Please make orders correctly (0x0, 0x1, 0x2, 0x3)

Nice catch : )

Could please fix s5pc1xx also?
Please make it one patch.

Thanks.

No need to change. As existing gpio configuration is as per s5pc1xx
specification.

According to S5PC110 TRM, DRV levels are as following,

00 = 1x
10 = 2x
01 = 3x
11 = 4x

Please fix it at s5pc1xx also.

Thanks
Minkyu Kang.

 As per the s5pc110 user manual I have existing configuration is right. If
you are sure then I will change it and resubmit the patch.
