5ccf4028 - mux: mmio: drop obsolete dependency on COMPILE_TEST

Wed, 31 May 2023 21:53:27 +0000

mux: mmio: 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.As a minor optimization, this also lets us drop of_match_ptr(), as wenow know what it will resolve to, we might as well save cpp some work.Signed-off-by: Jean Delvare Signed-off-by: Peter Rosin Link: https://lore.kernel.org/r/bc790b4e-1cb4-4ef5-3da8-9d0e6b613bc7@axentia.seSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/mux/Kconfig

mux: adgs1408: new driver for Analog Devices ADGS1408/1409 muxThis patch adds basic support for Analog Device ADGS1408/09 SPI muxcontroller.The device is probed and set to a disabled state. It uses the new muxcontroller framework.Signed-off-by: Mircea Caprioru Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/mux/Kconfig

0edff03d - mux: add SPDX identifiers to all mux source files

Thu, 28 Dec 2017 23:22:55 +0000

mux: add SPDX identifiers to all mux source filesRemove all free-text license texts.This is done on a quest to remove the 700+ different ways that files inthe kernel describe the GPL license text.No copyright headers or other non-license-description text was removed.Reviewed-by: Philippe Ombredanne Acked-by: Philipp Zabel Signed-off-by: Peter Rosin Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/mux/Kconfig

4c19c0ec - mux: remove the Kconfig question for the subsystem

Tue, 04 Jul 2017 08:22:44 +0000

mux: remove the Kconfig question for the subsystemThe MULTIPLEXER question in the Kconfig might be confusing and isof dubious value. Remove it. This makes consumers responsible forselecting MULTIPLEXER, which they already do.Signed-off-by: Peter Rosin Reported-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/mux/Kconfig

Sun, 14 May 2017 19:51:07 +0000

mux: gpio: add mux controller driver for gpio based multiplexersThe driver builds a single multiplexer controller using a numberof gpio pins. For N pins, there will be 2^N possible multiplexerstates. The GPIO pins can be connected (by the hardware) to severalmultiplexers, which in that case will be operated in parallel.Reviewed-by: Jonathan Cameron Signed-off-by: Peter Rosin Reviewed-by: Philipp Zabel Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/mux/Kconfig

a3b02a9c - mux: minimal mux subsystem

Sun, 14 May 2017 19:51:06 +0000

mux: minimal mux subsystemAdd a new minimalistic subsystem that handles multiplexer controllers.When multiplexers are used in various places in the kernel, and thesame multiplexer controller can be used for several independent things,there should be one place to implement support for said multiplexercontroller.A single multiplexer controller can also be used to control severalparallel multiplexers, that are in turn used by different subsystemsin the kernel, leading to a need to coordinate multiplexer accesses.The multiplexer subsystem handles this coordination.Thanks go out to Lars-Peter Clausen, Jonathan Cameron, Rob Herring,Wolfram Sang, Paul Gortmaker, Dan Carpenter, Colin Ian King, GregKroah-Hartman and last but certainly not least to Philipp Zabel forhelpful comments, reviews, patches and general encouragement!Reviewed-by: Jonathan Cameron Signed-off-by: Peter Rosin Reviewed-by: Philipp Zabel Tested-by: Philipp Zabel Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/mux/Kconfig
