Subject: [PATCH 0/4] Samsung: Move Samsung SoCs GPIO drivers to drivers/gpio

The following changes since commit 61c4f2c81c61f73549928dfd9f3e8f26aa36a8cf:

  Linux 2.6.39 (2011-05-18 21:06:34 -0700)

Kyungmin Park (4):
      Move to Samsung common GPIO library to drivers/gpio
      Move the exynos4 GPIO to drivers/gpio
      Move the s5pv210 GPIO to drivers/gpio
      Move the s5pc100 GPIO to drivers/gpio
