Subject: [PATCH v3 0/2] Remove HS400 support from common
Date: Mon, 8 Sep 2025 18:52:05 -0500 [thread overview]
Message-ID: <20250908235207.473628-1-jm@ti.com> (raw)
Since eMMC HS400 has been descoped for j722s due to errata i2478 [0]
and is supported by default for AM62Px device, remove sdhci0 node from
common-main.dtsi and include instead only for AM62Px in am62p-main.dtsi.
Also, update the STRB value for am62p eMMC sdhci0 node.
Tested on am62p SK board.
