Subject: [PATCH AUTOSEL 4.4 08/32] mmc: sdhci-pci-o2micro: Add quirk for O2 Micro dev 0x8620 rev 0x01
Date: Wed, 31 Oct 2018 19:11:13 -0400 [thread overview]
Message-ID: <20181031231137.29429-8-sashal@kernel.org> (raw)
In-Reply-To: <20181031231137.29429-1-sashal@kernel.org>
From: Yu Zhao <yuzhao@google.com>
[ Upstream commit 5169894982bb67486d93cc1e10151712bb86bcb6 ]
This device reports SDHCI_CLOCK_INT_STABLE even though it's not
ready to take SDHCI_CLOCK_CARD_EN. The symptom is that reading
SDHCI_CLOCK_CONTROL after enabling the clock shows absence of the
bit from the register (e.g. expecting 0x0000fa07 = 0x0000fa03 |
SDHCI_CLOCK_CARD_EN but only observed the first operand).
mmc1: Timeout waiting for hardware cmd interrupt.

mmc1: sdhci: ============================================
The problem happens during wakeup from S3. Adding a delay quirk
after power up reliably fixes the problem.
