[PATCH 0/4] HP iPAQ RX1950 patch series

[Vasily Khoruzhick]

Following patch series add support for iPAQ RX1950 PDA - another s3c2442-based
machine.
Almost all drivers for this machine are included in mainline kernel, and port
only lacks battery, WiFi and sound support, they will be added later.

Port still uses machine-specific GPIO API, as generic GPIO lacks GPJ
support and RX1950 actively uses GPJ port. However I do not see any benifits
in using generic GPIO API in machine support file, as it will not be used
with CPU different from s3c2442.

Denis: I hope you'll add your Signed-off at least under first patch.

I doubt that I can get Signed-off from Victor Chukhantsev, as he doesn't
work on port for a long time. 

Regards,
Vasily

[PATCH 2/4] Locate kernel at 0x30108000 if PM_H1940 is enabled

[Vasily Khoruzhick]

If PM_H1940 is enabled, kernel _must_ be located upper then 0x30008000,
because this area (0x30000000-0x30100000) can be used by bootloader. If kernel
is located at 0x30008000, bootloader will corrupt kernel's code during
resume.

Please don't do this conditionally, we can compile kernels supporting
many machines, some of the machines might not be using this boot method.

I'll think over the solution.

1) Make each machine add a relevant sysdev to hook suspend/resume.

2) Update the nand driver to do this, but would (a) need to check what
   else is s3c2440 compatible, and (b) it doesn't know if the system
   has booted from NAND or not.

The samsung specific bits mirroring the gpio API will be removed, I will
add post a schedule for removal notice post the next kernel merge.

The patches look ok. I'm not sure if someone else can vouch for Victor's
approval, or authenticty of patches. However if the main authours are
willing to authenticate the code, then I'll accept this unless someone
else objects.

Maybe it's better to do this in s3c2410_pm_prepare()? I see some machine-
specific gpio configuration there.

Uh, but how to switch pin into function mode via gpiolib API?

Btw, do you plan to merge Christians's patches to add GPJ bank support to 
gpiolib anytime soon? I'd like to modify mach-rx1950.c to use gpiolib instead 
of samsung-specific API, but can't do this without GPJ bank support.

Hi, Ben

What modifications are neccessary for these patches to get them into your 
tree?
I can resend patch series if you want.
