drivers: gpio: omap: add support for parsing additional gpio parameters

2015-10-22T18:44:02Z

With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be parsed in xlate gpio drivers-ops. Since xlate is not implemented in omap_gpio driver, the driver considers all gpio to be ACTIVE_HIGH which is the default case and fails to return actual gpio status for ACTIVE_LOW gpios. So adding .xlate ops to omap_gpio. Signed-off-by: Mugunthan V N Reviewed-by: Tom Rini Reviewed-by: Simon Glass

sunxi: power: Unify axp pmic function names

2015-10-20T16:40:27Z

Stop prefixing the axp functions for setting voltages, etc. with the model number, there ever is only one pmic driver built into u-boot, this allows simplifying the callers. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

gpio: s5p: call: dev_get_addr() instead of fdtdec_get_addr()

2015-10-03T13:39:19Z

After rework in lib/fdtdec.c, the function fdtdec_get_addr() doesn't work for nodes with #size-cells property set to 0. To get GPIO's 'reg' property, the code should use one of: fdtdec_get_addr_size_auto_no/parent() function. Fortunately dm core provides a function to get the property. This commit reworks function gpio_exynos_bind(), to properly use dev_get_addr() for GPIO device. This prevents setting a wrong base register for Exynos GPIOs. Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon). Signed-off-by: Przemyslaw Marczak Acked-by: Stephen Warren Acked-by: Simon Glass Tested-by: Simon Glass

gpio: tegra: use named constants

2015-10-02T18:05:56Z

In order to make it clear what the parameters to set_config() and set_direction() mean, and similarly for the return values from the respective get_*(), define named constants for these values. Disassembly shows no diff in the generated code, except that the order of the code in the branches of tegra_gpio_get_function() gets modified without affecting behaviour.

ARM: tegra: don't enable GPIOs until direction is set

2015-10-02T18:05:01Z

Tegra's GPIO driver currently enables pins as GPIO as soon as they're requested. This is not safe, since the desired direction and output value are not yet known. This could cause a glitch on the output pins between gpio_request() and gpio_direction_*(), depending on what values happen to be in the GPIO controller's in/out and out-value registers vs. the final desired configuration. To solve this, defer enabling pins as GPIOs until some gpio_direction_*() is invoked, and the desired configuration is explicitly programmed. In theory this change could cause regressions, if code exists that claims a GPIO, never explicitly sets a direction, and then gets/sets the GPIO value based on that assumption. However, I've read through all the Tegra- related board files and device drivers that touch GPIOs and I do not see such buggy code anywhere.

ARM: tegra: fix GPIO init table programming

2015-10-02T18:04:34Z

Tegra's gpio_config_table() currently uses common GPIO APIs. These used to work without requesting the GPIO, but since commit 2fccd2d96bad "tegra: Convert tegra GPIO driver to use driver model" no longer do so. This prevents any of the GPIO initialization table from being applied to HW. Fix gpio_config_table() to directly program the HW to solve this.
