald Tschalär5-0/+2117
The keyboard and trackpad on recent MacBook's (since 8,1) and MacBookPro's (13,* and 14,*) are attached to an SPI controller instead of USB, as previously. The higher level protocol is not publicly documented and hence has been reverse engineered. As a consequence there are still a number of unknown fields and commands. However, the known parts have been working well and received extensive testing and use. In order for this driver to work, the proper SPI drivers need to be loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci; for all others they are spi_pxa2xx_platform and intel_lpss_pci.
