So we do ddr frequency scaling with following flow: kernel bl31 monitor ddr load | | get_target_rate | | pass rate to bl31 clk_set_rate(ddr) --------------------->run dcf flow | | | | wait dcf interrupt<-------------------trigger dcf interrupt | | return Lin Huang (6): clk: rockchip: add new clock-type for the ddrclk clk: rockchip: rk3399: add SCLK_DDRCLK ID for ddrc clk: rockchip: rk3399: add ddrc clock support PM / devfreq: event: support rockchip dfi controller PM / devfreq: rockchip: add devfreq driver for rk3399 dmc drm/rockchip: Add dmc notifier in vop driver Heiko Stübner (1): clk: rockchip: add clock flag parameter when register pll Lin Huang (6): clk: rockchip: add new clock-type for the ddrclk clk: rockchip: rk3399: add SCLK_DDRCLK ID for ddrc clk: rockchip: rk3399: add ddrc clock support PM / devfreq: event: support rockchip dfi controller PM / devfreq: rockchip: add devfreq driver for rk3399 dmc drm/rockchip: Add dmc notifier in vop driver drivers/clk/rockchip/Makefile | 1 + drivers/clk/rockchip/clk-ddr.c | 146 +++++++++ drivers/clk/rockchip/clk-pll.c | 4 +- drivers/clk/rockchip/clk-rk3399.c | 19 ++ drivers/clk/rockchip/clk.c | 11 +- drivers/clk/rockchip/clk.h | 29 +- drivers/devfreq/Kconfig | 1 + drivers/devfreq/Makefile | 1 + drivers/devfreq/event/Kconfig | 7 + drivers/devfreq/event/Makefile | 1 + drivers/devfreq/event/rockchip-dfi.c | 253 +++++++++++++++ drivers/devfreq/rockchip/Kconfig | 8 + drivers/devfreq/rockchip/Makefile | 1 + drivers/devfreq/rockchip/rk3399_dmc.c | 473 ++++++++++++++++++++++++++++ drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 124 +++++++- include/dt-bindings/clock/rk3399-cru.h | 1 + include/soc/rockchip/rockchip_sip.h | 27 ++ 17 files changed, 1098 insertions(+), 9 deletions(-) create mode 100644 drivers/clk/rockchip/clk-ddr.c create mode 100644 drivers/devfreq/event/rockchip-dfi.c create mode 100644 drivers/devfreq/rockchip/Kconfig create mode 100644 drivers/devfreq/rockchip/Makefile create mode 100644 drivers/devfreq/rockchip/rk3399_dmc.c create mode 100644 include/soc/rockchip/rockchip_sip.h -- 1.9.1
