When a passthrough IO adapter is removed from a pseries machine using
hash MMU and the XIVE interrupt mode, the POWER hypervisor expects the
guest OS to clear all page table entries related to the adapter. If
some are still present, the RTAS call which isolates the PCI slot
returns error 9001

I've put this in my fixes branch.

When we enter into fadump crash path via system reset we fail to update
the pstore.
On the system reset path we first update the pstore then we go for fadump
crash. But the problem here is when all the CPUs try to get the pstore
lock to initiate the pstore write, only one CPUs will acquire the

The one difference on imx6sx platform is that the root clock
is shared with ASRC module, so we add a new flags
"shared_root_clock" which means the root clock is not independent,
then we will not do the clk_set_rate and clk_round_rate to avoid
impact ASRC module usage.
As add a new flags, we
Add new compatible string "fsl,imx6sx-spdif" in the binding document.
And add compatible string "fsl,vf610-spdif" which was missed before.
