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
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
