Thanks for reposting the patchset Grygorii. I will
take them for the 3.15.

Would be good to get the blessing from DT folks
on first two patches.

[PATCH v3 1/4] ARM: dts: keystone: add gpio device entry

[Grygorii Strashko]

This patch adds Keystone GPIO IP device definitions in DT which supports
up to 32 GPIO lines and each GPIO line can be configured as separate
interrupt source (so called "unbanked" IRQ).
