[v6,00/10] net: eth: altera: tse: Add PTP and mSGDMA prefetcher

From: Joyce Ooi <joyce.ooi@intel.com>

This patch series cleans up the Altera TSE driver and adds support
for the newer msgdma prefetcher as well as ptp support when using
the msgdma prefetcher.

v2: Rename altera_ptp to intel_fpga_tod, modify msgdma and sgdma tx_buffer
    functions to be of type netdev_tx_t, and minor suggested edits
v3: Modify tx_buffer to stop queue before returning NETDEV_TX_BUSY
v4: Fix build warnings
v5: Rename 'ptp_enable' variable to 'has_ptp' and initialize hardware clock
    to 0 in intel_fpga_tod, and make minor suggested changes
v6: Fix build warning and remove return error to allow PHY with
    timestamping support to pass through ioctl

Dalon Westergreen (10):
  net: eth: altera: tse_start_xmit ignores tx_buffer call response
