This series introduces support for the DFLL as a CPU clock source on Tegra210. As Jetson TX2 uses a PWM controlled regulator IC which is driven directly by the DFLLs PWM output, we also introduce support for PWM regulators next to I2C controlled regulators. The DFLL output frequency is directly controlled by the regulator voltage. The registers for controlling the PWM are part of the DFLL IP block, so there's no separate linux regulator object involved because the regulator IC only supplies the rail powering the DFLL and the CPUs. It doesn't have any other controls. Changes since v2: * added DT updates for Tegra210 * updated dfll DT binding documentation * split changes to i2c support into its own patch * retrieve regulator parameters from framework rather than from CVB table * bug fixes Changes since v1: * improved commit messages * some style cleanups Laxman Dewangan (1): regulator: core: add API to get voltage constraints Peter De Schrijver (10): clk: tegra: retrieve regulator info from framework clk: tegra: dfll registration for multiple SoCs clk: tegra: add CVB tables for Tegra210 CPU DFLL clk: tegra: prepare dfll driver for PWM regulator clk: tegra: dfll: support PWM regulator control dt-bindings: tegra: Update DFLL binding for PWM regulator clk: tegra: build clk-dfll.c for Tegra124 and Tegra210 cpufreq: tegra124-cpufreq: extend to support Tegra210 arm64: dts: tegra: Add Tegra210 DFLL definition arm64: dts: nvidia: Tegra210 CPU clock definition .../bindings/clock/nvidia,tegra124-dfll.txt | 76 ++- arch/arm64/boot/dts/nvidia/tegra210-p2180.dtsi | 18 + arch/arm64/boot/dts/nvidia/tegra210-p2597.dtsi | 12 + arch/arm64/boot/dts/nvidia/tegra210.dtsi | 26 + drivers/clk/tegra/Kconfig | 5 + drivers/clk/tegra/Makefile | 2 +- drivers/clk/tegra/clk-dfll.c | 462 +++++++++++++++--- drivers/clk/tegra/clk-dfll.h | 2 + drivers/clk/tegra/clk-tegra124-dfll-fcpu.c | 526 ++++++++++++++++++++- drivers/clk/tegra/cvb.c | 16 +- drivers/clk/tegra/cvb.h | 7 +- drivers/cpufreq/tegra124-cpufreq.c | 15 +- drivers/regulator/core.c | 31 ++ include/linux/regulator/consumer.h | 2 + 14 files changed, 1106 insertions(+), 94 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
