+ Enable support for Character LCDs using a HD44780 controller.
+ The LCD is accessible through the /dev/lcd char device (10, 156).
+ This code can either be compiled as a module, or linked into the

+ ---help---
+ If you have a LCD controlled by one or more KS0108
+ controllers, say Y. You will need also another more specific
+ driver for your LCD.
+
+ Depends on Parallel Port support. If you say Y at
+ parport, you will be able to compile this as a module (M)
+ and built-in as well (Y).
+
+ To compile this as a module, choose M here:
+ the module will be called ks0108.

+ ---help---
+ The address of the parallel port where the LCD is connected.
+
+ The first standard parallel port address is 0x378.
+ The second standard parallel port address is 0x278.
+ The third standard parallel port address is 0x3BC.
+
+ You can specify a different address if you need.
+
+ If you don't know what I'm talking about, load the parport module,
+ and execute "dmesg" or "cat /proc/ioports". You can see there how
+ many parallel ports are present and which address each one has.
+
+ Usually you only need to use 0x378.
+
+ If you compile this as a module, you can still override this
+ using the module parameters.
+
+config KS0108_DELAY
+ int "Delay between each control writing (microseconds)"

+ to the parallel port.
+
+ If your LCD seems to miss random writings, increment this.
+
+ If you don't know what I'm talking about, ignore it.

+ If you compile this as a module, you can still override this
+ value using the module parameters.

+ check Documentation/auxdisplay/cfag12864b
+
+ Depends on the x86 arch and the framebuffer support.
+
+ The LCD framebuffer driver can be attached to a console.
+ It will work fine. However, you can't attach it to the fbdev driver
+ of the xorg server.

+ depends on CFAG12864B
+ default "20"
+ ---help---
+ Refresh rate of the LCD.
+
+ As the LCD is not memory mapped, the driver has to make the work by
+ software. This means you should be careful setting this value higher.
+ If your CPUs are really slow or you feel the system is slowed down,
+ decrease the value.
+
+ Be careful modifying this value to a very high value:
+ You can freeze the computer, or the LCD maybe can't draw as fast as you
+ are requesting.
+
+ If you don't know what I'm talking about, ignore it.
+
+ If you compile this as a module, you can still override this
+ value using the module parameters.

+ depends on PLAT_VERSATILE
+ help
+ This is a driver for the character LCD found on the ARM Ltd.
+ Versatile and RealView Platform Baseboards. It doesn't do
+ very much more than display the text "ARM Linux" on the first
+ line and the Linux version on the second line, but that's
+ still useful.

+ depends on PARPORT
+ select CHARLCD
+ ---help---
+ Say Y here if you have an HD44780 or KS-0074 LCD connected to your
+ parallel port. This driver also features 4 and 6-key keypads. The LCD
+ is accessible through the /dev/lcd char device (10, 156), and the
+ keypad through /dev/keypad (10, 185). This code can either be
+ compiled as a module, or linked into the kernel and started at boot.

+if PANEL
+
+config PANEL_PARPORT
+ int "Default parallel port number (0=LPT1)"
+ range 0 255
+ default "0"
+ ---help---
+ This is the index of the parallel port the panel is connected to. One
+ driver instance only supports one parallel port, so if your keypad
+ and LCD are connected to two separate ports, you have to start two
+ modules with different arguments. Numbering starts with '0' for LPT1,
+ and so on.
+
+config PANEL_PROFILE
+ int "Default panel profile (0-5, 0=custom)"
+ range 0 5
+ default "5"
+ ---help---
+ To ease configuration, the driver supports different configuration
+ profiles for past and recent wirings. These profiles can also be
+ used to define an approximative configuration, completed by a few
+ other options. Here are the profiles :
+
+ 0 = custom (see further)
+ 1 = 2x16 parallel LCD, old keypad
+ 2 = 2x16 serial LCD (KS-0074), new keypad
+ 3 = 2x16 parallel LCD (Hantronix), no keypad
+ 4 = 2x16 parallel LCD (Nexcom NSA1045) with Nexcom's keypad
+ 5 = 2x40 parallel LCD (old one), with old keypad
+
+ Custom configurations allow you to define how your display is
+ wired to the parallel port, and how it works. This is only intended
+ for experts.
+
+config PANEL_KEYPAD
+ depends on PANEL_PROFILE="0"
+ int "Keypad type (0=none, 1=old 6 keys, 2=new 6 keys, 3=Nexcom 4 keys)"
+ range 0 3
+ default 0
+ ---help---
+ This enables and configures a keypad connected to the parallel port.
+ The keys will be read from character device 10,185. Valid values are :
+
+ 0 : do not enable this driver
+ 1 : old 6 keys keypad
+ 2 : new 6 keys keypad, as used on the server at www.ant-computing.com
+ 3 : Nexcom NSA1045's 4 keys keypad
+
+ New profiles can be described in the driver source. The driver also
+ supports simultaneous keys pressed when the keypad supports them.
+
+config PANEL_LCD

+ int "LCD type (0=none, 1=custom, 2=old //, 3=ks0074, 4=hantronix, 5=Nexcom)"
+ range 0 5
+ default 0
+ ---help---
+ This enables and configures an LCD connected to the parallel port.
+ The driver includes an interpreter for escape codes starting with
+ '\e[L' which are specific to the LCD, and a few ANSI codes. The
+ driver will be registered as character device 10,156, usually
+ under the name '/dev/lcd'. There are a total of 6 supported types :
+
+ 0 : do not enable the driver
+ 1 : custom configuration and wiring (see further)
+ 2 : 2x16 & 2x40 parallel LCD (old wiring)
+ 3 : 2x16 serial LCD (KS-0074 based)
+ 4 : 2x16 parallel LCD (Hantronix wiring)
+ 5 : 2x16 parallel LCD (Nexcom wiring)
+
+ When type '1' is specified, other options will appear to configure
+ more precise aspects (wiring, dimensions, protocol, ...). Please note
+ that those values changed from the 2.4 driver for better consistency.
+
+config PANEL_LCD_HEIGHT
+ depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+ int "Number of lines on the LCD (1-2)"
+ range 1 2
+ default 2
+ ---help---
+ This is the number of visible character lines on the LCD in custom profile.
+ It can either be 1 or 2.
+
+config PANEL_LCD_WIDTH
+ depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+ int "Number of characters per line on the LCD (1-40)"
+ range 1 40
+ default 40
+ ---help---
+ This is the number of characters per line on the LCD in custom profile.
+ Common values are 16,20,24,40.
+
+config PANEL_LCD_BWIDTH
+ depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+ int "Internal LCD line width (1-40, 40 by default)"
+ range 1 40
+ default 40
+ ---help---
+ Most LCDs use a standard controller which supports hardware lines of 40
+ characters, although sometimes only 16, 20 or 24 of them are really wired
+ to the terminal. This results in some non-visible but addressable characters,
+ and is the case for most parallel LCDs. Other LCDs, and some serial ones,
+ however, use the same line width internally as what is visible. The KS0074
+ for example, uses 16 characters per line for 16 visible characters per line.
+
+ This option lets you configure the value used by your LCD in 'custom' profile.
+ If you don't know, put '40' here.
+
+config PANEL_LCD_HWIDTH
+ depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+ int "Hardware LCD line width (1-64, 64 by default)"
+ range 1 64
+ default 64
+ ---help---
+ Most LCDs use a single address bit to differentiate line 0 and line 1. Since
+ some of them need to be able to address 40 chars with the lower bits, they
+ often use the immediately superior power of 2, which is 64, to address the
+ next line.
+
+ If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and
+ 64 here for a 2x40.
+
+config PANEL_LCD_CHARSET
+ depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+ int "LCD character set (0=normal, 1=KS0074)"
+ range 0 1
+ default 0
+ ---help---
+ Some controllers such as the KS0074 use a somewhat strange character set
+ where many symbols are at unusual places. The driver knows how to map
+ 'standard' ASCII characters to the character sets used by these controllers.
+ Valid values are :
+
+ 0 : normal (untranslated) character set
+ 1 : KS0074 character set
+
+ If you don't know, use the normal one (0).
+
+config PANEL_LCD_PROTO
+ depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+ int "LCD communication mode (0=parallel 8 bits, 1=serial)"
+ range 0 1
+ default 0
+ ---help---
+ This driver now supports any serial or parallel LCD wired to a parallel
+ port. But before assigning signals, the driver needs to know if it will
+ be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires
+ (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals
+ (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits
+ parallel LCD, and 1 for a serial LCD.
