Subject: [PATCH v2 00/10] spi: dw: Add support for DUAL/QUAD/OCTAL modes
Date: Fri, 2 Apr 2021 19:05:05 -0400 [thread overview]
Message-ID: <20210402230515.177825-1-seanga2@gmail.com> (raw)
This series adds support for enhanced SPI modes. It was tested on a K210 (DWC
SSI with QSPI flash).
If anyone has a designware device with QSPI flash attached (especially a DW SSI
APB device), I'd greatly appreciate them testing out this patch series. Given
that there has been no testing of v2 over the past month, I don't think lack of
testing should hold up this series.
Changes in v3:
- Dropped merged patches
- Rebased on u-boot/master
Changes in v2:
- Add more information to exec_op debug message
- Actually mask interrupts
- Merge CAP_{DUAL,QUAD,OCTAL} into CAP_ENHANCED
- Fix some inconsistencies in register naming and usage
- Moved some hunks between commits so things make more sense
