2015-01-30pinctrl: hide PCONFDUMP in #ifdefArnd Bergmann
The zynq and qcom-spmi pinctrl drivers both use pin_config_item arrays to provide extra interfaces in debugfs. This structure and the PCONFDUMP macro are not defined if CONFIG_DEBUG_FS is turned off, so we get build errors like: pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: error: array type has incomplete element type static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = { ^ pinctrl/qcom/pinctrl-spmi-gpio.c:140:2: error: implicit declaration of function 'PCONFDUMP' [-Werror=implicit-function-declaration] PCONFDUMP(PMIC_GPIO_CONF_PULL_UP, "pull up strength", NULL, true), ^ pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: warning: 'pmic_conf_items' defined but not used [-Wunused-variable] static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = { Lacking any better idea to solve this nicely, this patch uses #ifdef to hide the structures, just like the pinctrl core does.

2015-01-30pinctrl: zynq: Fix usb0 pinsAndreas Färber
Fix usb0 pin 19 -> 29 (matching ethernet1 pins and manual). Pin 19 is used for ethernet0 on the Parallella board.

2015-01-14pinctrl: pinconf-generic: loose DT dependenceLinus Walleij
New pin controllers such as ACPI-based may also have custom properties to parse, and should be able to use generic pin config. Let's make the code compile on !OF systems and rename members a bit to underscore it is custom parameters and not necessarily DT parameters. This fixes a build regression for x86_64 on the zeroday kernel builds.

2015-01-11pinctrl: Add driver for ZynqSoren Brinkmann
This adds a pin-control driver for Zynq. Changes since v2: - driver-specific DT properties are passed to the core in two arrays, one for the actual DT parsing one for the debugfs representation. Issue a compiler warning when the number of entries is not the same for both arrays. Changes since v1: - fix EMIO_SD1_CD pin name - add USB to pinmux options changes since RFCv2: - let Zynq select PINCTRL_ZYNQ. Boot hangs when pinctrl information is present in DT but no driver available. - add #defines to get rid of magical constants - add commas at end of initializers - separate changes in mach-zynq in separate patch - add driver specific io-standard DT property - refactored pinconf set function to not require arguments for argument-less properties - squash other patches in - support for IO-standard property - support for low-power mode property - migration to pinconf_generic_dt_node_to_map_all() - use newly created infrastructure to add pass driver-specific DT params to pinconf-generic changes since RFC: - use syscon/regmap to access registers in SLCR space - rebase to 3.18: rename enable -> set_mux - add kernel-doc - support pinconf - supported attributes - pin-bias: pull up, tristate, disable - slew-rate: 0 == slow, 1 == fast; generic pinconf does not display argument Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Tested-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
