Subject: [PATCH v3] arm64: dts: ti: k3-j721e-main: Remove ti,strobe-sel property
Date: Fri, 3 Feb 2023 13:07:24 +0530 [thread overview]
Message-ID: <20230203073724.29529-1-b-kapoor@ti.com> (raw)
According to latest errata of J721e [1], (i2024) 'MMCSD: Peripherals
Do Not Support HS400' which applies to MMCSD0 subsystem. Speed modes
supported has been already updated in commit eb8f6194e807 ("arm64: dts: ti: k3-j721e-main: Update the speed modes supported and their itap delay values for MMCSD subsystems")
but it missed dropping 'ti,strobe-sel' property which is only required
by HS400 speed mode.
Thus, drop 'ti,strobe-sel' property from kernel dtsi for J721e SoC.
