Subject: [PATCH v3 25/33] iommu/mediatek: Just move code position in hw_init
Date: Thu, 23 Sep 2021 19:58:32 +0800 [thread overview]
Message-ID: <20210923115840.17813-26-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210923115840.17813-1-yong.wu@mediatek.com>
No functional change too, prepare for mt8195 IOMMU support bank functions.
Some global control settings are in bank0 while the other banks have
their bank independent setting. Here only move the global control
settings and the independent registers together.
