+
+4. Userspace Programming
+------------------------
+
+The cfag12864bfb describes a framebuffer device (/dev/fbX).
+
+It has a size of 1024 bytes = 1 Kbyte.
+Each bit represents one pixel. If the bit is high, the pixel will
+turn on. If the pixel is low, the pixel will turn off.
+
+You can use the framebuffer as a file: fopen, fwrite, fclose...
+Although the LCD won't get updated until the next refresh time arrives.
+
+Also, you can mmap the framebuffer: open & mmap, munmap & close...
+which is the best option for most uses.
+
+Check samples/auxdisplay/cfag12864b-example.c
+for a real working userspace complete program with usage examples.

-Brutus
-======
-
-Brutus is an evaluation platform for the SA1100 manufactured by Intel.
-For more details, see:
-
-http://developer.intel.com
-
-To compile for Brutus, you must issue the following commands::
-
-	make brutus_config
-	make config
-	[accept all the defaults]
-	make zImage
-
-The resulting kernel will end up in linux/arch/arm/boot/zImage.  This file
-must be loaded at 0xc0008000 in Brutus's memory and execution started at
-0xc0008000 as well with the value of registers r0 = 0 and r1 = 16 upon
-entry.
-
-But prior to execute the kernel, a ramdisk image must also be loaded in
-memory.  Use memory address 0xd8000000 for this.  Note that the file
-containing the (compressed) ramdisk image must not exceed 4 MB.
-
-Typically, you'll need angelboot to load the kernel.
-The following angelboot.opt file should be used::
-
-	base 0xc0008000
-	entry 0xc0008000
-	r0 0x00000000
-	r1 0x00000010
-	device /dev/ttyS0
-	options "9600 8N1"
-	baud 115200
-	otherfile ramdisk_img.gz
-	otherbase 0xd8000000
-
-Then load the kernel and ramdisk with::
-
-	angelboot -f angelboot.opt zImage
-
-The first Brutus serial port (assumed to be linked to /dev/ttyS0 on your
-host PC) is used by angel to load the kernel and ramdisk image. The serial
-console is provided through the second Brutus serial port. To access it,
-you may use minicom configured with /dev/ttyS1, 9600 baud, 8N1, no flow
-control.
-
-Currently supported
-===================
-
-	- RS232 serial ports
-	- audio output
-	- LCD screen
-	- keyboard
-
-The actual Brutus support may not be complete without extra patches.
-If such patches exist, they should be found from
-ftp.netwinder.org/users/n/nico.
-
-A full PCMCIA support is still missing, although it's possible to hack
-some drivers in order to drive already inserted cards at boot time with
-little modifications.

-Notes
-=====
-
- The flash on board is divided into 3 partitions.  mtd0 is where
-  the ADS boot ROM and zImage is stored.  It's been marked as
-  read-only to keep you from blasting over the bootloader. :)  mtd1 is
-  for the ramdisk.gz image.  mtd2 is user flash space and can be
-  utilized for either JFFS or if you're feeling crazy, running ext2
-  on top of it. If you're not using the ADS bootloader, you're
-  welcome to blast over the mtd1 partition also.
-
- 16bpp mode requires a different cable than what ships with the board.
-  Contact ADS or look through the manual to wire your own. Currently,
-  if you compile with 16bit mode support and switch into a lower bpp
-  mode, the timing is off so the image is corrupted.  This will be
-  fixed soon.

-Itsy
-====
-
-Itsy is a research project done by the Western Research Lab, and Systems
-Research Center in Palo Alto, CA. The Itsy project is one of several
-research projects at Compaq that are related to pocket computing.
-
-For more information, see:
-
-	http://www.hpl.hp.com/downloads/crl/itsy/
-
-Notes on initial 2.4 Itsy support (8/27/2000) :
-
-The port was done on an Itsy version 1.5 machine with a daughtercard with
-64 Meg of DRAM and 32 Meg of Flash. The initial work includes support for
-serial console (to see what you're doing).  No other devices have been
-enabled.
-
-To build, do a "make menuconfig" (or xmenuconfig) and select Itsy support.
-Disable Flash and LCD support. and then do a make zImage.
-Finally, you will need to cd to arch/arm/boot/tools and execute a make there
-to build the params-itsy program used to boot the kernel.
-
-In order to install the port of 2.4 to the itsy, You will need to set the
-configuration parameters in the monitor as follows::
-
-	Arg 1:0x08340000, Arg2: 0xC0000000, Arg3:18 (0x12), Arg4:0
-
-Make sure the start-routine address is set to 0x00060000.
-
-Next, flash the params-itsy program to 0x00060000 ("p 1 0x00060000" in the
-flash menu)  Flash the kernel in arch/arm/boot/zImage into 0x08340000
-("p 1 0x00340000").  Finally flash an initial ramdisk into 0xC8000000
-("p 2 0x0")  We used ramdisk-2-30.gz from the 0.11 version directory on
-handhelds.org.
-
-The serial connection we established was at:
-
-8-bit data, no parity, 1 stop bit(s), 115200.00 b/s. in the monitor, in the
-params-itsy program, and in the kernel itself.  This can be changed, but
-not easily. The monitor parameters are easily changed, the params program
-setup is assembly outl's, and the kernel is a configuration item specific to
-the itsy. (i.e. grep for CONFIG_SA1100_ITSY and you'll find where it is.)
-
-
-This should get you a properly booting 2.4 kernel on the itsy.

-4. USERSPACE PROGRAMMING
------------------------
-
-The cfag12864bfb describes a framebuffer device (/dev/fbX).
-
-It has a size of 1024 bytes = 1 Kbyte.
-Each bit represents one pixel. If the bit is high, the pixel will
-turn on. If the pixel is low, the pixel will turn off.
-
-You can use the framebuffer as a file: fopen, fwrite, fclose...
-Although the LCD won't get updated until the next refresh time arrives.
-
-Also, you can mmap the framebuffer: open & mmap, munmap & close...
-which is the best option for most uses.
-
-Check samples/auxdisplay/cfag12864b-example.c
-for a real working userspace complete program with usage examples.

+Writing DeviceTree Bindings in json-schema
+==========================================

 Devicetree bindings are written using json-schema vocabulary. Schema files are
 written in a JSON compatible subset of YAML. YAML is used instead of JSON as it
 considered more human readable and has some advantages such as allowing
 comments (Prefixed with '#').

-## Schema Contents
+Schema Contents
+---------------

 Each schema doc is a structured json-schema which is defined by a set of
 top-level properties. Generally, there is one binding defined per file. The
 top-level json-schema properties used are:

- __$id__ - A json-schema unique identifier string. The string must be a valid
-URI typically containing the binding's filename and path. For DT schema, it must
-begin with "http://devicetree.org/schemas/". The URL is used in constructing
-references to other files specified in schema "$ref" properties. A $ref values
-with a leading '/' will have the hostname prepended. A $ref value a relative
-path or filename only will be prepended with the hostname and path components
-of the current schema file's '$id' value. A URL is used even for local files,
-but there may not actually be files present at those locations.
-
- __$schema__ - Indicates the meta-schema the schema file adheres to.
-
- __title__ - A one line description on the contents of the binding schema.
-
- __maintainers__ - A DT specific property. Contains a list of email address(es)
-for maintainers of this binding.
-
- __description__ - Optional. A multi-line text block containing any detailed
-information about this binding. It should contain things such as what the block
-or device does, standards the device conforms to, and links to datasheets for
-more information.
-
- __select__ - Optional. A json-schema used to match nodes for applying the
-schema. By default without 'select', nodes are matched against their possible
-compatible string values or node name. Most bindings should not need select.
-
- __allOf__ - Optional. A list of other schemas to include. This is used to
-include other schemas the binding conforms to. This may be schemas for a
-particular class of devices such as I2C or SPI controllers.
-
- __properties__ - A set of sub-schema defining all the DT properties for the
-binding. The exact schema syntax depends on whether properties are known,
-common properties (e.g. 'interrupts') or are binding/vendor specific properties.
-
-  A property can also define a child DT node with child properties defined
