Merge tag 'omap-cleanup-b-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into cleanup-makefile-sparse
smatch and string-wrapping cleanups for the OMAP subarch code.
These changes fix some of the more meaningful warnings that smatch
returns for the OMAP subarch code, and unwraps strings that are
wrapped at the 80-column boundary, to conform with the current
practice.
Basic build, boot, and PM logs are available here:

-Computone Intelliport II/Plus Multiport Serial Driver
------------------------------------------------------
-
-Release Notes For Linux Kernel 2.2 and higher.
-These notes are for the drivers which have already been integrated into the
-kernel and have been tested on Linux kernels 2.0, 2.2, 2.3, and 2.4.
-
-Version: 1.2.14
-Date: 11/01/2001
-Historical Author: Andrew Manison <amanison@america.net>
-Primary Author: Doug McNash
-
-This file assumes that you are using the Computone drivers which are
-integrated into the kernel sources. For updating the drivers or installing
-drivers into kernels which do not already have Computone drivers, please
-refer to the instructions in the README.computone file in the driver patch.
-
-
-1. INTRODUCTION
-
-This driver supports the entire family of Intelliport II/Plus controllers
-with the exception of the MicroChannel controllers. It does not support
-products previous to the Intelliport II.
-
-This driver was developed on the v2.0.x Linux tree and has been tested up
-to v2.4.14; it will probably not work with earlier v1.X kernels,.
-
-
-2. QUICK INSTALLATION
-
-Hardware - If you have an ISA card, find a free interrupt and io port.
- List those in use with `cat /proc/interrupts` and
- `cat /proc/ioports`. Set the card dip switches to a free
- address. You may need to configure your BIOS to reserve an
- irq for an ISA card. PCI and EISA parameters are set
- automagically. Insert card into computer with the power off
- before or after drivers installation.
-
- Note the hardware address from the Computone ISA cards installed into
- the system. These are required for editing ip2.c or editing
- /etc/modprobe.d/*.conf, or for specification on the modprobe
- command line.
-
- Note that the /etc/modules.conf should be used for older (pre-2.6)
- kernels.
-
-Software -
-
-Module installation:
-
-a) Determine free irq/address to use if any (configure BIOS if need be)
-b) Run "make config" or "make menuconfig" or "make xconfig"
- Select (m) module for CONFIG_COMPUTONE under character
- devices. CONFIG_PCI and CONFIG_MODULES also may need to be set.
-c) Set address on ISA cards then:
- edit /usr/src/linux/drivers/char/ip2.c if needed
- or
- edit config file in /etc/modprobe.d/ if needed (module).
- or both to match this setting.
-d) Run "make modules"
-e) Run "make modules_install"
-f) Run "/sbin/depmod -a"
-g) install driver using `modprobe ip2 <options>` (options listed below)
-h) run ip2mkdev (either the script below or the binary version)
-
-
-Kernel installation:
-
-a) Determine free irq/address to use if any (configure BIOS if need be)
-b) Run "make config" or "make menuconfig" or "make xconfig"
- Select (y) kernel for CONFIG_COMPUTONE under character
- devices. CONFIG_PCI may need to be set if you have PCI bus.
-c) Set address on ISA cards then:
- edit /usr/src/linux/drivers/char/ip2.c
- (Optional - may be specified on kernel command line now)
-d) Run "make zImage" or whatever target you prefer.
-e) mv /usr/src/linux/arch/x86/boot/zImage to /boot.
-f) Add new config for this kernel into /etc/lilo.conf, run "lilo"
- or copy to a floppy disk and boot from that floppy disk.
-g) Reboot using this kernel
-h) run ip2mkdev (either the script below or the binary version)
-
-Kernel command line options:
-
-When compiling the driver into the kernel, io and irq may be
-compiled into the driver by editing ip2.c and setting the values for
-io and irq in the appropriate array. An alternative is to specify
-a command line parameter to the kernel at boot up.
-
- ip2=io0,irq0,io1,irq1,io2,irq2,io3,irq3
-
-Note that this order is very different from the specifications for the
-modload parameters which have separate IRQ and IO specifiers.
-
-The io port also selects PCI (1) and EISA (2) boards.
-
- io=0 No board
- io=1 PCI board
- io=2 EISA board
- else ISA board io address
-
-You only need to specify the boards which are present.
-
- Examples:
-
- 2 PCI boards:
-
- ip2=1,0,1,0
-
- 1 ISA board at 0x310 irq 5:
-
- ip2=0x310,5
-
-This can be added to and "append" option in lilo.conf similar to this:
-
- append="ip2=1,0,1,0"
-
-
-3. INSTALLATION
-
-Previously, the driver sources were packaged with a set of patch files
-to update the character drivers' makefile and configuration file, and other
-kernel source files. A build script (ip2build) was included which applies
-the patches if needed, and build any utilities needed.
-What you receive may be a single patch file in conventional kernel
-patch format build script. That form can also be applied by
-running patch -p1 < ThePatchFile. Otherwise run ip2build.
-
-The driver can be installed as a module (recommended) or built into the
-kernel. This is selected as for other drivers through the `make config`
-command from the root of the Linux source tree. If the driver is built
-into the kernel you will need to edit the file ip2.c to match the boards
-you are installing. See that file for instructions. If the driver is
-installed as a module the configuration can also be specified on the
-modprobe command line as follows:
-
- modprobe ip2 irq=irq1,irq2,irq3,irq4 io=addr1,addr2,addr3,addr4
-
-where irqnum is one of the valid Intelliport II interrupts (3,4,5,7,10,11,
-12,15) and addr1-4 are the base addresses for up to four controllers. If
-the irqs are not specified the driver uses the default in ip2.c (which
-selects polled mode). If no base addresses are specified the defaults in
-ip2.c are used. If you are autoloading the driver module with kerneld or
-kmod the base addresses and interrupt number must also be set in ip2.c
-and recompile or just insert and options line in /etc/modprobe.d/*.conf or both.
-The options line is equivalent to the command line and takes precedence over
-what is in ip2.c.
-
-config sample to put /etc/modprobe.d/*.conf:
- options ip2 io=1,0x328 irq=1,10
- alias char-major-71 ip2
- alias char-major-72 ip2
- alias char-major-73 ip2
-
-The equivalent in ip2.c:
-
-static int io[IP2_MAX_BOARDS]= { 1, 0x328, 0, 0 };
-static int irq[IP2_MAX_BOARDS] = { 1, 10, -1, -1 };
-
-The equivalent for the kernel command line (in lilo.conf):
-
- append="ip2=1,1,0x328,10"
-
-
-Note: Both io and irq should be updated to reflect YOUR system. An "io"
- address of 1 or 2 indicates a PCI or EISA card in the board table.
- The PCI or EISA irq will be assigned automatically.
-
-Specifying an invalid or in-use irq will default the driver into
-running in polled mode for that card. If all irq entries are 0 then
-all cards will operate in polled mode.
-
-If you select the driver as part of the kernel run :
-
- make zlilo (or whatever you do to create a bootable kernel)
-
-If you selected a module run :
-
- make modules && make modules_install
-
-The utility ip2mkdev (see 5 and 7 below) creates all the device nodes
-required by the driver. For a device to be created it must be configured
-in the driver and the board must be installed. Only devices corresponding
-to real IntelliPort II ports are created. With multiple boards and expansion
-boxes this will leave gaps in the sequence of device names. ip2mkdev uses
-Linux tty naming conventions: ttyF0 - ttyF255 for normal devices, and
-cuf0 - cuf255 for callout devices.
-
-
-4. USING THE DRIVERS
-
-As noted above, the driver implements the ports in accordance with Linux
-conventions, and the devices should be interchangeable with the standard
-serial devices. (This is a key point for problem reporting: please make
-sure that what you are trying do works on the ttySx/cuax ports first; then
-tell us what went wrong with the ip2 ports!)
-
-Higher speeds can be obtained using the setserial utility which remaps
-38,400 bps (extb) to 57,600 bps, 115,200 bps, or a custom speed.
-Intelliport II installations using the PowerPort expansion module can
-use the custom speed setting to select the highest speeds: 153,600 bps,
-230,400 bps, 307,200 bps, 460,800bps and 921,600 bps. The base for
-custom baud rate configuration is fixed at 921,600 for cards/expansion
-modules with ST654's and 115200 for those with Cirrus CD1400's. This
-corresponds to the maximum bit rates those chips are capable.
-For example if the baud base is 921600 and the baud divisor is 18 then
-the custom rate is 921600/18 = 51200 bps. See the setserial man page for
-complete details. Of course if stty accepts the higher rates now you can
-use that as well as the standard ioctls().
-
-
-5. ip2mkdev and assorted utilities...
-
-Several utilities, including the source for a binary ip2mkdev utility are
-available under .../drivers/char/ip2. These can be build by changing to
-that directory and typing "make" after the kernel has be built. If you do
-not wish to compile the binary utilities, the shell script below can be
-cut out and run as "ip2mkdev" to create the necessary device files. To
-use the ip2mkdev script, you must have procfs enabled and the proc file
-system mounted on /proc.
-
-
-6. NOTES
-
-This is a release version of the driver, but it is impossible to test it
-in all configurations of Linux. If there is any anomalous behaviour that
-does not match the standard serial port's behaviour please let us know.
-
-
-7. ip2mkdev shell script
-
-Previously, this script was simply attached here. It is now attached as a
-shar archive to make it easier to extract the script from the documentation.
-To create the ip2mkdev shell script change to a convenient directory (/tmp
-works just fine) and run the following command:
-
- unshar Documentation/serial/computone.txt
- (This file)
-
-You should now have a file ip2mkdev in your current working directory with
-permissions set to execute. Running that script with then create the
-necessary devices for the Computone boards, interfaces, and ports which
-are present on you system at the time it is run.
-
