+Subject: [Armadeus-forum] Found bug in pwm-mxs.c
+
+Hello folks,
+
+ I found a bug in the pwm-mxs.c driver for the i.MX28 platform.
+
+ The driver computes from the desired period which clock divider it
+should be using. This computation assumes that the link between the
+register value and the actual divider value is raising 2 to the power of
+the registry value.
+
+ div = 1 << regvalue
+
+ This is true only for the first 5 values out of 8. Next values are
+64, 256 and, 1024.
+ This affects only the user only if he requests a period > 0.04369s.
+ I solved this by replacing the computation of the divider value with
+a lookup table.
+
+ If I should provide it in a different manner for it to be included in
+the kernel, please let me know.
+
+Best regards
+
