From: Jon Hunter Date: Thu, 18 Jun 2020 11:54:39 +0000 (+0100) Subject: ARM: tegra: Enable PSCI support for Tegra210 and Tegra186 X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1ec74533840650b914ccdf9f62a298ecb29994ab;p=u-boot.git ARM: tegra: Enable PSCI support for Tegra210 and Tegra186 The PSCI nodes are currently not populated for the Tegra210 and Tegra186 devices. This prevents the PSCI driver from being able to identify the PSCI method used by these devices and causes the probe of the PSCI driver to fail. Since commit 81ea00838c68 ("efi_loader: PSCI reset and shutdown") was added, which moves the PSCI EFI system reset handler into the PSCI driver, this has prevented the EFI system reset from working for Tegra210 and Tegra186. Therefore, populating these nodes is necessary to fix the EFI system reset for Tegra210 and Tegra186.
