* mfd: arizona: Correctly clean up after IRQsCharles Keepax2017-02-131-18/+41
| | | | | | | | Currently we leak a lot of things when tearing down the IRQs this patch fixes this cleaning up both the IRQ mappings and the IRQ domain itself. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* mfd: arizona: Use arizona_map_irq instead of hard coding itCharles Keepax2017-02-131-12/+10

* mfd: arizona: Use irq_find_mapping when appropriateCharles Keepax2016-11-291-4/+4
| | | | | | | | | | No need to use irq_create_mapping (although there is no issue with doing so) when we are only looking up an existing mapping. Just to streamline things a little and make the code a little more clear change some calls from irq_create_mapping to irq_find_mapping.

* mfd: arizona: Check if AOD interrupts are pending before dispatchingRichard Fitzgerald2016-06-291-2/+14
| | | | | | | | | | | | | | Previously the arizona_irq_thread implementation would call handle_nested_irqs() to handle AOD interrupts without checking if any were actually pending. The kernel will see these as spurious IRQs and will eventually disable the IRQ. This patch ensures we only launch the nested handler if there are AOD interrupts pending in the codec.

* mfd: arizona: Request parent IRQ before we request child IRQsCharles Keepax2016-01-111-30/+27
| | | | | | | | | | | Currently the driver requests the boot done and control interface IRQs before it has requested its own IRQ line. This can cause problems on edge triggered IRQ systems as if an edge occurs before the parent IRQ is enabled it will be missed. Whilst we are changing the error handling remove an unused label as well. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: arizona: Support Cirrus Logic CS47L24 and WM1831Richard Fitzgerald2015-12-041-13/+27
| | | | | | | | | | | | This patch adds the regmap configuration tables and core MFD handling for the CS47L24 and WM1831 codecs. Note that compared to the other Arizona codecs, these devices do not have an LDO1 or micsupp regulators, extcon driver, or the DCVDD isolation control.

* mfd: arizona: Fix typo in arizona_irq_mapCharles Keepax2015-10-261-1/+1
| | | | | | | | | The type of the data for the main Arizona IRQ chip should be struct arizona not struct regmap_irq_chip_data. The bug is harmless but should probably be corrected anyway.

* mfd: Kill off set_irq_flags usageRob Herring2015-08-111-7/+0
| | | | | | | | | | | | | | | | | | | | | 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: arizona: Use handle_simple_irq for IRQ dispatch chipCharles Keepax2014-09-261-1/+1
| | | | | | | | | We use a dummy IRQ chip to dispatch interrupts to the two seperate IRQ domains on the Arizona devices. This is just a simple software IRQ chip and thus the current handle_edge_irq is unnecessary for its needs.

* mfd: arizona: Propagate irq_wake through to parent IRQCharles Keepax2014-09-261-0/+8

* mfd: arizona: Avoid use of legacy IRQ mappingCharles Keepax2014-09-261-2/+2
| | | | | | | | | | | | | | | regmap_add_irq_chip is called from arizona_irq_init with the irq_base specified as -1 and regmap_add_irq_chip uses if (irq_base) to check if it should use legacy IRQ mapping. As such the irq mappings are currently added with irq_domain_add_legacy, rather than irq_domain_add_linear. This is clearly a typo as there is no reason why this driver can't use irq_domain_add_linear. This patch corrects this by passing the irq_base as zero to regmap_add_irq_chip.

* mfd: arizona: Only free the CTRLIF_ERR IRQ if we requested itCharles Keepax2014-07-281-7/+12
| | | | | | | | | | | | | We only request the control interface error IRQ if we set ctrlif_error, as such we should only free it in that situation. Otherwise we will attempt to free an IRQ we never requested and get a warning from the IRQ core. This patch moves the ctrlif_error variable into the arizona structure and checks it in all cases we free the control interface error IRQ.

* mfd: arizona: Try to use interrupt flags from interrupt controllerMark Brown2013-04-081-2/+25
| | | | | | | | | | | If no irq_flags are passed in platform data then query the interrupt controller for the trigger type and try to use that.

We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...

* mfd: arizona: Interrupt supportMark Brown2012-06-231-0/+267
Several forthcoming Wolfson devices are based on a common platform known as Arizona allowing a great deal of reuse of driver code. This patch adds support for the interrupt controller on Arizona class devices. Since there are two interrupt domains in the device which share a single /IRQ pin by default we use two regmap IRQ domains with a trivial demux interrupt domain used to distribute the interrupts to the two devices. The devices do support multiple interrupt signals, future work will enable support for using this feature to avoid the demux. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
