I've taken Hans Schillstrom's version of rcb8270_led-0001.bin (which is
based on DENX status_led.c) and "generalized" it for my purposes (I have
LED's on more that one port and not all pins can be LED's) (This is used
on a TQM8260). This also has only been tested briefly...
What was done:
1.) put back in DENX copyright; ;^)
2.) removed unknown include files;
3.) put in compile option to NOT initialize a port pin during module
install, see #define DO_NOT_INIT_PORT and #ifndef DO_NOT_INIT_PORT;
4.) added "used" field to control structure to specify if LED was ever
used (set in statusled_open());
5.) put code in statusled_cleanup() that will only shut off a LED if the
LED was ever used (opened);
In the led_dev_t led_dev[] control structure, all of the port A & D pins
are specified (for my needs) but not all are used. (The project that I
am using this for is a "moving" target and not all of the port pins have
been specified.) Therefore in the load script, only create devices that
_ARE_ LED's. Device minor numbers for port A is the port pin number and
for port D it is the port pin number times 2.
