[PATCH 0/3] ARM: S3C24XX: s3c2416 build fixes

[PATCH 0/3] ARM: S3C24XX: s3c2416 build fixes

[Heiko Stübner]

While testing Tomasz' timer series I came accross some small build problems
in the new code for pinctrl and dt support on s3c24xx.

All 3 patches fix problems in the samsung tree, so should also go thru there.

Heiko Stuebner (3):
  gpio: samsung: add PINCTRL_S3C24XX to exclude options
  pinctrl: s3c24xx: use correct header for chained_irq functions
  ARM: S3C24XX: update uart addresses in s3c2416-dt auxdata

[PATCH 1/3] gpio: samsung: add PINCTRL_S3C24XX to exclude options

[Heiko Stübner]

When a pinctrl driver is loaded legacy gpio support has to be disabled.
The code checking for the pinctrl presence is contained in an #ifdef
checking for the presence of a valid samsung pinctrl driver.

There the new PINCTRL_S3C24XX was missing resulting in the check never
being run and the gpio being enabled breaking the pinctrl driver.

Fix this by adding the missing CONFIG_PINCTRL_S3C24XX

[PATCH 2/3] pinctrl: s3c24xx: use correct header for chained_irq functions

[Heiko Stübner]

chained_irq_enter and chained_irq_exit moved to a real header under
linux/pinctrl instead of asm/.

Update the pinctrl driver to use the correct header and fix the build
error.

[PATCH 3/3] ARM: S3C24XX: update uart addresses in s3c2416-dt auxdata

[Heiko Stübner]

Commit 9ee51f01eee8 (tty: serial/samsung: make register definitions global)
removed the S3C2410_PA_UARTX defines that the newly merged s3c2416 dt
support still expected.

So update mach-s3c2416-dt.c to use the S3C24XX_PA_UART constant
until we have support for the common clock framework the the s3c2416-dt.

Yeah, this is needed :-)

Linus, shall I take this into samsung tree? Or since the pinctrl-s3c24xx already merged into arm-soc, this could be picked into your tree...

I wonder if this wouldn't be simply covered by PINCTRL_SAMSUNG (except 
PINCTRL_EXYNOS5440 which doesn't use the common part).

No that should work fine. Nothing is touching pinctrl-s3c in my

Right, but this shouldn't have any effect on this code. PINCTRL_S3C64XX isn't 
selected by anything yet, so PINCTRL_SAMSUNG won't be selected when 
ARCH_S3C64XX is used.

As for s3c64xx DT support, I'm planning to finally post patches this week.

Best regards,
Tomasz

I'm not rebasing pinctrl agains the ARM SoC tree,
I only rebase to Torvalds tree.

So please take it through the Samsung tree...
