After extending v7s, our pagetable already support iova reach
16GB(34bit). the master got the iova via dma_alloc_attrs may reach
34bits, but its HW register still is 32bit. then how to set the
bit32/bit33 iova? this depend on a SMI larb setting(bank_sel).
we separate whole 16GB iova to four banks:
bank: 0: 0~4G; 1: 4~8G; 2: 8-12G; 3: 12-16G;
The bank number is (iova >> 32).
We will preassign which bank the larbs belong to. currently we don't
have a interface for master to adjust its bank number.
Each a bank is a iova_region which is a independent iommu-domain.
the iova range for each iommu-domain can't cross 4G.

[ Upstream commit 94e9dd43cf ]
Call of_node_put() to decrement the reference count of the child node
child_np when jumping out of the loop body of
for_each_available_child_of_node(), which is a macro that increments and
decrements the reference count of child node. If the loop is broken, the
reference of the child node should be dropped manually.

Pull iommu updates from Joerg Roedel:
- ARM-SMMU Updates from Will:
- Continued SVM enablement, where page-table is shared with CPU
- Groundwork to support integrated SMMU with Adreno GPU
- Allow disabling of MSI-based polling on the kernel command-line
- Minor driver fixes and cleanups (octal permissions, error
messages, ...)
- Secure Nested Paging Support for AMD IOMMU. The IOMMU will fault when
a device tries DMA on memory owned by a guest. This needs new
fault-types as well as a rewrite of the IOMMU memory semaphore for
command completions.
- Allow broken Intel IOMMUs (wrong address widths reported) to still be
used for interrupt remapping.
- IOMMU UAPI updates for supporting vSVA, where the IOMMU can access
address spaces of processes running in a VM.
- Support for the MT8167 IOMMU in the Mediatek IOMMU driver.
- Device-tree updates for the Renesas driver to support r8a7742.

Previously, devfreq core support 'devfreq-events' property in order to get
the devfreq-event device by phandle. But, 'devfreq-events' property name is
not proper on devicetree binding because this name doesn't mean
the any h/w attribute.
The devfreq-event core hand over the rights to decide the property name
for getting the devfreq-event device on devicetree. Each devfreq-event driver
will decide the property name on devicetree binding and then pass
the their own property name to devfreq_event_get_edev_by_phandle function.
And change the prototype of devfreq_event_get_edev_count function
because of used deprecated 'devfreq-events' property.

Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code.
Along with this change, we get additionally:
.owner = THIS_MODULE,
.llseek = seq_lseek,
1. The llseek method is used to change the current read/write position
in a file which can be ignored if you don't use it.
2. The owner is not even a method. Instead, it is a pointer to the
module that “owns” this structure; it is used by the kernel to maintain
the module's usage count which can be ignored.

Commit 63a613fdb1 ("memory: tegra: Add gr2d and gr3d to DRM IOMMU
group") added the GPU to the DRM IOMMU group, which doesn't make any
sense. This causes problems when Nouveau tries to attach to the SMMU
and causes it to fall back to using the DMA API.
Remove the GPU from the DRM groups to restore the old behaviour. The
GPU should always have its own IOMMU domain to make sure it can map
buffers into contiguous chunks (for big page support) without getting
in the way of mappings from the DRM group.

Callers are generally not supposed to check the return values from
debugfs functions. Debugfs functions never return NULL so this error
handling will never trigger. (Historically debugfs functions used to
return a mix of NULL and error pointers but it was eventually deemed too
complicated for something which wasn't intended to be used in normal
situations).
Delete all the error handling.

If CONFIG_OF is n, gcc fails:
drivers/memory/omap-gpmc.o: In function `gpmc_omap_onenand_set_timings':
omap-gpmc.c:(.text+0x2a88): undefined reference to `gpmc_read_settings_dt'
Add gpmc_read_settings_dt() helper function, which zero the gpmc_settings
so the caller doesn't proceed with random/invalid settings.

Add separate entry for Broadcom STB DPFE driver, enabled by default on
ARCH_BRCMSTB. This allows compile testing.

The GPMC_SET_ONE_CD_MAX macro uses return statement and variable 'cs'
coming from called scope. This is not a good practice. Also
checkpatch complained:
WARNING: Macros with flow control statements should be avoided
ERROR: Macros starting with if should be enclosed by a do - while
loop to avoid possible if/else logic defects
Since GPMC_SET_ONE_CD_MAX macro just calls one function, it can be open
coded. The difference with original code is that function will exit on
error not after every register set, but after a group of sets.

The callers of gpmc_cs_set_timings() expect to receive -ERRNO on errors
and they pass further what they have received.
However gpmc_cs_set_timings() was returning -1 (equal to -EPERM) which
does not make sense in this context.

The file-scope variables phys_base and mem_size are assigned in
gpmc_probe() but never read.
This fixes build error when compile testing on x86_64 architecture:

The driver does not use macros from asm/mach-types.h (neither MACH_TYPE
nor machine_is_xxx()). Removal of this include allows compile testing
on non-ARM architectures which lack this header.
