spi: fsl_espi: fix read transactions

2026-05-15T11:28:30Z

Since commit 7917c2e35604 ("spi: fsl_espi: fix din offset") MTD is basically broken because any read transaction will get wrong data. While the commit in question will fix simple transfers (where both SPI_XFER_BEGIN and SPI_XFER_END is set), it will break the most common case, where opcode and address is send first and then data comes as a second transfer. This basically reverts commit 7917c2e35604 ("spi: fsl_espi: fix din offset") and make the fix particular for this simple case. Instead of providing two buffers for reading and writing, just malloc one which is used for both. This will work because the data is first written on the SPI bus and then it will be read (and overwite the written data) into the same buffer.

spi: fsl_espi: fix din offset

2026-04-02T12:07:48Z

In the case of SPI_XFER_BEGIN | SPI_XFER_END, the function creates a buffer of double the size of the transaction, so that it can write the data in into the second half. It sets the rx_offset to len, and in the while loop we are setting an internal "din" to buffer + rx_offset. However, at the end of each loop, the driver copies "buffer + 2 * cmd_len" back to the data_in pointer. This commit changes the source of the data to buffer + rx_offset.

spi: spi-uclass: Read chipselect and restrict capabilities

2024-10-09T15:01:54Z

Read chipselect properties from DT which are populated using 'reg' property and save it in plat->cs[] array for later use. Also read multi chipselect capability which is used for parallel-memories and return errors if they are passed on using DT but driver is not capable of handling it.

Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"

2024-05-20T19:35:03Z

As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

treewide: Simply conditions with the new OF_REAL

Use this new Kconfig to simplify the compilation conditions where appropriate. Signed-off-by: Simon Glass

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

dm: Use access methods for dev/uclass private data

2021-01-05T19:24:40Z

Most drivers use these access methods but a few do not. Update them. In some cases the access is not permitted, so mark those with a FIXME tag for the maintainer to check. Signed-off-by: Simon Glass Acked-by: Andy Shevchenko Acked-by: Pratyush Yadav
