Hi Roger,

Yep.

Shouldn't this be 1 instead? I'm hoping max value is without the shift
based on GPMC_CONFIG1_CLKACTIVATIONTIME_MAX.
Yes, it should. It's a remnant from the change below...
+ * @max Maximum parameter value (after optional @shift).
max should be absolute value, without the shift.
Yes, forgot to change that.
+#define GPMC_GET_RAW_SHIFT(reg, st, end, shift, max, field) \
+ get_gpmc_timing_reg(cs, (reg), (st), (end), (max), field, GPMC_CD_FCLK, (shift), 1, 1)
Is it better to rename this to GPMC_GET_RAW_SHIFT_MAX() as it takes the max parameter.
Ok.
+ GPMC_GET_RAW_SHIFT(GPMC_CS_CONFIG1, 23, 24, 4, 2, "burst-length");
want to define GPMC_CONFIG1_BURSTLENGTH_MAX?
Yes, for consistency. Originally, i was not going to create defines for limits used only in one place, as opposed to WAITMONITORINGTIME and CLKACTIVATIONTIME.
- GPMC_GET_TICKS_CD(GPMC_CS_CONFIG1, 18, 19, "wait-monitoring-ns", GPMC_CD_CLK);
- GPMC_GET_TICKS(GPMC_CS_CONFIG1, 25, 26, "clk-activation-ns");
+ GPMC_GET_TICKS_CD_MAX(GPMC_CS_CONFIG1, 18, 19, GPMC_CONFIG1_WAIT_MON_TIME_MAX, "wait-monitoring-ns", GPMC_CD_CLK);
use GPMC_CONFIG1_WAITMONTIME_MAX to have consistent naming.
I used the naming the other define had. Saw no point in changing them. They go mostly unused anyway.
Might as well change it.

+#define GPMC_SET_ONE_CD(reg, st, end, field, cd) \
+ GPMC_SET_ONE_CD_MAX(reg, st, end, 0, field, GPMC_CD_FCLK)
last parameter should be (cd) instead of GPMC_CD_FCLK.
Ah, copy-paste, there you are again. Luckily this define goes unused, because all GPMC_SET_ONE_CD became GPMC_SET_ONE_CD_MAX anyway.
So I'll delete that. Quite a keen eye, though ;)

Regards,

Robert
