Since the series that fixes console probe delay based on stdout-path[1] got

Even if stdout-path isn't set in DT, this patch should take console

[PATCH v1 0/2] Fix console probe delay when stdout-path isn't set

[Saravana Kannan]

Since the series that fixes console probe delay based on stdout-path[1] got
pulled into driver-core-next, I made these patches on top of them.

Even if stdout-path isn't set in DT, this patch should take console
probe times back to how they were before the deferred_probe_timeout
clean up series[2].

Fabio/Ahmad/Sascha,

Can you give this a shot please?

[PATCH v1 1/2] driver core: Add probe_no_timeout flag for drivers

[Saravana Kannan]

This flag only needs to be set for drivers of devices that meet all the
following conditions:
- Need to probe successfully before userspace init in started
- Have optional suppliers
- Can't wait for deferred_probe_timeout to expire

fw_devlink=on uses this info, as needed, to ignore dependencies on supplier
devices that have not been added or supplier devices that don't have any
drivers.  It's still up to the driver to decide which of the missing
suppliers are optional or not.

[PATCH v1 1/2] driver core: Add probe_no_timeout flag for drivers

[Saravana Kannan]

This flag only needs to be set for drivers of devices that meet all the
following conditions:
- Need to probe successfully before userspace init in started
- Have optional suppliers
- Can't wait for deferred_probe_timeout to expire

fw_devlink=on uses this info, as needed, to ignore dependencies on supplier
devices that have not been added or supplier devices that don't have any
drivers.  It's still up to the driver to decide which of the missing
suppliers are optional or not.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")

[Saravana Kannan]

This flag only needs to be set for drivers of devices that meet all the
following conditions:
- Need to probe successfully before userspace init in started
- Have optional suppliers
- Can't wait for deferred_probe_timeout to expire

fw_devlink=on uses this info, as needed, to ignore dependencies on supplier
devices that have not been added or supplier devices that don't have any
drivers.  It's still up to the driver to decide which of the missing
suppliers are optional or not.

[Saravana Kannan]

This flag only needs to be set for drivers of devices that meet all the
following conditions:
- Need to probe successfully before userspace init in started
- Have optional suppliers
- Can't wait for deferred_probe_timeout to expire

fw_devlink=on uses this info, as needed, to ignore dependencies on supplier
devices that have not been added or supplier devices that don't have any
drivers.  It's still up to the driver to decide which of the missing
suppliers are optional or not.

[PATCH v1 2/2] serial: Set probe_no_timeout for all DT based drivers

[Saravana Kannan]

With commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by
default") the probing of TTY consoles could get delayed if they have
optional suppliers that are listed in DT, but those suppliers don't
probe by the time kernel boot finishes. The console devices will probe
eventually after driver_probe_timeout expires.

However, since consoles are often used for debugging kernel issues, it
does not make sense to delay their probe. So, set the newly added
probe_no_timeout flag for all serial drivers that at DT based. This way,
fw_devlink will know not to delay the probing of the consoles past
kernel boot.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")

[PATCH v1 2/2] serial: Set probe_no_timeout for all DT based drivers

[Saravana Kannan via iommu]

With commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by
default") the probing of TTY consoles could get delayed if they have
optional suppliers that are listed in DT, but those suppliers don't
probe by the time kernel boot finishes. The console devices will probe
eventually after driver_probe_timeout expires.

However, since consoles are often used for debugging kernel issues, it
does not make sense to delay their probe. So, set the newly added
probe_no_timeout flag for all serial drivers that at DT based. This way,
fw_devlink will know not to delay the probing of the consoles past
kernel boot.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")

[PATCH v1 2/2] serial: Set probe_no_timeout for all DT based drivers

[Saravana Kannan]

With commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by
default") the probing of TTY consoles could get delayed if they have
optional suppliers that are listed in DT, but those suppliers don't
probe by the time kernel boot finishes. The console devices will probe
eventually after driver_probe_timeout expires.

However, since consoles are often used for debugging kernel issues, it
does not make sense to delay their probe. So, set the newly added
probe_no_timeout flag for all serial drivers that at DT based. This way,
fw_devlink will know not to delay the probing of the consoles past
kernel boot.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")

[PATCH v1 2/2] serial: Set probe_no_timeout for all DT based drivers

[Saravana Kannan]

With commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by
default") the probing of TTY consoles could get delayed if they have
optional suppliers that are listed in DT, but those suppliers don't
probe by the time kernel boot finishes. The console devices will probe
eventually after driver_probe_timeout expires.

However, since consoles are often used for debugging kernel issues, it
does not make sense to delay their probe. So, set the newly added
probe_no_timeout flag for all serial drivers that at DT based. This way,
fw_devlink will know not to delay the probing of the consoles past
kernel boot.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")

[PATCH v1 2/2] serial: Set probe_no_timeout for all DT based drivers

[Saravana Kannan]

With commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by
default") the probing of TTY consoles could get delayed if they have
optional suppliers that are listed in DT, but those suppliers don't
probe by the time kernel boot finishes. The console devices will probe
eventually after driver_probe_timeout expires.

However, since consoles are often used for debugging kernel issues, it
does not make sense to delay their probe. So, set the newly added
probe_no_timeout flag for all serial drivers that at DT based. This way,
fw_devlink will know not to delay the probing of the consoles past
kernel boot.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")

[PATCH v1 2/2] serial: Set probe_no_timeout for all DT based drivers

[Saravana Kannan]

With commit 71066545b48e ("driver core: Set fw_devlink.strict=1 by
default") the probing of TTY consoles could get delayed if they have
optional suppliers that are listed in DT, but those suppliers don't
probe by the time kernel boot finishes. The console devices will probe
eventually after driver_probe_timeout expires.

However, since consoles are often used for debugging kernel issues, it
does not make sense to delay their probe. So, set the newly added
probe_no_timeout flag for all serial drivers that at DT based. This way,
fw_devlink will know not to delay the probing of the consoles past
kernel boot.

Fixes: 71066545b48e ("driver core: Set fw_devlink.strict=1 by default")
