net: stmmac: tegra: Properly allocate clock bulk data

2023-07-29T15:59:51+00:00

The clock data is an array of struct clk_bulk_data, so make sure to
allocate enough memory.

net: stmmac: Apply redundant write work around on 4.xx too

2023-07-25T09:03:55+00:00

commit a3a57bf07de23fe1ff779e0fdf710aa581c3ff73 ("net: stmmac: work
around sporadic tx issue on link-up") worked around a problem with TX
sometimes not working after a link-up by avoiding a redundant write to
MAC_CTRL_REG (aka GMAC_CONFIG), since the IP appeared to have problems
with handling multiple writes to that register in some cases.

That commit however only added the work around to dwmac_lib.c (apart
from the common code in stmmac_main.c), but my systems with version
4.21a of the IP exhibit the same problem, so add the work around to
dwmac4_lib.c too.

Use the devres variant of stmmac_pltfr_probe() and finally drop the
remove() callback entirely.

net: stmmac: platform: provide devm_stmmac_pltfr_probe()

2023-06-24T22:36:00+00:00

Provide a devres variant of stmmac_pltfr_probe() which allows users to
skip calling stmmac_pltfr_remove() at driver detach.

net: stmmac: dwmac-qco-ethqos: use devm_stmmac_probe_config_dt()

2023-06-24T22:36:00+00:00

Significantly simplify the driver's probe() function by using the devres
variant of stmmac_probe_config_dt(). This allows to drop the goto jumps
entirely.

The remove_new() callback now needs to be switched to
stmmac_pltfr_remove_no_dt().

Add a variant of stmmac_pltfr_remove() that only frees resources
allocated by stmmac_pltfr_probe() and - unlike stmmac_pltfr_remove() -
does not call stmmac_remove_config_dt().

2023-06-24T22:35:59+00:00

Implement stmmac_pltfr_probe() which is the logical API counterpart
for stmmac_pltfr_remove(). It calls the platform's init() callback and
then probes the stmmac device.
