Subject: [PATCH v3 10/13] PCI: apple: Drop poll for CORE_RC_PHYIF_STAT_REFCLK
Date: Tue, 1 Apr 2025 10:17:10 +0100 [thread overview]
Message-ID: <20250401091713.2765724-11-maz@kernel.org> (raw)
In-Reply-To: <20250401091713.2765724-1-maz@kernel.org>
From: Hector Martin <marcan@marcan.st>
This is checking a core refclk in per-port setup which doesn't make a
lot of sense, and the bootloader needs to have gone through this anyway.
It doesn't work on T602x, so just drop it across the board.
