[PATCH 1/2] scripts: remove CONFIG_IS_ENABLED and CONFIG_VAL in generated u_boot.cfg
by Patrick Delaunay 02 Dec '21

02 Dec '21

The two helpers macros CONFIG_IS_ENABLED and CONFIG_VAL are defined in include/linux/kconfig.h but they are not real configurations; they can be safely removed in the generated configuration file "u-boot.cfg".

[PATCH] net: eth-phy: Handle gpio_request_by_name() return value
by Marek Vasut 02 Dec '21

02 Dec '21

The gpio_request_by_name() returns zero in case of success, however the conditional return value check in gpio_request_by_name() checks only for (ret != -ENOENT) and if the condition is true, returns ret outright. This leads to a situation where successful gpio_request_by_name() return leads to immediate successful eth_phy_of_to_plat() return as well, and to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the PHY driver operates with valid reset GPIO, but with assert/deassert times set to default, which is 0, instead of the values from DT. This breaks PHY reset. Fix this by checking if return value is non-zero and then for this one single allowed non-zero return value, -ENOENT.

[PATCH] net: dwc_eth_qos: Enable clock in probe
by Marek Vasut 02 Dec '21

02 Dec '21

Enable DWC IP clock in driver probe, so the MII access is possible even outside of active network transfers. This is particularly useful when using 'mii' or 'mdio' commands to explore PHY state, neither of which works with DWMAC currently due to the disabled clock.
