* ARM: OMAP1: DMA: fix error handling in omap1_system_dma_init()Wei Yongjun2013-05-081-4/+4
| | | | | | | | | | Add the missing iounmap() before return from omap1_system_dma_init() in the error handling case. Also removed platform_device_del() on add resources error case which cause dup device delete.

* ARM: OMAP: Fix dmaengine init for multiplatformTony Lindgren2013-01-111-2/+16
| | | | | | | | | | | | Otherwise omap dmaengine will initialized when booted on other SoCs. Fix this by initializing the platform device in arch/arm/*omap*/dma.c instead.

* ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.hTony Lindgren2012-11-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

* ARM: OMAP: Remove cpu_is_omap usage from plat-omap/dma.cTony Lindgren2012-10-311-0/+3
| | | | | | | | | | | | | | | | | | | | This code will be eventually in drivers, and for the code in the drivers we don't want to have any cpu_is_omap usage. Those macros should be private to arch/arm/mach-omap1 and arch/arm/mach-omap2. To fix this, let's move the define for dma_omap2plus() to dma-omap.h, and use the existing dma_attr passed in the platform_data as the revision registers are what they are. Note that we can now also remove the relative includes introduced by the recent clean-up patches.

| | | | | | | | | | | Some of the omap1 dma channel definitions are used by some drivers. For moving omap1 dma channel definitions to mach-omap1/, the used ones should be defined locally to driver. Driver can eliminate it by using DT, platform data, or IORESOURCE_DMA.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into cleanup-makefile-sparse smatch and string-wrapping cleanups for the OMAP subarch code. These changes fix some of the more meaningful warnings that smatch returns for the OMAP subarch code, and unwraps strings that are wrapped at the 80-column boundary, to conform with the current practice.

The offending lines were found with the following command: pcregrep -rnM '"\s*$\s*"' arch/arm/*omap* While here, some messages have been clarified, some pr_warning( ... calls have been converted to pr_warn( ..., and some printk(KERN_* ... have been converted to pr_*.

| | | | | | | | | | | | | | | | Convert DMA library into DMA platform driver and make use of platform data provided by hwmod data base for OMAP2+ onwards.
