2022-04-21ARM: omap1: move mach/usb.h to include/linux/socArnd Bergmann19-38/+52
The register definitions in this header are used in at least four different places, with little hope of completely cleaning that up. Split up the file into a portion that becomes a linux-wide header under include/linux/soc/ti/, and the parts that are actually only needed by board files.

2022-04-21fbdev: omap: pass irqs as resourceArnd Bergmann5-6/+39
To avoid relying on the mach/irqs.h header, stop using OMAP_LCDC_IRQ and INT_1610_SoSSI_MATCH directly in the driver code, but instead pass these as resources.

2022-04-21ARM: omap1: declare a dummy omap_set_dma_priorityArnd Bergmann1-0/+3
omapfb calls directly into the omap_set_dma_priority() function in the DMA driver. This prevents compile-testing omapfb on other architectures. Add an inline function next to the other ones for non-omap configurations.

2022-04-21ARM: omap1: move lcd_dma code into omapfb driverArnd Bergmann10-55/+48
The omapfb driver is split into platform specific code for omap1, and driver code that is also specific to omap1. Moving both parts into the driver directory simplifies the structure and avoids the dependency on certain omap machine header files. As mach/lcd_dma.h can not be included from include/linux/omap-dma.h any more now, move the omap_lcd_dma_running() declaration into the omap-dma header, which matches where it is defined.

2022-04-21vfio/mdev: Use the driver core to create the 'remove' fileJason Gunthorpe3-9/+13
The device creator is supposed to use the dev.groups value to add sysfs files before device_add is called, not call sysfs_create_files() after device_add() returns. This creates a race with uevent delivery where the extra attribute will not be visible. This was being done because the groups had been co-opted by the mdev driver, now that prior patches have moved the driver's groups to the struct device_driver the dev.group is properly free for use here.

2022-04-21drm/i915/gvt: move the gvt code into kvmgt.koChristoph Hellwig12-153/+192
Instead of having an option to build the gvt code into the main i915 module, just move it into the kvmgt.ko module. This only requires a new struct with three entries that the KVMGT modules needs to register with the main i915 module, and a proper list of GVT-enabled devices instead of global device pointer.
