The UniPhier reset driver (drivers/reset/reset-uniphier.c) has been
merged.  Select ARCH_HAS_RESET_CONTROLLER from the SoC Kconfig.

Philipp,

IIRC, you mentioned that you were planning to consolidate the double
gurad by CONFIG_RESET_CONTROLLER and CONFIG_ARCH_HAS_RESET_CONTROLLER.

I have not seen it in the ML, so I am sending this.

Please let me know if you have some updates.

OK, I will merge this patch for now.



BTW, I did not understand some of your commits under way.

    dmaengine: sunx6i: do not depend on reset controller framework

    The reset controller framework provides inline function stubs if
    disabled.

    Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>






As far as I see from drivers/dma/sun6i-dma.c,
the reset control is mandatory for this driver.

Why are you removing the dependency?


Don't you care if it works on run-time
as long as it can build?

I have not taken a close look at it, but
if "dependency loops" is the reason for the change,
please mention it in the git-log.

I do not think we should remove the "depends on"
only for the reason "inline function stubs are already provided".
