Subject: [PATCH rtw-next 3/7] wifi: rtw89: 8922d: support new digital power compensation format
Date: Wed, 20 May 2026 20:38:19 +0800	[thread overview]
Message-ID: <20260520123823.1792954-4-pkshih@realtek.com> (raw)
In-Reply-To: <20260520123823.1792954-1-pkshih@realtek.com>

The new format shared the base set (7 elements). As there are total 40
sets, save 7 * 39 elements.
