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. But in order to change how the core reports modaliases to user-space, it's better to export it. Before this patch: $ modinfo drivers/mfd/tps65912-i2c.ko | grep alias alias: i2c:tps65912 After this patch: $ modinfo drivers/mfd/tps65912-i2c.ko | grep alias alias: of:N*T*Cti,tps65912C* alias: of:N*T*Cti,tps65912 alias: i2c:tps65912 Signed-off-by: NJavier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: NLee Jones <lee.jones@linaro.org>

We didn't have proper device tree bindings for this clock, I standardized it to use the exact chipname so let's rename it "ab8500-clk" and rectify the device tree compatible string to "stericsson,ab8500-clk".

If a driver is only used in DT platforms, there's no need to get the i2c_device_id as an argument of the probe function. Since this data can be get from the matching of_device_id. There's a temporary .probe_new field in struct i2c_driver that can be used as probe callback for the case when i2c_device_id won't be used.

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. 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.

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: NChen-Yu Tsai <wens@csie.org> Signed-off-by: NLee Jones <lee.jones@linaro.org>

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.

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.

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.

palmas_dev and palmas_power_off are always assigned together. So the check for palmas_dev inside palmas_power_off function is redundant. Removing the same. Signed-off-by: NKeerthy <j-keerthy@ti.com> Signed-off-by: NLee Jones <lee.jones@linaro.org>

As DCVDD will often be supplied by a child node of the MFD, we can't call mfd_remove_devices as the first step in arizona_dev_exit as might be expected (tidy up the children before we tidy up the MFD). We need to disable and put the DCVDD regulator before we call mfd_remove_devices, to prevent PM runtime from turning this back on we also need to disable the PM runtime before we do this. Finally we can not clean up the IRQs until all the MFD children have been removed, as they may have registered IRQs themselves. This creates a window of time where the interrupts are enabled but the PM runtime, on which the IRQ handler depends, is not available, any interrupts in this window will go unhandled and fill the log with failed to resume device messages. To avoid this we simply disable the main IRQ at the start of arizona_dev_exit, we don't need to actually handle any IRQs in this window as we are removing the driver.

Enable MWI mechanism if PCI bus master supports it. It might be potential benefit in some cases. Documentation [1] says that standard Memory Write might supply more current data than in the CPU modified cache line and "trashing a line in the cache may trash some data that is more current that in the memory line". This allows to avoid potential retries and other performance degradation issues on the bus. [1] PCI System Architecture, 4th edition, ISBN: 0-201-30974-2, pp.117-119.

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. Add these 2 registers to the regmap so we can access them. Signed-off-by: NChen-Yu Tsai <wens@csie.org> Signed-off-by: NLee Jones <lee.jones@linaro.org>
