From 6d686145c86c9712db1547f66bebb7131979c61b Mon Sep 17 00:00:00 2001 From: Eden Mikitas Date: Tue, 2 Jun 2020 13:44:34 +0100 Subject: hw/ssi/imx_spi: Removed unnecessary cast of rx data received from slave When inserting the value retrieved (rx) from the spi slave, rx is pushed to rx_fifo after being cast to uint8_t. rx_fifo is a fifo32, and the rx register the driver uses is also 32 bit. This zeroes the 24 most significant bits of rx. This proved problematic with devices that expect to use the whole 32 bits of the rx register.
