Regulators defined at the top level in device tree are no longer part of a simple bus and therefore don't have a reg property. Nodes without a reg property shouldn't have a unit-address either, so drop the unit address from the node names.

2021-08-13ARM: tegra: acer-a500: Remove bogus USB VBUS regulatorsDmitry Osipenko1-24/+1
The configuration of USB VBUS regulators was borrowed from downstream kernel, which is incorrect because the corresponding GPIOs are connected to PROX_EN (A501 3G model) and LED_EN pins in accordance to the board schematics. USB works fine with both GPIOs being disabled, so remove the bogus USB VBUS regulators.

2021-05-31ARM: tegra: acer-a500: Bump thermal trips by 10CDmitry Osipenko1-4/+4
It's possible to hit the temperature of the thermal zone in a very warm environment under a constant load, like watching a video using software decoding. It's even easier to hit the limit with a slightly overclocked CPU. Bump the temperature limit by 10C in order to improve user experience. Acer A500 has a large board and 10" display panel which are used for the heat dissipation, the SoC is placed far away from battery, hence we can safely bump the temperature limit.

2021-05-31ARM: tegra: acer-a500: Specify proper voltage for WiFi SDIO busDmitry Osipenko1-1/+1
Tegra20 has v2.00 SDMMC controller which doesn't support voltage switching and the WiFi SDIO bus voltage is fixed to 1.8v in accordance to the board's schematics, while MMC core confusingly saying that it's 3.3v because of the v2.00.

Acer A500 uses Atmel Maxtouch 1386 touchscreen controller. This controller has WAKE line which could be connected to I2C clock lane, dedicated GPIO or fixed to HIGH level. Controller wakes up from a deep sleep when WAKE line is asserted low.

If CPU0 is unplugged the cooling device can not rebind to CPU1. And if CPU0 is plugged in again, the cooling device may fail to initialize.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM device tree updates from Arnd Bergmann: "Across all platforms, there is a continued move towards DT schema for validating the dts files. As a result there are bug fixes for mistakes that are found using these schema, in addition to warnings from the dtc compiler. As usual, many changes are for adding support for additional on-chip and on-board components in the machines we already support. The newly supported SoCs for this release are: - MStar Infinity2M, a low-end IP camera chip based on a dual-core Cortex-A7, otherwise similar to the Infinity chip we already support. This is also known as the SigmaStar SSD202D, and we add support for the Honestar ssd201htv2 development kit. - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller (BMC), in the same family as the NPCM750. This gets used in the Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of which are added as well. - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own Brahma-B53 CPU. Support is also added for the Asus ROG Rapture GT-AC5300 high-end WiFi router based on this chip. - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores, meant for faster Chromebooks and tablets. It gets added along with its reference design. - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's generation, also added along with its reference board. This one is still based on Cortex-A75/A55. - Mediatek MT8167 is a version of the already supported MT8516 chip, both based on Cortex-A35. It gets added along with the "Pumpkin" single board computer, but is likely to also make its way into low-end tablets in the future. For the already supported chips, there are a number of new boards. Interestingly there are more 32-bit machines added this time than 64-bit. Here is a brief list of the new boards: - Three new Mikrotik router variants based on Marvell Prestera 98DX3236, a close relative of the more common Armada XP - A reference board for the Marvell Armada 382 - Three new servers using ASpeed baseboard management controllers, the actual machines being from Bytedance, Facebook and IBM, and one machine using the Nuvoton NPCM750 BMC. - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412. - The usual set of 32-bit i.MX industrial/embedded hardware: * Protonic WD3 (tractor e-cockpit) * Kamstrup OMNIA Flex Concentrator (smart grid platform) * Van der Laan LANMCU (food storage) * Altesco I6P (vehicle inspection stations) * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard - DH electronics STM32MP157C DHCOM, a PicoITX carrier board for the aleady supported DHCOM module - Three new Allwinner SoC based single-board computers: * NanoPi R1 (H3 based) * FriendlyArm ZeroPi (H3 based) * Elimo Initium SBC (S3 based) - Ouya Game Console based on Nvidia Tegra 3 - Version 5 of the already supported Zynq Z-Turn MYIR Board - LX2162AQDS, a reference platform for NXP Layerscape LX2162A, which is a repackaged 16-core LX2160A - A series of Kontron i.MX8M Mini baseboard/SoM versions - Espressobin Ultra, a new variant of the popular Armada 3700 based board, - IEI Puzzle-M801, a rackmount network appliance based on Marvell Armada 8040 - Microsoft Lumia 950 XL, a phone - HDK855 and HDK865 Hardware development kits for Qualcomm sm8250 and sm8150, respectively - Three new board variants of the "Trogdor" Chromebook (sc7180) - New board variants of the Renesas based "Kingfisher" and "HiHope" reference boards - Kobol Helios64, an open source NAS appliance based on Rockchips RK3399 - Engicam PX30.Core, a SoM based on Rockchip PX30, along with a few carrier boards" * tag 'arm-soc-dt-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (679 commits) arm64: dts: sparx5: Add SGPIO devices arm64: dts: sparx5: Add reset support dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver ARM: mstar: SMP support ARM: mstar: Wire up smpctrl for SSD201/SSD202D ARM: mstar: Add smp ctrl registers to infinity2m dtsi ARM: mstar: Add dts for Honestar ssd201htv2 ARM: mstar: Add chip level dtsi for SSD202D ARM: mstar: Add common dtsi for SSD201/SSD202D ARM: mstar: Add infinity2m support dt-bindings: mstar: Add Honestar SSD201_HT_V2 to mstar boards dt-bindings: vendor-prefixes: Add honestar vendor prefix dt-bindings: mstar: Add binding details for mstar,smpctrl ARM: mstar: Fill in GPIO controller properties for infinity ARM: mstar: Add gpio controller to MStar base dtsi ARM: zynq: Fix incorrect reference to XM013 instead of XM011 ARM: zynq: Convert at25 binding to new description on zc770-xm013 ARM: zynq: Fix OCM mapping to be aligned with binding on zc702 ARM: zynq: Fix leds subnode name for zc702/zybo-z7 ARM: zynq: Rename bus to be align with simple-bus yaml ...

2020-11-18Input: atmel_mxt_ts - fix up inverted RESET handlerLinus Walleij1-1/+1
This driver uses GPIO descriptors to drive the touchscreen RESET line. In the existing device trees this has in conflict with intution been flagged as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by driving the line low (setting to 0) to enter reset state and driving the line high (setting to 1) to get out of reset state. The correct way to handle active low GPIO lines is to provide the GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware) and letting the GPIO framework invert the assertion (driving high) to a low level and vice versa. This is considered a bug since the device trees are incorrectly mis-specifying the line as active high. Fix the driver and all device trees specifying a reset line.

The default parent for all MMCs is PLLP, which is running at 216 MHz on Tegra20 and 50 MHz clock can't be derived from PLLP. The maximum SDIO clock rate is 50 MHz, but this rate isn't achievable using PLLP. Let's switch the WiFi MMC clock parent to PLLC in order to get true 50 MHz.

This patch fixes the wrong PINCTRL configurations and adds a full drive-setup for the changed configs, just for completeness since the added values match the default configuration.

It also turned out that the firmware loading isn't really necessary because it's stored in a non-volatile memory inside of the touchscreen controller and previously the FW loading was needed in order to get touchscreen working, but it actually was a TS driver problem which is resolved now.
