From 645d81b886484e689527e4f23ab8ff10133d7664 Mon Sep 17 00:00:00 2001 From: Karel Balej Date: Thu, 28 Aug 2025 11:49:04 +0200 Subject: [PATCH] arm64: dts: samsung,coreprimevelte: add SDIO MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Set some basic properties of the SDIO card of the samsung,coreprimevelte smartphone. The SDIO is used as an interface for WiFi, Bluetooth and FM radio serviced by the Marvell 88W8777 (SD8777) chipset. Support for this chipset is currently not in-tree because the firmware is not available in linux-firmware, however it is possible to trivially run it out-of-tree using the mwifiex and Marvell Bluetooth drivers with some caveats.
