Introduce new alloc/free/mmap methods that take attributes argument.
alloc/free_coherent can be implemented on top of the new alloc/free
calls with NULL attributes. dma_alloc_non_coherent can be implemented
using DMA_ATTR_NONCOHERENT attribute, dma_alloc_writecombine can also
use separate DMA_ATTR_

This patch converts all dma_sg methods to be generic (independent of the

Hello,
This is another update on my attempt on DMA-mapping framework redesign
for ARM architecture. It includes a few minor changes since last
version. We have focused mainly on IOMMU mapper, keeping the DMA-mapping
redesign patches almost unchanged.
All patches have been now rebased onto v3.2-rc
This patch removes the need for offset parameter in dma bounce
functions. This is required to let dma-mapping framework on ARM
architecture use common, generic dma-mapping helpers.

Hi,
This series of patches contains necessary platform modification required by the
G2D driver. G2D is a 2D-graphics acceleration engine present in the S5PC110 and
Exynos4 Samsung SoCs.
The patches have been rebased to the newest kgene/for-next branch. The driver
is currently staging for 3.3 in M

s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined
in the platform data of the i2c device. When DT is not enabled,
the above function always returns -EINVAL. Since there can be
some i2c devices which don't need to configure any gpio lines,
the probe of such devices would fail here. Ch
As the S3C24xx SoCs use the same rtc device a renaming capability like in
the adc driver is necessary.
This patch adds a s3c_rtc_setname function and names the rtc devices for
S3C2443 and S3C2416 accordingly.
