[sp] In my opinion, we need to do minimal and necessary MUX settings
in u-boot and let kernel manage itself.

This also helps ensure that problems noticed in kernel are easy
to replicate on other similar platforms. Last year I spent long
time in convincing that wake-up on keypad was not working in Linux
kernel; but folks using OMAP3430SDP maintained it worked fine.
Root cause - relevant PADCONF was set in u-boot for 3430SDP.
(not quoting mail-chain)

We may not be able to eliminate such instances altogether - but
can have less of such instances.

[sp] Can you list what chanages you are trying to propose? ...without
going as far as RFC.

the mails quoted in previous message are again too long and wide
in discussion. A concise list will help.
