On MMUs such as FSL where we can guarantee the entire linear mapping is
bolted, we don't need to worry about linear TLB misses. If on top of
that we do a full table walk, we get rid of all recursive TLB faults, and
can dispense with some state saving. This gains a few percent on

Hi,
On a custom P1022-based board I have SGMII PHY connected to eTSEC1.
PHY address is 0x1. Ethernet works fine in u-boot, but in linux
there's no link.
I have the following in my device tree:
mdio@24000 {
#address-cells = <1>;

The only reason to require a dma_ops struct is to see if it has
implemented set_dma_mask. If not we can fall back to setting the mask
directly.
This resolves an issue with how to sequence the setting of a DMA mask
for platform devices. Before we had an issue in that we have no way of
setting the
We have a long standing issues with platform devices not have a valid
dma_mask pointer. This hasn't been an issue to date as no platform
device has tried to set its dma_mask value to a non-default value.
