From 9574f36fb801035f6ab0fbb1b53ce2c12c17d100 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 30 Jul 2012 10:30:26 +1000 Subject: OMAP/serial: Add support for driving a GPIO as DTR. OMAP hardware doesn't provide a phyisical DTR line, but some configurations may need a DTR line which tracks whether the device is open or not. So allow a gpio to be configured as the DTR line.

Everything the driver needs can be done through the struct device pointer. In case we need to use the OMAP-specific PM function pointers, those can make sure to find the device's platform_device pointer so they can find the struct omap_device through pdev->archdata field.

Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally.
