sequence for both rddm and fw download are initialized to be 0.
They are incremented by 1 in bhi_probe() and upon real transfer
takes place.
Issue is in SSR case, sequence is incrementing in a way like 1,
3, 5 and etc as observed. The increment in bhi_probe() seems
unnecessay as there's no real transfer.
Fix is to initialize sequence to 1 and increment by 1 when real
transfer takes place in bhi_bhie_transfer().

Add memory-hotplug support for ARM64 platform.
This requires addition of
ARCH_ENABLE_MEMORY_HOTPLUG and ARCH_ENABLE_MEMORY_HOTREMOVE config options.
MEMORY_PROBE config option is added to support

In addition architecture specific arch_add_memory and

As per the hardware programming sequence, HDCP authentication
process must start after turning ON the timing engine and the
authentication process should be stopped before turning OFF
the timing engine.
Implement this sequence during the HDMI turn OFF sequence.
Also, make sure to wait for one frame before disabling the DDC
while turning OFF the HDCP. This is required to make sure we
receive the HDCP encryption disabled interrupt before disabling
the HW.

When getting string from userspace by simple_write_to_buffer
in ufs_qcom_dbg_testbus_cfg_write() function, null byte may
be written out of bounds of configuration buffer if return
value is same as size of buffer, causing off-by-one bug.
This change passes correct available size of configuration
buffer to simple_write_to_buffer function.

When SSR happending during WLAN interface up, a deadlock will happen
in many places where it waits for FW response. When wlan module starts,
it will hold a rtnl_lock and wait for FW response. If SSR happened at
this point, it will send ssr notification to all the registed modules
one by one. It will send notification to IPA first, which will also
tried to get a hold of rtnl_lock. Since ssr notification is synchronized,
IPA won't be able to return because of failing to acquire the lock and
wlan driver won't release the rtnl_lock until it timeout and crash.
Only graceful to avoid this deadlock is to get early modem
crash notification from platform via a path which does not acquire
RTNL lock and this way once driver has received early crash
notification it can reject interface up.
Modem notification comes to icnss before IPA, hence send
early crash notification in modem SSR handler so that wlan driver
can release RTNL lock as soon as possible.

Currently when pd is disabled, we do not allow hvdcp. To fix that
once hvdcp timeout happens and if pd is disabled, force a pd_active
= 0. This will cause us to run legacy workaround and rerun apsd if
the charger was detected as hvdcp.
Importantly, once legacy bit workaround is run, wait 400mS for
typeC to debounce. Currently we wait for 100mS only and that
causes a removal detection since the CC lines are not settled within
100mS.
Also it may take up to 650mS for the vbus to drop once CC lines are
floated during the workaround. The current wait is just 500mS,
bump it up to a 1 second.

(from https://patchwork.kernel.org/patch/10058587/)
proc->files cleanup is initiated by binder_vma_close. Therefore
a reference on the binder_proc is not enough to prevent the
files_struct from being released while the binder_proc still has
a reference. This can lead to an attempt to dereference the
stale pointer obtained from proc->files prior to proc->files
cleanup. This has been seen once in task_get_unused_fd_flags()
when __alloc_fd() is called with a stale "files".
The fix is to always use get_files_struct() to obtain struct_files
so that the refcount on the files_struct is used to prevent
a premature free. proc->files is removed since we get it every
time.

When doing WLAN SSR tests on Rome PCIe platform, system hang
is observed. After debugging, setting D3hot to PCIe link when
suspending leads to the hang.
Setting D3hot is a new change, which is added for Napier platform.
But this code path shares with legacy Rome platform. In previous
implementations for Rome PCIe platforms, setting D3hot to link
is not needed.
Fix is to set D3hot for Napier specific platforms.
