ARM: dts: Switch i2c0 to 400kHz on rk3288-evb-rk808
We should be able to talk to the PMIC at 400kHz. No need to talk at the slow 100kHz. As measured by ftrace (with a bunch of extra patches, since cpufreq for rk808 hasn't landed yet): before this change: cpu0_set_target() => ~500us after this change: cpu0_set_target() => ~300us Signed-off-by: Doug Anderson <dianders@chromium.org> Reviewed-by Addy Ke <addy.ke@rock-chips.com> Tested-by Addy Ke <addy.ke@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
