2021-01-26drivers: soc: atmel: add per soc id and version match masksClaudiu Beznea2-66/+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.

2021-01-26drivers: soc: atmel: add null entry at the end of at91_soc_allowed_list[]Claudiu Beznea1-1/+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.

2020-12-28drivers: soc: atmel: Avoid calling at91_soc_init on non AT91 SoCsSudeep Holla1-0/+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.
