Subject: [PATCH net-next v4 0/3] riscv: sophgo: Add ethernet support for SG2044
Date: Sun,  9 Feb 2025 09:30:49 +0800	[thread overview]
Message-ID: <20250209013054.816580-1-inochiama@gmail.com> (raw)

The ethernet controller of SG2044 is Synopsys DesignWare IP with
custom clock. Add glue layer for it.

Changed from v3:
- https://lore.kernel.org/netdev/20241223005843.483805-1-inochiama@gmail.com/
1. rebase for 6.14.rc1
2. remove the dependency requirement as it was already merged
   into master.

Changed from RFC:
- https://lore.kernel.org/netdev/20241101014327.513732-1-inochiama@gmail.com/
1. patch 1: apply Krzysztof' tag

Changed from v2:
- https://lore.kernel.org/netdev/20241025011000.244350-1-inochiama@gmail.com/
1. patch 1: merge the first and the second bindings patch to show the all
            compatible change.
2. patch 2: use of_device_compatible_match helper function to perform check.
2. patch 3: remove unused include and sort the left.
3. patch 3: fix wrong variable usage in sophgo_dwmac_fix_mac_speed
4. patch 3: drop unused variable in the patch.

Changed from v1:
- https://lore.kernel.org/netdev/20241021103617.653386-1-inochiama@gmail.com/
1. patch 2: remove sophgo,syscon as this mac delay is resolved.
2. patch 2: apply all the properties unconditionally.
3. patch 4: remove sophgo,syscon code as this mac delay is resolved.
4. patch 4: use the helper function to compute rgmii clock.
5. patch 4: use remove instead of remove_new for the platform driver.
