#1333498 — [PATCH] mfd: stmpe: add the proper PWM resources

This adds the PWM resources to the STMPE MFD driver, so that
it can properly grab and use them.

Cc: Thierry Reding <thierry.reding@gmail.com>
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ChangeLog: split this patch off from the PWM driver and sent
separately. This can be merged separately too so we need no
criss-cross between MFD and PWM anymore, Lee: this one is for
you if it looks all right, excess newlines are gone too.

Applied, thanks.
