On FU540, the management IP block is tightly coupled with the Cadence MACB IP block. 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 <wesley@sifive.com>
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 <schwab@suse.de>
