2012-09-22video: exynos_dp: increase AUX channel voltage levelJingoo Han2-2/+2
The value of AUX channel differential amplitude current is changed from 8 mA to 16 mA, in order to increase AUX channel voltage level. In this case, AUX channel voltage level can be changed from 400 mV to 800 mV, when resistance between AUX TX and RX is 100 ohm. According to DP spec, although the normative voltage level is 390 mV, the informative voltage level is 430 mV. So, 800 mV can be helpful to improve voltage margin of AUX channel.

2012-09-22viafb: don't touch clock state on OLPC XO-1.5Daniel Drake1-0/+19
As detailed in the thread titled "viafb PLL/clock tweaking causes XO-1.5 instability," enabling or disabling the IGA1/IGA2 clocks causes occasional stability problems during suspend/resume cycles on this platform. This is rather odd, as the documentation suggests that clocks have two states (on/off) and the default (stable) configuration is configured to enable the clock only when it is needed. However, explicitly enabling *or* disabling the clock triggers this system instability, suggesting that there is a 3rd state at play here. Leaving the clock enable/disable registers alone solves this problem. This fixes spurious reboots during suspend/resume behaviour introduced by commit b692a63a.

equalization To check channel equalization, the value of LANE_ALIGN_STATUS_UPDATED is necessary in exynos_dp_channel_eq_ok(). Also, link_align includes this value. However, link_status does not include this value, so it makes the problem that channel equalization is failed during link training.
