Subject: [PATCH v4 08/12] PCI: brcmstb: Don't conflate the reset rescal with phy ctrl
Date: Tue, 16 Jul 2024 17:31:23 -0400 [thread overview]
Message-ID: <20240716213131.6036-9-james.quinlan@broadcom.com> (raw)
In-Reply-To: <20240716213131.6036-1-james.quinlan@broadcom.com>

We've been assuming that if an SOC has a "rescal" reset controller that we
should automatically invoke brcm_phy_cntl(...). This will not be true in
future SOCs, so we create a bool "has_phy" and adjust the cfg_data
appropriately (we need to give 7216 its own cfg_data structure instead of
sharing one).
