You mean this? -#define ACCESS_INTR_MASK BIT(0) -#define ACCESS_NO_IRQ_SUSPEND BIT(1) -#define ARBITRATION_SEMAPHORE BIT(2) - -#define MODEL_MSCC_OCELOT BIT(8) -#define MODEL_BAIKAL_BT1 BIT(9) -#define MODEL_AMD_NAVI_GPU BIT(10) -#define MODEL_MASK GENMASK(11, 8) +#define ACCESS_INTR_MASK 0x00 +#define ACCESS_NO_IRQ_SUSPEND 0x01 +#define ARBITRATION_SEMAPHORE 0x02 + +#define MODEL_MSCC_OCELOT 0x08 +#define MODEL_BAIKAL_BT1 0x09 +#define MODEL_AMD_NAVI_GPU 0x0a +#define MODEL_MASK 0x78 I actually like more bitfield to plain numbers.
