From 07ba9e7be423423043c5090a2f395c0da26e1b3d Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov <dmitry.torokhov@gmail.com> Date: Fri, 18 Jan 2019 11:18:17 -0800 Subject: Input: document meanings of KEY_SCREEN and KEY_ZOOM It is hard to say what KEY_SCREEN and KEY_ZOOM mean, but historically DVB folks have used them to indicate switch to full screen mode. Later, they converged on using KEY_ZOOM to switch into full screen mode and KEY)SCREEN to control aspect ratio (see Documentation/media/uapi/rc/rc-tables.rst). Let's commit to these uses, and define: - KEY_FULL_SCREEN (and make KEY_ZOOM its alias) - KEY_ASPECT_RATIO (and make KEY_SCREEN its alias) Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> --- include/uapi/linux/input-event-codes.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'include/uapi') diff --git a/include/uapi/linux/input-event-codes.h b/include/uapi/linux/input-event-codes.h index ae366b87426a..bc5054e51bef 100644 --- a/include/uapi/linux/input-event-codes.h +++ b/include/uapi/linux/input-event-codes.h @@ -439,10 +439,12 @@ #define KEY_TITLE 0x171 #define KEY_SUBTITLE 0x172 #define KEY_ANGLE 0x173 -#define KEY_ZOOM 0x174 +#define KEY_FULL_SCREEN 0x174 /* AC View Toggle */ +#define KEY_ZOOM KEY_FULL_SCREEN #define KEY_MODE 0x175 #define KEY_KEYBOARD 0x176 -#define KEY_SCREEN 0x177 +#define KEY_ASPECT_RATIO 0x177 /* HUTRR37: Aspect */ +#define KEY_SCREEN KEY_ASPECT_RATIO #define KEY_PC 0x178 /* Media Select Computer */ #define KEY_TV 0x179 /* Media Select TV */ #define KEY_TV2 0x17a /* Media Select Cable */ -- cgit v1.2.3
