[PATCH 0/8] ARM: S5PV310: Add support for Samsung S5PV310 SoC

[Kukjin Kim]

This patch set adds support for Samsung S5PV310/S5PC210. The S5PV310
integrates a ARM Cortex A9 microprocessor with several other peripherals
to support features such as multimedia, storage, graphics and gaming.
The S5PV310 can be used in products such as Netbooks and Mobile devices.

This patch set consists of the following patches.

[PATCH 1/8] ARM: S5P: Remove fixed uart offset dependent code
[PATCH 2/8] ARM: S5PV310: Add new CPU initialization support
[PATCH 3/8] ARM: S5PV310: Add Clock and PLL support
[PATCH 4/8] ARM: S5PV310: Add IRQ support
[PATCH 5/8] ARM: S5PV310: Add Timer support
[PATCH 6/8] ARM: S5PV310: Add new Kconfig and Makefiles
[PATCH 7/8] ARM: S5PV310: Add Board support file
[PATCH 8/8] ARM: S5PV310: Add serial port support

[PATCH 1/8] ARM: S5P: Remove fixed uart offset dependent code

[Kukjin Kim]

From: Changhwan Youn <chaos.youn@samsung.com>

The uart offset between channels has been 0x400 for all S5P series
and to present virtual and physical offsets, both number 0x400 and
S3C_UART_OFFSET have been used together.
This patch removes the use of the number 0x400 and expands the virtual
mapping size of S3C_VA_UART from 4KB to 512KB to support the CPU with
S3C_UART_OFFSET being 0x10000.

[PATCH 4/8] ARM: S5PV310: Add IRQ support

[Kukjin Kim]

From: Changhwan Youn <chaos.youn@samsung.com>

This patch adds IRQ support for S5PV310.
ARM GIC is installed in S5PV310 instead of VIC which is in every other CPUs
in S5P series. Several irq combiners are used to resolve the lack of irq
lines in current implementation.

[PATCH 5/8] ARM: S5PV310: Add Timer support

[Kukjin Kim]

From: Changhwan Youn <chaos.youn@samsung.com>

This patch adds timer support for S5PV310.
Until now, all S5P SoCs use CONFIG_ARCH_USES_GETTIMEOFFSET macro as a default
configuration. Instead, S5PV310 implements clocksource and clock_event_device
to support the high resolution timer and tickless system.

Hmm, why is this lock needed?  The uses below don't seem like they need
locking:

This function is called from set_event().  Do you really want this
printk every time a tick is programmed?

It would probably be prudent to start the clocksource before registering
it, rather than after.

Yeah, you're right.
Will modify it.

Oh, yes.
Will change it.


Thanks.

[PATCH 0/8] ARM: S5PV310: Add support for Samsung S5PV310 SoC

[Kyungmin Park]

Hi,

How about to start the single kernel preparation from this patch?
Instead of create the new machine directory, we just put the
mach-s5pv210 or create the new one.

and don't you think it's confusing of names.
s5pc110 (same as s5pv210), vs. s5pc210 (same as s5pv310).
maybe someone don't read the chip carefully. it's misleading the chips.

Thank you,
Kyungmin Park

[PATCH 8/8] ARM: S5PV310: Add serial port support

[Kyungmin Park]

Hi,

As previous description. it's also same except the udivslot
calculation and clock selection.
How about to just modify current v210 serial codes by just adding the
V310 or C210 type?

Thank you,
Kyungmin Park
