Subject: [PATCH 1/3] ARM: at91: pm: fix .uhp_udp_mask specification for current SoCs
Date: Wed, 27 Aug 2025 16:54:25 +0200 [thread overview]
Message-ID: <20250827145427.46819-2-nicolas.ferre@microchip.com> (raw)
In-Reply-To: <20250827145427.46819-1-nicolas.ferre@microchip.com>
From: Nicolas Ferre <nicolas.ferre@microchip.com>
All SoCs using this structure field .uhp_udp_mask in configuration
index 4 don't have the bit 7 specified: sam9x60 nor sam9x75.
Remove this bit from the mask definition to match register layout.
This mask is used in function at91_pm_verify_clocks().
