commit 0e4cac557531a4c93de108d9ff11329fcad482ff upstream.
commit 101bd907b424 ("misc: rtsx: judge ASPM Mode to set PETXCFG Reg")
some readers no longer force #CLKREQ to low
when the system need to enter ASPM.
But some platform maybe not implement complete ASPM?
it causes some platforms can not boot
Like in the past only the platform support L1ss we release the #CLKREQ.
Move the judgment (L1ss) to probe,
we think read config space one time when the driver start is enough

[ Upstream commit aefc8b57af7787c80686e49a5841e9289cb11f53 ] On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let OPEN_DICE depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ERROR: modpost: "devm_memremap" [drivers/misc/open-dice.ko] undefined!

commit a2cb9cd6a3949a3804ad9fd7da234892ce6719ec upstream.
Scatterlist table is obtained during map create request and the same
table is used for DMA mapping unmap. In case there is any failure
while getting the sg_table, ERR_PTR is returned instead of sg_table.
When the map is getting freed, there is only a non-NULL check of
sg_table which will also be true in case failure was returned instead
of sg_table. This would result in improper unmap request. Add proper
check before setting map table to avoid bad unmap request.

commit ada6c2d99aedd1eac2f633d03c652e070bc2ea74 upstream.
Remote heap is used by DSP audioPD on need basis. This memory is
allocated from reserved CMA memory region and is then shared with
audioPD to use it for it's functionality.
Current implementation of remote heap is not allocating the memory
from CMA region, instead it is allocating the memory from SMMU
context bank. The arguments passed to scm call for the reassignment
of ownership is also not correct. Added changes to allocate CMA
memory and have a proper ownership reassignment.

commit fe6518d547fc52ba74201018dc9aeb364072ac78 upstream.
Memory is allocated for dynamic loading when audio daemon is trying
to attach to audioPD on DSP side. This memory is allocated from
reserved CMA memory region and needs ownership assignment to
new VMID in order to use it from audioPD.
In the current implementation, arguments are not correctly passed
to the scm call which might result in failure of dynamic loading
on audioPD. Added changes to pass correct arguments during daemon
attach request.

A previous commit tried to come up with more generic subpool
names, but this isn't quite working: the node name was used
elsewhere to match pools to consumers which regressed the
nVidia Tegra 2/3 video decoder.
Revert back to an earlier approach using of_node_full_name()
instead of just the name to make sure the pool name is more
unique, and change both sites using this in the kernel.
It is not perfect since two SRAM nodes could have the same
subpool name but it makes the situation better than before.
