Merge remote-tracking branch 'origin/front' into front

Auth/box previously switched to /, rather than
preserving the cwd. This would break relative
paths to items that would get pulled into the
namespace.

This change removes the '-.' flag, and causes
auth/box to keep the current working directory,
making it more usable for scripting.

+.SH SYNOPSIS
+.nf
+.B bind -a #J /dev
+.PP
+.nf
+.BI /dev/ bus /i2c. n .ctl
+.BI /dev/ bus /i2c. n .data
+.SH DESCRIPTION
+The I²C (Inter-Integrated Circuit) bus is a serial bus standard
+invented by Philips.
+It is used to connect chips over short-distances like on a motherboard
+or between boards.
+The bus requires only a single data signal 
+.IR SDA ,
+a clock signal
+.I SDC
+and ground.
+Devices on the bus have 7-bit or 10-bit addresses, which is
+determined by the device (see the datasheet).
+Every device monitors the bus and waits for the master to initiate
+a transaction.
+Each transaction starts with the master sending the target device address
+with a direction bit and the device acknowledges each byte
+received if its address matched.
+Depending on the device, more bytes must be transmitted after the
+.IR device-address .
+For example, encoding a register number at a memory offset.
+We refer to these bytes as the
+.IR sub-address .
+After the address phase, the data phase begins where
+zero or more data bytes are either transmitted or received
+depending on the transaction direction.
+.PP
+This driver supports multiple buses (controllers) to be registered
+by platform specific code in the kernel.
+Each bus is represented as a directory with a platform specific name.
+.PP
+Because all received bytes are acknowledged by target devices,
+it is possible for the master to enumerate all existing addresses
+on a bus, which is done when accessing the
+.I bus
+directory.
+.PP
+Platform specific code can also register individual devices,
+supplying a meaningful device configuration.
+It can also be necessary to manually register devices if
+the device has been disabled by an enable signal or
+otherwise inhibited during enumeration.
+.PP
+Each device appears as a control (
+.BI i2c. n .ctl
+)
+and a data file (
+.BI i2c. n .data
+) in the
+.I bus
+directory
+where
+.I n
+is the device-address in hexadecimal.
+.PP
+The data file is used to initiate transactions to the device.
+The initial
+.I sub-address
+bytes sent are derived from the file position according to the device
+configuration, and the length of the data phase is controlled by
+the requested read or write size.
+The requested size might be truncated by the driver if
+the request exceeds the logical file-size.
+.PP
+The control-file provides access to the device configuration.
+When read,
+it reproduces this configuration in text form.
+The following text lines are accepted when written to the control-file:
+.TF "subaddress n"
+.TP
+.BI "subaddress " n
+Sets the length
+.IR n ,
+in bytes, of the sub-address for the device
+that is derived from the file-position of the data-file.
+This can be set to zero if no sub-address bytes should
+be generated by the driver.
+By default, the sub-address length is 1.
+.TP
+.BI "size " n
+Changes the logical size of the data-file to
+.IR n .
+Making sure the file-position is not exceeding this size.
+.SH SOURCE
+.B /sys/src/9/port/devi2c.c
+.SH HISTORY
+The file-interface has been inspired by infernos devi2c,
+but with the addition of supporting multiple buses
+and device enumeration.
