Subject: [PATCH v10 07/12] soc: mediatek: Remove infracfg misc driver support
Date: Wed, 18 Dec 2019 16:30:43 +0800 [thread overview]
Message-ID: <1576657848-14711-8-git-send-email-weiyi.lu@mediatek.com> (raw)
In-Reply-To: <1576657848-14711-1-git-send-email-weiyi.lu@mediatek.com>
In previous patches, we introduce scpsys-ext driver that covers
the functions which infracfg misc driver provided.
And then replace bus_prot_mask with bp_table of all compatibles.
Now, we're going to remove infracfg misc drvier which is no longer
being used.
