serial: cortina: check RX FIFO status before reading data

2026-06-23T18:37:02Z

ca_serial_getc() reads from the URX_DATA register unconditionally without first checking whether the RX FIFO contains valid data. When the FIFO is empty, this returns whatever stale value is in the register, which the DM serial framework interprets as a valid character. The DM serial framework expects getc() to return -EAGAIN when no data is available, so it can handle retries and call schedule() to service the watchdog between attempts. Add a check of the UINFO register's UINFO_RX_FIFO_EMPTY bit before reading URX_DATA, returning -EAGAIN when no data is pending. This is consistent with how ca_serial_putc() already checks UINFO_TX_FIFO_FULL before writing. Signed-off-by: Naveen Kumar Chaudhary

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

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09Z

This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25Z

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass
