Subject: [PATCH 3/4] mmc: f-sdh30: Add quirks for broken timeout clock capability
Date: Tue, 8 Nov 2022 17:25:32 +0900 [thread overview]
Message-ID: <20221108082533.21384-4-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <20221108082533.21384-1-hayashi.kunihiko@socionext.com>
There is a case where the timeout clock is not supplied to the capability.
Add a quirk for that.
