John Stultz Nov. 6, 2020, 4:27 a.m. UTC 
This patch reworks PINCTRL_MSM to be a visible option, and
instead of having the various SoC specific drivers select
PINCTRL_MSM, this switches those configs to depend on
PINCTRL_MSM.

This is useful, as it will be needed in order to cleanly support
having the qcom-scm driver, which pinctrl-msm calls into,
configured as a module. Without this change, we would eventually
have to add dependency lines to every config that selects
PINCTRL_MSM, and that would becomes a maintenance headache.

We also add PINCTRL_MSM to the arm64 defconfig to avoid
surprises as otherwise PINCTRL_MSM/IPQ* options previously
enabled, will be off.

I applied this patch to the pinctrl tree as well, I suppose
that was the intention. If someone gets upset I can always
pull it out.

Thanks for your perseverance in driving this John.

Yours,

Huh, I hadn't heard anything back on that series and was going to
resend it. Do let me know if you have more thoughts on that one.

thanks
