We need the tty/serial fixes in here as well. Signed-off-by: Greg Kroah-Hartman

serial: dz: Enable modular build

2026-05-22T09:52:34+00:00

Enable modular build since the driver now has a proper module_exit() handler. There's nothing specific to DZ hardware to prevent driver unloading and reloading from working. Signed-off-by: Maciej W.

serial: max310x: fix compile errors if CONFIG_SPI_MASTER is disabled

2026-05-22T09:38:06+00:00

Since commit 20ffe4b3330a8 ("serial: max310x: allow driver to be built with SPI or I2C"), if I2C is enabled and SPI_MASTER is disabled, we have these compile errors: drivers/tty/serial/max310x.c: In function 'max310x_uart_init': drivers/tty/serial/max310x.c: error: 'max310x_spi_driver' undeclared... drivers/tty/serial/max310x.c: In function ‘max310x_uart_init’: drivers/tty/serial/max310x.c: error: label ‘err_spi_register’ defined but not used... drivers/tty/serial/max310x.c: error: ‘regcfg’ defined but not used Fix by properly encapsulating i2c/spi code/variables in their respective context with IS_ENABLED() macros for CONFIG_I2C and CONFIG_SPI_MASTER. Also fix link failure with SERIAL_MAX310X=y and I2C=m by modifying Kconfig depends.

serial: max310x: allow driver to be built with SPI or I2C

2026-05-11T15:20:18+00:00

If SPI is disabled, the max310x driver cannot be selected. Allow driver to be selected if either I2C or SPI is set. Signed-off-by: Hugo Villeneuve Link: https://patch.msgid.link/20260417-max310x-2-v1-8-b424e105ecac@dimonoff.com Signed-off-by: Greg Kroah-Hartman

serial: qcom: Unify user-visible "Qualcomm" name

2026-04-27T16:28:13+00:00

Various names for Qualcomm as a company are used in user-visible config options: QCOM, Qualcomm and Qualcomm Technologies. Switch to unified "Qualcomm" so it will be easier for users to identify the options when for example running menuconfig.

serial: pic32_uart: allow driver to be compiled on all architectures with COMPILE_TEST

2026-03-12T14:25:04+00:00

This driver currently only supports builds against a PIC32 target, or with COMPILE_TEST on MIPS. Now that commit 24cad1a22848 ("serial: pic32_uart: update include to use pic32.h from platform_data") is merged, it's possible to compile this driver on other architectures. To avoid future breakage of this driver in the future, let's update the Kconfig so that it can be built with COMPILE_TEST enabled on all architectures.

serial: tegra: remove Kconfig dependency on APB DMA controller

2026-03-12T14:24:48+00:00

This driver runs also on SoCs without a Tegra20 APB DMA controller (e.g. Tegra234). Remove the Kconfig dependency on TEGRA20_APB_DMA, and remove reference to the APB DMA controller from the Kconfig help text.

serial: remove drivers for espressif esp32

2026-03-12T14:06:52+00:00

These drivers were added about 3 years ago, and depend on the XTENSA_PLATFORM_ESP32 config option which has never existed, so no device can actually use them. They can only be compiled with COMPILE_TEST. In a previous conversation [1], Greg suggested removing the drivers, and Max, the original submitter of the drivers, agreed due to a lack of foreseeable development.

serial: SH_SCI: improve "DMA support" prompt

Having a prompt of "DMA support" suddenly appear during a "make oldconfig" can be confusing. Add a little helpful text to the prompt message. Fixes: 73a19e4c0301 ("serial: sh-sci: Add DMA support.")

serial: Kconfig: fix ordering of entries for menu display

2026-01-16T13:25:16+00:00

Improve the "Non-8250 serial port support" menu so that entries in it are displayed in a better order (_CONSOLE after its driver) and so that intervening symbols don't break up the dependency list, allowing menu entries to be displayed with proper indentation.
