-Refer to the IOMUXC controller chapter in imx6q datasheet,
-0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
-80Ohm driver strength and Fast Slew Rate.
+Referring to "Pin Assignments" Table of "i.MX 6Dual/6Quad Applications Processor
+Reference Manual, Rev. 1, 04/2013",
+0x1b0b0 means enable hysteresis, 100KOhm Pull Up, 100Mhz speed,
+40Ohm driver strength and Slow Slew Rate.
User should refer to each SoC spec to set the correct value.
TODO: when dtc macro support is available, we can change above raw data
