Subject: [PATCH 2/6] PCI: Add PCI_EXP_SLTCAP_*_SHIFT macros
Date: Tue, 22 Feb 2022 17:31:54 +0100	[thread overview]
Message-ID: <20220222163158.1666-3-pali@kernel.org> (raw)
In-Reply-To: <20220222163158.1666-1-pali@kernel.org>

These macros allows to easily compose and extract Slot Power Limit and
Physical Slot Number values from Slot Capability Register.
