No need to hold pdev link when only dev is needed.
This allows to simplify a bunch of cpsw->pdev->dev now and farther.

Since the watermark calculations for Skylake are still broken, we're apt

Now that we can hook into update_crtcs and control the order in which we

Timeouts can be errors, but timeouts are also usually normal behavior
and happen a lot. Since the kernel already lets us know when we're
suppressing messages due to rate limiting, rate limit timeout errors so
we don't make too much noise in the kernel log.

As second net dev is created only in case of dual_emac mode, port
number can be figured out in simpler way. Also no need to pass
redundant ndev struct.

No. You already sent a *different* copy of all of these except for the

Are there any more functions to consider for such a source code searc
The napi structs are common for both net devices in dual_emac
mode, In order to not hold duplicate links to them, move to
cpsw_common.

While poll handlers there is no possibility to figure out
which network device is handling packets, as cpdma channels
are common for both network devices in dual_emac mode. Currently,
the messages are printed only for one device, in fact, there is two.
So, better to print integrated num_tx value fo

The irq data are common per net device. So no need to hold these
data per net dev, move it under cpsw_common. Also delete irq_num
var, as after optimization it's not needed. Correct number of
irqs to 2, as anyway, driver is using only 2, at least for now.

There is no need to hold link to clk, it's used only once

top(1) opens the following files for every PID:
/proc/*/stat
/proc/*/statm
/proc/*/status
This patch switches /proc/*/status away from seq_printf().
The result is 13.5% speedup.
Benchmark is open("/proc/self/status")+read+close 1.000.000 million times.
There is no need in priv here.
