Subject: [PATCH 17/24] iommu/mediatek: Just move code position in hw_init
Date: Wed, 30 Jun 2021 10:34:57 +0800	[thread overview]
Message-ID: <20210630023504.18177-18-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210630023504.18177-1-yong.wu@mediatek.com>

No functional change too. mt8195 IOMMU support bank functions.
some global control etting is in bank0. and the other banks have its
bank independent setting. this patch only moves the control settings
and the independent registers together.
