Clock support for rk3066,rk3188 and rk3288

A patchset in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Wed, 2 Jul 2014 23:48:15 +0200

This series adds a clock driver infrastructure for Rockchip SoCs in general and clock-definitions for the RK3188 and RK3288 in particular. Apart from the arch/arm patches included here, there are some more in the waiting line, like adding the i2c nodes and possibly the pwm, i2s and spi nodes if the relevant drivers get accepted, where the ids defined in the dt-binding headers are needed. So if the whole thing is acceptable could we either offer a branch from the clk-tree that can get merged or take the whole series through the arm tree? changes since v4.2: - fix uninitialized compiler warning in patch4 - add cleanup patch for clk-composite from Mike Turquette - fix some softrst-issues in patch6 changes since v4.1: - forgot the From override, Boris is the original author changes since v4: - address comments from Gabriel Fernandez - use abs() - init best_rate changes since v3: - add rk3288 clock controller - add reset controller ids - fix some incorrect values in rk3188-cru and export some more clocks - fold new rk3066 clock tree into the rk3188 one, as can be easily seen the differences are not really big between them - expand the composite fix description to highlight the underlying issue changes since v2: - drop the special cpuclk type until coordinated range changes matured, as mentioned in the Samsung cpufreq thread. - add the patch from Boris BREZILLON that reenables correct rate calculations in composite clocks - change pll handling to better handle the pll output mux and also the enabling/disabling of the pll clock - change core code to handle composite clock branches instead of individual basic clock definitions - use the newly defined GRF syscon instead of mapping a grf register individually changes since v1: - adapt to apply on current clk-next branch - add saradc clock - add rk3188a cru, which has a slightly different handling of one pll value (bwadj) Boris BREZILLON (1): clk: composite: support determine_rate using rate_ops->round_rate + mux_ops->set_parent Heiko Stuebner (12): clk: composite: allow read-only clocks clk: rockchip: add basic infrastructure for clock branches clk: rockchip: add clock type for pll clocks and pll used on rk3066 clk: rockchip: add reset controller dt-bindings: add documentation for rk3188 clock and reset unit clk: rockchip: add clock driver for rk3188 and rk3066 clocks dt-bindings: add documentation for rk3288 cru clk: rockchip: add clock controller for rk3288 ARM: rockchip: Select ARCH_HAS_RESET_CONTROLLER #### The last 3 patches went through another tree #### #### and the rockchip-3.17-dts series #### ARM: dts: rockchip: add cru nodes and update device clocks to use it ARM: dts: rockchip: move oscillator input clock into main dtsi arm: dts: rockchip: remove obsolete clock gate definitions Mike Turquette (1): clk: composite: improve rate_hw sanity check logic .../bindings/clock/rockchip,rk3188-cru.txt | 61 ++ .../bindings/clock/rockchip,rk3288-cru.txt | 61 ++ .../devicetree/bindings/clock/rockchip.txt | 3 + arch/arm/boot/dts/rk3066a-clocks.dtsi | 299 --------- arch/arm/boot/dts/rk3066a.dtsi | 30 +- arch/arm/boot/dts/rk3188-clocks.dtsi | 289 --------- arch/arm/boot/dts/rk3188.dtsi | 19 +- arch/arm/boot/dts/rk3xxx.dtsi | 22 +- arch/arm/mach-rockchip/Kconfig | 1 + drivers/clk/clk-composite.c | 79 ++- drivers/clk/rockchip/Makefile | 6 + drivers/clk/rockchip/clk-pll.c | 431 +++++++++++++ drivers/clk/rockchip/clk-rk3188.c | 672 +++++++++++++++++++ drivers/clk/rockchip/clk-rk3288.c | 717 +++++++++++++++++++++ drivers/clk/rockchip/clk.c | 244 +++++++ drivers/clk/rockchip/clk.h | 347 ++++++++++ drivers/clk/rockchip/softrst.c | 118 ++++ include/dt-bindings/clock/rk3066a-cru.h | 35 + include/dt-bindings/clock/rk3188-cru-common.h | 249 +++++++ include/dt-bindings/clock/rk3188-cru.h | 51 ++ include/dt-bindings/clock/rk3288-cru.h | 278 ++++++++ 21 files changed, 3386 insertions(+), 626 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/rockchip,rk3188-cru.txt create mode 100644 Documentation/devicetree/bindings/clock/rockchip,rk3288-cru.txt delete mode 100644 arch/arm/boot/dts/rk3066a-clocks.dtsi delete mode 100644 arch/arm/boot/dts/rk3188-clocks.dtsi create mode 100644 drivers/clk/rockchip/clk-pll.c create mode 100644 drivers/clk/rockchip/clk-rk3188.c create mode 100644 drivers/clk/rockchip/clk-rk3288.c create mode 100644 drivers/clk/rockchip/clk.c create mode 100644 drivers/clk/rockchip/clk.h create mode 100644 drivers/clk/rockchip/softrst.c create mode 100644 include/dt-bindings/clock/rk3066a-cru.h create mode 100644 include/dt-bindings/clock/rk3188-cru-common.h create mode 100644 include/dt-bindings/clock/rk3188-cru.h create mode 100644 include/dt-bindings/clock/rk3288-cru.h -- 1.9.0
