In Documentation stmmac.txt there is possibility to fixed CSR Clock range selection with property clk_csr. This patch add the management of this property For example to use it, add in your ethernet node DT: clk_csr = <3>; Signed-off-by: Christophe Roullier <christophe.roullier@st.com> --- drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c | 3 +++ 1 file changed, 3 insertions(+)
