a=openpgp; fpr=169DEB6C0BC3C46013D2C79F11A72EA01471D772 I'm working on removing the fields relevant only to gpio-mmio from struct gpio_chip. One of the bits that need addressing before we can do this is the removal of struct bgpio_pdata from the kernel. Fortunately there are only 3 users left treewide. This series adds support for parsing of generic device properties to gpio-mmio, converts all users to setting up software nodes containing relevant values in their property sets and removes struct bgpio_pdata. As for merging: it would be best for MFD/OMAP/s3c maintainers to ack the changes and let me route them through the GPIO tree. I can provide an immutable tag if needed. Obviously I was only able to build-test the changes so any actual verification is appreciated.
