| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Gumstix Overo is a computer on module using an OMAP3 processor. This module must be plugged into an expansion board. This patch adds a first device tree support for the Overo, using the Tobi expansion board. The current support is able to boot and mount the rootfs from MMC.

| * ARM: dts: AM33XX: Specify reg and interrupt property for all nodesVaibhav Hiremath2012-09-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The device/node resources (like, IORESOURCE_MEM and IORESOURCE_IRQ) are overwritten by hwmod resources, due to all known reasons but that should not be the reason for not providing all the information in the DTS blob. Ideally we should use DTS resource and use HWMOD framework wherever required and for only specific things. Newer platforms like, OMAP5 and AM33XX, we only support DT boot mode, so this patch is preparation for the future where we supposed to get rid of hwmod dependency anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the new devices (like, AM33XX and OMAP5) we now only support DT boot mode of operation and now it is the time to start killing slowly the dependency on hwmod, so with this patch, we are starting with device resources. The idea here is implemented considering to both boot modes - - DT boot mode OF framework will construct the resource structure (currently does for MEM & IRQ resource) and we should respect/use these resources, killing hwmod dependency. If pdev->num_resources > 0, we assume that MEM & IRQ resources have been allocated by OF layer already (through DTB). Once DMA resource is available from OF layer, we should kill filling any resources from hwmod. - Non-DT boot mode Here, pdev->num_resources = 0, and we should get all the resources from hwmod (following existing steps) Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Cc: Tony Lindgren <tony@atomide.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@ti.com> [b-cousson@ti.com: Fix some checkpatch CHECK issues] Signed-off-by: Benoit Cousson <b-cousson@ti.com>
| * ARM: OMAP: omap_device: Fix up resource names when booted with devicetreePeter Ujfalusi2012-09-06
|/ | | | | | | | | | | | | | | | | | | | | | | | | | When booted with some resource will have their name set to NULL. This can cause later kernel crash since this is not expected by the platform code. When we boot without DT the devices are created with platform_device_add() which itself fixes up the missing resource names: if (r->name == NULL) r->name = dev_name(&pdev->dev); The of core also fixes up the resource names when taking the information from DT data - in __of_address_to_resource(): r->name = name ? name : dev->full_name; When we boot OMAP with devicetree: of will create the devices based on the DT data so the resource names are guarantied to be not NULL. Since we have the 'ti,hwmod' tag, we remove the of created resources from the device and re-create them based on hwmod data. If the hwmod data does not specify a name for a resource it will be NULL. This can cause kernel crash if the driver uses platform_get_resource_byname() to get any resource.

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>

* | arm/dts: AM33XX: Set the default status of module to "disabled" stateVaibhav Hiremath2012-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ideally in common SoC dtsi file should set all modules to "disabled" state and it should get enabled in respective EVM/Board dts file as per usage. This patch sets default status of all modules to "disabled" state in am33xx.dtsi file. Currently there are no modules supported as part of Bone and EVM dts support, so care to add entry "status = "okay"" while adding support for any module.
