2012-03-21dmaengine: at_hdmac: add slave config operationNicolas Ferre
This patch introduces DMA_SLAVE_CONFIG to at_hdmac Atmel DMA driver. It is needed to fix a regression in the use of atmel-mci.c driver on Atmel AT91 platforms brouth by e2b35f3: "dmaengine/dw_dmac: Fix dw_dmac user drivers to adapt to slave_config changes" We remove some parts of the private structure "at_dma_slave" and use the information provided by "struct dma_slave_config": source/destination peripheral registers and access width. AT_DMA_SLAVE_WIDTH_* values used previously are not needed anymore as we now use the standard ones. Although some conversion functions are needed to match register expected values. Some AT91 sub-architecture specific files are slightly touched by this patch but it cannot be split because it can break compilation.

2012-03-21dmaengine: add context parameter to prep_slave_sg and prep_dma_cyclicAlexandre Bounine

2012-03-21dmaengine/dma_slave: introduce inline wrappersAlexandre Bounine
Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to hide new parameter from current users of affected interfaces. Convert current users to use new wrappers instead of direct calls. Suggested by Russell King [https://lkml.org/lkml/2012/2/3/269].

2012-03-21Revert "video:uvesafb: Fix oops that uvesafb try to execute NX-protected page"Florian Tobias Schandinat
This reverts commit ec0d22e4d563e7cce9f6678e2000900755c2989d. This patch requires exporting 'pcibios_enabled' to avoid breaking modular uvesafb builds. As this gets some opposition by Alan Cox it needs more discussion, revert the patch for now. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2012-03-21OMAPDSS: register dss drivers in module initTomi Valkeinen
We do the dss driver registration in a rather strange way: we have the higher level omapdss driver, and we use that driver's probe function to register the drivers for the rest of the dss devices. There doesn't seem to be any reason for that, and additionally the soon-to-be-merged patch "ARM: OMAP: omap_device: remove omap_device_parent" will break omapdss initialization with the current registration model. This patch changes the registration for all drivers to happen at the same place, in the init of the module.

2012-03-21fbdev: sh_mipi_dsi: add extra phyctrl for sh_mipi_dsi_infoKuninori Morimoto
sh_mipi uses some clocks, but the method of setup depends on CPU. Current SuperH (like sh73a0) can control all of these clocks by CPG (Clock Pulse Generator). It means we can control it by clock framework only. But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS, and only sh7372 has PHYCTRL::PLLDS. But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was overwrote since the callback timing of clock setting was changed by c2658b70f06108361aa5024798f9c1bf47c73374 (fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()). To solve this issue, this patch adds extra .phyctrl. This patch adds detail explanation for unclear mipi settings and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

2012-03-21drm/radeon/kms: add support for the CONST IB to the CS ioctlAlex Deucher
This adds a new chunk id to the CS ioctl to support the INDIRECT_BUFFER_CONST packet. On SI, the CP adds a new engine called the CE (Constant Engine) which runs simulatenously with the DE (Drawing Engine, formerly called the ME). This allows the CP to process two related IBs simultaneously. The CE is tasked with loading the constant data (constant buffers, resource descriptors, samplers, etc.) while the DE loads context register state and issues drawing commands. It's up to the userspace application to sychronize the CE and the DE using special synchronization packets.
