[PATCH V4 00/13] net: smc911x: Convert to DM
Perform DM conversion of the SMC911x driver.
Note that the DT compatible is set only for 9115 , so this might need to be changed.
Marek Vasut (13): net: smc911x: Remove pkt_data_{push,pull} net: smc911x: Replace malloc()+memset() with calloc() net: smc911x: Rename smc911x_rx() to smc911x_recv() net: smc911x: Invert the logic in smc911x_miiphy_{read,write}() net: smc911x: Fix potential memleak() in init fail path net: smc911x: Pull MII registration into separate function net: smc911x: Inline all functions from header file net: smc911x: Drop weak alias from 32bit accessors net: smc911x: Convert IO accessors to {read,write}{w,l}() net: smc911x: Pass around driver private data net: smc911x: Clean up the status handling in smc911x_recv() net: smc911x: Split non-DM specific bits from common code net: smc911x: Add DM support

These functions are never used and are likely a pre-DM remnant from times long past, just remove them.

Replace combination of malloc()+memset() with calloc() as the behavior is exactly the same and the amount of code is reduced.

Fix memleak in the init fail path, where if allocation or registration of MDIO bus fails, then ethernet interface is not unregistered and the private data are not freed, yet the probe function reports a failure.

Pull the MII interface registration into separate function to avoid the ifdeffery in smc911x_initialize(). Moreover, adjust the fail path such that we use goto labels.

Inline all the functions from the header file, as they are not used outside of the driver or the standalone EEPROM example.
Note that this does introduce considerable amount of duplication in the standalone EEPROM example, however that one has to be rewritten anyway, roughly such that the SMC911x driver would expose DM EEPROM interface and the standalone example would use that.

These accessors are not overridden by any board, and even if they were, this is something which should be handled via DM now, so remove the weak alias option. Moreover, drop the inline keyword, as the compiler can decide better.

Convert the IO accessors to standard ones instead of using volatile void pointers, as those do not cover all the bus access details.

Introduce a private data structure for this driver with embedded struct eth_device and pass it around. This prepares the driver to work with both DM and non-DM systems.

Once your patch has been accepted, I will convert the boards that I maintain. The way you set it up shows they work using the non-DM and DM options. I have verified it on mine using both, but I don't have the other hardware to verify the functionality, but I'll try to CC a variety of omap people that I know of so they are aware.

Ping? It's been nearly a year, and I wrongly assumed this had been accepted.
I noticed this is still in limbo and my board is throwing a warning because DM_ETH is not enabled and it's at rish of being removed. I have an additional patch to prevent that, but until this patch is accepted, mine will not build.

Just wondering when we can expect these to get merged? I have a patch pending this so I can make a build warning go away about meeting requirements for 2020.07, but without this patch, it causes build errors.
I am tempted to just pick all the network patches via u-boot-sh, since I have like 40 outstanding patches for various ethernet drivers myself and I didn't hear from Joe for about a month now.
Ping? It's been nearly a year, and I wrongly assumed this had been accepted.
I noticed this is still in limbo and my board is throwing a warning because DM_ETH is not enabled and it's at rish of being removed. I have an additional patch to prevent that, but until this patch is accepted, mine will not build.

net: smc911x: Add DM support
Add support for U-Boot DM and DT probing. Furthermore, build the SMC911x standalone EEPROM example only for the non-DM case, as it is not converted yet.

Cool. Sorry for the noise. For some reason that driver doesn't appear to build with DM_ETH enabled. I'll investigate further

Sorry for the noise. I was on 2020.04 rc branch and not 2021.04
That was my mistake. (I am embarrassed)
