According to the driver the device has registers up to 0xff?
That is indeed true. But from address 0x29 on (0x26 to 0x28 are
reserved) the register width varies between 20, 12 and 8 bytes, which
I'm afraid the register map is unable to represent.
/* device registers */
+#define TAS571X_CLK_CTRL_REG 0x00
+#define TAS571X_DEV_ID_REG 0x01
+#define TAS571X_ERR_STATUS_REG 0x02
+#define TAS571X_SYS_CTRL_1_REG 0x03
These look like volatile registers but the device has a register cache
and we're not adding a list of volatile registers (or readable registers
for that matter).
That's a good point, thanks! 0x03 is a regular RW register but 0x00 to
0x02 are indeed volatile.
Is it better to make them read-only, or volatile?
Petr
