regulator: rt5033: Fix n_voltages settings for BUCK and LDO

2021-08-08T06:38:53Z

[ Upstream commit 6549c46af8551b346bcc0b9043f93848319acd5c ] For linear regulators, the n_voltages should be (max - min) / step + 1. Buck voltage from 1v to 3V, per step 100mV, and vout mask is 0x1f. If value is from 20 to 31, the voltage will all be fixed to 3V. And LDO also, just vout range is different from 1.2v to 3v, step is the same. If value is from 18 to 31, the voltage will also be fixed to 3v.

power: supply: ab8500: Fix an old bug

2021-07-20T14:21:09Z

commit f1c74a6c07e76fcb31a4bcc1f437c4361a2674ce upstream. Trying to get the AB8500 charging driver working I ran into a bit of bitrot: we haven't used the driver for a while so errors in refactorings won't be noticed. This one is pretty self evident: use argument to the macro or we end up with a random pointer to something else.

mfd: max8997: Enale irq-wakeup unconditionally

2019-11-28T17:28:38Z

[ Upstream commit efddff27c886e729a7f84a7205bd84d7d4af7336 ] IRQ wake up support for MAX8997 driver was initially configured by respective property in pdata. However, after the driver conversion to device-tree, setting it was left as 'todo'. Nowadays most of other PMIC MFD drivers initialized from device-tree assume that they can be an irq wakeup source, so enable it also for MAX8997. This fixes support for wakeup from MAX8997 RTC alarm.

mfd: mc13xxx-core: Fix PMIC shutdown when reading ADC values

2019-11-28T17:28:37Z

[ Upstream commit 55143439b7b501882bea9d95a54adfe00ffc79a3 ] When trying to read any MC13892 ADC channel on a imx51-babbage board: The MC13892 PMIC shutdowns completely. After debugging this issue and comparing the MC13892 and MC13783 initializations done in the vendor kernel, it was noticed that the CHRGRAWDIV bit of the ADC0 register was not being set. This bit is set by default after power on, but the driver was clearing it. After setting this bit it is possible to read the ADC values correctly.

mfd: da9063: Fix OTP control register names to match datasheets for DA9063/63L

commit 6b4814a9451add06d457e198be418bf6a3e6a990 upstream. Mismatch between what is found in the Datasheets for DA9063 and DA9063L provided by Dialog Semiconductor, and the register names provided in the MFD registers file. The changes are for the OTP (one-time-programming) control registers. The two naming errors are OPT instead of OTP, and COUNT instead of CONT (i.e. control).

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.9 series: Subsystem improvements: - do away with the last users of the obsolete Kconfig options ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter always sounded like an item on a wishlist to Santa Claus to me). We can now select GPIOLIB and be done with it, for all archs. After some struggle it even work on UM. Not that it has GPIO, but if it wants to, it can select the library. - continued efforts to make drivers properly either tristate or bool. - introduce a warning for drivers assigning default triggers to their irqchip lines when probed from device tree, so we find and fix these ambigous drivers. It is agreed that in the OF config path, the device tree defines trigger characteristics. - the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips. - we introduce the ability to mark certain IRQ lines as "unusable" as they can be taken by BIOS/firmware, unrouted in silicon and generally nasty if you use them, and such things. This is put to good use in the STMPE driver and also in the Cherryview pin control driver. - a new "mockup" virtual GPIO device that can be used for testing. The plan is to add unit tests under tools/* for exercising this device and verify that the kernel code paths are working as they should. - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was implicit all the time, but when people started building UM with allyesconfig or allmodconfig it exploded in their face. - move some stray bits of device tree and ACPI HW description callbacks down into their respective implementation silo. These were causing issues when compiling on !HAS_IOMEM as well, so now eventually UM compiles the GPIOLIB library if it wants to. New drivers: - new driver for the Aspeed GPIO front-end companion to the pin controller merged through the pin control tree. - new driver for the LP873x PMIC GPIO portions. - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900, TS-7970, TS-7990 and TS-4100. - new driver for the Broadcom BCM63xx series including BCM6338 and BCM6345. - new driver for the Intel WhiskeyCove PMIC GPIO. - new driver for the Allwinner AXP209 PMIC GPIO portions. - new driver for Diamond Systems 48 line GPIO-MM, another of these port-mapped I/O expansion cards. - support the STMicroelectronics STMPE1600 variant in the STMPE driver. Driver improvements: - the STMPE driver now supports rising/falling edge detection properly for IRQs. - the PCA954x will now fetch and enable its VCC regulator properly. - major rework of the PCA953x driver with the goal of eventually switching it over to use regmap and thus modernize it even more. - switch the IOP driver to use the generic MMIO GPIO library. - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver over to this subsystem from MFD, achieveing some separation of concerns" * tag 'gpio-v4.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (81 commits) gpio: add missing static inline gpio: OF: localize some gpiochip init functions gpio: acpi: separation of concerns gpio: OF: separation of concerns gpio: make memory-mapped drivers depend on HAS_IOMEM gpio: stmpe: use BIT() macro gpio: stmpe: forbid unused lines to be mapped as IRQs mfd/gpio: Move HTC GPIO driver to GPIO subsystem gpio: MAINTAINERS: Add an entry for GPIO mockup driver gpio/mockup: add virtual gpio device gpio: Added zynq specific check for special pins on bank zero gpio: axp209: Implement get_direction gpio: aspeed: remove redundant return value check gpio: loongson1: remove redundant return value check ARM: omap2: fix missing include gpio: tc3589x: fix up complaints on unsigned gpio: tc3589x: add .get_direction() and small cleanup gpio: f7188x: use gpiochip_get_data instead of container_of gpio: tps65218: use devm_gpiochip_add_data() for gpio registration gpio: aspeed: fix return value check in aspeed_gpio_probe() ...
