Subject: [GIT PULL] iommu/arm-smmu: Updates for 5.5
Date: Thu, 7 Nov 2019 14:30:20 +0000	[thread overview]
Message-ID: <20191107143020.GA12988@willie-the-truck> (raw)

Hi Joerg,

Please pull these Arm SMMU updates for 5.5. The main changes are support
for the Qualcomm SMMUv2 implementation in the SDM845 SoC using the recently
introduced "implementation hook" code, a bunch of preparatory work to
expose TTBR1 via the io-pgtable code so that two (distinct) page tables
can be attached to a domain at the same time and performance improvements
relating to runtime power management on SMMUv2 during unmap() and general
dispatch of the new TLB invalidation callbacks.

The Qualcomm patches necessitated some changes to their firmware interface
code, but that has been Acked by Andy and Bjorn.

There were some conflicts with the fixes I sent you previously, so this
branch has those same commits merged in because I didn't want to rebase.




The following changes since commit 1be08f458d1602275b02f5357ef069957058f3fd:

  iommu/io-pgtable-arm: Support all Mali configurations (2019-10-01 12:16:47 +0100)
