net: ethernet: qualcomm: QCOM_PPE should depend on ARCH_QCOM

2025-09-01T19:53:38Z

The Qualcomm Technologies, Inc. Packet Process Engine (PPE) is only present on Qualcomm IPQ SoCs. Hence add a dependency on ARCH_QCOM, to prevent asking the user about this driver when configuring a kernel without Qualcomm platform support, Fixes: 353a0f1d5b27606b ("net: ethernet: qualcomm: Add PPE driver for IPQ9574 SoC") Signed-off-by: Geert Uytterhoeven Reviewed-by: Simon Horman Link: https://patch.msgid.link/eb7bd6e6ce27eb6d602a63184d9daa80127e32bd.1756466786.git.geert+renesas@glider.be Signed-off-by: Jakub Kicinski

net: ethernet: qualcomm: Add PPE driver for IPQ9574 SoC

2025-08-21T10:38:41Z

The PPE (Packet Process Engine) hardware block is available on Qualcomm IPQ SoC that support PPE architecture, such as IPQ9574. The PPE in IPQ9574 includes six integrated Ethernet MAC for 6 PPE ports, buffer management, queue management and scheduler functions. The MACs can connect with the external PHY or switch devices using the UNIPHY PCS block available in the SoC. The PPE also includes various packet processing offload capabilities such as L3 routing and L2 bridging, VLAN and tunnel processing offload. It also includes Ethernet DMA function for transferring packets between ARM cores and PPE Ethernet ports. This patch adds the base source files and Makefiles for the PPE driver such as platform driver registration, clock initialization, and PPE reset routines.

net: phy: remove Kconfig symbol MDIO_DEVRES

2025-05-15T02:12:19Z

MDIO_DEVRES is only set where PHYLIB/PHYLINK are set which select MDIO_DEVRES. So we can remove this symbol. Note: Due to circular module dependencies we can't simply make mdio_devres.c part of phylib.

net: ethernet: Add missing depends on MDIO_DEVRES

2023-04-13T03:38:48Z

A number of MDIO drivers make use of devm_mdiobus_alloc_size(). This is only available when CONFIG_MDIO_DEVRES is enabled. Add missing depends or selects, depending on if there are circular dependencies or not. This avoids linker errors, especially for randconfig builds.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

drivers: net: ethernet: qualcomm: rmnet: Initial implementation

2017-08-30T18:41:13Z

RmNet driver provides a transport agnostic MAP (multiplexing and aggregation protocol) support in embedded module. Module provides virtual network devices which can be attached to any IP-mode physical device. This will be used to provide all MAP functionality on future hardware in a single consistent location.
