Subject: [PATCH v2 1/2] ARM: dts: rockchip: increase vdd_arm voltage for rk3066a based boards
Date: Fri, 15 Jan 2016 21:25:21 +0800	[thread overview]
Message-ID: <1452864321-505-1-git-send-email-andy.yan@rock-chips.com> (raw)
In-Reply-To: <1452864223-423-1-git-send-email-andy.yan@rock-chips.com>

The current vdd_arm voltage is too low, increase it will make
the system more stable.

Signed-off-by: Andy Yan <andy.yan@rock-chips.com>

Changes in v2:
- move the opp table to rk3066a.dtsi, make it as the default opp table
  for rk3066a based board.
