Hi Grant,
I didn't get any comments on this series, gpio-samsung patches for
consolidation of Samsung gpiolib. Please let me know whether this is ok to
you or not. And I think, if you're ok, this should be sent to upstream via
both gpio tree and arm(samsung) tree to avoid conflicts...
As a note, following is its status...
Kukjin Kim (9):
ARM: SAMSUNG: Move map header file into plat-samsung
gpio/s3c24xx: move gpio driver into drivers/gpio/
gpio/s3c64xx: move gpio driver into drivers/gpio/
gpio/s5p64x0: move gpio driver into drivers/gpio/
gpio/samsung: Remove useless old Samsung related GPIO drivers
gpio/samsung: Added gpio-samsung.c to support Samsung GPIOs
ARM: SAMSUNG: Update the name of regarding Samsung GPIO
ARM: SAMSUNG: Remove useless Samsung GPIO related CONFIGs
Merge branch 'next/topic-plat-samsung-1' into next/topic-gpio-samsung

Actually, even though I said I would pick it up, you've already got it
in a tree, so you can go ahead and merge it with my ack. I don't see
any major risk of conflicts for the next merge window, so there is no
need to merge it in the gpio tree also.

Removing this code before adding the new code means it is not
bisectable. I'll squash the two patches together when I pick them
up..

OK, no problem and would be better to me if you could create some topic
branch for this series. I'd like to merge it to avoid conflicts with Samsung
stuff.
Thanks.

This patch adds support for Samsung GPIOs with one gpio driver.
Actually there are drivers/gpio-s3c24xx.c, gpio-s3c64xx.c,
gpio-s5p64x0.c, gpio-s5pc100.c, gpio-s5pv210.c, gpio-exynos4.c,
gpio-plat-samsung.c, plat-samsung/gpio-config.c and gpio.c to
support each Samsung SoCs before.
Basically, the gpio-samsung.c has been made by their merging
and removing duplicated definitions.
Note: gpio-samsung.c includes some SoC dependent codes and it
will be replaced next time.

It's a big driver file, but I'll go ahead and pick this up without too
much review because at least it is all in the same place now. I'll
expect further cleanup in future patches.

Yes, as you said, I agree this is needed some cleanup. I and my team will do
it next time.
Thanks.

According to gpio-samsung.c, this patch updates the name of
regarding Samsung GPIO. Basically the samsung_xxx prefix is
used in gpio-samsung.c instead of s3c_xxx, because unified
name can reduce its complexity.
Note: some s3c_xxx stil remains because it is used widely.
It will be updated next time.
