Would something like that be ok ?
#define __fourcc_mod_amlogic_layout_mask 0xf
#define __fourcc_mod_amlogic_options_shift 8
#define __fourcc_mod_amlogic_options_mask 0xf
#define DRM_FORMAT_MOD_AMLOGIC_FBC(__layout, __options) \
fourcc_mod_code(AMLOGIC, \
((__layout) & __fourcc_mod_amlogic_layout_mask) | \
((options) & __fourcc_mod_amlogic_options_mask \
<< __fourcc_mod_amlogic_options_shift))
/* Amlogic FBC Layouts */
/* bla */
#define AMLOGIC_FBC_LAYOUT_BASIC (1ULL)

#define AMLOGIC_FBC_LAYOUT_SCATTER (2ULL)
