8d9be5c6bd remoteproc: qcom: q6v5: Add interconnect path proxy vote
Many remoteproc instances requires that Linux casts a proxy vote for an
interconnect path during boot, until they can do it themselves. Add
support for voting for a single path.

As this is a shared problem between both PAS and MSS drivers, the path
is acquired and votes casted from the common helper code.

The device_node pointer is returned by of_parse_phandle() or

We should use of_node_put() on it when done.

This function only call of_node_put(node) when of_address_to_resource

26c9da5194 remoteproc: Introduce sysfs_read_only flag
The remoteproc framework provides sysfs interfaces for changing
the firmware name and for starting/stopping a remote processor
through the sysfs files 'state' and 'firmware'. The 'coredump'
file is used to set the coredump configuration. The 'recovery'
sysfs file can also be used similarly to control the error recovery
state machine of a remoteproc. These interfaces are currently
allowed irrespective of how the remoteprocs were booted (like
remoteproc self auto-boot, remoteproc client-driven boot etc).
These interfaces can adversely affect a remoteproc and its clients
especially when a remoteproc is being controlled by a remoteproc
client driver(s). Also, not all remoteproc drivers may want to
support the sysfs interfaces by default.

Add support to make the remoteproc sysfs files read only by
introducing a state flag 'sysfs_read_only' that the individual
remoteproc drivers can set based on their usage needs. The default
behavior is to allow the sysfs operations as before.

Implement attribute_group->is_visible() to make the sysfs
entries read only when 'sysfs_read_only' flag is set.

eee412e968 remoteproc: qcom: q6v5: fix service routines build errors
When CONFIG_QCOM_AOSS_QMP=m and CONFIG_QCOM_Q6V5_MSS=y, the builtin
driver cannot call into the loadable module's low-level service
functions. Trying to build with that config combo causes linker errors.

There are two problems here. First, drivers/remoteproc/qcom_q6v5.c
should #include <linux/soc/qcom/qcom_aoss.h> for the definitions of
the service functions, depending on whether CONFIG_QCOM_AOSS_QMP is
set/enabled or not. Second, the qcom remoteproc drivers should depend
on QCOM_AOSS_QMP iff it is enabled (=y or =m) so that the qcom
remoteproc drivers can be built properly.

This prevents these build errors:

aarch64-linux-ld: drivers/remoteproc/qcom_q6v5.o: in function `q6v5_load_state_toggle':
qcom_q6v5.c:(.text+0xc4): undefined reference to `qmp_send'

Both: the application cores (A5x) and the realtime core (CR7)
share access to the RAM and devices with the same address map,
so device addresses are equal to the Linux physical addresses.

In order to initialize this remote processor we need to:
- power on the realtime core
- put the firmware in a RAM area
- set the boot address for this firmware (reset vector)
- Deassert the reset

This initial driver allows to start and stop the Cortex R7
processor.

c768968f13 remoteproc: ingenic: Request IRQ disabled
The ingenic remoteproc driver requests its IRQ and then immediately
disables it.

The disable is necessary since irq_request() normally enables the IRQ. But
there is a new flag IRQF_NO_AUTOEN that when specified keeps the IRQ
disabled. Use this new flag rather than calling disable_irq().

This slightly reduce the boilerplate code and also avoids a theoretical
race condition where the IRQ could fire between irq_request() and
disable_irq().

                dev_err(dev, "SRAM address contains unusable bits\n");

The problem is that "->sram_pa" is type phys_addr_t which is potentially
64 bits.  That means the MESON_AO_RPROC_SRAM_USABLE_BITS macro needs to
be a 64 bit type as well to ensure that high 32 bits are cleared.

6cb58ea897 remoteproc: meson-mx-ao-arc: Add a driver for the AO ARC remote procesor
Amlogic Meson6, Meson8, Meson8b and Meson8m2 embed an ARC core in the
Always-On (AO) power-domain. This is typically used for waking up the
ARM cores after system suspend.

The configuration is spread across three different registers:
- AO_REMAP_REG0 which must be programmed to zero, it's actual purpose
  is unknown. There is a second remap register which is not used in the
  vendor kernel (which served as reference for this driver).
- AO_CPU_CNTL is used to start and stop the ARC core.
- AO_SECURE_REG0 in the SECBUS2 register area with unknown purpose.

To boot the ARC core we also need to enable it's gate clock and trigger
a reset.

The actual code for this ARC core can come from an ELF binary, for
example by building the Zephyr RTOS for an ARC EM4 core and then taking
"zephyr.elf" as firmware. This executable does not have any "rsc table"
so we are skipping rproc_elf_load_rsc_table (rproc_ops.parse_fw) and
rproc_elf_find_loaded_rsc_table (rproc_ops.find_loaded_rsc_table).
