2022-06-24ARM: tegra: Align gpio-keys node names with dtschemaKrzysztof Kozlowski1-4/+4
The node names should be generic and DT schema expects certain pattern (e.g. with key/button/switch). Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Thierry Reding <treding@nvidia.com>
2022-06-08ARM: tegra: Adjust whitespace around '='Krzysztof Kozlowski1-3/+3
Fix whitespace coding style: use single space instead of tabs or multiple spaces around '=' sign in property assignment. No functional changes (same DTB). Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Thierry Reding <treding@nvidia.com>

2021-12-15ARM: tegra: nexus7: Use common LVDS display device-treeMaxim Schwalm1-51/+3
Make Nexus 7 device-tree to use common LVDS bridge description. This makes device-trees more consistent.

2021-12-14ARM: tegra: Drop reg-shift for Tegra HS UARTThierry Reding1-0/+2
When the Tegra High-Speed UART is used instead of the regular UART, the reg-shift property is implied from the compatible string and should not be explicitly listed. Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-12-14ARM: tegra: Rename top-level regulatorsDmitry Osipenko1-4/+4
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. To ensure nodes aren't duplicated (in which case they would end up merged in the final DTB), append the name of the regulator to the node name.

2021-10-05ARM: tegra: nexus7: Enable USB OTG modeDmitry Osipenko1-2/+23
Nexus 7 has OTG-cable microUSB port, enable OTG mode. USB peripheral devices now can be connected to Nexus 7 using OTG adapter, switching USB port into host mode. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-10-04ARM: tegra: Update Broadcom Bluetooth device-tree nodesDmitry Osipenko1-1/+4
The host-wakeup GPIO is now marked as deprecated in the broadcom-bluetooth device-tree binding, it's replaced with the host-wakeup interrupt. Update Tegra device-trees to the recent version of the Bluetooth binding. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-08-13ARM: tegra: nexus7: Improve thermal zonesDmitry Osipenko1-4/+52
Use skin temperature for maintaining temperature that is suitable specifically for Nexus 7. Add CPU thermal zone that protects silicon. All these changes don't make a significant difference, but it is a more correct definition of thermal zones.

2021-08-13ARM: tegra: nexus7: Add interrupt to temperature sensor nodeDmitry Osipenko1-0/+4
The TEMP_ALERT pin of LM90 temperature sensor is connected to Tegra SoC. Add interrupt property to the temperature sensor for completeness. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-05-31ARM: tegra: nexus7: Enable memory frequency thermal throttling using ACTMONDmitry Osipenko1-1/+3
The ACTMON module monitors activity of memory clients and then devfreq driver makes decisions about a required memory frequency based on info from ACTMON. Add ACTMON device to the thermal zone of Nexus 7 in order to use it as a cooling device which throttles memory freq on overheat.

2021-05-31ARM: tegra: nexus7: Remove monitored-battery propertyDmitry Osipenko1-1/+0
The bq27541 Linux kernel driver will try to reprogram controller based on the values from monitored-battery node, but it fails to do so because controller was locked by manufacturer. Still this is a very undesirable behaviour, hence let's remove the optional battery node. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-05-31ARM: tegra: nexus7: Improve thermal zonesDmitry Osipenko1-9/+2
Remove unused thermal zone just to clean up device-tree and set critical temperature further apart from the passive cooling trip point since during or thermal testing of Asus Transformer devices we found that CPU could reach the critical temperature in a certain kernel configurations for a brief moment if critical trip point is set close to the passive trip point and then device will be immediately shut off without getting a chance to cool down using passive cooling.

2021-03-24ARM: tegra: nexus7: Specify all CPU cores as cooling devicesDmitry Osipenko1-4/+10
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. If the CPUs are mapped with the physical CPU0 to Linux numbering CPU1, the cooling device mapping will fail. Hence specify all CPU cores as a cooling devices in the device-tree.

2020-11-26ARM: tegra: nexus7: Use panel-lvds as the only panel compatibleDmitry Osipenko1-2/+10
Depending on a driver probe order, panel-simple driver may probe first, which results in this error: panel-simple display-panel: Reject override mode: panel has a fixed mode We don't want to use panel-simple anyways because customized timings are preferred for Nexus 7, hence remove the panel-simple compatibles from the panel node.

2020-11-26ARM: tegra: nexus7: Rename gpio-hog nodesDmitry Osipenko1-2/+2
Devicetree schema now requires gpio-hog nodes to have a certain naming pattern, like a -hog suffix. This patch fixes dtbs_check warnings about the names. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2020-11-26ARM: tegra: nexus7: Add power-supply to lvds-encoder nodeDmitry Osipenko1-0/+1
The lvds-encoder binding now supports power-supply property, let's specify it in the device-tree for completeness. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2020-11-26ARM: tegra: nexus7: Improve CPU passive-cooling thresholdDmitry Osipenko1-3/+3
The current CPU thermal limit is a bit inappropriate for Nexus 7 once device is getting used on a daily bases. For example, currently it's may be impossible to watch a hardware accelerated 720p video without hitting a severe CPU throttling, which ruins user experience. This patch improves the thermal throttling thresholds. In my experience setting CPU thermal threshold to 57C provides the most reasonable result, where device is a bit warm under constant load and not getting overly hot, in the same time performance is okay. Let's bump the passive-cooling threshold from 50C to 57C and also lower the thermal hysteresis to 0.2C in order to make throttling more reactive.

2020-11-26ARM: tegra: nexus7: Correct thermal zone namesDmitry Osipenko1-2/+2

2020-09-17ARM: tegra: nexus7: Add touchscreenDmitry Osipenko1-0/+18
Nexus 7 2012 has Elantech EKTF3624 touchscreen, this patch adds TS node to the device-tree. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2020-09-17ARM: tegra: nexus7: Use PLLC for WiFi MMC clock parentDmitry Osipenko1-0/+5
The default parent for all MMCs is PLLP, which is running at 408 MHz on Tegra30 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 doesn't fix any problems, it's just a minor improvement. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2020-09-17ARM: tegra: nexus7: Add aliases for MMCDmitry Osipenko1-2/+5
MMC core now supports binding to a specific ID, which is very handy for embedded devices, like Nexus 7, because MMC ID may change depending on kernel version or configuration which affects MMC driver probe order.
