2017-02-13mfd: cpcap: Add minimal supportTony Lindgren
Many Motorola phones like droid 4 are using a custom PMIC called CPCAP or 6556002. We can support it's core features quite easily with regmap_spi and regmap_irq. The children of cpcap, such as regulators, ADC and USB, can be just regular device drivers and defined in the dts file. They get probed as we call of_platform_populate() at the end of our probe, and then the children can just call dev_get_regmap(dev.parent, NULL) to get the regmap.

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed.

Use the generic helper to get the matched of_device_id .data, instead of open coding it. The driver was checking if matching the OF node with the driver's OF table was failing, but this doesn't make too much sense since this can't happen in practice. The fact the probe function was called, means OF registered a device with a valid compatible string so a of_device_get_match_data() call will always succeed. So just remove this unneeded check.

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.

2017-02-13mfd: axp20x: Fix AXP806 access errors on cold bootChen-Yu Tsai
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: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Likewise PEK_DBF should be mapped to the falling edge, aka the _N_egative edge, so it should be mapped to AXP288_IRQ_POKN.

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.

2017-02-13mfd: axp20x: Use IRQF_TRIGGER_LOW on the axp288Hans de Goede
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.

It is expected to take a while but there is ongoing interest in that. - SMBus Host Notify introduced 4.9 got refactored. They are now using interrupts instead of the alert callback which solves multiple issues. - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux - significant refactoring for bcm2835 driver - the usual set of driver updates and improvements * 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (46 commits) i2c: fsl-lpi2c: read lpi2c fifo size in probe() i2c: octeon: thunderx: Remove double-check after interrupt i2c: octeon: thunderx: TWSI software reset in recovery i2c: cadence: Allow Cadence I2C to be selected for Cadence Xtensa CPUs i2c: sh_mobile: Add per-Generation fallback bindings i2c: rcar: Add per-Generation fallback bindings i2c: imx-lpi2c: add low power i2c bus driver dt-bindings: i2c: imx-lpi2c: add devicetree bindings i2c: designware-pcidrv: Add 10bit address feature to medfield/merrifield i2c: pxa: Add support for the I2C units found in Armada 3700 i2c: pxa: Add definition of fast and high speed modes via the regs layout dt-bindings: i2c: pxa: Update the documentation for the Armada 3700 i2c: qup: support SMBus block read i2c: qup: add ACPI support i2c: designware: Consolidate default functionality bits i2c: i2c-mux-gpio: update mux with gpiod_set_array_value_cansleep i2c: mux: pca954x: Add ACPI support for pca954x i2c: use an IRQ to report Host Notify events, not alert i2c: i801: remove SMBNTFDDAT reads as they always seem to return 0 i2c: i801: use the BIT() macro for FEATURES_* also ...

Not as big as 4.9 was, but still just over a thousand changes. We almost broke even of lines added vs. removed, as the slicoss driver was removed (got a "clean" driver for the same hardware through the netdev tree), and some iio drivers were also dropped, but I think we ended up adding a few thousand lines to the source tree in the end. Other than that it's a lot of minor fixes all over the place, nothing major stands out at all. All of these have been in linux-next for a while. There will be a merge conflict with Al's vfs tree in the lustre code, but the resolution for that should be pretty simple, that too has been in linux-next" * tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1002 commits) staging: comedi: comedidev.h: Document usage of 'detach' handler staging: fsl-mc: remove unnecessary info prints from bus driver staging: fsl-mc: add sysfs ABI doc staging/lustre/o2iblnd: Fix misspelled attemps->attempts staging/lustre/o2iblnd: Fix misspelling intialized->intialized staging/lustre: Convert all bare unsigned to unsigned int staging/lustre/socklnd: Fix whitespace problem staging/lustre/o2iblnd: Add missing space staging/lustre/lnetselftest: Fix potential integer overflow staging: greybus: audio_module: remove redundant OOM message staging: dgnc: Fix lines longer than 80 characters staging: dgnc: fix blank line after '{' warnings. staging/android: remove Sync Framework tasks from TODO staging/lustre/osc: Revert erroneous list_for_each_entry_safe use staging: slicoss: remove the staging driver staging: lustre: libcfs: remove lnet upcall code staging: lustre: remove set but unused variables staging: lustre: osc: set lock data for readahead lock staging: lustre: import: don't reconnect during connect interpret staging: lustre: clio: remove mtime check in vvp_io_fault_start() ...

2016-11-29mfd: tps65217: Support an interrupt pin as the system wakeupMilo Kim
TPS65217 INT pin is used for the system wakeup from suspend mode. This patch enables push button or charger input event as a wakeup source. Signed-off-by: Milo Kim <woogyom.kim@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-11-29mfd: tps65217: Make an interrupt handler simplerMilo Kim
Rework the IRQ handler by using HW IRQ number and status bit. Each HW IRQ number is matched with TPS65217 register layout[*]. (USB IRQ number is 0, AC is 1, Push button is 2) When an interrupt is enabled, mask bit should be cleared (unmasked). If an interrupt is disabled, then mask bit should be set (masked). This mask value is updated into the TPS65217 register in irq_sync_unlock(). Mask bit and interrupt status bit can be handled with HW IRQ number. Eventually, additional IRQ data, 'tps65217_irqs[]' and the function, 'irq_to_tps65217_irq()' are not necessary.

2016-11-29mfd: tps65217: Update register interrupt mask bits instead of writing operationMilo Kim
TPS65217 interrupt register includes read/writeable mask bits with read-only status bits. (bit 4, 5, 6 are R/W, bit 0, 1, 2 are RO) And reserved bit is not required. Register update operation is preferred for disabling all interrupts during the device initialisation. Signed-off-by: Milo Kim <woogyom.kim@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-11-29mfd: tps65217: Specify the IRQ nameMilo Kim
TPS65217 MFD is an interrupt controller and MFD slave devices like tps65217-charger and tps65217-pwrbutton request an interrupt to handle each HW event. Currently, TPS65217 IRQ name is not defined, so the result is as below. root@arm:~# cat /proc/interrupts ... 182: 0 INTC 7 Level tps65217-irq 183: 0 - 1 Edge tps65217-charger 185: 0 - 2 Edge tps65217_pwrbutton This patch specifies the name of the interrupt controller. 182: 0 INTC 7 Level tps65217-irq 183: 0 tps65217 1 Edge tps65217-charger 185: 0 tps65217 2 Edge tps65217_pwrbutton Signed-off-by: Milo Kim <woogyom.kim@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
