From mboxrd@z Thu Jan 1 00:00:00 1970 From: thierry.reding@gmail.com (Thierry Reding) Date: Mon, 12 Nov 2018 16:18:51 +0100 Subject: [PATCH v2 08/10] arm64: tegra: Add nodes for TCU on Tegra194 In-Reply-To: <20181112151853.29289-1-thierry.reding@gmail.com> References: <20181112151853.29289-1-thierry.reding@gmail.com> Message-ID: <20181112151853.29289-9-thierry.reding@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Mikko Perttunen Add nodes required for communication through the Tegra Combined UART. This includes the AON HSP instance, addition of shared interrupts for the TOP0 HSP instance, and finally the TCU node itself. Also mark the HSP instances as compatible to tegra194-hsp, as the hardware is not identical but is compatible to tegra186-hsp.
