drivers: interrupt_controller: Add XMC4XXX ERU driver In Infineon XMC4XXX SoCs, gpio interrupts are triggered via an Event Request Unit (ERU) module. A subset of the gpios are connected to the ERU. The ERU monitors edge triggers and creates a SR. This driver configures the ERU for a target port/pin combination for rising/falling edge events. Note that the ERU module does not generate SR based on the gpio level. Internally the ERU tracks the status of an event. The status is set on a positive edge and unset on a negative edge (or vice-versa depending on the configuration). The value of the status is used to implement a level triggered interrupt; The ISR checks the status flag and calls the callback function if the status is set. The ERU configurations for supported port/pin combinations are stored in a devicetree file dts/arm/infineon/xmc4xxx_x_x-intc.dtsi. The configurations are stored in the opaque array uint16 port_line_mapping[]. Signed-off-by: Andriy Gelman <andriy.gelman@gmail.com> 2022-07-21 20:33:28 +02:00			`# XMC4XXX INTC configuration`
