Its enough to freeze the clock instead. When disabling the + whole peripheral, the next wakeup-interrupt comes up with an disabled + clocking. The unfreeze clock has no effect, because the master clock + is disabled. This makes all registers, including the IDR unwriteable + and the IRQ falls in an endless loop blocking the whole system. + Furthermore the disabling of the peripheral clock prevents hotplugging + or reconnecting the USB. From Frank Benkert (2015-05-25). + * drivers/lcd: Add support for PCF8574 LCD Backpack driver. This driver + supports an interface board that is based on the PCF8574 io expander + and supports the HD44780-based (or compatible) LCD modules.

Due to a wrong assumption concerning the behavior + directly after the start of the timer/counter the function + sam_oneshot_cancel(…) calculates the wrong remaining time. The code + assumes that the counter register is zero directly after the start of + the timer, but this is not true. To start the time/counter a software + trigger is invoked, this trigger starts the timer/count and sets the + counter register to zero, but the reset of the counter register is not + performed instantly. According to the datasheet: "The counter can be + reset by a trigger. In this case, the counter value passes to zero on + the next valid edge of the selected clock.” Thus the counter is set to + zero between 0 and USEC_PER_TICK microseconds after the clock was + started. + In my fix I use the freerun count value to determine if at least one + tick passed since the start of the timer and thus if the value of the + oneshot counter is correct. I also tried to use the function + up_timer_gettime(…) to achieve this but, at least if compiled with no + optimization the problem vanishes without using the value of the + function, the function call takes too long. + Another problem treated in the fix is that if the oneshot timer/counter + is canceled, we only know the remaining time with a precision of + USEC_PER_TICK microseconds. This means the calculated remaining time + is between 0 and USEC_PER_TICK microseconds too long. To fix this I + subtract one tick if the calculated remaining time is greater than one + tick and otherwise set the remaining time to zero. By doing so the + measured times are much more precise as without it.
