Hi Johan, >> The current Kconfig for serdev is not compatible when adding ACPI support as it does not work when built as a module as it requires config SERIAL_DEV_CTRL_TTYPORT to be set. This patch makes serdev compiled into the kernel if selected so that config SERIAL_DEV_CTRL_TTYPORT can be correctly set if requiring ACPI support. >> --- >> drivers/tty/serdev/Kconfig | 5 +++-- >> 1 file changed, 3 insertions(+), 2 deletions(-) >> >> diff --git a/drivers/tty/serdev/Kconfig b/drivers/tty/serdev/Kconfig >> index cdc6b820cf93..a9fb09a9c105 100644 >> --- a/drivers/tty/serdev/Kconfig >> +++ b/drivers/tty/serdev/Kconfig >> @@ -2,7 +2,8 @@ >> # Serial bus device driver configuration >> # >> menuconfig SERIAL_DEV_BUS >> - tristate "Serial device bus" >> + bool "Serial device bus" >> + default y > > I understand why you want this (to prevent hci_bcm from breaking), but we > should generally not have new entries default to y. > >> help >> Core support for devices connected via a serial port. >> >> @@ -11,6 +12,6 @@ if SERIAL_DEV_BUS >> config SERIAL_DEV_CTRL_TTYPORT >> bool "Serial device TTY port controller" >> depends on TTY >> - depends on SERIAL_DEV_BUS != m >> + default y > > Same here. > > It may be better to have BT_HCIUART_BCM depend on (or select?) > SERIAL_DEV_CTRL_TTYPORT instead. if we move SERIAL_DEV_BUS to bool, then I would just have it be selected by BT_HCIUART_BCM. Frankly the SERIAL_DEV_BUS option is pretty hard to find in the kernel config. And if we depend on TTY, but then select SERIAL_DEV_BUS, I think that is a good compromise.
