Subject: [PATCH 0/2] OMAP IOMMU fixes to go with 5.4 OMAP IOMMU changes
Date: Mon, 26 Aug 2019 19:14:50 -0500 [thread overview]
Message-ID: <20190827001452.31930-1-s-anna@ti.com> (raw)
Hi Tony,
The following 2 patches need to go along with the recent "iommu/omap: misc
fixes" series [1] that is currently staged [2] for a 5.4 merge and available
in linux-next. That series added runtime pm callbacks in preparation for
the ti-sysc migration, but without adding the necessary platform data
callbacks for the existing functional MMUs on OMAP3, OMAP4 and OMAP5 SoCs.
These 2 patches add the same to maintain the functionality (l3_noc errors
are the visible symptom while enabling the MMUs without these patches).
OMAP4 and OMAP5 would also need another set of fixes related to the
breakage caused by the switch to clkctrl clocks as seen in [3].
These patches do have a dependency on the staged patches, so either you
submit a pull-request towards 5.4-rc2 using 5.4-rc1 baseline, or let
Joerg pick these through the arm/omap IOMMU branch for 5.4-rc1 itself.
Sakari/Laurent,
Appreciate it if you can check the OMAP3 ISP functionality on latest
linux-next with the second patch. I have verified the ISP MMU programming
only through an unit-test.
Tero,
I will be submitting another patch against OMAP IOMMU driver to skip the
pdata callbacks for ti-sysc in the next couple of days.
regards
Suman
