* Name: board_ioctl
|
|
*
|
|
* Description:
|
|
* The "landing site" for much of the boardctl() interface. Generic board-
|
|
* control functions invoked via ioctl() get routed through here.
|
|
*
|
|
* Since we don't do anything unusual at the moment, this function
|
|
* accomplishes nothing except avoid a missing-function linker error if
|
|
* CONFIG_BOARDCTL_IOCTL is selected.
|
|
*
|
|
* Input Parameters:
|
|
* cmd - IOCTL command being requested.
|
|
* arg - Arguments for the IOCTL.
|
|
*
|
|
* Returned Value:
|
|
* we don't yet support any boardctl IOCTLs. This function always returns
|
|
* -ENOTTY which is the standard IOCTL return value when a command is not
|
|
* supported
|
|
*
