Subject: [PATCH v4 13/17] iommu/mediatek: Use module_platform_driver
Date: Sat, 30 May 2020 16:10:14 +0800	[thread overview]
Message-ID: <1590826218-23653-14-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1590826218-23653-1-git-send-email-yong.wu@mediatek.com>

MediaTek IOMMU should wait for smi larb which need wait for the
power domain(mtk-scpsys.c) and the multimedia ccf, both are module
init. Thus, subsys_initcall for MediaTek IOMMU is not helpful.
Switch to module_platform_driver.

Correspondingly, add the module license information.

for iommu v1: honghui's mail address is not valid now. I will be
responsible for that file too, So I add myself in it.
