qps615-dlkm: Add recipe for QPS615 PCIe Ethernet module
Add a new DLKM recipe that builds and installs the TC956X host driver for the QPS615 PCIe Ethernet bridge chip with Qualcomm platform support. The recipe includes additional patches for: - Qualcomm-specific platform driver for PHY reset, power management, and WoL IRQ configuration - Cross-compilation support via Yocto - MAC address reading from device tree NVMEM - Kernel 6.18 API compatibility fixes - Module auto-loading support Signed-off-by: Mohd Ayaan Anwar <mohd.anwar@oss.qualcomm.com>

Subject: [PATCH 01/12] net: ethernet: tc956x: Makefile: support cross-build
5+
via KERNEL_SRC
6+
7+
Replace the hardcoded 'all:' and 'clean:' targets with conventional
8+
'modules', 'modules_install', and 'clean' targets that delegate to
9+
$(MAKE) instead of bare make. Introduce KERNEL_SRC with a ?= default
10+
so that Yocto/OE and other cross-build environments can override the
11+
kernel build tree without editing the file, while native development
12+
builds continue to fall back to /lib/modules/$(uname -r)/build.

Subject: [PATCH 02/12] net: ethernet: tc956x: read MAC address from DT/NVMEM
5+
on platform
6+
7+
Attempt to read the MAC address from the device tree or NVMEM via
8+
of_get_mac_address() before falling back to parse_config_file().
9+
Return -EPROBE_DEFER immediately if the NVMEM provider is not yet
10+
available, so the driver is re-probed once the dependency is ready.
11+
This allows platform DTS nodes to supply the MAC address through the
12+
standard 'mac-address' / 'local-mac-address' properties or a linked
13+
NVMEM cell without requiring a config.ini file.

Subject: [PATCH 03/12] net: ethernet: tc956x: Replace phylink .validate with
5+
.mac_get_caps (kernel 6.7)
6+
7+
The phylink_mac_ops.validate callback was removed in kernel 6.7 in favour
8+
of mac_get_caps(). Guard the old tc956xmac_validate() function behind a
9+
LINUX_VERSION_CODE < 6.7.0 check and add the new tc956xmac_mac_get_caps()
10+
implementation in the #else branch.
11+
12+
Populate mac->link.caps in dwxgmac2_setup() and add the caps field to
13+
struct mac_link in common.h so that mac_get_caps() can return the
14+
supported MAC capabilities.
