Subject: [PATCH 12/12] clk: mediatek: limit en_mask to a pure div_en_mask
Date: Thu, 22 Oct 2020 20:56:05 +0800 [thread overview]
Message-ID: <1603371365-30863-13-git-send-email-weiyi.lu@mediatek.com> (raw)
In-Reply-To: <1603371365-30863-1-git-send-email-weiyi.lu@mediatek.com>
Because all pll data has been updated. We no longer allow
en_mask is a combination of pll_en_bit and div_en_mask.
