Subject: [PATCH 0/1] clk: mmp2: Enable the 3D GPU clock alongside the 2D clock


Please consider applying the sad little patch chained to this message. It
is a workaround that makes the 2D GPU work on MMP3 when the 3D GPU is not

It's been observed that the 2D GPU won't work when what is understood to be
the 3D GPU clock is turned off. The etnaviv developers suggest [1][2] that
perhaps said understanding is wrong and they may be right. Unfortunately no
documentation is available, all we know is the register names.

In any case it seems to make more sense to put the workaround in the MMP
clock driver instead of to the etnaviv driver.
