From 167e62798ccd4172d02c8f10ca7010a301498aa3 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Thu, 9 Aug 2012 16:30:37 +0530 Subject: ARM: dt: tegra: cardhu: add entry for PMIC TPS65911. Tegra30 based platform "cardhu" have the power management IC TPS65911 for the regulator. Adding DT entry for this device. Data are chosen from downstream kernel and making the voltage output as require by default for device to operate. The default interrupt line is HIGH from PMIC device and so inverting the interrupt detection line of PMU interrupt through configuring PMC. In this patch, do not registering LDO5 because the input supply for this rail is different for different version of cardhu i..e A02 and A04. The registration will be done once the dts file for cardhu A02 and A04 are added in follow on patches.

Add support of these power rail control through fixed regulators. Add entry for all fixed regulators for cardhu-a02 and a04. The details are taken from downstream kernel. Some points on this change are: * Add the tps65910-LDO5 entry and make it always ON to supply power to SDMMC. Once the sd driver support regulator handling, this flag will be remove. * Dropping registration of rail vdd_sdmmc1 as the gpio is used by sdhci power-gpio. This need to fix in sdhci driver and then need to add the registration mechanism. Just removing power-gpio and adding fixed regulator with this gpio is causing the sd access to fail because first probe call of this regulator fails due to non-available of parent and so it calls gpio_free() which disable the pins in gpio mode make pin output to LOW causes power to OFF. In probe retry, it got success and it powered-on but it again need to do again numeration of card here.

Instantiate this, and hook up a couple of fixed GPIO-controlled regulators too. Two data sources were used for the data encoded here: * The HW defaults, as extracted from real HW. * The schematic, which specifies a voltage for each LDO rail. In most cases these sources matched. The only differences is: ldo6: The HW default on Springbank is 2.85v. The HW default on Seaboard is 1.8v. The schematics for both Springbank and Seaboard match at 2.85v. However, internal research indicates that the schematics are incorrectly labelled, and 1.8v is correct. The ChromeOS kernel also uses 1.8v. Note that these settings don't entirely match those in the ChromeOS kernel found at the URL below. However, the selected values generally cause no behavior change in the kernel, and so were picked to avoid regressions. repo http://git.chromium.org/chromiumos/third_party/kernel.git branch chromeos-3.2 file arch/arm/mach-tegra/board-seaboard-power.c Portions based on work by Laxman Dewangan Signed-off-by: Stephen Warren diff --git a/arch/arm/boot/dts/tegra20-seaboard.dts b/arch/arm/boot/dts/tegra20-seaboard.dts index 85e621a..92deb36 100644 --- a/arch/arm/boot/dts/tegra20-seaboard.dts +++ b/arch/arm/boot/dts/tegra20-seaboard.dts @@ -374,6 +374,152 @@ status = "okay";

Instantiate this. Three data sources were used for the data encoded here: * The HW defaults, as extracted from real HW. * The schematic, which specifies a voltage for each rail in the signal names. * The AC100 kernel used by the Ubuntu port: repo git://gitorious.org/~marvin24/ac100/marvin24s-kernel.git branch chromeos-ac100-3.0 file arch/arm/mach-tegra/board-paz00-power.c For many rails, the constraints in that tree specified differing min and max voltages. In all cases, the min value was ignored, since there's no need currently to vary any of the voltages at run-time. DVFS might change this in the future. In most cases these sources all matched. Differences are: sm0: HW defaults and schematic match at 1.2v. marvin24's kernel had a max of 1.3v, but this higher voltage was only applied to HW by DVFS code, which isn't currently supported in mainline. sm1: HW defaults and schematic match at 1.0v. marvin24's kernel had a max of 1.125v, but this higher voltage was only applied to HW by DVFS code, which isn't currently supported in mainline. ldo3: The HW default is on. marvin24's kernel didn't specify always-on, but since the board wasn't marked as having fully constrained regulators, the rail was not turned off, so the difference had no effect. The rail is needed for USB. ldo6: The HW default is 2.85v. The schematics indicate 2.85v. However, since this regulator is used for the same purpose as on other boards that require 1.8v, this is set to 1.8v. Note that this regulator feeds the CRT VDAC on Tegra, and so in practice is unlikely to be used, even though it is actaully hooked up in HW.

Instantiate this. The voltage settings were derived from the schematic. The only exception is the BBAT voltage; the schematic says 1.2v, but the HW can't go that low, so use the HW default of 2.4v instead. Almost all regulators list all driven supply signal names in their regulator-names property. The exception is nvvdd_sv3, which is in turn named 12 more different names on the schematic, so these were omitted for brevity.
