Subject[PATCH v2 2/2] ARM: dts: rockchip: Remove specific cts pullup from veyron
Message-ID<q4pDz-2R2-3@gated-at.bofh.it>
With the previous patch ("rk3288: pull up cts lines") this is redundant,
I sent that patch for the same reason this existed here, so the lines don't
wiggle randomly when disconnected.

Changes in v2:
- Restrict changes only to cts pin, leave rts alone
- CC people with the firefly board
- New patch removing redundant pullup code from veyron
- cover letter
