From 9cf3415ade2d7598d78d2ce6d35d6d6d06132201 Mon Sep 17 00:00:00 2001 From: Martin Botka Date: Thu, 18 Apr 2024 16:44:01 +0100 Subject: [PATCH] firmware: smccc: Export revision soc_id function The "SoC ID revision" as provided via the SMCCC SOCID interface can be valuable information for drivers, when certain functionality depends on a die revision, for instance. One example is the sun50i-cpufreq-nvmem driver, which needs this information to determine the speed bin of the SoC. Export the arm_smccc_get_soc_id_revision() function so that it can be called by any driver.
