fcbfe812 - Kconfig: introduce HAS_IOPORT option and select it as necessary

In a future patch HAS_IOPORT=n will disable compilation ofthe I/O accessor functions inb()/outb() and friends on architectureswhich can not meaningfully support legacy I/O spaces such as s390.The following architectures do not select HAS_IOPORT:* ARC* C-SKY* Hexagon* Nios II* OpenRISC* s390* User-Mode Linux* XtensaAll other architectures select HAS_IOPORT at least conditionally.The "depends on" relations on HAS_IOPORT in drivers as well as ifdefsfor HAS_IOPORT specific sections will be added in subsequent patches ona per subsystem basis.Co-developed-by: Arnd Bergmann Signed-off-by: Arnd Bergmann Acked-by: Johannes Berg # for ARCH=umAcked-by: Geert Uytterhoeven Signed-off-by: Niklas Schnelle Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/bus/Kconfig

97d485ed - bus: add driver for initializing the SSC bus on (some) qcom SoCs

Mon, 11 Apr 2022 07:21:55 +0000

bus: add driver for initializing the SSC bus on (some) qcom SoCsAdd bindings for the AHB bus which exposes the SSC (Snapdragon Sensor Core)block in the global address space. This bus (and the SSC block itself) ispresent on certain qcom SoCs.In typical configuration, this bus (as some of the clocks and registersthat we need to manipulate) is not accessible to Linux, and the resourceson this bus are indirectly accessed by communicating with a hexagon CPUcore residing in the SSC block. In this configuration, the hypervisor isthe one performing the bus initialization for the purposes of bringingthe hexagon CPU core out of reset.However, it is possible to change the configuration, in which case thisdriver will initialize the bus.In combination with drivers for resources on the SSC bus, this driver canaid in debugging, and for example with a TLMM driver can be used todirectly access SSC-dedicated GPIO pins, removing the need to committo a particular usecase during hw design.Finally, until open firmware for the hexagon core is available, thisapproach allows for using sensors hooked up to SSC-dedicated GPIO pinson mainline Linux simply by utilizing the existing in-tree drivers forthese sensors.Signed-off-by: Michael Srba Reviewed-by: Jeffrey Hugo Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20220411072156.24451-5-michael.srba@seznam.cz List of files: /linux-6.15/drivers/bus/Kconfig

a579fcfa - c6x: remove architecture

Mon, 18 Jan 2021 11:45:46 +0000

c6x: remove architectureThe c6x architecture was added to the kernel in 2011 at a time whenrunning Linux on DSPs was widely seen as the logical evolution.It appears the trend has gone back to running Linux on Arm based SoCswith DSP, using a better supported software ecosystem, and having betterreal-time behavior for the DSP code. An example of this is TI's ownKeystone2 platform.The upstream kernel port appears to no longer have any users. MarkSalter remained avaialable to review patches, but mentioned thathe no longer has access to working hardware himself. Without anyusers, it's best to just remove the code completely to reduce thework for cross-architecture code changes.Many thanks to Mark for maintaining the code for the past ten years.Link: https://lore.kernel.org/lkml/41dc7795afda9f776d8cd0d3075f776cf586e97c.camel@redhat.com/Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/bus/Kconfig

Tue, 26 May 2020 12:59:27 +0000

bus: Add Baikal-T1 APB-bus driverBaikal-T1 AXI-APB bridge is used to access the SoC subsystem CSRs.IO requests are routed to this bus by means of the DW AMBA 3 AXIInterconnect. In case if an attempted APB transaction stays with noresponse for a pre-defined time an interrupt occurs and the bus getsfreed for a next operation. This driver provides the interrupt handlerto detect the erroneous address, prints an error message about theaddress fault, updates an errors counter. The counter and the APB-busoperations timeout can be accessed via corresponding sysfs nodes.A dedicated sysfs-node can be also used to artificially cause thebus errors described above.[arnd: fix build warnings for missing includes and wrong return types]Link: https://lore.kernel.org/r/20200526125928.17096-6-Sergey.Semin@baikalelectronics.ruSigned-off-by: Serge Semin Cc: Alexey Malahov Cc: Paul Burton Cc: Olof Johansson Cc: Rob Herring Cc: linux-mips@vger.kernel.orgCc: soc@kernel.orgCc: devicetree@vger.kernel.orgReported-by: kbuild test robot Reported-by: kbuild test robot Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/bus/Kconfig

bus: Add Baikal-T1 AXI-bus driverAXI3-bus is the main communication bus connecting all high-speedperipheral IP-cores with RAM controller and MIPS P5600 cores on Baikal-T1SoC. Bus traffic arbitration is done by means of DW AMBA 3 AXIInterconnect (so called AXI Main Interconnect) routing IO requests fromone SoC block to another. This driver provides a way to detect any busprotocol errors and device not responding situations by means of anembedded on top of the interconnect errors handler block (EHB). AXIInterconnect QoS arbitration tuning is currently unsupported.The bus doesn't provide a way to detect the interconnected devices,so they are supposed to be statically defined like by means of thesimple-bus sub-nodes.[arnd: fix build warnings for missing includes and wrong return types]Link: https://lore.kernel.org/r/20200526125928.17096-5-Sergey.Semin@baikalelectronics.ruSigned-off-by: Serge Semin Cc: Alexey Malahov Cc: Paul Burton Cc: Olof Johansson Cc: Rob Herring Cc: linux-mips@vger.kernel.orgCc: soc@kernel.orgCc: devicetree@vger.kernel.orgReported-by: kbuild test robot Reported-by: kbuild test robot Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/bus/Kconfig
