Vladimir Kondratyev 5adcec04b5 intelspi: Add support for ddb/kdb -compatible polled mode ... Required for Apple and Microsoft -compatible HID-over-SPI drivers. Most logic was already implemented in commit 3c08673438 "spibus: extend API: add cs_delay ivar, KEEP_CS and NO_SLEEP flags". It dissallowed driver sleeps in the interrupt context. This commit extends this feature to handle ddb/kdb context with following: - Skip driver locking if SPI functions were called from kdb/ddb. - Reinitialize controller if kdb/ddb initiated SPI transfer has interrupted another already running one. Does not work very reliable yet. Reviewed by: manu Differential Revision: https://reviews.freebsd.org/D41247		2023-08-03 19:10:50 +03:00
