This patch set aims to remove the init/exit callbacks from the
dwmac-sti driver and instead use standard PM callbacks. Doing this
will also allow us to cleanup the driver.
Eventually the init/exit callbacks will be deprecated and removed
from all drivers dwmac-* except for dwmac-generic. Drivers will be
refactored to use standard PM and remove callbacks.
Note that this patch set has only been test compiled and no functional
change is intended.

Since dwmac-sti is a DT only driver checking for OF node is not necessary.

Since sti_dwmac_parse_data() sets dwmac->clk to NULL if not clock was
provided in DT and NULL is a valid clock there is no need to check for
NULL before using this clock.

Implement PM callbacks and driver remove in the driver instead
of relying on the init/exit hooks in stmmac_platform. This gives
the driver more flexibility in how the code is organized.
Eventually the init/exit callbacks will be deprecated in favor
of the standard PM callbacks and driver remove function.

The sti_dwmac_init() function is called both from probe and resume.
Since DT properties doesn't change between suspend/resume cycles move
parsing of this parameter into sti_dwmac_parse_data() where it belongs.

Add clock error handling to probe and in the process move clock enabling
out of sti_dwmac_init() to make this easier.

Adding some more ST people.
Could anyone with a stih407 platform please give these patches a try?
The series can found at https://github.com/manabian/linux-lpc.git in
the net-sti-dwmac branch (based on net-next).
Alternatively they can also be picked from netdev's patchwork.
regards,
Joachim Eastwood

Just noticed that I am missing a 'static' here.
As this not critical for testing I'll resend the patch set after I
(hopefully) get some response from someone with the hw that can do a
test.

Hello Joachim
thx for this series, I will review them and test the changes
on my board asap ... I let you known.

Hello Joachim.
I have tested the patches on STiH390 with GMAC4 and the driver is ok.
So you can add my Acked-by/Tested-by in the V2.
I just ask you, when rename the sti_dwmac_init in sti_dwmac_set_phy_mode
to use another name: sti_dwmac_set_mode could be good, IMO.
In fact, this function is not strictly related to the PHY and the
system config registers could touch different MAC/MII settings.
Regards
Peppe

Thanks! I'll send a V2 later today or tomorrow.

Sure thing.
