This register is prsent on the r8a7790 SoC. Signed-off-by: Simon Horman <horms+renesas@verge.net.au> -- v4 * Update changelog. v3 * The subsequent patch to add r8a7790 support has been reworked. To reflect this do not add set the rmmimode bit of any currently available struct sh_eth_cpu_data. A new one will be added for r8a7790 and the bit will be set when it is added. v2 * Split from patch to add r8a7790 support to driver (ifdef nastiness) * As suggested by Sergei Shtylyov - Add a field to struct sh_eth_cpu_data to indicate if the rmiimode register is present. This replaces an extremely ugly ifdef. --- drivers/net/ethernet/renesas/sh_eth.c | 4 ++++ drivers/net/ethernet/renesas/sh_eth.h | 2 ++ 2 files changed, 6 insertions(+)
