False positive reset would be possibly triggered by those commands we
applied in suspend with HZ MCU timeout, especially it happened when we
enabled kernel log in pm core to diagnose how much time we spend in each
driver during suspend procedure. So we enlarge the value and align the MCU
timeout as other commands we did to reduce the false positive reset.

Given that there's no data coming from network stack for binding flows,
hence driver counts and reports station's statistics directly through
NL80211_STA_INFO_* based on active PPDU based TxS for offloading data.
Apart from that, WA firmware and its offloading engine (SDO) have hardcoded
"2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting.
Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST.

Thus, the suspend procedure should be waiting until the reset is completed

The DMA subsystem could be entirely disabled in Kconfig and then the

fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable
dependency.
The FUSE driver isn't a critical driver and currently it only provides
NVMEM interface to userspace which isn't known to be widely used, and
thus, it's fine if FUSE driver fails to load.
Let's remove the erroneous Kconfig dependency and let the FUSE driver to

Adding driver to handle errors from CBB version 2.0 which is used in
Tegra234 SoC. The driver prints debug information about failed
transaction on receiving interrupt from the error notifier. The error
notifier collates the interrupts from various error monitor blocks and
presents a single interrupt to the SoC interrupt controller.
For timeout errors, the driver also does the lookup to find timed out
clients and prints their client ID. Drivers for hardware that needs to
be reset on timeout will have to call BPMP from the client IP's driver.
BPMP firmware will also clear the timeout bit after resetting the IP
so that next transactions are send to them after reset.
