Subject: [PATCH v3 3/4] firmware: tegra: bpmp: Add Tegra238 support
Date: Mon, 2 Nov 2026 12:12:01 +0000 [thread overview]
Message-ID: <20261102121202.2431928-4-johnliu@nvidia.com> (raw)
In-Reply-To: <20261102121202.2431928-1-johnliu@nvidia.com>
Tegra238 has its own BPMP compatible, "nvidia,tegra238-bpmp". Add
dedicated tegra238_soc data for it, including its EMC clock ID
(TEGRA238_CLK_EMC=43), and select it through the new compatible.
Also build bpmp-tegra186.o and the shared match table for
CONFIG_ARCH_TEGRA_238_SOC, so that a Tegra238-only configuration binds
the driver.
