In the current boot, clients making use of the AB8500 sysctrl may be probed before the ab8500-sysctrl driver. This gives them -EINVAL, but should rather give -EPROBE_DEFER. Before this, the abx500 clock driver didn't probe properly, and as a result the codec driver in turn using the clocks did not probe properly. After this patch, everything probes properly. Also add OF compatible-string probing. This driver is all device tree, so let's just make a drive-by-fix of that as well. Signed-off-by:

The AXP806 supports either master/standalone or slave mode. Slave mode allows sharing the serial bus, even with multiple AXP806 which all have the same hardware address. This is done with extra "serial interface address extension", or AXP806_BUS_ADDR_EXT, and "register address extension", or AXP806_REG_ADDR_EXT, registers. The former is read-only, with 1 bit customizable at the factory, and 1 bit depending on the state of an external pin. The latter is writable. Only when the these device addressing bits (in the upper 4 bits of the registers) match, will the device respond to operations on its other registers. The AXP806_REG_ADDR_EXT was previously configured by Allwinner's bootloader. Work on U-boot SPL support now allows us to switch to mainline U-boot, which doesn't do this for us. There might be other bare minimum bootloaders out there which don't to this either. It's best to handle this in the kernel. This patch sets AXP806_REG_ADDR_EXT to 0x10, which is what we know to be the proper value for a standard AXP806 in slave mode. Afterwards it will reinitialize the regmap cache, to purge any invalid stale values. Signed-off-by:

The cros_ec driver is still active while the device is suspended. Besides that, it also tries to transfer data even after the I2C host had been suspended. This patch uses a simple flag to prevent this. Signed-off-by:

The LPC bus pinmux configuration on fifth generation Aspeed SoCs depends on bits in both the System Control Unit and the LPC Host Controller.

Whilst describing a device and not a bus, simple-mfd is modelled on simple-bus where child nodes are iterated and registered as platform devices. Some complex devices, e.g. the Aspeed LPC controller, can benefit from address space mapping such that child nodes can use the regs property to describe their resource offsets within the multi-function device.

The AXP223 shares most of its logic with the AXP221 but has some differences for the VBUS power supply driver. Thus, to probe the driver with the correct compatible, the AXP221 and the AXP223 now have separate MFD cells. AXP221 MFD cells are renamed from axp22x_cells to axp221_cells to avoid confusion.

The adc-enable register for the axp288 is 0x82, not 0x84. 0x82 is already defined as AXP20X_ADC_EN1 and that is what the axp288_adc driver is actually using, so simply drop the wrong AXP288_PMIC_ADC_EN define. Signed-off-by:

The R in PEK_DBR stands for rising, so it should be mapped to AXP288_IRQ_POKP where the last P stands for positive edge. Likewise PEK_DBF should be mapped to the falling edge, aka the _N_egative edge, so it should be mapped to AXP288_IRQ_POKN. This fixes the inverted powerbutton status reporting by the axp20x-pek driver. Signed-off-by:

The axp288 has the following irqs 2 times: VBUS_FALL, VBUS_RISE, VBUS_OV. On boot / reset the enable flags for both the normal and alt version of these irqs is set. Since we were only listing the normal version in the axp288 regmap_irq struct, we were never disabling the alt versions of these irqs. Add the alt versions to the axp288 regmap_irq struct, so that these get properly disabled. Together with the other axp288 fixes in this series, this fixes the axp288 irq contineously triggering.

The interrupt line of the entire family of axp2xx pmics is active-low, for devicetree enumerated irqs, this is dealt with in the devicetree. ACPI irq resources have a flag field for this too, I tried using this on my CUBE iwork8 Air tablet, but it does not contain the right data. The dstd shows the irq listed as either ActiveLow or ActiveHigh, depending on the OSID variable, which seems to be set by the "OS IMAGE ID" in the BIOS/EFI setup screen. Since the acpi-resource info is no good, simply pass in IRQF_TRIGGER_LOW on the axp288. Together with the other axp288 fixes in this series, this fixes the axp288 irq contineously triggering.

On some newer boards using mkbp we're hooking up non-matrix buttons and switches to the EC but NOT to the main application processor. Let's add kernel support to handle this. Rather than creating a whole new input driver, we'll continue to use cros_ec_keyb and just report the new keys. Signed-off-by:

Timers IPs can be used to generate triggers for other IPs like DAC or ADC. Each trigger may result of timer internals signals like counter enable, reset or edge, this configuration could be done through "master_mode" device attribute. Since triggers could be used by DAC or ADC their names are defined in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger function could be used to check if the trigger is valid or not. "trgo" trigger have a "sampling_frequency" attribute which allow to configure timer sampling frequency. version 8: - change kernel version from 4.10 to 4.11 in ABI documentation version 7: - remove all iio_device related code - move driver into trigger directory version 5: - simplify tables of triggers - only create an IIO device when needed version 4: - get triggers configuration from "reg" in DT - add tables of triggers - sampling frequency is enable/disable when writing in trigger sampling_frequency attribute - no more use of interruptions version 3: - change compatible to "st,stm32-timer-trigger" - fix attributes access right - use string instead of int for master_mode and slave_mode - document device attributes in sysfs-bus-iio-timer-stm32 version 2: - keep only one compatible - use st,input-triggers-names and st,output-triggers-names to know which triggers are accepted and/or create by the device Signed-off-by:

When the axp288_faul_gauge driver was originally merged, it was merged with a dependency on some other driver providing platform data for it. However the battery-data-framework which should provide that data never got merged, resulting in x86 tablets / laptops with an axp288 having no working battery monitor, as before this commit the driver would simply return -ENODEV if there is no platform data. This commit removes the dependency on the platform_data instead checking that the firmware has initialized the fuel-gauge and reading the info back from the pmic. What is missing from the read-back info is the table to map raw adc values to temperature, so this commit drops the temperature and temperature limits properties. The min voltage, charge design and model name info is also missing. Note that none of these are really important for userspace to have. All other functionality is preserved and actually made available by this commit. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=88471Signed-off-by:

When the axp288_charger driver was originally merged, it was merged with a dependency on some other driver providing platform data for it. However the battery-data-framework which should provide that data never got merged, so the axp288_charger as merged upstream has never worked, its probe method simply always returns -ENODEV. This commit removes the dependency on the platform_data instead reading back the charging current and charging voltage that the firmware has set and using those values as the maximum values the user may set.

Intel Apollo Lake SoC exposes serial SPI flash through the LPC device. The SPI flash host controller is not discoverable through PCI config cycles because P2SB (function 0 of the device 13) is hidden by the BIOS. We unhide the device briefly in order to read BAR 0 of the SPI host controller. Signed-off-by:
