* drivers: soc: atmel: add per soc id and version match masksClaudiu Beznea2021-01-262-66/+140
| | | | | | | | | | | | 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.

* drivers: soc: atmel: add null entry at the end of at91_soc_allowed_list[]Claudiu Beznea2021-01-261-1/+2
| | | | | | | | | | | | | | 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.

* drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCsSudeep Holla2020-12-281-0/+12
| | | | | | | | | | | | | | | Since at91_soc_init is called unconditionally from atmel_soc_device_init, we get the following warning on all non AT91 SoCs: " AT91: Could not find identification node" Fix the same by filtering with allowed AT91 SoC list.
