net: phy: remove redundant "depends on" lines

2022-12-09T04:01:21+00:00

Delete a few lines of "depends on PHYLIB" since they are inside
an "if PHYLIB / endif # PHYLIB" block, i.e., they are redundant
and the other 50+ drivers there don't use "depends on PHYLIB"
since it is not needed.

net: phy: add Motorcomm YT8531S phy id.

2022-11-25T07:54:52+00:00

We added patch for motorcomm.c to support YT8531S. This patch has
been tested on AM335x platform which has one YT8531S interface
card and passed all test cases.
The tested cases indluding: YT8531S UTP function with support of
10M/100M/1000M; YT8531S Fiber function with support of 100M/1000M;
and YT8531S Combo function that supports auto detection of media type.

Since most functions of YT8531S are similar to YT8521 and we reuse some
codes for YT8521 in the patch file.

net: phy: Add driver for Motorcomm yt8521 gigabit ethernet phy

2022-10-31T10:51:54+00:00

Add a driver for the motorcomm yt8521 gigabit ethernet phy. We have verified
 the driver on StarFive VisionFive development board, which is developed by
 Shanghai StarFive Technology Co., Ltd.. On the board, yt8521 gigabit ethernet
 phy works in utp mode, RGMII interface, supports 1000M/100M/10M speeds, and
 wol(magic package).

net: phy: Kconfig: micrel_phy: fix dependency issue

2022-03-15T11:28:56+00:00

When building driver CONFIG_MICREL_PHY the follow error shows up:

aarch64-linux-gnu-ld: drivers/net/phy/micrel.o: in function `lan8814_ts_info':

Rework Kconfig for MICREL_PHY to depend on 'PTP_1588_CLOCK_OPTIONAL'.
Arnd describes in a good way why its needed to add this depends in patch
e5f31552674e ("ethernet: fix PTP_1588_CLOCK dependencies").

ethernet: fix PTP_1588_CLOCK dependencies

2021-08-14T00:49:05+00:00

The 'imply' keyword does not do what most people think it does, it only
politely asks Kconfig to turn on another symbol, but does not prevent
it from being disabled manually or built as a loadable module when the
user is built-in. In the ICE driver, the latter now causes a link failure:

aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl':
ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config'

aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild':

This is a recurring problem in many drivers, and we have discussed
it several times befores, without reaching a consensus. I'm providing
a link to the previous email thread for reference, which discusses
some related problems.

To solve the dependency issue better than the 'imply' keyword, introduce a
separate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any driver
can depend on if it is able to use PTP support when available, but works
fine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers are
then prevented from being built-in, the same way as with a 'depends on
PTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick,
but that can be rather confusing when you first see it.

Since this should cover the dependencies correctly, the IS_REACHABLE()
hack in the header is no longer needed now, and can be turned back
into a normal IS_ENABLED() check. Any driver that gets the dependency
wrong will now cause a link time failure rather than being unable to use
PTP support when that is in a loadable module.

However, the two recently added ptp_get_vclocks_index() and
ptp_convert_timestamp() interfaces are only called from builtin code with
ethtool and socket timestamps, so keep the current behavior by stubbing
those out completely when PTP is in a loadable module. This should be
addressed properly in a follow-up.

As Richard suggested, we may want to actually turn PTP support into a
'bool' option later on, preventing it from being a loadable module
altogether, which would be one way to solve the problem with the ethtool
interface.
