[PATCH v4 5/9] gpio: gpio-wcove: use first level PMIC GPIO irq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@xxxxxxxxxxxxxxx>

PMIC mfd driver only exports first level irq for GPIO device.
But currently we are reading the irqs from the second level irq
chip, So this patch fixes this issue by adding support to use
first level PMIC GPIO irq.
