Add ACPI support for serial attached devices.
Currently, serial devices are not set as enumerated during
ACPI scan for SPI or i2c buses (but not for UART). This
should also be done for UART serial devices. I renamed
*spi_i2c_slave* to *serial_bus_slave* to reflect this.
This needs Johan Hovold's "serdev: fix registration of
second slave" patch.
In theory this series could go in through the acpi-tree
without my fix. It would only affect an error case where an
unlikely failure to register an ACPI serdev device, would
prevent the tty-class device from being registered instead of
the controller. That is, something we can live with until this
all converges in 4.15-rc1 if needed.
That said, I think we should consider taking all serdev
changes, and therefore also the ACPI patch, through the tty
tree instead in order to avoid merge conflicts. Rafael?
OK
Please feel free to add
Acked-by: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
to the ACPI core change.
And I will assume that this series will go in via the tty tree.
you have to take these two patches now via the TTY tree now. In
case you already marked them as someone else problem ;)
Is there any problem I missed with those patches?
Do I have to re-send them?
No, they are in my queue, still catching up...
I just realised that we cannot merge this series (the second acpi patch)
until the hci_intel driver gains serdev support or otherwise PM will
break for those devices.
Specifically, the hci_intel driver uses similar hacks as the hci_bcm
driver does for PM, so we need something like Hans's hci_bcm series also
for hci_intel before we can do the switch.
Hmm, I've never actually seen any hardware use an intel BT HCI connected
to a serdev, but I guess people did not write that code for fun, so those
do exist ?

Hans
