Rather than #define the options manually in the architecture code, add Kconfig options for them and select them there instead. This also allows us to select the compat IPC version parsing automatically for platforms using the old compat IPC interface.

mach-netx had its own implementation of clk routines like, clk_get{put}, clk_enable{disable}, etc. And with introduction of following patchset: https://lkml.org/lkml/2012/4/24/154 we get compilation error for multiple definition of these routines. Sascha had following suggestion to deal with it: http://www.spinics.net/lists/arm-kernel/msg179369.html So, remove this code completely.

This patch adds support for DMA_ATTR_SKIP_CPU_SYNC attribute for dma_(un)map_(single,page,sg) functions family. It lets dma mapping clients to create a mapping for the buffer for the given device without performing a CPU cache synchronization. CPU cache synchronization can be skipped for the buffers which it is known that they are already in 'device' domain (CPU caches have been already synchronized or there are only coherent mappings for the buffer). For advanced users only, please use it with care. Signed-off-by: NMarek Szyprowski <m.szyprowski@samsung.com> Reviewed-by: NKyungmin Park <kyungmin.park@samsung.com>

Commit 9adc5374 ('common: dma-mapping: introduce mmap method') added a generic method for implementing mmap user call to dma_map_ops structure. This patch converts ARM and PowerPC architectures (the only providers of dma_mmap_coherent/dma_mmap_writecombine calls) to use this generic dma_map_ops based call and adds a generic cross architecture definition for dma_mmap_attrs, dma_mmap_coherent, dma_mmap_writecombine functions. The generic mmap virt_to_page-based fallback implementation is provided for architectures which don't provide their own implementation for mmap method.

This patch changes dma-mapping subsystem to use generic vmalloc areas for all consistent dma allocations. This increases the total size limit of the consistent allocations and removes platform hacks and a lot of duplicated code. Atomic allocations are served from special pool preallocated on boot, because vmalloc areas cannot be reliably created in atomic context.

On TrimSlice, Tegra's USB1 port may be routed to either an external micro USB port, or an internal USB->SATA bridge for SSD or HDD. This muxing is controlled by a GPIO. Whilst not strictly a VBUS GPIO, the TrimSlice board files caused this GPIO to be set appropriately to enable the SATA bridge by passing it as the VBUS GPIO to the USB driver. Echo this same configuration in device tree to enable the SATA bridge. An alternative might be to implement a full USB bus mux driver. However, that seems over-complex right now.

Commit 98d9986c (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce (ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom variant of clock gating which allows to define a function to be called before gating the clock off. This is used to disable the SATA and PCIe PHYs if the respective clocks are unused after initialization. However, of these two drivers, the SATA driver may be compiled as a module. The driver re-enables the clocks at module init but the PHYs stay disabled. Since the custom clock gating disabled the PHYs when gating the clock off, it should also re-enable them when enabling the clock gate. This is done by adding a second function that may be used to enable the PHYs. Signed-off-by: NSimon Baatz <gmbnomis@gmail.com> Signed-off-by: NAndrew Lunn <andrew@lunn.ch>

Marvell engineers tell us: It seems that many units use the RUNIT clock. SPI, UART, NAND, TWSI, ... So it's not possible to clock gate it. Currently the SPI, NAND and TWSI driver will clk_prepaure_enable() this clk, but since we have no idea what ... is, and turning this clk off results in a hard lock, unconditionally enable runit.

This enables the new EXYNOS5 platforms in the defconfig, and enables DT support on EXYNOS4. Other options enabled: USB host, EXT3/4, regulators and tps65090, networking and a few of the common usb ethernet adapters as well as the smsc911x controller used on some boards. I enabled EFI_PARTITION, since it's used on some filesystem images I'm using. I didn't see a need to keep Solaris and BSD partition format still enabled. Finally, framebuffer console, logo and fonts were enabled. Note that enabling some of these options introduces build coverage previously missing, thus introducing a few build errors and warnings for which fixes have been sent out already.
