Commit 0cd8f9cc06 ("drivers: net: cpsw:
enable promiscuous mode support")
Enable promiscuous mode support for CPSW.
Introduced a crash on an am335x based board (similiar to am335x-evm).
Reason is buggy end condition in for loop in cpsw_set_promiscious()
for (i = 0; i <= priv->data.slaves; i++)
should be
for (i = 0; i < priv->data.slaves; i++)
Fix this ...

During checking the interrupts with "cat /proc/interrupts", it is showing
device name as (null), this change was done with commit id aa1a15e2d where
request_irq is changed to devm_request_irq also changing the irq name from
platform device name to net device name, but the net device is not
registered at this point with the network frame work, so devm_request_irq
is called with device name as NULL, by which it is showed as "(null)" in
"cat /proc/interrupts". So this patch changes back irq name to platform
device name itself in devm_request_irq so that the device name shows as
below.

When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.
Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.
Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e0076a (net: davinci_emac: switch to

cpsw_hwtstamp_ioctl() should validate all fields of hwtstamp_config,

sets the TX configuration before validating the rx_filter field
or that the hardware supports timestamping.
Also correct the error code for hardware versions that don't
support timestamping. ENOTSUPP is used by the NFS implementation
and is not part of userland API; we want EOPNOTSUPP (which glibc
also calls ENOTSUP, with one 'P').

When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't,
emac_dev_mcast_set should only enable RX of multicasts and reset
MACHASH registers.
It does this, but afterwards it either sets up multicast MACs
filtering or disables RX of multicasts and resets MACHASH registers
again, rendering IFF_ALLMULTI flag useless.
This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and
disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set.

The cpsw currently lacks code to properly set up the hardware interface
mode on AM33xx. Other platforms might be equally affected.
Usually, the bootloader will configure the control module register, so
probably that's why such support wasn't needed in the past. In suspend
mode though, this register is modified, and so it needs reprogramming
after resume.
This patch adds a new driver in which hardware interface can configure
correct register bits when the slave is opened.
The AM33xx also has a bit for each slave to configure the RMII reference
clock direction. Setting it is now supported by a per-slave DT property.
This code path introducted by this patch is currently exclusive for
am33xx and same can be extened to various platforms via the DT compatibility
property.
