* GPIO: gpio-pxa: fix building without CONFIG_OFArnd Bergmann2012-08-141-2/+2
| | | | | | | | | | | | | | | | Commit 7212157267 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.

* GPIO: gpio-pxa: fix devicetree functionsDaniel Mack2012-08-051-0/+26
| | | | | | | | | | | Provide an of_xlate function for the PXA GPIO chips and make it work for devicetree environments. Successfully tested on a PXA3xx board.

| | | | | | | | Parse GPIO numbers from DTS file. Allocate interrupt according to GPIO numbers. Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
* ARM: pxa: fix gpio wakeup settingRobert Jarzmik2012-04-271-2/+19
| | | | | | | | | | | | | | In 3.3, gpio wakeup setting was broken. The call enable_irq_wake() didn't set up the PXA gpio registers (PWER, ...) anymore. Fix it at least for pxa27x. The driver doesn't seem to be used in pxa25x (weird ...), and the fix doesn't extend to pxa3xx and pxa95x (which don't have a gpio_set_wake() available).

* gpio: pxa: explicitly include mach/irqs.hRob Herring2012-01-261-0/+2
| | | | | | | In preparation to make mach/irqs.h optional and remove from asm/irq.h, directly include mach/irq.h to get MMP_GPIO_TO_IRQ and PXA_GPIO_TO_IRQ. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
* ARM: pxa: add clk support in gpio driverHaojian Zhuang2011-11-151-1/+25
| | | | | | | | Support clk in gpio driver. There's no gpio clock in PXA25x and PXA27x. So use dummy clk instead. And move the gpio edge initialization into gpio driver for arch-mmp. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
* ARM: mmp: clear gpio edge detectHaojian Zhuang2011-11-151-0/+4
| | | | | | Append code to clear gpio edge detect in gpio-pxa driver. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
* ARM: pxa: change gpio to platform deviceHaojian Zhuang2011-11-151-10/+125
| | | | | | Remove most gpio macros and change gpio driver to platform driver. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
* ARM: pxa: use little endian read write in gpio driverHaojian Zhuang2011-11-141-34/+34
| | | | | | | Remove __raw_readl()/__raw_writel(). Use readl_relaxed()/writel_relaxed() instead. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
* ARM: pxa: recognize gpio number and typeHaojian Zhuang2011-11-141-1/+40
| | | | | | | Use cpuid to recognize the gpio number and type. CPU_PXA26x is the special case since we can't identify it by cpuid. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
* ARM: pxa: rename gpio_to_irq and irq_to_gpioHaojian Zhuang2011-11-141-4/+85
| | | | | | | Avoid to define gpio_to_irq() and irq_to_gpio() for potential name confliction since multiple architecture will be built together. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
* ARM: pxa: use chained interrupt for GPIO0 and GPIO1Haojian Zhuang2011-11-141-0/+14
| | | | | | | | | | | | | GPIO0 and GPIO1 are linked to unique interrupt line in PXA series, others are linked to another interrupt line. All GPIO are linked to one interrupt line in MMP series. Since gpio driver is shared between PXA series and MMP series, define GPIO0 and GPIO1 as chained interrupt chip. So we can move out gpio code from irq.c to gpio-pxa.c.
