Thu, 13 Feb 2025 12:56:12 +0000

serial: tegra-utc: Add driver for Tegra UART Trace Controller (UTC)The Tegra264 SoC supports the UART Trace Controller (UTC), which allowsmultiple firmware clients (up to 16) to share a single physical UART.Each client is provided with its own interrupt and has access to a128-character wide FIFO for both transmit (TX) and receive (RX)operations.Add tegra-utc driver to support Tegra UART Trace Controller (UTC)client.Signed-off-by: Kartik Rajput Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20250213125612.4705-3-kkartik@nvidia.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/serial/Kconfig

c08b0f2c - Revert "tty/serial: Add kgdb_nmi driver"

Wed, 29 Jan 2025 16:25:50 +0000

Revert "tty/serial: Add kgdb_nmi driver"This reverts commit 0c57dfcc6c1d037243c2f8fbf62eab3633326ec0.The functionality was supoosed to be used by a later patch in theseries that never landed [1]. Drop it.NOTE: part of functionality was already reverted by commit39d0be87438a ("serial: kgdb_nmi: Remove unused knock code"). Also notethat this revert is not a clean revert given code changes that havehappened in the meantime.It's obvious that nobody is using this code since the two exposedfunctions (kgdb_register_nmi_console() andkgdb_unregister_nmi_console()) are both no-ops if"arch_kgdb_ops.enable_nmi" is not defined. No architectures define it.[1] https://lore.kernel.org/lkml/1348522080-32629-9-git-send-email-anton.vorontsov@linaro.org/Signed-off-by: Douglas Anderson Acked-by: Andy Shevchenko Link: URL [1]Link: https://lore.kernel.org/r/20250129082535.1.Ia095eac1ae357f87d23e7af2206741f5d40788f1@changeidSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/serial/Kconfig

tty: serial: handle HAS_IOPORT dependenciesIn a future patch HAS_IOPORT=n will disable inb()/outb() and friends atcompile time. We thus need to add HAS_IOPORT as dependency for thosedrivers using them unconditionally. Some 8250 serial drivers supportMMIO only use, so fence only the parts requiring I/O ports and print anerror message if a device can't be supported with the currentconfiguration.Co-developed-by: Arnd Bergmann Signed-off-by: Arnd Bergmann Acked-by: Greg Kroah-Hartman Reviewed-by: Maciej W.

98a59cd2 - serial: liteuart: drop obsolete dependency on COMPILE_TEST

Fri, 25 Nov 2022 13:27:56 +0000

serial: liteuart: drop obsolete dependency on COMPILE_TESTSince commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), itis possible to test-build any driver which depends on OF on anyarchitecture by explicitly selecting OF. Therefore depending onCOMPILE_TEST as an alternative is no longer needed.It is actually better to always build such drivers with OF enabled,so that the test builds are closer to how each driver will actually bebuilt on its intended target. Building them without OF may not testmuch as the compiler will optimize out potentially large parts of thecode. In the worst case, this could even pop false positive warnings.Dropping COMPILE_TEST here improves the quality of our testing andavoids wasting time on non-existent issues.Signed-off-by: Jean Delvare Cc: Karol Gugala Cc: Mateusz Holenko Cc: Gabriel Somlo Cc: Joel Stanley Cc: Greg Kroah-Hartman Acked-by: Gabriel Somlo Link: https://lore.kernel.org/r/20221125142756.3e51a28d@endymion.delvareSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/tty/serial/Kconfig
