[PATCH v3 00/19] Add perf support to the rockchip-dfi driver

[Sascha Hauer]

+Cc Lin Huang <hl at rock-chips.com> (original author of the rk3399_dmc driver)

Hi,

I'd like to know how we can proceed with these patches. It would be
great if someone could have a look at them. If this a bandwidth
problem please say so and I'll stay calm for another round ;)
