Maximum brightness for <backlight>.

Contact: Matthew Garrett <mjg@redhat.com>
Description:
The type of interface controlled by <backlight>.
"firmware": The driver uses a standard firmware interface
"platform": The driver uses a platform-specific interface
"raw": The driver controls hardware registers directly
In the general case, when multiple backlight
interfaces are available for a single device, firmware
control should be preferred to platform control should
be preferred to raw control. Using a firmware
interface reduces the probability of confusion with
the hardware and the OS independently updating the
backlight state. Platform interfaces are mostly a
holdover from pre-standardisation of firmware
interfaces.

RISC OS file type suffix
------------------------
RISC OS file types are stored in bits 19..8 of the file load address.
To enable non-RISC OS systems to be used to store files without losing
file type information, a file naming convention was devised (initially
for use with NFS) such that a hexadecimal suffix of the form ,xyz
denoted the file type: e.g. BasicFile,ffb is a BASIC (0xffb) file. This
naming convention is now also used by RISC OS emulators such as RPCEmu.
Mounting an ADFS disc with option ftsuffix=1 will cause appropriate file
type suffixes to be appended to file names read from a directory. If the
ftsuffix option is zero or omitted, no file type suffixes will be added.

Kernel driver i2c-diolan-u2c
Supported adapters:
* Diolan U2C-12 I2C-USB adapter
Documentation:
http://www.diolan.com/i2c/u2c12.html
Author: Guenter Roeck <guenter.roeck@ericsson.com>
Description
-----------
This is the driver for the Diolan U2C-12 USB-I2C adapter.
The Diolan U2C-12 I2C-USB Adapter provides a low cost solution to connect
a computer to I2C slave devices using a USB interface. It also supports
connectivity to SPI devices.
This driver only supports the I2C interface of U2C-12. The driver does not use
interrupts.

Spear PCIe Gadget Driver:
Author

driver/misc/spear13xx_pcie_gadget.c
Supported Chip:
===================

Device Drivers
Misc devices
PCIe gadget support for SPEAr13XX platform
purpose
===========
This driver has several nodes which can be read/written by configfs interface.
Its main purpose is to configure selected dual mode PCIe controller as device
and then program its various registers to configure it as a particular device
type. This driver can be used to show spear's PCIe device capability.
Description of different nodes:
=================================
read behavior of nodes:
------------------------------
link :gives ltssm status.
int_type :type of supported interrupt
no_of_msi :zero if MSI is not enabled by host. A positive value is the
number of MSI vector granted.
vendor_id :returns programmed vendor id (hex)
device_id :returns programmed device id(hex)
bar0_size: :returns size of bar0 in hex.
bar0_address :returns address of bar0 mapped area in hex.
bar0_rw_offset :returns offset of bar0 for which bar0_data will return value.
bar0_data :returns data at bar0_rw_offset.
write behavior of nodes:
------------------------------
link :write UP to enable ltsmm DOWN to disable
int_type :write interrupt type to be configured and (int_type could be
INTA, MSI or NO_INT). Select MSI only when you have programmed
no_of_msi node.
no_of_msi :number of MSI vector needed.
inta :write 1 to assert INTA and 0 to de-assert.
send_msi :write MSI vector to be sent.
vendor_id :write vendor id(hex) to be programmed.
device_id :write device id(hex) to be programmed.
bar0_size :write size of bar0 in hex. default bar0 size is 1000 (hex)
bytes.
bar0_address :write address of bar0 mapped area in hex. (default mapping of
bar0 is SYSRAM1(E0800000). Always program bar size before bar
address. Kernel might modify bar size and address for alignment, so
read back bar size and address after writing to cross check.
bar0_rw_offset :write offset of bar0 for which bar0_data will write value.
bar0_data :write data to be written at bar0_rw_offset.
Node programming example
===========================
Program all PCIe registers in such a way that when this device is connected
to the PCIe host, then host sees this device as 1MB RAM.
#mount -t configfs none /Config
For nth PCIe Device Controller
# cd /config/pcie_gadget.n/
Now you have all the nodes in this directory.
program vendor id as 0x104a
# echo 104A >> vendor_id
program device id as 0xCD80
# echo CD80 >> device_id
program BAR0 size as 1MB
# echo 100000 >> bar0_size
check for programmed bar0 size
# cat bar0_size
Program BAR0 Address as DDR (0x2100000). This is the physical address of
memory, which is to be made visible to PCIe host. Similarly any other peripheral
can also be made visible to PCIe host. E.g., if you program base address of UART
as BAR0 address then when this device will be connected to a host, it will be
visible as UART.
# echo 2100000 >> bar0_address
program interrupt type : INTA
# echo INTA >> int_type
go for link up now.
# echo UP >> link
It will have to be insured that, once link up is done on gadget, then only host
is initialized and start to search PCIe devices on its port.
/*wait till link is up*/
# cat link
wait till it returns UP.
To assert INTA
# echo 1 >> inta
To de-assert INTA
# echo 0 >> inta
if MSI is to be used as interrupt, program no of msi vector needed (say4)
# echo 4 >> no_of_msi
select MSI as interrupt type
# echo MSI >> int_type
go for link up now
# echo UP >> link
wait till link is up
# cat link
An application can repetitively read this node till link is found UP. It can
sleep between two read.
wait till msi is enabled
# cat no_of_msi
Should return 4 (number of requested MSI vector)
to send msi vector 2
# echo 2 >> send_msi
#cd -
