pnp: Add some default functions to enter/exit config state
Implement some common default functions to enter and exit the configuration state. Also provide default pnp_mode_ops for common enter()/exit() function pairs. The following cocci ensures their use: @ mode_match @ identifier enter, exit, ops; @@ struct pnp_mode_ops ops = { .enter_conf_mode = enter, .exit_conf_mode = exit, }; @ enter_match_8787 @ identifier mode_match.enter, dev; @@ enter(...) { outb(0x87, dev->path.pnp.port); outb(0x87, dev->path.pnp.port); } @ depends on enter_match_8787 @ identifier mode_match.enter, mode_match.ops; @@ struct pnp_mode_ops ops = { - .enter_conf_mode = enter, + .enter_conf_mode = pnp_enter_conf_mode_8787, }; @ enter_match_55 @ identifier mode_match.enter, dev; @@ enter(...) { outb(0x55, dev->path.pnp.port); } @ depends on enter_match_55 @ identifier mode_match.enter, mode_match.ops; @@ struct pnp_mode_ops ops = { - .enter_conf_mode = enter, + .enter_conf_mode = pnp_enter_conf_mode_55, }; @ depends on enter_match_8787 || enter_match_55 @ identifier mode_match.enter; @@ -enter(...) {...} @ exit_match_aa @ identifier mode_match.exit, dev; @@ exit(...) { outb(0xaa, dev->path.pnp.port); } @ depends on exit_match_aa @ identifier mode_match.exit, mode_match.ops; @@ struct pnp_mode_ops ops = { - .exit_conf_mode = exit, + .exit_conf_mode = pnp_exit_conf_mode_aa, }; @ depends on exit_match_aa @ identifier mode_match.exit; @@ -exit(...) {...} @ depends on enter_match_8787 || enter_match_55 || exit_match_aa @ @@ #include <device/pnp.h> +#include <superio/conf_mode.h> @ mode_match_55_aa @ identifier ops; @@ struct pnp_mode_ops ops = { .enter_conf_mode = pnp_enter_conf_mode_55, .exit_conf_mode = pnp_exit_conf_mode_aa, }; @@ identifier mode_match_55_aa.ops; @@ -struct pnp_mode_ops ops = {...}; @@ identifier mode_match_55_aa.ops, devops; @@ struct device_operations devops = { - .ops_pnp_mode = &ops, + .ops_pnp_mode = &pnp_conf_mode_55_aa, }; @ mode_match_8787_aa @ identifier ops; @@ struct pnp_mode_ops ops = { .enter_conf_mode = pnp_enter_conf_mode_8787, .exit_conf_mode = pnp_exit_conf_mode_aa, }; @@ identifier mode_match_8787_aa.ops; @@ -struct pnp_mode_ops ops = {...}; @@ identifier mode_match_8787_aa.ops, devops; @@ struct device_operations devops = { - .ops_pnp_mode = &ops, + .ops_pnp_mode = &pnp_conf_mode_8787_aa, }; Change-Id: I1480336b54523cc95210d99cf31c1a0b3a14b464 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: http://review.coreboot.org/3484 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
