From: Bin Meng <bin.meng@windriver.com>
This series fixes a bunch of bugs in current implementation of the imx
spi controller, including the following issues:
- chip select signal was not lower down when spi controller is reset
- transfer incorrect data when the burst length is larger than 32 bit
- spi controller tx and rx fifo endianness is incorrect
Tested with upstream U-Boot v2020.10 (polling mode) and VxWorks 7
(interrupt mode).
Changes in v2:
- Fix the "Fixes" tag in the commit message
- Use ternary operator as Philippe suggested
Bin Meng (3):
hw/ssi: imx_spi: Use a macro for number of chip selects supported
hw/ssi: imx_spi: Correct the burst length > 32 bit transfer logic
hw/ssi: imx_spi: Correct tx and rx fifo endianness
Xuzhou Cheng (1):
hw/ssi: imx_spi: Disable chip selects in imx_spi_reset()
