Thanks for the testing. I'll find more proper way it could be applied
only for exynos5422 boards.

Hi,
I found this patchset was not merget even 3.19 merge window. As you know,
there is no support of legacy early_printk on arm64. I need this patchset to
support exynos arm64 board properly.
Dear Kukjin,
Could you pick up this patchset in your tree?

Chanho Park

Maybe you make this patch on top of the Robert's patch.
As I know, Robert's patch is not yet merged in mainline.
You should specify this dependency in mail thread.

As I know, the exynos3250 has two CPU cores. Why does it have four pmu

IMO it is sufficient it has only two interrupts.

This patch adds __pl330_giveback_descs which give back descriptors when fails
allocating descriptors. It requires to eliminate duplication for
pl330_prep_dma_sg which will be added later.

This patch adds prep_dma_sg function to transfer memory to memory which mapped
in scatter/gather list. The patch move get_burst_len to upwards to call in the
__pl330_prep_dma_mecpy. Some duplicated code was splitted off from
prep_dma_memcpy.

This patchset support device_prep_dma_sg functionality for pl330 dmaengine
driver. The prep_dma_sg function prepares descriptors to transfer between src

The Exynos4412 has 4 cpus and each has a performance counter.
Thus, we should define 4 interrupts which are combined by irq-combiner for arm
pmu.

This patch adds a rotator node for exynos5250. It has different align value of
image size compared with any other chips. So, we should define new compatible

This patch adds a rotator node for exynos4212 and 4412. These have different
limitation of image size compared with the exynos4210. So, we should define
new compatible to distinguish it from the exynos4210.

The exynos4x12 has different address of GATE_IP_IMAGE reg. We should use
EXYNOS4X12_GATE_IP_IMAGE for g2d gating clocks instead of 4210's reg.
In case of mdma node, We don't use it for any exynos4 chipsets. I think we'll
need to change it to 'none' or leave it on.
