Javier Martinez Canillas a71eb61c9d ARM: OMAP3: igep0020: set GPIO mode for mux mcspi1_cs2 pin ... According to the IGEPv2 Rev.C data-sheet the LAN9221i pin 14 (IRQ) is connected to the OMAP3730 mcspi1_cs2 pin. Since this omap mux pin acts as an IRQ line, it has to be configured as an input GPIO. IGEPv2 platform code sets the smsc911x_cfg->gpio_irq to GPIO 176 but since the mux pin default mode is MODE7 (safe_mode) the driver fails when trying to register the IRQ with the following error message: [ 1.994598] smsc911x: Driver version 2008-10-21 [ 3.704162] irq 272: nobody cared (try booting with the "irqpoll" option) [ 3.711364] [<c001a114>] (unwind_backtrace+0x0/0xf0) from [<c009a0d4>] (__report_bad_irq+0x20/0xbc) [ 3.720916] [<c009a0d4>] (__report_bad_irq+0x20/0xbc) from [<c009a41c>] (note_interrupt+0x1d8/0x238) [ 3.730560] [<c009a41c>] (note_interrupt+0x1d8/0x238) from [<c0098234>] (handle_irq_event_percpu+0xc0/0x260) [ 3.740936] [<c0098234>] (handle_irq_event_percpu+0xc0/0x260) from [<c0098410>] (handle_irq_event+0x3c/0x5c) [ 3.751312] [<c0098410>] (handle_irq_event+0x3c/0x5c) from [<c009abe0>] (handle_level_irq+0xac/0x10c) [ 3.761047] [<c009abe0>] (handle_level_irq+0xac/0x10c) from [<c0097a34>] (generic_handle_irq+0x30/0x48) [ 3.770935] [<c0097a34>] (generic_handle_irq+0x30/0x48) from [<c02a6b74>] (gpio_irq_handler+0x180/0x1d4) [ 3.780944] [<c02a6b74>] (gpio_irq_handler+0x180/0x1d4) from [<c0097a34>] (generic_handle_irq+0x30/0x48) [ 3.790954] [<c0097a34>] (generic_handle_irq+0x30/0x48) from [<c0013e18>] (handle_IRQ+0x4c/0xac) [ 3.800231] [<c0013e18>] (handle_IRQ+0x4c/0xac) from [<c000858c>] (omap3_intc_handle_irq+0x60/0x74) [ 3.809783] [<c000858c>] (omap3_intc_handle_irq+0x60/0x74) from [<c04979e4>] (__irq_svc+0x44/0x60) [ 3.819213] Exception stack(0xee42fde0 to 0xee42fe28) [ 3.824554] fde0: 00000001 00000001 00000000 00000000 60000013 c06cce14 c06cce14 00000110 [ 3.833190] fe00: 00000000 c06ccdf4 60000013 ee41d000 fb058064 ee42fe28 c0089e08 c04976b4 [ 3.841796] fe20: 20000013 ffffffff [ 3.845489] [<c04979e4>] (__irq_svc+0x44/0x60) from [<c04976b4>] (_raw_spin_unlock_irqrestore+0x34/0x44) [ 3.855499] [<c04976b4>] (_raw_spin_unlock_irqrestore+0x34/0x44) from [<c0099744>] (__setup_irq+0x1b8/0x3f0) [ 3.865875] [<c0099744>] (__setup_irq+0x1b8/0x3f0) from [<c0099a34>] (request_threaded_irq+0xb8/0x140) [ 3.875701] [<c0099a34>] (request_threaded_irq+0xb8/0x140) from [<c0487950>] (smsc911x_drv_probe+0x75c/0x11a4) [ 3.886260] [<c0487950>] (smsc911x_drv_probe+0x75c/0x11a4) from [<c02e9bcc>] (platform_drv_probe+0x18/0x1c) [ 3.906707] [<c02e89b8>] (driver_probe_device+0x90/0x210) from [<c02e8bcc>] (__driver_attach+0x94/0x98) [ 3.916625] [<c02e8bcc>] (__driver_attach+0x94/0x98) from [<c02e7298>] (bus_for_each_dev+0x50/0x7c) [ 3.926177] [<c02e7298>] (bus_for_each_dev+0x50/0x7c) from [<c02e81d4>] (bus_add_driver+0x184/0x248) [ 3.935821] [<c02e81d4>] (bus_add_driver+0x184/0x248) from [<c02e909c>] (driver_register+0x78/0x12c) [ 3.945465] [<c02e909c>] (driver_register+0x78/0x12c) from [<c0008648>] (do_one_initcall+0x34/0x178) [ 3.955108] [<c0008648>] (do_one_initcall+0x34/0x178) from [<c066e8f4>] (kernel_init+0xfc/0x1c0) [ 3.964385] [<c066e8f4>] (kernel_init+0xfc/0x1c0) from [<c00140b0>] (kernel_thread_exit+0x0/0x8) [ 3.973632] handlers: [ 3.976043] [<c034e2cc>] smsc911x_irqhandler [ 3.980560] Disabling IRQ #272 Signed-off-by: Javier Martinez Canillas <javier@dowhile0.org> Acked-by: Enric Balletbo i Serra <eballetbo@gmail.com> Tested-by: Enric Balletbo i Serra <eballetbo@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>		2012-08-07 00:01:42 -07:00
