| | * arm: dma-mapping: plumb our iommu mapping ops into arch_setup_dma_opsWill Deacon2014-12-012-14/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch plumbs the existing ARM IOMMU DMA infrastructure (which isn't actually called outside of a few drivers) into arch_setup_dma_ops, so that we can use IOMMUs for DMA transfers in a more generic fashion. Since this significantly complicates the arch_setup_dma_ops function, it is moved out of line into dma-mapping.c. If CONFIG_ARM_DMA_USE_IOMMU is not set, the iommu parameter is ignored and the normal ops are used instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new function to the iommu_ops structure to allow an OF device to be added to a specific IOMMU instance using the recently merged generic devicetree binding for IOMMUs. The callback (of_xlate) takes a struct device representing the master and an of_phandle_args representing the IOMMU and the correspondong IDs for the new master.

| | * dma-mapping: replace set_arch_dma_coherent_ops with arch_setup_dma_opsWill Deacon2014-12-013-27/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_arch_dma_coherent_ops is called from of_dma_configure in order to swizzle the architectural dma-mapping functions over to a cache-coherent implementation. This is currently implemented only for ARM. In anticipation of re-using this mechanism for IOMMU-backed dma-mapping ops too, this patch replaces the function with a broader arch_setup_dma_ops callback which will be extended in future.

| | * iommu: provide early initialisation hook for IOMMU driversWill Deacon2014-12-014-0/+46
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IOMMU drivers must be initialised before any of their upstream devices, otherwise the relevant iommu_ops won't be configured for the bus in question. To solve this, a number of IOMMU drivers use initcalls to initialise the driver before anything has a chance to be probed. Whilst this solves the immediate problem, it leaves the job of probing the IOMMU completely separate from the iommu_ops to configure the IOMMU, which are called on a per-bus basis and require the driver to figure out exactly which instance of the IOMMU is being requested. In particular, the add_device callback simply passes a struct device to the driver, which then has to parse firmware tables or probe buses to identify the relevant IOMMU instance. This patch takes the first step in addressing this problem by adding an early initialisation pass for IOMMU drivers, giving them the ability to store some per-instance data in their iommu_ops structure and store that in their of_node. This can later be used when parsing OF masters to identify the IOMMU instance in question.

This patch updates the timings to the 'typical' values from the LCD spec sheet. Also, the compatible string is completely bogus, as "osddisplays,osd057T0559-34ts" is _not_ a 480x272 panel. The panel on the board is a newhaven one. Update the compatible string to reflect this. Note that this hasn't caused any issues, as the "panel-dpi" matches the driver.
