From mboxrd@z Thu Jan 1 00:00:00 1970 From: Linus Walleij Subject: [PATCH 147/182] powerpc: ppc4xx: use gpiochip data pointer Date: Wed, 9 Dec 2015 14:41:39 +0100 Message-ID: <1449668499-5071-1-git-send-email-linus.walleij@linaro.org> Return-path: Received: from mail-lf0-f48.google.com ([209.85.215.48]:36599 "EHLO mail-lf0-f48.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751585AbbLINln (ORCPT ); Wed, 9 Dec 2015 08:41:43 -0500 Received: by lfs39 with SMTP id 39so34630400lfs.3 for ; Wed, 09 Dec 2015 05:41:42 -0800 (PST) Sender: linux-gpio-owner@vger.kernel.org List-Id: linux-gpio@vger.kernel.org To: linux-gpio@vger.kernel.org, Johan Hovold , Alexandre Courbot , Michael Welling , Markus Pargmann , Anatolij Gustschin , Benjamin Herrenschmidt , Paul Mackerras , Michael Ellerman Cc: Linus Walleij This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Cc: Anatolij Gustschin Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Cc: Michael Ellerman Signed-off-by: Linus Walleij --- Power maintainers: please ACK this. This looks like a pretty clean GPIO driver that should ideally move to drivers/gpio. It should be fine to change the include from to on this as it does not appear to use the consumer API. --- arch/powerpc/sysdev/ppc4xx_gpio.c | 16 +++++----------- 1 file changed, 5 insertions(+), 11 deletions(-) diff --git a/arch/powerpc/sysdev/ppc4xx_gpio.c b/arch/powerpc/sysdev/ppc4xx_gpio.c index fc65ad1b3293..96145ea09835 100644 --- a/arch/powerpc/sysdev/ppc4xx_gpio.c +++ b/arch/powerpc/sysdev/ppc4xx_gpio.c @@ -27,7 +27,7 @@ #include #include #include -#include +#include #include #include @@ -67,12 +67,6 @@ struct ppc4xx_gpio_chip { * There are a maximum of 32 gpios in each gpio controller. */ -static inline struct ppc4xx_gpio_chip * -to_ppc4xx_gpiochip(struct of_mm_gpio_chip *mm_gc) -{ - return container_of(mm_gc, struct ppc4xx_gpio_chip, mm_gc); -} - static int ppc4xx_gpio_get(struct gpio_chip *gc, unsigned int gpio) { struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc); @@ -97,7 +91,7 @@ static void ppc4xx_gpio_set(struct gpio_chip *gc, unsigned int gpio, int val) { struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc); - struct ppc4xx_gpio_chip *chip = to_ppc4xx_gpiochip(mm_gc); + struct ppc4xx_gpio_chip *chip = gpiochip_get_data(gc); unsigned long flags; spin_lock_irqsave(&chip->lock, flags); @@ -112,7 +106,7 @@ ppc4xx_gpio_set(struct gpio_chip *gc, unsigned int gpio, int val) static int ppc4xx_gpio_dir_in(struct gpio_chip *gc, unsigned int gpio) { struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc); - struct ppc4xx_gpio_chip *chip = to_ppc4xx_gpiochip(mm_gc); + struct ppc4xx_gpio_chip *chip = gpiochip_get_data(gc); struct ppc4xx_gpio __iomem *regs = mm_gc->regs; unsigned long flags; @@ -142,7 +136,7 @@ static int ppc4xx_gpio_dir_out(struct gpio_chip *gc, unsigned int gpio, int val) { struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc); - struct ppc4xx_gpio_chip *chip = to_ppc4xx_gpiochip(mm_gc); + struct ppc4xx_gpio_chip *chip = gpiochip_get_data(gc); struct ppc4xx_gpio __iomem *regs = mm_gc->regs; unsigned long flags; @@ -200,7 +194,7 @@ static int __init ppc4xx_add_gpiochips(void) gc->get = ppc4xx_gpio_get; gc->set = ppc4xx_gpio_set; - ret = of_mm_gpiochip_add(np, mm_gc); + ret = of_mm_gpiochip_add_data(np, mm_gc, ppc4xx_gc); if (ret) goto err; continue; -- 2.4.3
