Subject: [PATCH] iommu/io-pgtable: Make IOMMU_IO_PGTABLE_DART invisible
Date:   Tue, 27 Sep 2022 15:36:01 +0200
Message-Id: <b0981cb5a97452af73b9dd0dd0eb03c5002f7af4.1664285626.git.geert+renesas@glider.be>

There is no point in asking the user about both "Apple DART Formats" and
"Apple DART IOMMU Support", as the former is useless without the latter,
and the latter auto-selects the former.

Fixes: 745ef1092bcfcf3b ("iommu/io-pgtable: Move Apple DART support to its own file")

Should IOMMU_IO_PGTABLE_LPAE and IOMMU_IO_PGTABLE_ARMV7S be made
invisible, too?
Are there users that do not select them?
