Re: [PATCH 1/3] drivers/gpio: Port gpio driver to ls1021a-qds platform

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

Alexander Stein and Uwe Kleine-König are working on this
driver for this kernel cycle so requesting their help in
reviewing these three patches.

Alexander/Uwe: can you see the patches, or will Shaveta
need to resend them?

Do you mean that Freescale has synthesized this GPIO
controller on ARM LE too? In that case that is very useful
information that should go into the commit message.
