Subject: ARM: dts: aspeed: system1: Mark GPIO line high/low
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c8c33f37a6a685ab81436644bce9567e483f8d71;p=users%2Fwilly%2Flinux.git

ARM: dts: aspeed: system1: Mark GPIO line high/low

- Mark following GPIO lines as input high:
  - GPIOL4 (reset PCH registers)
  - GPIOL5 (reset portition of intel ME)
- Mark isolate errors from cpu1 gpio (GPIOO6) as active low output.
- The fan controller reset line should be active high.
