From cefcf74ae02623a80acffe5f662ed6523575ed46 Mon Sep 17 00:00:00 2001 From: Zong-Zhe Yang Date: Thu, 10 Jul 2025 12:24:23 +0800 Subject: [PATCH] wifi: rtw89: 8852b: implement RFK multi-channel handling and support chanctx up to 2 To support multiple channels, 2 for this case, RFK requires to record each calibration result for each channel in different RFK tables, and also needs to notify FW. Then, when FW runs in MCC (multi-channel concurrency), it can switch to the corresponding calibration result according to the channel.
