From: Suman Anna Date: Tue, 27 Aug 2019 00:14:52 +0000 (-0500) Subject: ARM: OMAP2+: Add pdata for OMAP3 ISP IOMMU X-Git-Tag: v5.15~5255^2~3^2~1 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=0af3e1a491dde06dfcb0b063d5b543dfebded0f9;p=mirror_ubuntu-kernels.git ARM: OMAP2+: Add pdata for OMAP3 ISP IOMMU The OMAP3 ISP IOMMU does not have any reset lines, so it didn't need any pdata previously. The OMAP IOMMU driver now requires the platform data ops for device_enable/idle on all the IOMMU devices after commit db8918f61d51 ("iommu/omap: streamline enable/disable through runtime pm callbacks") to enable/disable the clocks properly and maintain the reference count and the omap_hwmod state machine. So, add these callbacks through iommu pdata quirks for the OMAP3 ISP IOMMU.
