This patch set introduces a general way to correct the bits when they are read to accurately reflect the capabilties of the controller/board combo. The first patch creates sdhci-caps and sdhci-caps-mask dt properties that combined represent the correction to the sdhci caps register. The second patch uses the new dt properties to correct the caps from the register as they read during __sdhci_read_caps. Changes from RFC: * /s/registers/register * Moved sdhci dt properties into new documentation file sdhci.txt v2: * Fixed style issue, all branches of 'if' should have {} Zach Brown (2): mmc: sdhci: dt: Add device tree properties sdhci-caps and sdhci-caps-mask mmc: sdhci: Use sdhci-caps-mask and sdhci-caps to change the caps read during __sdhci_read_caps Documentation/devicetree/bindings/mmc/sdhci.txt | 14 ++++++++++++++ drivers/mmc/host/sdhci.c | 24 ++++++++++++++++++++++-- 2 files changed, 36 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/mmc/sdhci.txt -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
