[PATCH] arm64: dts: ti: k3-j721e-main: Remove ti,strobe-sel property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



According to latest errata of J721e [1], HS400 mode is not supported
in MMCSD0 subsystem (i2024) .  Speed modes supported has been already
updated in PATCH eb8f6194e807. 'ti,strobe-sel' property is only
required by HS400 speed mode and thus needs to be removed from kernel
dtsi for J721e soc.

'ti,strobe-sel' is read in sdhci_am654.c line 733 and gets stored in
sdhci_am654->strb_sel. This sdhci_am654->strb_sel is used at only one
place in sdhci_am654.c line 291 which will only get used if HS400
is enabled.

Thus, drop 'ti,strobe-sel' property from kernel dtsi for J721e soc.
