72cd8e57a9 Tiva Timer: Allow timeout interrupts even if the reload value is zero. That is the value that is need to get an interrupt on the wrap from 0xffffffff to 0x00000000 2015-01-13 08:29:25 -06:00

b1697c7ff4 Tiva Timer: Add conditional compilation to enable/disable each timer feature. Not only does this reduce the footprint by suppressing unused features, it also protects from partially implemented features that are now conditioned on EXPERIMENTAL 2015-01-13 07:49:20 -06:00

1842525cc2 MMCSD SDIO: Add support for a new SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop to pool the card R1 start to determine when the card was ready for the next transfer. That busy-wait can be quite long -- hundreds of milliseconds. And alternative is to look the the SD D0 pin which will change state when the card is no longer busy.
This logic implements a change the avoids the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, then waiting for the card to becom ready without taking up CPU cycles.

This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE and is currenlty only implemented for the STM32 SDIO driver.
