Subject: [PATCH 3/3] arm64: dts: meson-gx: Make mmc host controller interrupts level-sensitive
Date: Thu, 9 Feb 2023 21:11:47 +0100	[thread overview]
Message-ID: <76e042e0-a610-5ed5-209f-c4d7f879df44@gmail.com> (raw)
In-Reply-To: <8a99341b-8546-8f90-c9a5-087d927cac48@gmail.com>

The usage of edge-triggered interrupts lead to lost interrupts under load,
see [0]. This was confirmed to be fixed by using level-triggered
interrupts.
The report was about SDIO. However, as the host controller is the same
for SD and MMC, apply the change to all mmc controller instances.
