Michael Hope 8181eede5d drivers: spi: ensure the first byte has been loaded in the TX fast path ... The SAM0 has a data register and a shift register. Data that is written to the data register is transferred to the shift register by the peripheral. On the SAMD51, the CPU is fast enough that the first data write hasn't been transferred to the shift register by the time the next data write occurs, causing the second write to be dropped, causing the receiver to wait forever. Fix by spinning until the data register is empty. Signed-off-by: Michael Hope <mlhx@google.com>		2020-07-06 10:01:35 -04:00
