2024-08-01mfd: adp5585: Add Analog Devices ADP5585 core supportHaibo Chen1-0/+12
The ADP5585 is a 10/11 input/output port expander with a built in keypad matrix decoder, programmable logic, reset generator, and PWM generator. This driver supports the chip by modelling it as an MFD device, with two child devices for the GPIO and PWM functions. The driver is derived from an initial implementation from NXP, available in commit 8059835bee19 ("MLK-25917-1 mfd: adp5585: add ADI adp5585 core support") in their BSP kernel tree. It has been extensively rewritten.

Marvell 88PM886 is a PMIC which provides various functions such as onkey, battery, charger and regulators. It is found for instance in the samsung,coreprimevelte smartphone with which this was tested. Implement basic support to allow for the use of regulators and onkey.

2024-06-13mfd: pm8008: Rework to match new DT bindingJohan Hovold1-0/+1
Rework the pm8008 driver to match the new devicetree binding which no longer describes internal details like interrupts and register offsets (including which of the two consecutive I2C addresses the registers belong to). Instead make the interrupt controller implementation internal and pass interrupts to the subdrivers using MFD cell resources. Note that subdrivers may either get their resources, like register block offsets, from the parent MFD or this can be included in the subdrivers directly. In the current implementation, the temperature alarm driver is generic enough to just get its base address and alarm interrupt from the parent driver, which already uses this information to implement the interrupt controller. The regulator driver, however, needs additional information like parent supplies and regulator characteristics so in that case it is easier to just augment its table with the regulator register base addresses. Similarly, the current GPIO driver already holds the number of pins and that lookup table can therefore also be extended with register offsets. Note that subdrivers can now access the two regmaps by name, even if the primary regmap is registered last so that it is returned by default when no name is provided in lookups. Finally, note that the temperature alarm and GPIO subdrivers need some minor rework before they can be used with non-SPMI devices like the PM8008. The temperature alarm MFD cell name specifically uses a "qpnp" rather than "spmi" prefix to prevent binding until the driver has been updated.

Every channel has it's own regulator supply nammed 'vss1-supply' and 'vss2-supply'. The regulator supply is used to determine the output voltage, as the smart switch provides no output regulation. The driver requires the 'shunt-resistor-micro-ohms' to be present in the devicetree to properly calculate current related values.

2023-01-12ARM: sa1100: remove unused board filesArnd Bergmann1-1/+1
The Cerf, H3100, Badge4, Hackkit, LART, NanoEngine, PLEB, Shannon and Simpad machines were all marked as unused as there are no known users left. Remove all of these, along with references to them in defconfig files and drivers. Four machines remain now: Assabet, Collie (Zaurus SL5500), iPAQ H3600 and Jornada 720, each of which had one person still using them, with Collie also being supported in Qemu.

2022-12-08mfd: Drop obsolete dependencies on COMPILE_TESTJean Delvare1-8/+8
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. As a minor optimization, this also lets us drop of_match_ptr(), as we now know what it will resolve to, we might as well save cpp some work.

2022-12-07mfd: tps65219: Add driver for TI TPS65219 PMICJerome Neanne1-0/+14
The TPS65219 is a power management IC PMIC designed to supply a wide range of SoCs in both portable and stationary applications. Any SoC can control TPS65219 over a standard I2C interface. It contains the following components: - Regulators. - Over Temperature warning and Shut down. - GPIOs - Multi Function Pins (MFP) - power-button This patch adds support for tps65219 PMIC. At this time only the functionalities listed below are made available: - Regulators probe and functionalities - warm and cold reset support - SW shutdown support - Regulator warnings via IRQs - Power-button via IRQ Signed-off-by: Jerome Neanne <[email protected]> Signed-off-by: Markus Schneider-Pargmann <[email protected]> Signed-off-by: Lee Jones <[email protected]> Link: https://lore.kernel.org/r/[email protected]

2022-12-07mfd: intel_soc_pmic: Allow COMPILE_TEST or I2C_DESIGNWARE_PLATFORMRandy Dunlap1-1/+1
Linus expressed a desire to have intel_soc_pmic_crc.o (INTEL_SOC_PMIC, for Crystal Cove) be built on an "allmodconfig" build, when I2C_DESIGNWARE_PLATFORM=m, to enhance build test coverage. The PMIC driver won't work in this case since it requires I2C_DESIGNWARE_PLATFORM=y to operate properly, but adding "|| COMPILE_TEST" does improve the build test coverage.
