Messages in this thread | | | From | Andreas Larsson <> | Subject | [PATCH v2 0/6] of, of_gpio, of_spi: Bugfix and improve of_parse_phandle_with_args, of_gpio_named_count and of_spi_register_master | Date | Tue, 29 Jan 2013 15:53:37 +0100 |

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 (excluding the changes to drivers gpio-fan, i2c-mux-gpio, matrix_keypad, mdio-mux-gpio, spi-mpc52xx, spi-oc-tiny, spi-ppc4xx, selftest). Compile tested on x86, arm and ppc (all changed source files, when appropriate for platform)
Changes since v1: - PATCH 2/6: Handle error return values from calls to of_gpio_count
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
