2016-06-21pinctrl: sh-pfc: Improve core and user API separationGeert Uytterhoeven
The Renesas Pin Function Controller uses two header files: - sh_pfc.h, for use by both core code and SoC-specific drivers, - core.h, for internal use by the core code only. Several SoC-specific drivers include core.h, as they need the sh_pfc structure, which is passed explicitly to the various SoC-specific callbacks, and used there. Hence move its definition from core.h to sh_pfc.h, and remove the inclusion of core.h from all SoC-specific files.

2015-10-20pinctrl: sh-pfc: Rename .gpio_data[] to .pinmux_data[]Geert Uytterhoeven
The sh_pfc_soc_info.gpio_data[] array contains not only GPIO data, but also various other pinmux-related data (functions and marks). Every single driver already calls its local array pinmux_data[]. Hence rename the sh_pfc_soc_info member to "pinmux_data".

2015-10-02pinctrl: sh-pfc: Remove hardcoded IRQ numbersLaurent Pinchart
Now that all ARM-based Renesas SoCs use multiplatform kernels only the hardcoded IRQ numbers can be dropped as they're dynamically allocated.

2015-05-12pinctrl: sh-pfc: r8a73a4: Remove obsolete multi-platform checkGeert Uytterhoeven
As of commit 9d07d414d4c33d86 ("ARM: shmobile: r8a73a4: ape6evm: Remove legacy platform"), r8a73a4 is only supported in generic ARM multi-platform builds. Hence CONFIG_ARCH_MULTIPLATFORM is always set, and the check can be removed.

2014-09-04pinctrl: sh-pfc: rename confusing pinmux ops variableLinus Walleij
The vtable named *pinmux_ops in the affected files are not really about pin multiplexing, but a struct related to some PFC-specific operations, inclusing pin config (bias setting). Rename the variable so as to avoid confusions. Acked-by: Laurent Pinchart <Laurent.pinchart@ideasonboard.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-07-29sh-pfc: Replace pinmux_enum_id typedef with u16Laurent Pinchart
The typedef only conceals the real variable type without bringing any additional value (see Documentation/CodingStyle, section 5.b). Moreover, it polutes the pinmux namespace.
