[PATCH v2 1/5] mfd:rtsx: Read vendor setting from config space

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

 



From: Wei WANG <wei_wang@xxxxxxxxxxxxxx>

Normally OEMs will set vendor setting to the config space of Realtek
card reader in BIOS stage. This patch reads the setting at the first,
and configure the internal registers according to it, to improve card
reader's compatibility condition.
