Now that CONFIG_PANEL (the legacy parallel port LCD support) has been permanently purged from the Kconfig tree, its associated documentation is a ghost reference. Remove the orphaned lcd-panel-cgram.rst file and clean up its entry from the admin-guide index to prevent any future Sphinx broken links.

+++ /dev/null@@ -1,27 +0,0 @@ -====================================== -Parallel port LCD/Keypad Panel support -====================================== - -Some LCDs allow you to define up to 8 characters, mapped to ASCII -characters 0 to 7. The escape code to define a new character is -'\e[LG' followed by one digit from 0 to 7, representing the character -number, and up to 8 couples of hex digits terminated by a semi-colon -(';'). Each couple of digits represents a line, with 1-bits for each -illuminated pixel with LSB on the right. Lines are numbered from the -top of the character to the bottom. On a 5x7 matrix, only the 5 lower -bits of the 7 first bytes are used for each character. If the string -is incomplete, only complete lines will be redefined. Here are some -examples:: - - printf "\e[LG0010101050D1F0C04;" => 0 = [enter] - printf "\e[LG1040E1F0000000000;" => 1 = [up] - printf "\e[LG2000000001F0E0400;" => 2 = [down] - printf "\e[LG3040E1F001F0E0400;" => 3 = [up-down] - printf "\e[LG40002060E1E0E0602;" => 4 = [left] - printf "\e[LG500080C0E0F0E0C08;" => 5 = [right] - printf "\e[LG60016051516141400;" => 6 = "IP" - - printf "\e[LG00103071F1F070301;" => big speaker - printf "\e[LG00002061E1E060200;" => small speaker - -Willy
