This patch series based on the suggestion of Scott Branden to implement bcm2835 support into sdhci-iproc [1]. These changes provide the following advantages: * no need to maintain a separate driver for bcm2835 * improve support and test coverage of bcm2835 mmc support * get the rid of SDHCI_CAPABILITIES hack in bcm2835_sdhci_readl * increase write performance by avoiding delays in write ops Patch 1 and 2 adopt two sdhci-bcm2835 fixes to sdhci-iproc. The third patch tries to specify as much quirks as possible in the bcm283x.dtsi as possible. Patch 4 and 5 are the actually changes for bcm2835 support.
