+Subject: [PATCH 68/70] MIPS: lantiq: stp, fix for ase, add get, clock
+ disabled
+
+Lantiq serial-to-parallel hardware gpio module
+Added gpio pins as used for amazon se (ase)
+Added get to enable reporting of gpio status
+Changed to use software update, as hw clock was not running on ase. Clock
+really only needed if hw flashing was implemented.
