2018-04-16mfd: mt6397: Add PMIC keys support to MT6397 driverChen Zhong1-1/+21
This patch adds compatible strings and interrupts for pmic keys which serves as child device of MFD. Signed-off-by: Chen Zhong <chen.zhong@mediatek.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2018-04-16mfd: mt6397: Create irq mappings in mfd core driverChen Zhong1-2/+2
The core driver should create and manage irq mappings instead of leaf drivers. This patch change to pass irq domain to devm_mfd_add_devices() and it will create mapping for irq resources automatically. And remove irq mapping in rtc driver since this has been done in core driver.

2017-02-13mfd: mt6397: Add MT6323 LED support into MT6397 driverSean Wang1-0/+4
Add compatible string as "mt6323-led" that will make the OF core spawn child devices for the LED subnode of that MT6323 MFD device. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-05-09mfd: mt6397: IRQ domain should initialize before mfd_add_devices()Henry Chen1-9/+13
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().

2016-04-19mfd: mt6397: Use devm_mfd_add_devices() for mfd_device registrationLaxman Dewangan1-12/+6
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.

2016-03-16mfd: mt6397: Add platform device ID tableJavier Martinez Canillas1-1/+7
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.

2015-08-11mfd: Use irq_desc_get_xxx() to avoid redundant lookup of irq_descJiang Liu1-4/+4
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)".

2015-08-11mfd: Kill off set_irq_flags usageRob Herring1-4/+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.

This adds support for the MediaTek MT6397 PMIC. This is a multifunction device with the following sub modules: - Regulator - RTC - Audio codec - GPIO - Clock It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap.
