Detailed Description

Devicetree macros for the Microchip XEC ECIA interrupt aggregator.

Macros for encoding peripheral interrupt information for the microchip,xec-ecia compatible Embedded Controller Interrupt Aggregator (ECIA). MCHP_XEC_ECIA() packs the GIRQ number, the source bit position within that GIRQ and the aggregated/direct NVIC inputs into a single 32-bit value; MCHP_XEC_ECIA_GIRQ_ENC() encodes the GIRQ and bit position only. The matching MCHP_XEC_ECIA_* accessors extract each field.

MCHP_XEC_ECIA

#define MCHP_XEC_ECIA	(		g,
			gb,
			na,
			nd )

#include <zephyr/dt-bindings/interrupt-controller/mchp-xec-ecia.h>

Value:

(((g) & 0x1f) + (((gb) & 0x1f) << 8) + (((na) & 0xff) << 16) +  \
(((nd) & 0xff) << 24))

Encode peripheral interrupt information into a 32-bit value.

Bits [4:0] hold the GIRQ number (in [8, 26]); bits [12:8] hold the peripheral source bit position (in [0, 31]) within the GIRQ; bits [23:16] hold the aggregated GIRQ NVIC number; bits [31:24] hold the direct NVIC number (for sources without a direct connection, set nd equal to na).

Note

GIRQ22 is a peripheral clock wake only. GIRQ22 and its sources are not connected to the NVIC; use 255 for na and nd.

Parameters

g	GIRQ number, in the range [8, 26].
gb	Peripheral source bit position within the GIRQ, in the range [0, 31].
na	Aggregated GIRQ NVIC number.
nd	Direct NVIC number.

MCHP_XEC_ECIA_GIRQ

#define MCHP_XEC_ECIA_GIRQ

(

e

)

#include <zephyr/dt-bindings/interrupt-controller/mchp-xec-ecia.h>

Value:

((e) & 0x1f)

Extract the GIRQ number from an encoded MCHP_XEC_ECIA() value.

MCHP_XEC_ECIA_GIRQ_ENC

#define MCHP_XEC_ECIA_GIRQ_ENC	(		g,
			b )

#include <zephyr/dt-bindings/interrupt-controller/mchp-xec-ecia.h>

Value:

(((g) & 0x1f) + (((b) & 0x1f) << 8))

Encode a peripheral's GIRQ and GIRQ bit position only.

Parameters

g	GIRQ number, in the range [8, 26].
b	Source bit position within the GIRQ, in the range [0, 31].
