Subject: [PATCH v3 4/5] arm64: dts: ti: k3-j721s2-main: Enable support for SDR104 speed mode
From: Bhavya Kapoor <b-kapoor@...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
