Subject: [PATCH 5/7] drivers: soc: atmel: add per soc id and version match masks
Date: Fri, 22 Jan 2021 14:21:35 +0200	[thread overview]
Message-ID: <1611318097-8970-6-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1611318097-8970-1-git-send-email-claudiu.beznea@microchip.com>

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.

Subject: [PATCH 5/7] drivers: soc: atmel: add per soc id and version match masks
Date: Fri, 22 Jan 2021 14:21:35 +0200	[thread overview]
Message-ID: <1611318097-8970-6-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1611318097-8970-1-git-send-email-claudiu.beznea@microchip.com>

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.
