This patch series fixes a bug where of_gpio_named count relied upon a return value that was no longer returned from of_parse_phandle_with_args and adds the possibility for of_gpio_named_count to return error values.
In addition, for of_spi_register_master it fixes a bug, adds documentation, adds fetching of gpio flags and initializes gpio values to be consistent with return values from of_parse_phandle_with_args.
Tested on sparc. Build tested on x86, arm and ppc.
Andreas Larsson (6): of: Return -EEXIST from of_parse_phandle_with_args for holes in phandle list of: Return -ENXIO from of_parse_phandle_with_args for too large index and return errors from of_gpio_named_count of_spi: Initialize cs_gpios properly of_spi: Document cs_gpios and cs_gpio in kernel-doc of_spi: Add fetching of of_gpio flags to of_spi_register_master of_spi: Initialize cs_gpios and cs_gpio with -EEXIST
