Subject: [U-Boot] [PATCH v2 0/4] mmc: sdhci: Add support for frequency constrained peripheral interfaces
Date: Fri, 25 Nov 2016 14:59:50 +0100	[thread overview]
Message-ID: <1480082395-14750-1-git-send-email-stefan.herbrechtsmeier@weidmueller.de> (raw)

The sdhci controller assumes that the base clock frequency is fully
supported by the peripheral and doesn't support hardware limitations.
Distinguish between base clock of the host controller and maximal
supported peripheral clock frequency of the peripheral interface.
This is needed for the zynq platform to support two sdhci ports with
different IO routings.

Changes in v2:
- Remove unused index from get uart clock function
- Remove unused index from get sdio clock function
- Introduce common get clock function
