misc: echo: Remove

2025-05-01T15:57:08Z

'echo' is a software echo canceller for telco use, however it's not used in the kernel at all. Remove it. It was moved from staging in 2014 by commit Fixes: 6e2055a9e56e ("staging: echo: move to drivers/misc/") Some discussion on lkml: https://lore.kernel.org/all/Z7tZhYET41DAoHVf@gallifrey/ with Arnd and Harald, led to the 'dahdi' package which is part of Asterisk: https://gitea.osmocom.org/retronetworking/dahdi-linux which can build with the 'echo' module, but is normally configured with out it. Dahdi is large, old, only lightly maintained and with a big API, so there's no hope now of ever merging it into the main kernel tree. Debian do package Dahdi, and in their package they actually include a copy of the 'echo' module rather than using the kernel from the upstream kernel. So even in the few cases where it is packaged and built, the kernel copy isn't used.

misc: add FPC202 dual port controller driver

2025-04-18T21:34:41Z

The TI FPC202 dual port controller serves as a low-speed signal aggregator for common port types such as SFP, QSFP, Mini-SAS HD, and others. It aggregates GPIO and I2C signals across two downstream ports, acting as both a GPIO controller and an I2C address translator for up to two logical devices per port.

cxl: Remove driver

2025-03-16T11:04:27Z

Remove the cxl driver that provides support for the IBM Coherent Accelerator Processor Interface. Revert or clean up associated code in arch/powerpc that is no longer necessary. cxl has received minimal maintenance for several years, and is not supported on the Power10 processor. We aren't aware of any users who are likely to be using recent kernels. Thanks to Mikey Neuling, Ian Munsie, Daniel Axtens, Frederic Barrat, Christophe Lombard, Philippe Bergheaud, Vaibhav Jain and Alastair D'Silva for their work on this driver over the years.

Pull char/misc/IIO/whatever driver subsystem updates from Greg KH: "Here is the 'big and hairy' char/misc/iio and other small driver subsystem updates for 6.13-rc1. Loads of things in here, and even a fun merge conflict! - rust misc driver bindings and other rust changes to make misc drivers actually possible. I think this is the tipping point, expect to see way more rust drivers going forward now that these bindings are present. Next merge window hopefully we will have pci and platform drivers working, which will fully enable almost all driver subsystems to start accepting (or at least getting) rust drivers. This is the end result of a lot of work from a lot of people, congrats to all of them for getting this far, you've proved many of us wrong in the best way possible, working code :) - IIO driver updates, too many to list individually, that subsystem keeps growing and growing... - Interconnect driver updates - nvmem driver updates - pwm driver updates - platform_driver::remove() fixups, loads of them - counter driver updates - misc driver updates (keba?) - binder driver updates and fixes - loads of other small char/misc/etc driver updates and additions, full details in the shortlog.

misc: Add support for LAN966x PCI device

2024-10-24T10:09:33Z

Add a PCI driver that handles the LAN966x PCI device using a device-tree overlay. This overlay is applied to the PCI device DT node and allows to describe components that are present in the device. The memory from the device-tree is remapped to the BAR memory thanks to "ranges" properties computed at runtime by the PCI core during the PCI enumeration. The PCI device itself acts as an interrupt controller and is used as the parent of the internal LAN966x interrupt controller to route the interrupts to the assigned PCI INTx interrupt.

rpmb: add Replay Protected Memory Block (RPMB) subsystem

2024-08-26T11:16:20Z

A number of storage technologies support a specialised hardware partition designed to be resistant to replay attacks. The underlying HW protocols differ but the operations are common. The RPMB partition cannot be accessed via standard block layer, but by a set of specific RPMB commands. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage. The initial aim of this patch is to provide a simple RPMB driver interface which can be accessed by the optee driver to facilitate early RPMB access to OP-TEE OS (secure OS) during the boot time. A TEE device driver can claim the RPMB interface, for example, via rpmb_interface_register() or rpmb_dev_find_device(). The RPMB driver provides a callback to route RPMB frames to the RPMB device accessible via rpmb_route_frames(). The detailed operation of implementing the access is left to the TEE device driver itself.
