[PATCH 0/2] Bring up rk3399 ddr frequency scaling

these patchset bring up rk3399 ddr frequency scaling flow, use devfreq framework and simple_ondemand policy. Ddr set rate function will implement in dcf controller which run in the ATF, and rk3399 ATF not ready now, so we need finish it when rk3399 ATF ready. Lin Huang (2): clk: rockchip: dmc

[PATCH 2/2] devfreq: rockchip: support rk3399 dmc devfreq

rk3399 do ddr frequency scaling use devfreq framework, use simple_ondemand policy, and use rk3399 dfi controller to get ddr busy time. Signed-off-by: Lin Huang <h...@rock-chips.com> --- drivers/devfreq/Kconfig | 1 + drivers/devfreq/Makefile | 1 + drivers/d

[PATCH 1/2] clk: rockchip: dmc: support rk3399 dmc clock driver

support rk3399 dmc clock driver. Note, ddr set rate function will use dcf controller which run in ATF, it need to fishish it when rk3399 arm trust firmware ready. Signed-off-by: Lin Huang <h...@rock-chips.com> --- drivers/clk/rockchip/Makefile | 1 + drivers/clk/rockchip/clk-
