2024-12-08soc: atmel: fix device_node release in atmel_soc_device_init()Javier Carrasco
A device_node acquired via of_find_node_by_path() requires explicit calls to of_node_put() when it is no longer needed to avoid leaking the resource. Instead of adding the missing calls to of_node_put() in all execution paths, use the cleanup attribute for 'np' by means of the __free() macro, which automatically calls of_node_put() when the variable goes out of scope.

2021-01-26drivers: soc: atmel: add per soc id and version match masksClaudiu Beznea
SAMA7G5 has different masks for chip ID and chip version on CIDR register compared to previous AT91 SoCs. For this the commit adapts the code for SAMA7G5 addition by introducing 2 new members in struct at91_soc and fill them properly and also preparing the parsing of proper DT binding.

2021-01-26drivers: soc: atmel: add null entry at the end of at91_soc_allowed_list[]Claudiu Beznea
of_match_node() calls __of_match_node() which loops though the entries of matches array. It stops when condition: (matches->name[0] || matches->type[0] || matches->compatible[0]) is false. Thus, add a null entry at the end of at91_soc_allowed_list[] array.
