Subject: [PATCH 04/18] PCI: Add PCI_EXP_SLTCAP_*_SHIFT macros
Date: Sun, 20 Feb 2022 20:33:32 +0100	[thread overview]
Message-ID: <20220220193346.23789-5-kabel@kernel.org> (raw)
In-Reply-To: <20220220193346.23789-1-kabel@kernel.org>

From: Pali Rohár <pali@kernel.org>

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