| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

The code now tries to preserve the mappings of the kernel so that master aborts for devices are avoided. Master aborts cause some devices to fail in the kdump kernel, so this code makes the dump more likely to succeed when AMD IOMMU is enabled. - common flush queue implementation for IOVA code users. The code is still optional, but AMD and Intel IOMMU drivers had their own implementation which is now unified. - finish support for iommu-groups. All drivers implement this feature now so that IOMMU core code can rely on it. - finish support for 'struct iommu_device' in iommu drivers. All drivers now use the interface. - new functions in the IOMMU-API for explicit IO/TLB flushing. This will help to reduce the number of IO/TLB flushes when IOMMU drivers support this interface. - support for mt2712 in the Mediatek IOMMU driver - new IOMMU driver for QCOM hardware - system PM support for ARM-SMMU - shutdown method for ARM-SMMU-v3 - some constification patches - various other small improvements and fixes" * tag 'iommu-updates-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (87 commits) iommu/vt-d: Don't be too aggressive when clearing one context entry iommu: Introduce Interface for IOMMU TLB Flushing iommu/s390: Constify iommu_ops iommu/vt-d: Avoid calling virt_to_phys() on null pointer iommu/vt-d: IOMMU Page Request needs to check if address is canonical. arm/tegra: Call bus_set_iommu() after iommu_device_register() iommu/exynos: Constify iommu_ops iommu/ipmmu-vmsa: Make ipmmu_gather_ops const iommu/ipmmu-vmsa: Rereserving a free context before setting up a pagetable iommu/amd: Rename a few flush functions iommu/amd: Check if domain is NULL in get_domain() and return -EBUSY iommu/mediatek: Fix a build warning of BIT(32) in ARM iommu/mediatek: Fix a build fail of m4u_type iommu: qcom: annotate PM functions as __maybe_unused iommu/pamu: Fix PAMU boot crash memory: mtk-smi: Degrade SMI init to module_init iommu/mediatek: Enlarge the validate PA range for 4GB mode iommu/mediatek: Disable iommu clock when system suspend iommu/mediatek: Move pgtable allocation into domain_alloc iommu/mediatek: Merge 2 M4U HWs into one iommu domain ...

Thus, currently subsys_initcall for SMI is unnecessary, SMI will be always probe defered by power-domain. Degrade it to module_init. In addition, there are two small changes about the probe sequence: 1) Delete this two lines. if (!dev->pm_domain) return -EPROBE_DEFER; This is not helpful. the platform driver framework guarantee this. The "dev_pm_domain_attach" in the "platform_drv_probe" will return EPROBE_DEFER if its powerdomain is not ready. 2) Add the probe-defer for the smi-larb device should waiting for smi-common. In mt2712, there are 2 smi-commons, 10 smi-larbs. All will be probe-defered by the power-domain, there is seldom case that smi-larb probe done before smi-common. then it will hang like this: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = ffffff800a4e0000 [00000000] *pgd=00000000beffe003[ 17.610026] , *pud=00000000beffe003 ...

The difference is that there are 2 M4U HWs in mt2712 while there's only one in mt8173. The purpose of 2 M4U HWs is for balance the bandwidth. Normally if there are 2 M4U HWs, there should be 2 iommu domains, each M4U has a iommu domain. Signed-off-by: Yong Wu <yong.wu@mediatek.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>

* | | memory: atmel-ebi: Allow t_DF timings of zero nsAlexander Dahl2017-07-261-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported in [1] and in [2] it's not possible to set the device tree property 'atmel,smc-tdf-ns' to zero, although the SoC allows a setting of 0ns for the t_DF time. Allow this setting by doing the same thing as in the atmel nand controller driver by setting ncycles to ATMEL_SMC_MODE_TDF_MIN if zero is set in the dts.

* | | memory: atmel-ebi: Fix smc timing return value evaluationAlexander Dahl2017-07-261-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting optional EBI/SMC properties through device tree always fails due to wrong evaluation of the return value of atmel_ebi_xslate_smc_timings(). If you put some of those properties in your dts file, but not 'atmel,smc-tdf-ns' the local variable 'required' in atmel_ebi_xslate_smc_timings() stays on 'false' after the first 'if' block. This leads to setting 'ret' to -EINVAL in the first run of the following 'for' loop which is then the return value of this function. However if you set 'atmel,smc-tdf-ns' in the dts file and everything in atmel_ebi_xslate_smc_timings() works well, it returns the content of 'required' which is 'true' then. So the function atmel_ebi_xslate_smc_timings() always returns non-zero which lets its call in atmel_ebi_xslate_smc_config() always fail and thus returning -EINVAL, so the EBI configuration for this node fails. Judging from the following code evaluating the local 'required' variable in atmel_ebi_xslate_smc_config() and the call of caps->xlate_config in atmel_ebi_dev_setup() it's probably right to only let the call fail if a negative error code is returned.
