This allows the corresponding I/O -regions to be properly requested and visible in /proc/iomem. - -The main motivation for this change is that the introduction of the -MSI support requires us to get the physical address of the main -interrupt controller registers, so we will need the corresponding -'struct resource' anyway. - -We also take this opportunity to change a panic() to BUG_ON(), in -order to be consistent with the rest of the driver. - -Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> -Tested-by: Daniel Price <daniel.price@gmail.com> -Acked-by: Gregory CLEMENT <gregory.clement@free-electrons.com> ---- - drivers/irqchip/irq-armada-370-xp.c | 20 ++++++++++++++++---- - 1 file changed, 16 insertions(+), 4 deletions(-) - ---- a/drivers/irqchip/irq-armada-370-xp.c -+++ b/drivers/irqchip/irq-armada-370-xp.c -@@ -248,12 +248,25 @@ armada_370_xp_handle_irq(struct pt_regs - static int __init armada_370_xp_mpic_of_init(struct device_node *node, - struct device_node *parent) - { -+ struct resource main_int_res, per_cpu_int_res; - u32 control; - -- main_int_base = of_iomap(node, 0); -- per_cpu_int_base = of_iomap(node, 1); -+ BUG_ON(of_address_to_resource(node, 0, &main_int_res)); -+ BUG_ON(of_address_to_resource(node, 1, &per_cpu_int_res)); - -+ BUG_ON(!request_mem_region(main_int_res.start, -+ resource_size(&main_int_res), -+ node->full_name)); -+ BUG_ON(!request_mem_region(per_cpu_int_res.start, -+ resource_size(&per_cpu_int_res), -+ node->full_name)); -+ -+ main_int_base = ioremap(main_int_res.start, -+ resource_size(&main_int_res)); - BUG_ON(!main_int_base); -+ -+ per_cpu_int_base = ioremap(per_cpu_int_res.start, -+ resource_size(&per_cpu_int_res)); - BUG_ON(!per_cpu_int_base); - - control = readl(main_int_base + ARMADA_370_XP_INT_CONTROL); -@@ -262,8 +275,7 @@ static int __init armada_370_xp_mpic_of_ - irq_domain_add_linear(node, (control >> 2) & 0x3ff, - &armada_370_xp_mpic_irq_ops, NULL); - -- if (!armada_370_xp_mpic_domain) -- panic("Unable to add Armada_370_Xp MPIC irq domain (DT)\n"); -+ BUG_ON(!armada_370_xp_mpic_domain); - - irq_set_default_host(armada_370_xp_mpic_domain); - |
