The DWMAC core appears to have a clock input for the transmit section called clk_tx_i which requires this rate. This series moves the code which sets this clock into the core stmmac code. Patch 1 adds a hook that platforms can use to configure the clock rate. Patch 2 adds a generic implementation. Patches 3 through 7 convert the easy-to-convert platforms to use this new infrastructure. .../ethernet/stmicro/stmmac/dwmac-dwc-qos-eth.c | 10 +---- drivers/net/ethernet/stmicro/stmmac/dwmac-imx.c | 5 ++- .../net/ethernet/stmicro/stmmac/dwmac-intel-plat.c | 24 ++---------- drivers/net/ethernet/stmicro/stmmac/dwmac-s32.c | 22 ++--------- .../net/ethernet/stmicro/stmmac/dwmac-starfive.c | 26 ++----------- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 2 + drivers/net/ethernet/stmicro/stmmac/stmmac_main.c | 43 ++++++++++++++++++++++ include/linux/stmmac.h | 4 ++ 8 files changed, 65 insertions(+), 71 deletions(-)
