mfd: mt6397: Do not call irq_domain_remove if PMIC unsupported

2019-02-27T09:06:58Z

[ Upstream commit a177276aa098aa47a100d51a13eaaef029604b6d ] If the PMIC ID is unknown, the current code would call irq_domain_remove and panic, as pmic->irq_domain is only initialized by mt6397_irq_init. Return immediately with an error, if the chip ID is unsupported. Signed-off-by: Nicolas Boichat Signed-off-by: Lee Jones Signed-off-by: Sasha Levin

mfd: mt6397: IRQ domain should initialize before mfd_add_devices()

2016-05-09T07:20:22Z

Some sub driver like RTC module need irq domain from parent to create irq mapping when driver initialize. so move mt6397_irq_init() before mfd_add_devices(). Acked-by: John Crispin Signed-off-by: Henry Chen Signed-off-by: Lee Jones

mfd: mt6397: Use devm_mfd_add_devices() for mfd_device registration

2016-04-19T06:55:40Z

Use devm_mfd_add_devices() for MFD devices registration and get rid of .remove callback to remove MFD child-devices. This is done by managed device framework. CC: John Crispin Signed-off-by: Laxman Dewangan Reviewed-by: Javier Martinez Canillas Signed-off-by: Lee Jones

mfd: mt6397: Add platform device ID table

2016-03-16T08:50:32Z

The platform bus_type .match callback attempts to match the platform device name with an entry on the .id_table if provided and fallbacks to match with the driver's name if a table is not provided. Using a platform device ID to match is more explicit, allows the driver to support more than one device and also the MODULE_DEVICE_TABLE macro can be used to export the module aliases information instead of the MODULE_ALIAS.

mfd: mt6397: int_con and int_status may vary in location

2016-03-16T08:50:28Z

MT6323 has the INT_CON and INT_STATUS located at a different position. Make the registers locations configurable. Signed-off-by: John Crispin Signed-off-by: Lee Jones

mfd: mt6397: Implement wake handler and suspend/resume to handle wake up event

2015-08-11T14:09:11Z

Implement .irq_set_wake() to get who is wakeup source and setup on suspend/reumse. Enable mt6393_irq as wake up source properly to pinctrl by enable_irq_wake()/enable_irq_wake(). Signed-off-by: Henry Chen Signed-off-by: Lee Jones

mfd: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-08-11T14:09:06Z

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. Do the same change to avoid the pattern "irq_get_chip_data(data->irq)". Signed-off-by: Jiang Liu 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.
