[PATCH 1/5] ARM: Keystone: Enable PINCTRL for Keystone ARCH

[Franklin S Cooper Jr]

From: Franklin Cooper <fcooper@ti.com>

Unlike other Keystone 2 devices, newer Keystone 2 SOCs may utilize
pinmuxing which requires PINCTRL to be enabled. Therefore, enable
PINCTRL for all Keystone 2 devices.

How about:
"depends on ARM || COMPILE_TEST"

I'd much prefer the former actually - it's already hard enough to use
the config tools with the kernel due to the number of silly options
being presented, there's no need to make it worse.

In fact, I'd like to see more of the former (provided done sensibly)
to reduce the number of config options seen for configurations to cut
down on the shere noise of useless options.  For example, if I've
decided I don't want to support TI OMAP platforms, then I shouldn't
be offered the TI OMAP MMC driver.

Okay, fair enough and I don't have any strong opinions around this.

I queued up the patch for next, thanks!

Please notify once MMC patch is accepted and I will

Again. Please shown me the usecases before adding config
option. DTS nodes have to be there.

I would be happy to add this one when I see pin
control data in DTS and its actually going to be
used in upstream kernel. Till then I don't want
to add this one.

Agree. It is too early to add the defconfig update and should be 
deferred to when the DTS update is made. What if the newer keystone 2 
SoC never end up in the tree?
