Subject: [PATCH net 0/5] dwc_eth_qos: stability fixes and support for CMA

This series has bug fixes for the dwc_eth_qos ethernet driver.

Mainly two stability fixes for problems found by Rabin Vincent:
- Successive starts and stops of the interface would trigger a DMA reset timeout.
- A race condition in the TX DMA handling could trigger a netdev watchdog
 timeout.

The memory allocation was improved to support use of the CMA as DMA allocator
backend.

Lars Persson (2):
  dwc_eth_qos: release descriptors outside netif_tx_lock
  dwc_eth_qos: do phy_start before resetting hardware

Rabin Vincent (3):
  dwc_eth_qos: fix race condition in dwceqos_start_xmit
  dwc_eth_qos: use GFP_KERNEL in dma_alloc_coherent()
  dwc_eth_qos: use DWCEQOS_MSG_DEFAULT
