From: Bin Meng <bin.m...@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 disabled - remove imx_spi_update_irq() in imx_spi_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 v4: - adujst the patch 2,3 order - rename imx_spi_soft_reset() to imx_spi_hard_reset() to avoid confusion - s/normal/common/ in the commit message - log the burst length value in the log message Changes in v3: - new patch: remove imx_spi_update_irq() in imx_spi_reset() - Move the chip selects disable out of imx_spi_reset() - new patch: log unimplemented burst length - Simplify the tx fifo endianness handling Changes in v2: - Fix the "Fixes" tag in the commit message - Use ternary operator as Philippe suggested Bin Meng (5): hw/ssi: imx_spi: Use a macro for number of chip selects supported hw/ssi: imx_spi: Remove imx_spi_update_irq() in imx_spi_reset() hw/ssi: imx_spi: Log unimplemented burst length 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 when controller is disabled include/hw/ssi/imx_spi.h | 5 ++++- hw/ssi/imx_spi.c | 42 ++++++++++++++++++++++++++++------------ 2 files changed, 34 insertions(+), 13 deletions(-) -- 2.25.1
