Subject: [U-Boot] [U-Boot,3/3] rockchip: sdhci: support 8bit bus-width
Date: Wed, 28 Mar 2018 23:47:44 +0200	[thread overview]

> The Rockchip-specific SDHCI wrapper does not process the 'bus-width'
> property in the SDHCI node. Consequently, the bus is always kept in
> 4bit mode, even if 8bit wide operation is available, supported and
> requested in the DTS.
> 
> This change adds processing of the 'bus-width' property and sets the
> host capability flag for an 8bit wide bus, if set to 8. As the logic
> in sdhci.c does not support clearing the 4bit capability, we assume
> that 4bit operation is always supported.
