serial: 8250_dw: Add ACPI ID for Granite Rapids-D UART

2023-12-07T01:48:56+00:00

Granite Rapids-D has an additional UART that is enumerated via ACPI. Add ACPI ID for it. Signed-off-by: Andy Shevchenko Cc: stable Link: https://lore.kernel.org/r/20231205195524.2705965-1-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

serial: 8250: 8250_omap: Clear UART_HAS_RHR_IT_DIS bit

2023-11-23T20:21:10+00:00

This fixes commit 439c7183e5b9 ("serial: 8250: 8250_omap: Disable RX interrupt after DMA enable") which unfortunately set the UART_HAS_RHR_IT_DIS bit in the UART_OMAP_IER2 register and never cleared it.

serial: 8250_omap: Add earlycon support for the AM654 UART controller

2023-11-23T20:20:56+00:00

Currently there is no support for earlycon on the AM654 UART controller. This commit adds it. Signed-off-by: Ronald Wahl Reviewed-by: Vignesh Raghavendra Link: https://lore.kernel.org/r/20231031131242.15516-1-rwahl@gmx.de Cc: stable Signed-off-by: Greg Kroah-Hartman

serial: 8250: 8250_omap: Do not start RX DMA on THRI interrupt

2023-11-23T20:20:16+00:00

Starting RX DMA on THRI interrupt is too early because TX may not have finished yet. This change is inspired by commit 90b8596ac460 ("serial: 8250: Prevent starting up DMA Rx on THRI interrupt") and fixes DMA issues I had with an AM62 SoC that is using the 8250 OMAP variant.

tty: 8250: Fix IS-200 PCI ID comment

2023-10-21T16:54:02+00:00

Fix the PCI comment for the IS-200 card. The PCI ID for the IS-200 is 0x0d80, and the definition used (PCI_DEVICE_ID_INTASHIELD_IS200) is indeed 0x0d80, clarify that by fixing the comment as its neighbouring cards are all at 0x0020 offsets.

tty: 8250: Add Brainboxes Oxford Semiconductor-based quirks

2023-10-21T16:54:02+00:00

Some of the later revisions of the Brainboxes PX cards are based on the Oxford Semiconductor chipset. Due to the chip's unique setup these cards need to be initialised. Previously these were tested against a reference card with the same broken baudrate on another PC, cancelling out the effect. With this patch they work and can transfer/receive find against an FTDI-based device. Add all of the cards which require this setup to the quirks table. Thanks to Maciej W. Rozycki for clarification on this chip. Fixes: ef5a03a26c87 ("tty: 8250: Add support for Brainboxes PX cards.")
