Subject: [PATCH v8 00/14] iommu/rockchip: Use OF_IOMMU
Date: Fri, 23 Mar 2018 15:38:00 +0800 [thread overview]
Message-ID: <20180323073814.5802-1-jeffy.chen@rock-chips.com> (raw)
This series fixes some issues in rockchip iommu driver, and add of_iommu
support in it.
Changes in v8:
Rebase on newest for-next.
Don't introduce the additional return.
Rename startup()/shutdown() to enable()/disable().
Do runtime PM suspend in .shutdown().
Modify pm_runtime_get_if_in_use()/pm_runtime_put() as Tomasz suggested.
Changes in v7:
Use iommu_group_ref_get to avoid ref leak
Changes in v6:
Add clk names, and modify all iommu nodes in all existing rockchip dts
Fix dt-binding as Robin suggested.
Use aclk and iface clk as Rob and Robin suggested, and split binding
patch.
Changes in v5:
Use out labels to save the duplication between the error and success paths.
Use RK_MMU_POLL_PERIOD_US instead of 100.
Remove clk names.
Use clk_bulk APIs.
Avoid race about pm_runtime_get_if_in_use() and pm_runtime_enabled().
Changes in v4:
Rewrite commit message.
Changes in v3:
Also remove remove() and module_exit() as Tomasz suggested.
Loop platform_get_irq() as Robin suggested.
Add struct rk_iommudata.
Squash iommu/rockchip: Use iommu_group_get_for_dev() for add_device
Only call startup() and shutdown() when iommu attached.
Remove pm_mutex.
Check runtime PM disabled.
Check pm_runtime in rk_iommu_irq().
Remove rk_iommudata->domain.
Changes in v2:
Move irq request to probe(in patch[0])
Move bus_set_iommu() to rk_iommu_probe().
Jeffy Chen (10):
iommu/rockchip: Prohibit unbind and remove
iommu/rockchip: Fix error handling in probe
iommu/rockchip: Request irqs in rk_iommu_probe()
ARM: dts: rockchip: add clocks in iommu nodes
dt-bindings: iommu/rockchip: Add clock property
iommu/rockchip: Use IOMMU device for dma mapping operations
iommu/rockchip: Use OF_IOMMU to attach devices automatically
iommu/rockchip: Fix error handling in init
iommu/rockchip: Add runtime PM support
iommu/rockchip: Support sharing IOMMU between masters
Tomasz Figa (4):
iommu/rockchip: Fix error handling in attach
iommu/rockchip: Use iopoll helpers to wait for hardware
iommu/rockchip: Fix TLB flush of secondary IOMMUs
iommu/rockchip: Control clocks needed to access the IOMMU
