Revision b4cd08aa1f53c831e67dc5c6bc9f9acff27abcba authored by Wolfram Sang on 16 December 2015, 19:05:18 UTC, committed by Wolfram Sang on 19 December 2015, 11:00:37 UTC
When we also are I2C slave, we need to disable runtime PM because the address detection mechanism needs to be active all the time. However, we can reenable runtime PM once the slave instance was unregistered. So, use pm_runtime_get_sync/put to achieve this, since it has proper refcounting. pm_runtime_allow/forbid is like a global knob controllable from userspace which is unsuitable here.

menuconfig WAN
bool "Wan interfaces support"
---help---
Wide Area Networks (WANs), such as X.25, Frame Relay and leased
lines, are used to interconnect Local Area Networks (LANs) over vast
distances with data transfer rates significantly higher than those
achievable with commonly used asynchronous modem connections.
Usually, a quite expensive external device called a `WAN router' is
needed to connect to a WAN. As an alternative, a relatively
inexpensive WAN interface card can allow your Linux box to directly
connect to a WAN.
If you have one of those cards and wish to use it under Linux,
say Y here and also to the WAN driver for your card.
If unsure, say N.

help
Driver for Comtrol Hostess SV-11 network card which
operates on low speed synchronous serial links at up to
256Kbps, supporting PPP and Cisco HDLC.

config COSA
tristate "COSA/SRP sync serial boards support"
depends on ISA && m && ISA_DMA_API && HDLC && VIRT_TO_BUS
---help---
Driver for COSA and SRP synchronous serial boards.
These boards allow to connect synchronous serial devices (for example
base-band modems, or any other device with the X.21, V.24, V.35 or
V.36 interface) to your Linux box. The cards can work as the
character device, synchronous PPP network device, or the Cisco HDLC
network device.
You will need user-space utilities COSA or SRP boards for downloading
the firmware to the cards and to set them up. Look at the
<http://www.fi.muni.cz/~kas/cosa/> for more information. You can also
read the comment at the top of the <file:drivers/net/wan/cosa.c> for
details about the cards and the driver itself.
The driver will be compiled as a module: the
module will be called cosa.

box directly to a T1 or E1 circuit.
- LMC 5200 board provides a HSSI interface capable of running up to
52 Mbits per second.

config FARSYNC
tristate "FarSync T-Series support"
depends on HDLC && PCI
---help---
Support for the FarSync T-Series X.21 (and V.35/V.24) cards by
FarSite Communications Ltd.
Synchronous communication is supported on all ports at speeds up to
8Mb/s (128K on V.24) using synchronous PPP, Cisco HDLC, raw HDLC,
Frame Relay or X.25/LAPB.
If you want the module to be automatically loaded when the interface
is referenced then you should add "alias hdlcX farsync" to a file
in /etc/modprobe.d/ for each interface, where X is 0, 1, 2, ..., or
simply use "alias hdlc* farsync" to indicate all of them.
To compile this driver as a module, choose M here: the

config DSCC4
tristate "Etinc PCISYNC serial board support"
depends on HDLC && PCI && m
help
Driver for Etinc PCISYNC boards based on the Infineon (ex. Siemens)
DSCC4 chipset.
This is supposed to work with the four port card. Take a look at
<http://www.cogenit.fr/dscc4/> for further information about the
driver.
To compile this driver as a module, choose M here: the
module will be called dscc4.
config DSCC4_PCISYNC
bool "Etinc PCISYNC features"
depends on DSCC4
help
Due to Etinc's design choice for its PCISYNC cards, some operations
are only allowed on specific ports of the DSCC4. This option is the
only way for the driver to know that it shouldn't return a success
code for these operations.
Please say Y if your card is an Etinc's PCISYNC.
config DSCC4_PCI_RST
bool "Hard reset support"
depends on DSCC4
help
Various DSCC4 bugs forbid any reliable software reset of the ASIC.
As a replacement, some vendors provide a way to assert the PCI #RST
pin of DSCC4 through the GPIO port of the card. If you choose Y,
the driver will make use of this feature before module removal
(i.e. rmmod). The feature is known to be available on Commtech's
cards. Contact your manufacturer for details.
Say Y if your card supports this feature.
config IXP4XX_HSS

config DLCI
tristate "Frame Relay DLCI support"
---help---
Support for the Frame Relay protocol.
Frame Relay is a fast low-cost way to connect to a remote Internet
access provider or to form a private wide area network. The one
physical line from your box to the local "switch" (i.e. the entry
point to the Frame Relay network, usually at the phone company) can
carry several logical point-to-point connections to other computers
connected to the Frame Relay network. For a general explanation of
the protocol, check out <http://www.mplsforum.org/>.
To use frame relay, you need supporting hardware (called FRAD) and
certain programs from the net-tools package as explained in
<file:Documentation/networking/framerelay.txt>.
To compile this driver as a module, choose M here: the
module will be called dlci.
config DLCI_MAX

help
Driver for the Sangoma S502A, S502E, and S508 Frame Relay Access
Devices.
These are multi-protocol cards, but only Frame Relay is supported
by the driver at this time. Please read

To compile this driver as a module, choose M here: the
module will be called sdla.
# X.25 network drivers
config LAPBETHER
tristate "LAPB over Ethernet driver"
depends on LAPB && X25
---help---
Driver for a pseudo device (typically called /dev/lapb0) which allows
you to open an LAPB point-to-point connection to some other computer
on your Ethernet network.
In order to do this, you need to say Y or M to the driver for your
Ethernet card as well as to "LAPB Data Link Driver".
To compile this driver as a module, choose M here: the
module will be called lapbether.
If unsure, say N.
config X25_ASY
tristate "X.25 async driver"
depends on LAPB && X25 && TTY
---help---

lines such as telephone lines equipped with ordinary modems.
Experts should note that this driver doesn't currently comply with
the asynchronous HDLS framing protocols in CCITT recommendation X.25.
To compile this driver as a module, choose M here: the
module will be called x25_asy.
If unsure, say N.
config SBNI
tristate "Granch SBNI12 Leased Line adapter support"
depends on X86
---help---

leased line modems.
You can find more information and last versions of drivers and
utilities at <http://www.granch.ru/>. If you have any question you
can send email to <sbni@granch.ru>.
To compile this driver as a module, choose M here: the
module will be called sbni.
If unsure, say N.
config SBNI_MULTILINE
bool "Multiple line feature support"
depends on SBNI
help
Schedule traffic for some parallel lines, via SBNI12 adapters.
If you have two computers connected with two parallel lines it's
possible to increase transfer rate nearly twice. You should have
a program named 'sbniconfig' to configure adapters.
If unsure, say N.
