S3C24XX USB Host support
|
||||
========================
|
||||
|
||||
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
This document details the S3C2410/S3C2440 in-built OHCI USB host support.
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
Enable at least the following kernel options:
|
||||
|
||||
menuconfig:
|
||||
|
||||
Device Drivers --->
|
||||
USB support --->
|
||||
<*> Support for Host-side USB
|
||||
<*> OHCI HCD support
|
||||
|
||||
|
||||
.config:
|
||||
CONFIG_USB
|
||||
CONFIG_USB_OHCI_HCD
|
||||
|
||||
|
||||
Once these options are configured, the standard set of USB device
|
||||
drivers can be configured and used.
|
||||
|
||||
|
||||
Board Support
|
||||
-------------
|
||||
|
||||
The driver attaches to a platform device, which will need to be
|
||||
added by the board specific support file in linux/arch/arm/mach-s3c2410,
|
||||
such as mach-bast.c or mach-smdk2410.c
|
||||
|
||||
The platform device's platform_data field is only needed if the
|
||||
board implements extra power control or over-current monitoring.
|
||||
|
||||
The OHCI driver does not ensure the state of the S3C2410's MISCCTRL
|
||||
register, so if both ports are to be used for the host, then it is
|
||||
the board support file's responsibility to ensure that the second
|
||||
port is configured to be connected to the OHCI core.
|
||||
|
||||
|
||||
Platform Data
|
||||
-------------
|
||||
|
||||
See linux/include/asm-arm/arch-s3c2410/usb-control.h for the
|
||||
descriptions of the platform device data. An implementation
|
||||
can be found in linux/arch/arm/mach-s3c2410/usb-simtec.c .
|
||||
|
||||
The `struct s3c2410_hcd_info` contains a pair of functions
|
||||
that get called to enable over-current detection, and to
|
||||
control the port power status.
|
||||
|
||||
The ports are numbered 0 and 1.
|
||||
|
||||
power_control:
|
||||
|
||||
Called to enable or disable the power on the port.
|
||||
|
||||
enable_oc:
|
||||
|
||||
Called to enable or disable the over-current monitoring.
|
||||
This should claim or release the resources being used to
|
||||
check the power condition on the port, such as an IRQ.
|
||||
|
||||
report_oc:
|
||||
|
||||
The OHCI driver fills this field in for the over-current code
|
||||
to call when there is a change to the over-current state on
|
||||
an port. The ports argument is a bitmask of 1 bit per port,
|
||||
with bit X being 1 for an over-current on port X.
|
||||
|
||||
The function s3c2410_usb_report_oc() has been provided to
|
||||
ensure this is called correctly.
|
||||
|
||||
port[x]:
|
||||
|
||||
This is struct describes each port, 0 or 1. The platform driver
|
||||
should set the flags field of each port to S3C_HCDFLG_USED if
|
||||
the port is enabled.

||||
