2016-10-06auxdisplay: img-ascii-lcd: driver for simple ASCII LCD displaysPaul Burton
Add a driver for simple ASCII LCD displays found on the MIPS Boston, Malta & SEAD3 development boards. The Boston display is an independent memory mapped device with a simple memory mapped 8 byte register space containing the 8 ASCII characters to display. The Malta display is exposed as part of the Malta board registers, and provides 8 registers each of which corresponds to one of the ASCII characters to display. The SEAD3 display is slightly more complex, exposing an interface to an S6A0069 LCD controller via registers provided by the boards CPLD. However although the displays differ in their register interface, we require similar functionality on each board so abstracting away the differences within a single driver allows us to share a significant amount of code & ensure consistent behaviour. The driver displays the Linux kernel version as the default message, but allows the message to be changed via a character device. Messages longer then the number of characters that the display can show will scroll. This provides different behaviour to the existing LCD display code for the MIPS Malta or MIPS SEAD3 platforms in the following ways: - The default string to display is not "LINUX ON MALTA" or "LINUX ON SEAD3" but "Linux" followed by the version number of the kernel (UTS_RELEASE). - Since that string tends to be significantly longer it scrolls twice as fast, moving every 500ms rather than every 1s. - The LCD won't be updated until the driver is probed, so it doesn't provide the early "LINUX" string.

2007-06-01cfag12864bfb: Use sys_ instead of cfb_ framebuffer accessorsAvuton Olrich
Because the framebuffer memory is allocated system RAM, use the sys_ drawing libraries. It also fixes the following compile error: LD .tmp_vmlinux1 drivers/built-in.o:(.data+0x8b48): undefined reference to `cfb_fillrect' drivers/built-in.o:(.data+0x8b50): undefined reference to `cfb_copyarea' drivers/built-in.o:(.data+0x8b58): undefined reference to `cfb_imageblit' [adaplas] Use fb_sys_read/write for the same reasons as above.

2007-02-11[PATCH] drivers: add LCD supportMiguel Ojeda Sandonis
Add support for auxiliary displays, the ks0108 LCD controller, the cfag12864b LCD and adds a framebuffer device: cfag12864bfb. - Add a "auxdisplay/" folder in "drivers/" for auxiliary display drivers. - Add support for the ks0108 LCD Controller as a device driver. (uses parport interface) - Add support for the cfag12864b LCD as a device driver. (uses ks0108 LCD Controller driver) - Add a framebuffer device called cfag12864bfb. (uses cfag12864b LCD driver) - Add the usual Documentation, includes, Makefiles, Kconfigs, MAINTAINERS, CREDITS... - Miguel Ojeda will maintain all the stuff above.
