[PATCH] pinctrl: spacemit: enable config option
Posted by Yixun Lan 1 year ago 
Pinctrl is an essential driver for SpacemiT's SoC,
so let's enable it by default for this SoC.

The CONFIG_PINCTRL_SPACEMIT_K1 isn't enabled when using
'make defconfig' to select kernel configuration options.
This result in a broken uart driver where fail at probe()
stage due to no pins found.

Fixes: a83c29e1d145 ("pinctrl: spacemit: add support for SpacemiT K1 SoC")
Reported-by: Alex Elder <elder@kernel.org>
Signed-off-by: Yixun Lan <dlan@gentoo.org>
---
This should fix problem that CONFIG_PINCTRL_SPACEMIT_K1 is not enabled
when using make defconfig, thus fail to initilize uart driver which requst
pins during probe stage.

This is effectively just "default y", since ARCH_SPACEMIT is a
dependency.

Hi Linus Walleij:
 I think you won't mind if I take this patch through SpacemiT's SoC tree,
as it's fairly SpacemiT specific, right? anyway I'd appreciate if you
could give an ACK for this, thanks

Hi Conor:

right, this is the plan, it make sense to bundle this config to ARCH_SPACEMIT

I don't think I was clear, I was trying to say that you should do
s/ARCH_SPACEMIT/y/ on this line.

make sense, since we already have "depends on ARCH_SPACEMIT" here,
it's kind of redundant to say ARCH_SPACEMIT again, will fix in v2
