Hi Saeed,
mlx5_get_vector_affinity used to call pci_irq_get_affinity and after
reverting the patch that sets the device affinity via PCI_IRQ_AFFINITY
API, calling pci_irq_get_affinity becomes useless and it breaks RDMA
mlx5 users. To fix this, this patch provides an alternative way to

The dual-port Ether configurations always have a shared TSU to e.g. pass
the packets between those ports. With the TSU init. code gathered under
the single *if*, we now can only get the port # from 'platform_device::id'
only when we actually need it (and not recalculate it each time)...

Hello!
Here's a set of 2 patches against DaveM's 'net-next.git' repo. With those,
I'm somewhat simplifying the TSU init code in the driver probe() method...
[1/2] sh_eth: gather all TSU init code in one place
[2/2] sh_eth: get Ether port # only when needed
MBR, Sergei
The sh_eth_cpu_data::chip_reset() method always resets using ARSTR and
this register is always located at the start of the TSU register region.
Therefore, we can only call this method if we know TSU is there and thus
simplify the probing code a bit...

On Meson8b the only valid input clock is MPLL2. The bootloader
configures that to run at 52394Hz which cannot be divided evenly
down to 125MHz using the m250_div clock. Currently the common clock
framework chooses a m250_div of 2 - with the internal fixed
"divide by 10" this results in a RGMII
Neither the m25_div_clk nor the m250_div_clk or m250_mux_clk are used in
RMII mode. The m25_div_clk output is routed to the RGMII PHY's "RGMII
clock".
This means that we don't need to configure the clocks in RMII mode. The
driver however did this - with no effect since the clocks are not routed

Instead of using a custom buffer, snprintf() and devm_kstrdup() we can
