[PATCH v3 09/15] ARM: tegra: Add the DFLL to Tegra124 device tree

From: Tuomas Tynkkynen The DFLL clocksource is a separate IP block from the usual clock-and-reset controller, so it gets its own device tree node. Signed-off-by: Tuomas Tynkkynen --- arch/arm/boot/dts/tegra124.dtsi | 22 ++ 1 file changed, 22 insertions(+) diff --git a/arc

[PATCH v3 04/15] clk: tegra: Add functions for parsing CVB tables

From: Tuomas Tynkkynen Tegra CVB tables encode the relationship between operating voltage and optimal frequency as a function of the so-called speedo value. The speedo value is written to the on-chip fuses at the factory, which allows the voltage-frequency operating points to be calculated on an

[PATCH v3 01/15] clk: tegra: Add binding for the Tegra124 DFLL clocksource

From: Tuomas Tynkkynen The DFLL is the main clocksource for the fast CPU cluster on Tegra124 and also provides automatic CPU rail voltage scaling as well. The DFLL is a separate IP block from the usual Tegra124 clock-and-reset controller, so it gets its own node in the device tree. Signed-off-by

[PATCH v3 10/15] ARM: tegra: Enable the DFLL on the Jetson TK1

From: Tuomas Tynkkynen Add the board-specific properties of the DFLL for the Jetson TK1 board. On this board, the DFLL will take control of the sd0 regulator on the on-board AS3722 PMIC. Signed-off-by: Tuomas Tynkkynen --- arch/arm/boot/dts/tegra124-jetson-tk1.dts | 8 +++- 1 file changed,

[PATCH v3 06/15] clk: tegra: Add Tegra124 DFLL clocksource platform driver

From: Tuomas Tynkkynen Add basic platform driver support for the fast CPU cluster DFLL clocksource found on Tegra124 SoCs. This small driver selects the appropriate Tegra124-specific characterization data and integration code. It relies on the DFLL common code to do most of the work. Signed-off-

[PATCH v3 03/15] clk: tegra: Add closed loop support for the DFLL

From: Tuomas Tynkkynen With closed loop support, the clock rate of the DFLL can be adjusted. The oscillator itself in the DFLL is a free-running oscillator whose rate is directly determined the supply voltage. However, the DFLL module contains logic to compare the DFLL output rate to a fixed ref

[PATCH v3 00/15] Tegra124 CL-DVFS / DFLL clocksource, plus cpufreq

From: Tuomas Tynkkynen v3 changes: - Fix incorrect order of arguments to dfll_scale_dvco_rate - Fix accidental commas at end-of-statement to semicolons - Some cpufreq changes: - rename cpufreq-tegra to cpufreq-tegra20 - have separate Kconfig entries for Tegra20/Tegra124 support - use

[PATCH v3 12/15] cpufreq: tegra: Rename tegra-cpufreq to tegra20-cpufreq

From: Tuomas Tynkkynen The Tegra124 will use a different driver for frequency scaling, so rename the old driver (which handles only Tegra20) appropriately. Signed-off-by: Tuomas Tynkkynen --- v3: New patch --- drivers/cpufreq/Kconfig.arm| 6 +++--- drivers/cpufreq/M

[PATCH v3 05/15] clk: tegra: Add DFLL DVCO reset control for Tegra124

From: Paul Walmsley The DVCO present in the DFLL IP block has a separate reset line, exposed via the CAR IP block. This reset line is asserted upon SoC reset. Unless something (such as the DFLL driver) deasserts this line, the DVCO will not oscillate, although reads and writes to the DFLL IP bl

[PATCH v3 02/15] clk: tegra: Add library for the DFLL clock source (open-loop mode)

From: Tuomas Tynkkynen Add shared code to support the Tegra DFLL clocksource in open-loop mode. This root clocksource is present on the Tegra124 SoCs. The DFLL is the intended primary clock source for the fast CPU cluster. This code is very closely based on a patch by Paul Walmsley from December

[PATCH v3 08/15] clk: tegra: Add the DFLL as a possible parent of the cclk_g clock

[PATCH v3 13/15] cpufreq: Add cpufreq driver for Tegra124

From: Tuomas Tynkkynen Add a new cpufreq driver for Tegra124. Instead of using the PLLX as the CPU clocksource, switch immediately to the DFLL. It allows the use of higher clock rates, and will automatically scale the CPU voltage as well. Besides the CPU clocksource switch, we let the cpufreq-cpu

[PATCH v3 11/15] cpufreq: tegra124: Add device tree bindings
