It manages many of the boundary signals from the MACB IP This patchset controls the tx_clk input signal to the MACB IP. It switches between the local TX clock (125MHz) and PHY TX clocks. This is necessary to toggle between 1Gb and 100/10Mb speeds. Future patches may add support for monitoring or controlling other IP boundary signals. This patchset is mostly based on work done by Wesley Terpstra This patchset is based on Linux v5.2-rc1 and tested on HiFive Unleashed board with additional board related patches needed for testing can be found at dev/yashs/ethernet branch of: https://github.com/yashshah7/riscv-linux.git Change History: V2: - Change compatible string from "cdns,fu540-macb" to "sifive,fu540-macb" - Add "MACB_SIFIVE_FU540" in Kconfig to support SiFive FU540 in macb driver. This is needed because on FU540, the macb driver depends on SiFive GPIO driver. - Avoid writing the result of a comparison to a register. - Fix the issue of probe fail on reloading the module reported by: Andreas Schwab Yash Shah (2): macb: bindings doc: add sifive fu540-c000 binding macb: Add support for SiFive FU540-C000 Documentation/devicetree/bindings/net/macb.txt | 3 + drivers/net/ethernet/cadence/Kconfig | 6 ++ drivers/net/ethernet/cadence/macb_main.c | 129 +++++++++++++++++++++++++ 3 files changed, 138 insertions(+) -- 1.9.1
