net: mdio-gpio: Add support for separate MDI and MDO gpio pins

2014-04-16T19:09:51+00:00

This is for a system with fixed assignments of input and output pins
(various variants of Kontron COMe).

net: mdio-gpio: Add support for active low gpio pins

2014-04-16T19:09:51+00:00

Some systems using mdio-gpio may use active-low gpio pins
(eg with inverters or FETs connected to all or some of the
gpio pins).

This simplifies error path and deinit/removal functions.

net: Micrel KSZ8864RMN 4-port managed switch support

2014-04-03T20:15:29+00:00

This patch adds support for the Micrel KSZ8864RMN switch to the spi_ks8995
driver. The KSZ8864RMN switch has a wider 256-byte register space.

net: ptp: move PTP classifier in its own file

2014-04-01T20:43:18+00:00

This commit fixes a build error reported by Fengguang, that is
triggered when CONFIG_NETWORK_PHY_TIMESTAMPING is not set:

  ERROR: "ptp_classify_raw" [drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe.ko] undefined!

The fix is to introduce its own file for the PTP BPF classifier,
so that PTP_1588_CLOCK and/or NETWORK_PHY_TIMESTAMPING can select
it independently from each other. IXP4xx driver on ARM needs to
select it as well since it does not seem to select PTP_1588_CLOCK
or similar that would pull it in automatically.

This also allows for hiding all of the internals of the BPF PTP
program inside that file, and only exporting relevant API bits
to drivers.

This patch also adds a kdoc documentation of ptp_classify_raw()
API to make it clear that it can return PTP_CLASS_* defines. Also,
the BPF program has been translated into bpf_asm code, so that it
can be more easily read and altered (extensively documented in [1]).

In the kernel tree under tools/net/ we have bpf_asm and bpf_dbg
tools, so the commented program can simply be translated via
`./bpf_asm -c prog` where prog is a file that contains the
commented code. This makes it easily readable/verifiable and when
there's a need to change something, jump offsets etc do not need
to be replaced manually which can be very error prone. Instead,
a newly translated version via bpf_asm can simply replace the old
code. I have checked opcode diffs before/after and it's the very
same filter.

sun4i_mdio_reset() does nothing useful and is optional for the MDIO bus
code, so let's just remove it.

net: phy: bcm7xxx: properly clear AFE_RX_LP_COUNTER

2014-03-26T20:19:24+00:00

The AFE_RX_LP_COUNTER kept the last 3 bits set, which would not properly
clear the EEE LPI mode errors bits. Make sure that those bits are set to
0 to ensure the PHY timing is always good even during EEE wake-up.

net: phy: bcm7xxx: fix spurious MDIO failures during workaround

2014-03-26T20:19:24+00:00

Writing first to the AFE registers, and then the VCO, RCAL, RC_CAL
registers turned out to unveil some spurious MDIO read/write failures
which would make the workaround partially applied. The fix is to write
first to the VCO, RCAL, RC_CAL registers, and then write to the AFE
registers.
