Subject: sunxi: Fix clock_twi_onoff for sun8i-a83
X-Git-Tag: v2016.05-rc1~180^2~28
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=a93b0fe3fdd65bfd79f8b77ff828347c8e382eb2;p=u-boot

sunxi: Fix clock_twi_onoff for sun8i-a83

clock_sun8i_a83.c did not contain a clock_twi_onoff implementation
at all, this is fixed by moving the clock_sun6i.c implementation,
which is correct for the a83 too, to a shared location.
