Subject: [PATCH 4/7] arm64: dts: ti: k3-j721s2-main: Enable support for SDR104 speed mode
Date: Thu, 11 Apr 2024 17:52:54 -0500 [thread overview]
Message-ID: <20240411225257.383889-5-jm@ti.com> (raw)
In-Reply-To: <20240411225257.383889-1-jm@ti.com>
From: Bhavya Kapoor <b-kapoor@ti.com>
According to TRM for J721S2, SDR104 speed mode is supported by the SoC
but its capabilities were masked in device tree. Remove sdhci-caps-mask
to enable support for SDR104 speed mode for SD card in J721S2 SoC.
[+] Refer to : section 12.3.6.1.1 MMCSD Features, in J721S2 TRM

Fixes: b8545f9d3a54 ("arm64: dts: ti: Add initial support for J721S2 SoC")
