ARM: PRIMA2: fix irq domain size and IRQ mask of internal interrupt controller
the old codes will cause 3.4 kernel warning as irq domain size is wrong: ------------[ cut here ]------------ WARNING: at kernel/irq/irqdomain.c:74 irq_domain_legacy_revmap+0x24/0x48() Modules linked in: [<c0013f50>] (unwind_backtrace+0x0/0xf8) from [<c001e7d8>] (warn_slowpath_common+0x54/0x64) [<c001e7d8>] (warn_slowpath_common+0x54/0x64) from [<c001e804>] (warn_slowpath_null+0x1c/0x24) [<c001e804>] (warn_slowpath_null+0x1c/0x24) from [<c005c3c4>] (irq_domain_legacy_revmap+0x24/0x48) [<c005c3c4>] (irq_domain_legacy_revmap+0x24/0x48) from [<c005c704>] (irq_create_mapping+0x20/0x120) [<c005c704>] (irq_create_mapping+0x20/0x120) from [<c005c880>] (irq_create_of_mapping+0x7c/0xf0) [<c005c880>] (irq_create_of_mapping+0x7c/0xf0) from [<c01a6c48>] (irq_of_parse_and_map+0x2c/0x34) [<c01a6c48>] (irq_of_parse_and_map+0x2c/0x34) from [<c01a6c68>] (of_irq_to_resource+0x18/0x74) [<c01a6c68>] (of_irq_to_resource+0x18/0x74) from [<c01a6ce8>] (of_irq_count+0x24/0x34) [<c01a6ce8>] (of_irq_count+0x24/0x34) from [<c01a7220>] (of_device_alloc+0x58/0x158) [<c01a7220>] (of_device_alloc+0x58/0x158) from [<c01a735c>] (of_platform_device_create_pdata+0x3c/0x80) [<c01a735c>] (of_platform_device_create_pdata+0x3c/0x80) from [<c01a7468>] (of_platform_bus_create+0xc8/0x190) [<c01a7468>] (of_platform_bus_create+0xc8/0x190) from [<c01a74cc>] (of_platform_bus_create+0x12c/0x190) ---[ end trace 1b75b31a2719ed32 ]--- Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Olof Johansson <olof@lixom.net>
