From 74c116df66d25a9fb48d44ce545a505edc5fbbba Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 7 Aug 2019 11:26:46 +0300 Subject: [PATCH] iommu/omap: add pdata ops for omap_device_enable/idle Add two new platform data ops to allow the OMAP iommu driver to be able to invoke the omap_device_enable and omap_device_idle from within the driver. These are being added to streamline the sequence between managing the hard reset lines and the clocks during the suspend path, as the default device pm_domain callback sequences in omap_device layer are not conducive for the OMAP IOMMU driver. This could have been done by expanding the existing pdata ops for reset management (like in the OMAP remoteproc driver), but this was chosen to avoid adding additional code in the separate file in the mach-omap2 layer.
