From a3e633d661fd734956e26bf36800a6dd0dc00710 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 12 Nov 2019 11:11:56 -0600 Subject: ARM: dts: logicpd-torpedo-baseboard: Enable HDQ The baseboard of the Logic PD Torpedo development kit has a socket for a rechargable battery. The battery is monitored by a charger which can communicate of the the 1-wire HDQ pin. This patch enables the pinmux for the HDQ pin.

The work around for this bug was to set CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK=4 in the kernel. This work around is no longer needed as the video drivers have been corrected. This patch removes the legacy note.

This incorrect polarity was defined already in the commit 30d95c6d7092 ("ARM: dts: omap3: Add Technexion TAO3530 SOM omap3-tao3530.dtsi") in v3.18 kernel and later changed to use defined GPIO constants in v4.4 kernel by the commit 3a637e008e54 ("ARM: dts: Use defined GPIO constants in flags cell for OMAP2+ boards"). While the latter commit did not introduce the issue I'm marking it with Fixes tag due the v4.4 kernels still being maintained.

This is configured in the Motorola Mapphone Linux kernel sources as "zerov_regulator". As we currently don't support off mode during idle for omap4, we must prevent vcsi from being disabled when the display is blanked to prevent the PMIC change to off mode. Otherwise the device will hang on entering idle when the display is blanked. Before commit 089b3f61ecfc ("regulator: core: Let boot-on regulators be powered off"), the boot-on regulators never got disabled like they should and vcsi did not get turned off on idle. Let's fix the issue by setting vcsi to always-on for now. Later on we may want to claim the vcsi regulator also in the PM code if needed.
