| 24 | * e.g. polarity/triggerring for internal interrupt sources. | ||
| 25 | * | ||
| 26 | * Platform port should provide NR_UICS-sized array named ppc4xx_core_uic_cfg | ||
| 27 | * with these "fixed" settings: .polarity contains exact value which will | ||
| 28 | * be written (masked with "ext_irq_mask") into UICx_PR register, | ||
| 29 | * .triggering - to UICx_TR. | ||
| 30 | * | ||
| 31 | * Settings for external IRQs can be specified separately by the | ||
| 32 | * board support code. In this case properly sized array of unsigned | ||
| 33 | * char named ppc4xx_uic_ext_irq_cfg should be filled with correct | ||
| 34 | * values using IRQ_SENSE_XXXXX and IRQ_POLARITY_XXXXXXX defines. | ||
| 35 | * | ||
| 36 | * If these arrays aren't provided, UIC initialization code keeps firmware | ||
| 37 | * configuration. Also, ppc4xx_uic_ext_irq_cfg implies ppc4xx_core_uic_cfg | ||
| 38 | * is defined. | ||
| 39 | * | ||
