From: Naina Mehta Date: Fri, 21 Nov 2025 06:14:11 +0000 (+0530) Subject: watchdog: sbsa: Update the W_IIDR Implementer bit mask to 0xFFF X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a1a548c5eca62716c118134a8a1988277e8c5e96;p=thirdparty%2Flinux.git watchdog: sbsa: Update the W_IIDR Implementer bit mask to 0xFFF The implementer mask defined in the driver [1] captures bits 0-10, whereas section C.4.2 of BSA specification [2] indicates that bits 0-11 of the W_IIDR register represent the implementer JEP106 code. Update the SBSA_GWDT_IMPL_MASK corresponding to bits 0-11, while at it update SBSA_GWDT_VERSION_MASK mask to use GENMASK. [1] #define SBSA_GWDT_IMPL_MASK 0x7FF [2] Implementer, bits [11:0] Contains the JEP106 code of the company that implemented the Generic Watchdog: Bits[11:8] The JEP106 continuation code of the implementer. Bit[7] Always 0 Bits [6:0] The JEP106 identity code of the implementer.
