From 472c46f9a617348fa8a8ba19dc50e1727c95a58e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=8D=C3=B1igo=20Huguet?= Date: Wed, 24 May 2023 15:00:27 +0200 Subject: [PATCH 048/142] wifi: rtw89: move enable_cpu/disable_cpu into fw_download MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bugzilla: https://bugzilla.redhat.com/2207499 commit 5f05bdb0a770b5d03d3453c0b0743bb3dcd1a2ba Author: Chih-Kang Chang Date: Thu Oct 27 13:27:02 2022 +0800 wifi: rtw89: move enable_cpu/disable_cpu into fw_download For WoWLAN mode, we need to download WoWLAN firmware by calling fw_download(). Another, to disable/enable WiFi CPU is needed before calling fw_download. Since Firmware runs on WiFi CPU, it is intuitive to combine enable_cpu/disable_cpu functions into fw_download.
