mfd: qcom-pm8xxx: Clean up PM8XXX namespace

2016-11-21T12:54:28Z

The Kconfig and file naming for the PM8xxx driver is totally confusing: - Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel users depending on or selecting either at random. - A driver file named pm8921-core.c even if it is indeed used by the whole PM8xxx family of chips. - An irqchip named pm8xxx since it was (I guess) realized that the driver was generic for all pm8xxx PMICs. As I may want to add support for PM8901 this is starting to get really messy. Fix this situation by: - Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX and convert all users, including LEDs Kconfig and ARM defconfigs for qcom and multi_v7 to use that single symbol. - Renaming the driver to qcom-pm8xxx.c to fit along the two other qcom* prefixed drivers. - Rename functions withing the driver from 8921 to 8xxx to indicate it is generic. - Just drop the =m config from the pxa_defconfig, I have no clue why it is even there, it is not a Qualcomm platform. (Possibly older Kconfig noise from saveconfig.)

mfd: pm8921: Add support for pm8018

In order to support the Qualcomm MDM9615 PMIC, add support for the pm8018 in pm8921 MFD driver. Signed-off-by: Neil Armstrong Reviewed-by: Bjorn Andersson Signed-off-by: Lee Jones

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51Z

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

mfd: pm8921: Consolidate chained IRQ handler install/remove

2015-08-11T14:09:04Z

Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Reported-by: Russell King Signed-off-by: Thomas Gleixner Signed-off-by: Lee Jones

mfd: Kill off set_irq_flags usage

2015-08-11T14:09:01Z

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

mfd: pm8921: Implement irq_get_irqchip_state

2015-08-11T14:08:54Z

Implement irq_chip->irq_get_irqchip_state to make it possible for PMIC block drivers to access the IRQ real time status bits. The status bits are used for various kinds of input signals, e.g. GPIO. Signed-off-by: Bjorn Andersson Acked-by: Linus Walleij Signed-off-by: Lee Jones

mfd: drop owner assignment from platform_drivers

2014-10-20T14:20:53Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

mfd: pm8921: Remove pm8xxx API now that sub-devices use regmap

The pm8xxx read/write wrappers are no longer necessary now that all the sub-device drivers are using the regmap API. Remove it. Signed-off-by: Stephen Boyd Signed-off-by: Lee Jones

mfd: pm8921: Fixup probe() error path when irq invalid

2014-03-19T08:58:39Z

platform_get_irq() returns a negative error code when an IRQ is invalid or unspecified. Make 'irq' signed to properly handle this. Reviewed-by: Stephen Boyd Signed-off-by: Josh Cartwright Signed-off-by: Lee Jones
