To simplify with maintenance let's move the powergate-bpmp driver to the
new genpd directory. Going forward, patches are intended to be managed
through a separate git tree, according to MAINTAINERS.
Note that, we leave the pmc driver in the soc directory for now, as it
looks like it may need some re-structuring before it's ready to be moved.

Move to the device-managed version of clk_notifier_register() to remove
the need for manual cleanup. This fixes a potential issue where the
clock notifier would stick around after the driver fails to probe at a
later point.

debugfs calls should generally not be error-checked to simplify the case
where debugfs is disabled. Since this driver is built-in and has the
sysfs bind/unbind attributes disabled, it cannot be unloaded, so there
is no need to hold onto a reference to the debugfs files that are
created.
We can further simplify this by moving the debugfs file creation to a
later stage to avoid any cleanup we might have to do during error unwind
operations. This is also a little cleaner because the debugfs file
relies on data structures that are created at a later point than when
the file was previously created.

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as

To enable error reporting for a fabric to CCPLEX, we need to write its
register for enabling error interrupt to CCPLEX during boot and later
clear the error status register after error occurs. If a fabric's
registers are protected and not accessible from CCPLEX, then accessing
the registers will cause CBB firewall error.
Add support to check whether write access from CCPLEX to the registers
of a fabric is not blocked by it's firewall before enabling error
reporting to CCPLEX for that fabric.

In Tegra194 SoC, master_id bit range is different between cluster NOC
and CBB NOC. Currently same bit range is used which results in wrong
master_id value. Due to this, illegal accesses from the CCPLEX master
do not result in a crash as expected. Fix this by using the correct
range for the CBB NOC.
Finally, it is only necessary to extract the master_id when the
erd_mask_inband_err flag is set because when this is not set, a crash
is always triggered.

When a wake event is defined to be triggered on both positive and
negative edge of the input wake signal, it is crucial to know the
current state of the signal when going into suspend. The intended way to
obtain the current state of the wake signals is to read the
WAKE_AOWAKE_SW_STATUS register, which should contains the raw state of
the wake signals.
However, this register is edge triggered, an edge will not be generated
for signals that are already asserted prior to the assertion of
WAKE_LATCH_SW.
To workaround this, change the polarity of the wake level from '0' to
'1' while latching the signals, as this will generate an edge for
signals that are set to '1'.

The DMA subsystem could be entirely disabled in Kconfig and then the
TEGRA20_APB_DMA option isn't available too. Hence kernel configuration
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
fail the probing if DMA is unavailable.

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.
