Rename the driver and all relevant identifiers from Rockchip to Hantro,
as other Hantro IP based VPU implementations can be supported by the
same driver.
The RK3288 decoder is Hantro G1 based, the encoder is Hantro H1.
This patch just renames, no functional changes.

If a task is removing the block group that currently has the highest start
offset amongst all existing block groups, there is a short time window
where it races with a concurrent block group allocation, resulting in a
transaction abort with an error code of EEXIST.
The following diagram explains the race in detail:
Task A Task B
btrfs_remove_block_group(bg offset X)
remove_extent_mapping(em offset X)
-> removes extent map X from the
tree of extent maps
(fs_info->mapping_tree), so the
next call to find_next_chunk()
will return offset X
btrfs_alloc_chunk()
find_next_chunk()
--> returns offset X
__btrfs_alloc_chunk(offset X)
btrfs_make_block_group()
btrfs_create_block_group_cache()
--> creates btrfs_block_group_cache
object with a key corresponding
to the block group item in the
extent, the key is:
(offset X, BTRFS_BLOCK_GROUP_ITEM_KEY, 1G)
--> adds the btrfs_block_group_cache object
to the list new_bgs of the transaction
handle
btrfs_end_transaction(trans handle)
__btrfs_end_transaction()
btrfs_create_pending_block_groups()
--> sees the new btrfs_block_group_cache
in the new_bgs list of the transaction
handle
--> its call to btrfs_insert_item() fails
with -EEXIST when attempting to insert
the block group item key
(offset X, BTRFS_BLOCK_GROUP_ITEM_KEY, 1G)
because task A has not removed that key yet
--> aborts the running transaction with
error -EEXIST
btrfs_del_item()
-> removes the block group's key from
the extent tree, key is
(offset X, BTRFS_BLOCK_GROUP_ITEM_KEY, 1G)

When using the Hash Page Table (HPT) MMU, userspace memory mappings
are managed at two levels. Firstly in the Linux page tables, much like
other architectures, and secondly in the SLB (Segment Lookaside
Buffer) and HPT. It's the SLB and HPT that are actually used by the
hardware to do translations.
As part of the series adding support for 4PB user virtual address
space using the hash MMU, we added support for allocating multiple
"context ids" per process, one for each 512TB chunk of address space.
These are tracked in an array called extended_id in the mm_context_t
of a process that has done a mapping above 512TB.
If such a process forks (ie. clone(2) without CLONE_VM set) it's mm is
copied, including the mm_context_t, and then init_new_context() is
called to reinitialise parts of the mm_context_t as appropriate to
separate the address spaces of the two processes.
The key step in ensuring the two processes have separate address
spaces is to allocate a new context id for the process, this is done
at the beginning of hash__init_new_context(). If we didn't allocate a
new context id then the two processes would share mappings as far as
the SLB and HPT are concerned, even though their Linux page tables
would be separate.
For mappings above 512TB, which use the extended_id array, we
neglected to allocate new context ids on fork, meaning the parent and
child use the same ids and therefore share those mappings even though
they're supposed to be separate. This can lead to the parent seeing
writes done by the child, which is essentially memory corruption.
There is an additional exposure which is that if the child process
exits, all its context ids are freed, including the context ids that
are still in use by the parent for mappings above 512TB. One or more
of those ids can then be reallocated to a third process, that process
can then read/write to the parent's mappings above 512TB. Additionally
if the freed id is used for the third process's primary context id,
then the parent is able to read/write to the third process's mappings
*below* 512TB.
All of these are fundamental failures to enforce separation between
processes. The only mitigating factor is that the bug only occurs if a
process creates mappings above 512TB, and most applications still do
not create such mappings.
Only machines using the hash page table MMU are affected, eg. PowerPC
970 (G5), PA6T, Power5/6/7/8/9. By default Power9 bare metal machines
(powernv) use the Radix MMU and are not affected, unless the machine
has been explicitly booted in HPT mode (using disable_radix on the
kernel command line). KVM guests on Power9 may be affected if the host
or guest is configured to use the HPT MMU. LPARs under PowerVM on
Power9 are affected as they always use the HPT MMU. Kernels built with
PAGE_SIZE=4K are not affected.
The fix is relatively simple, we need to reallocate context ids for
all extended mappings on fork.

On buses like SlimBus and SoundWire which does not support
gather_writes yet in regmap, A bulk write on paged register
would be silently ignored after programming page.
This is because local variable 'ret' value in regmap_raw_write_impl()
gets reset to 0 once page register is written successfully and the
code below checks for 'ret' value to be -ENOTSUPP before linearising
the write buffer to send to bus->write().
Fix this by resetting the 'ret' value to -ENOTSUPP in cases where
gather_writes() is not supported or single register write is
not possible.

If an edge interrupt triggers while entering idle just before we save
GPIO datain register to saved_datain, the triggered GPIO will not be
noticed on wake-up. This is because the saved_datain and GPIO datain
are the same on wake-up in omap_gpio_unidle(). Let's fix this by
ignoring any pending edge interrupts for saved_datain.
This issue affects only idle states where the GPIO module internal
wake-up path is operational. For deeper idle states where the GPIO
module gets powered off, Linux generic wakeirqs must be used for
the padconf wake-up events with pinctrl-single driver. For examples,
please see "interrupts-extended" dts usage in many drivers.
This issue can be somewhat easily reproduced by pinging an idle system
with smsc911x Ethernet interface configured IRQ_TYPE_EDGE_FALLING. At
some point the smsc911x interrupts will just stop triggering. Also if
WLCORE WLAN is used with EDGE interrupt like it's documentation specifies,
we can see lost interrupts without this patch.
Note that in the long run we may be able to cancel entering idle by
returning an error in gpio_omap_cpu_notifier() on pending interrupts.
But let's fix the bug first.
Also note that because of the recent clean-up efforts this patch does
not apply directly to older kernels. This does fix a long term issue
though, and can be backported as needed.

drive development of drivers for this hardware upstream.
The current implementation has architectural flaws and would
need to be revamped using real hardware to something that can
reuse existing kernel abstractions in the subsystems for e.g.
I2C, FPGA and GPIO.
We have concluded that for the mainline kernel it will be
better to delete the subsystem and start over with a clean
slate when/if an active maintainer steps up.

If CONFIG_I2C is m and CONFIG_I2C_SLAVE is y,
building with CONFIG_IPMB_DEVICE_INTERFACE setting to
y will fail:

Add I2C Kconfig dependency to fix this.

The Allwinner V3 SoC, despite come with the same die with V3s, has more
GPIO pins than V3s, and a different compatible string for pinctrl is
needed.
Add the compatible string for V3 pinctrl.

The pinctrl driver of V3s is already available and used in the kernel,
but the compatible string of it is forgotten to be added.
Add the missing compatible string.
