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.
