From ebceec271e552a2b05e47d8ef0597052b1a39449 Mon Sep 17 00:00:00 2001 From: Yogesh Hegde Date: Tue, 18 Jul 2023 22:09:41 +0530 Subject: arm64: dts: rockchip: Fix Wifi/Bluetooth on ROCK Pi 4 boards This patch fixes an issue affecting the Wifi/Bluetooth connectivity on ROCK Pi 4 boards. Commit f471b1b2db08 ("arm64: dts: rockchip: Fix Bluetooth on ROCK Pi 4 boards") introduced a problem with the clock configuration. Specifically, the clock-names property of the sdio-pwrseq node was not updated to 'lpo', causing the driver to wait indefinitely for the wrong clock signal 'ext_clock' instead of the expected one 'lpo'. This prevented the proper initialization of Wifi/Bluetooth chip on ROCK Pi 4 boards. To address this, this patch updates the clock-names property of the sdio-pwrseq node to "lpo" to align with the changes made to the bluetooth node. This patch has been tested on ROCK Pi 4B.
