net: macb: Fix incorrect write function name when MACB_ZYNQ is enabled.

2020-03-31T14:06:53+00:00

When MACB_ZYNQ is enabled there is compilation warnings
drivers/net/macb.c: In function ‘_macb_init’:
drivers/net/macb.h:675:33: error: ‘MACB_DMACFG’ undeclared (first use in this function);
 did you mean ‘MACB_MCF’?
  writel((value), (port)->regs + MACB_##reg)
                                 ^~~~~

It has been caused by changing macros name by commit below.

dma-mapping: move dma_map_(un)single() to

2020-02-19T13:27:30+00:00

The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.

Factor them out to , and make all drivers to
include  instead of .

If we need to differentiate them for some architectures, we can
move the generic definitions to .

Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

dma-mapping: fix the prototype of dma_unmap_single()

2020-02-19T13:27:30+00:00

dma_unmap_single() takes the dma address, not virtual address.

net: macb: Drop local cache flush

2020-01-25T17:04:36+00:00

Now that arch specific dma mapping APIs take care of cache
flush/invalidate, drop local cache flush operation.
While at that fix dma_unmap_single() call to match new prototype

net: macb: let miiphy_read/_write pass arbitrary addresses

2019-12-09T15:47:42+00:00

This allows passing arbitrary addresses through macb_miiphy_read and
macb_miiphy_write, therefore enabling the mii command to access
all mdio bus devices instead of only the defined phy.

net: macb: explicitly pass phy_adr to mdio read and write

2019-12-09T15:47:42+00:00

To support accessing arbitrary addresses the mii/mdio bus it is
necessary that the macb_mdio_read and macb_mdio_write functions
do not implicitly use the address of the connected phy.

The function signature is extended according to the Linux kernel
equivalent.

net: macb: Fix rx buffer cache handling

2019-09-04T16:37:19+00:00

With commit c6d07bf440bc ("net/macb: increase RX buffer size for GEM")
ethernet support does not work any more with d-cache enabled on the
AT91SAM. The reason is, that MACB_RX_BUFFER_SIZE was changed from 4096
to 128 but this change was not refected in the rx_buffer flush and
invalidate functions, as these also use this macro.

This patch now fixes this by calculating the rx buffer size correctly
again in those functions. With this change, ethernet works again
reliably on my AT91SAM board.
