gpio: fix wrong checking condition for gpio range

2013-04-17T04:48:29+00:00

commit ad4e1a7caf937ad395ced585ca85a7d14395dc80 upstream.

If index++ calculates from 0, the checking condition of "while
(index++)" fails & it doesn't check any more. It doesn't follow
the loop that used at here.

Replace it by endless loop at here. Then it keeps parsing
"gpio-ranges" property until it ends.

gpio: stmpe: pass DT node to irqdomain

2013-04-12T16:52:03+00:00

commit 9afd9b7090225d78ef56423a2ff65354dc38f1b1 upstream.

The irq domain was implemented but the device tree
node was not transmitted to irq_domain_add_simple().

gpio: mvebu: Add clk support to prevent lockup

2013-03-14T18:26:36+00:00

commit de88747f514a4e0cca416a8871de2302f4f77790 upstream.

The kirkwood SoC GPIO cores use the runit clock. Add code to
clk_prepare_enable() runit, otherwise there is a danger of locking up
the SoC by accessing the GPIO registers when runit clock is not
ticking.

gpio: em: Use irq_domain_add_simple() to fix runtime error

2013-02-28T13:38:41+00:00

commit c7886b18273b07042e25e8d3ba5c983837b84123 upstream.

Adjust the gpio-em.c driver to reconsider the pdata->irq_base
variable. Non-DT board code like for instance board-kzm9d.c
needs to operate of a static IRQ range for platform devices.

So this patch is updating the code to make use of the function
irq_domain_add_simple() instead of irq_domain_add_linear().

Fixes a EMEV2 / KZM9D runtime error caused by the following commit:

gpio: mvebu: Don't free chip label memory

2013-01-17T11:27:08+00:00

The gpio_chip.label field is a const char * and assigned the value of a
call to dev_name(). Memory obtained from dev_name() should not be freed
by drivers.

gpio: samsung: skip gpio lib registration for EXYNOS5440

2013-01-17T10:53:54+00:00

Since exynos5440 can support pinctrl so skip the legacy
gpiolib registration. If not, happens following.

gpio: samsung: silent build warning for EXYNOS5 SoCs

This patch fixes following warning:

drivers/gpio/gpio-samsung.c:450:32: warning: 'exynos_gpio_cfg' defined but not used [-Wunused-variable]
drivers/gpio/gpio-samsung.c:2450:33: warning: 'exynos5_gpios_1' defined but not used [-Wunused-variable]

drivers/gpio/gpio-samsung.c:2715:33: warning: 'exynos5_gpios_4' defined but not used [-Wunused-variable]

Because current gpio-samsung is valid only on EXYNOS5250.

gpio: samsung: fix pinctrl condition for exynos and exynos5440

2013-01-17T08:17:59+00:00

Since EXYNOS5440 can select PINCTRL_EXYNOS5440 without PINCTRL_SAMSUNG,
it should be fixed. In detail, PINCTRL_SAMSUNG is a kind of frame work
for supporting pinctrl on most Samsung SoCs including S3C, S5P as well
except EXYNOS5440 so PINCTRL_EXYNOS5440 has been implemented separated.

Drivers: misc: remove __dev* attributes.

2013-01-03T23:57:16+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
