![]() Bugfix to spi_bitbang infrastructure: make sure to always set transfer parameters on the first pass through the message's per-transfer loop. This can matter with drivers that replace the per-word or per-buffer transfer primitives, on busses with multiple SPI devices. Previously, this could have started messages using the settings left after previous messages. The problem was observed when a high speed chip (m25p80 type flash) was running very slowly because a low speed device (avr8 microcontroller) had previously used the bus. Similar faults could have driven the low speed device too fast, or used an unexpected word size. Acked-by: Steven A.
