Subject: [PATCH RFC net-next v6 00/15] Add support for Synopsis DWMAC IP on
NXP Automotive SoCs S32G2xx/S32G3xx/S32R45
The SoC series S32G2xx and S32G3xx feature one DWMAC instance,
the SoC S32R45 has two instances. The devices can use RGMII/RMII/MII
interface over Pinctrl device or the output can be routed
to the embedded SerDes for SGMII connectivity.
The provided stmmac glue code implements only basic functionality,
interface support is restricted to RGMII only. More, including
SGMII/SerDes support will come later.
This patchset adds stmmac glue driver based on downstream NXP git [0].
[0] https://github.com/nxp-auto-linux/linux
v6:
- removed dead code in dwmac-intel-plat.c
- yaml: fix indention
- validate interface mode in probe
- dropped patch#16 to fit in max 15 patches in series
- Link to v5: https://lore.kernel.org/r/20241119-upstream_s32cc_gmac-v5-0-7dcc90fcffef@oss.nxp.com
v5:
- yaml: refactored compatible string to use fallback
- yaml: fix indention in example
- fix xmas tree formating in local variable declarations
- removed lazy rx clk setup
- drop PTP clock reading patch and replace it with stmmac_platform fix
- Link to v4: https://lore.kernel.org/r/20241028-upstream_s32cc_gmac-v4-0-03618f10e3e2@oss.nxp.com
v4:
- fixed empty commit messages for rgmi_clock() helper patches
- fixed yaml path in MAINTAINERS
- switched to platform_driver::remove() as suggested Uwe
- yaml: returned back all compatibility sting values
- added better commit description for rgmii_clock() helper
- Link to v3: https://lore.kernel.org/r/20241013-upstream_s32cc_gmac-v3-0-d84b5a67b930@oss.nxp.com
v3:
- switched to b4 WoW to overcome threading issue with b4
- extracted the hunk with the typo fix from v2 patch#1 to separate patch
as Jacob suggested
- removed dead code for RMII/MII support, which will be added alter
- used new rgmii_clock() helper in other stmmac:dwmac glue drivers
- yaml: compatible strings compressed to simple one "nxp,s32-dwmac",
removed duplicated required properties, already defined in snps,dwmac,
fixed example
v2:
- send to wider audience as first version missed many maintainers
- created rgmi_clk() helper as Russell suggested (see patch#4)
- address Andrew's, Russell's, Serge's and Simon's comments
