serial: sh-sci: Add support for RZ/T2H SCI

2025-07-09T11:45:30+00:00

Define a new RSCI port type, and the RSCI 32 bits registers set. The RZ/T2H SCI has a a fifo, and a quite different set of registers from the original SH SCI ones. DMA is not supported yet.

serial: tegra-utc: Add driver for Tegra UART Trace Controller (UTC)

2025-02-14T09:06:50+00:00

The Tegra264 SoC supports the UART Trace Controller (UTC), which allows multiple firmware clients (up to 16) to share a single physical UART. Each client is provided with its own interrupt and has access to a 128-character wide FIFO for both transmit (TX) and receive (RX) operations. Add tegra-utc driver to support Tegra UART Trace Controller (UTC) client.

Revert "tty/serial: Add kgdb_nmi driver"

2025-02-14T09:05:43+00:00

This reverts commit 0c57dfcc6c1d037243c2f8fbf62eab3633326ec0. The functionality was supoosed to be used by a later patch in the series that never landed [1]. Drop it. NOTE: part of functionality was already reverted by commit 39d0be87438a ("serial: kgdb_nmi: Remove unused knock code"). Also note that this revert is not a clean revert given code changes that have happened in the meantime. It's obvious that nobody is using this code since the two exposed functions (kgdb_register_nmi_console() and kgdb_unregister_nmi_console()) are both no-ops if "arch_kgdb_ops.enable_nmi" is not defined. No architectures define it.

serial: sc16is7xx: rename Kconfig CONFIG_SERIAL_SC16IS7XX_CORE

2024-06-04T12:10:28+00:00

Commit d49216438139 ("serial: sc16is7xx: split into core and I2C/SPI parts (core)") renamed SERIAL_SC16IS7XX_CORE by SERIAL_SC16IS7XX. This means that some configs should have been updated when I submitted the original patch, but unfortunately they were not. Geert mentioned for example: arch/mips/configs/cu1??0-neo_defconfig Rename SERIAL_SC16IS7XX to SERIAL_SC16IS7XX_CORE so that existing configs will still work correctly.

serial: sc16is7xx: split into core and I2C/SPI parts (core)

2024-04-11T12:08:08+00:00

Split the common code from sc16is7xx driver and move the I2C and SPI bus parts into interface-specific source files. sc16is7xx becomes the core functions which can support multiple bus interfaces like I2C and SPI. No functional changes intended. Also simplify and improve Kconfig entries. - Capitalize SPI keyword for consistency - Display list of supported ICs each on a separate line (and aligned) to facilitate locating a specific IC model - Add Manufacturer name at start of description string - Add UART keyword to description string Suggested-by: Andy Shevchenko Signed-off-by: Hugo Villeneuve Link: https://lore.kernel.org/r/20240409154253.3043822-4-hugo@hugovil.com Signed-off-by: Greg Kroah-Hartman
