Looks we do the same for pl310: { .name = "pl310", .irq = 0 + OMAP44XX_IRQ_GIC_START }, so u can ignore my comment .. excuse the noise... > >> + { .irq = -1 } >> +}; >> + >> static struct omap_hwmod omap44xx_debugss_hwmod = { >> .name = "debugss", >> .class = &omap44xx_debugss_hwmod_class, >> .clkdm_name = "emu_sys_clkdm", >> + .mpu_irqs = omap44xx_debugss_irqs, >> .main_clk = "trace_clk_div_ck", >> .prcm = { >> .omap4 = { >> @@ -2447,8 +2454,6 @@ static struct omap_hwmod_class omap44xx_mpu_hwmod_class = { >> /* mpu */ >> static struct omap_hwmod_irq_info omap44xx_mpu_irqs[] = { >> { .name = "pl310", .irq = 0 + OMAP44XX_IRQ_GIC_START }, >> - { .name = "cti0", .irq = 1 + OMAP44XX_IRQ_GIC_START }, >> - { .name = "cti1", .irq = 2 + OMAP44XX_IRQ_GIC_START }, >> { .irq = -1 } >> }; >> >> -- >> 1.7.9.5 >> >> >> _______________________________________________ >> linux-arm-kernel mailing list >> linux-arm-kernel@xxxxxxxxxxxxxxxxxxx >> http://lists.infradead.org/mailman/listinfo/linux-arm-kernel -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
