GPIO: gpio-dwapb: Enable platform driver binding to MFD driver The Synopsys DesignWare APB GPIO driver only supports open firmware devices. But, like Intel Quark X1000 SOC, which has a single PCI function exporting a GPIO and an I2C controller, it is a Multifunction device. This patch is to enable the current Synopsys DesignWare APB GPIO driver to support the Multifunction device which exports the designware GPIO controller.

gpio: dwapb: Fix rework support for 1 interrupt per port A GPIO Commit da069d5d2b814d9887989dcdb29fb0202eac8b38 ("gpio: dwapb: Rework support for 1 interrupt per port A GPIO"), was an incremental patch that was supposed to provide the delta between v5 and v6 patch set for adding support for 1 interupt per port A GPIO. v5 was applied, then some other feedback came afterwards. However, in my haste I managed to drop the changes made to dwapb_port_property struct. This patch includes those missing changes.

gpio: dwapb: Add support for 1 interrupt per port A GPIO The DesignWare GPIO IP can be configured for either 1 interrupt or 1 per GPIO in port A, but the driver currently only supports 1 interrupt. See the DesignWare DW_apb_gpio Databook description of the 'GPIO_INTR_IO' parameter. This change allows the driver to work with up to 32 interrupts, it will get as many interrupts as specified in the DT 'interrupts' property. It doesn't do anything clever with the different interrupts, it just calls the same handler used for single interrupt hardware. ACPI companion code provided by Hoan Tran <hotran@apm.com>. This was tested on X-Gene by Hoan.
