Subject: [PATCH v3 28/33] iommu/mediatek: Add bank_nr and bank_enable
Date: Thu, 23 Sep 2021 19:58:35 +0800 [thread overview]
Message-ID: <20210923115840.17813-29-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210923115840.17813-1-yong.wu@mediatek.com>
Prepare for supporting multi banks, Adds two variables in the plat_data:
bank_nr: the bank number that this SoC support;
bank_enable: list if the banks is enabled.
Add them for all the current SoC, bank_nr always is 1 and only
bank_enable[0] is enabled.
