From 7afe031c1a49c3630e39ec8d964334d0032fe6da Mon Sep 17 00:00:00 2001 From: Bogdan Purcareata Date: Mon, 5 Feb 2018 08:07:43 -0600 Subject: [PATCH] staging: fsl-mc: Move irqchip code out of staging Now that the fsl-mc bus core infrastructure is out of staging, the remaining irqchip glue code used (irq-gic-v3-its-fsl-mc-msi.c) goes to drivers/irqchip. Create new Kconfig option for irqchip code that depends on FSL_MC_BUS and ARM_GIC_V3_ITS. This ensures irqchip code only gets built on ARM64 platforms. We can now remove #ifdef GENERIC_MSI_DOMAIN_OPS as it was only needed for x86.
