  • 2fccd2d96   tegra: Convert tegra GPIO driver to use driver model ... Browse Code »
    188

    This is an implementation of GPIOs for Tegra that uses driver model. It has
    been tested on trimslice and also using the new iotrace feature.

    The implementation uses a top-level GPIO device (which has no actual GPIOS).
    Under this all the banks are created as separate GPIO devices.

    The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
    ..., Z0..Z7, AA0..AA7, etc.

    Since driver model is not yet available before relocation, or in SPL, a
    special function is provided for seaboard's SPL code.

  • c0c374024   gpio: spear_gpio: Fix gpio_set_value() implementation ... Browse Code »

    In current gpio_set_value() implementation, it always sets the gpio control bit
    no matter the value argument is 0 or 1. Thus the GPIOs never set to low.
    This patch fixes this bug.

    The address bus is used as a mask on read/write operations, so that independent
    software drivers can set their GPIO bits without affecting any other pins in a
    single write operation. Thus we don't need a read-modify-write to update the
    register.

  • 54c5d08a0   dm: rename device struct to udevice ... Browse Code »

    using UBI and DM together leads in compiler error, as
    both define a "struct device", so rename "struct device"
    in include/dm/device.h to "struct udevice", as we use
    linux code (MTD/UBI/UBIFS some USB code,...) and cannot
    change the linux "struct device"

    We need check the NULL pointer as at91_pio_get_port() may return NULL.

    Also print a error message when at91_pio_get_port() failed otherwise we
    cannot notice the failure.

  • eceb3f26f   ARM: tegra: add GPIO initialization table function ... Browse Code »

    The HW-defined procedure for booting Tegra requires that some pins be
    set up as GPIOs immediately at boot in order to avoid glitches on those
    pins, when the pinmux is programmed. Add a feature to the GPIO driver
    which executes a GPIO configuration table. Board files will use this to
    implement the correct HW initialization procedure.

  • f6ae1ca05   S5P: Exynos: Add GPIO pin numbering and rename definitions ... Browse Code »

    This patch includes following changes :
    * Adds gpio pin numbering support for EXYNOS SOCs.
    To have consistent 0..n-1 GPIO numbering the banks are divided
    into different parts where ever they have holes in them.

    * Rename GPIO definitions from GPIO_... to S5P_GPIO_...
    These changes were done to enable cmd_gpio for EXYNOS and
    cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
    getting a error during compilation.

    * Adds support for name to gpio conversion in s5p_gpio to enable
    gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
    to decode the input gpio name to gpio number.
    Example: SMDK5420 # gpio set gpa00

  • 96495d90f   dm: Add GPIO support and tests ... Browse Code »

    Add driver model support for GPIOs. Since existing GPIO drivers do not use
    driver model, this feature must be enabled by CONFIG_DM_GPIO. After all
    GPO drivers are converted over we can perhaps remove this config.

    Tests are provided for the sandbox implementation, and are a sufficient
    sanity check for basic operation.

    The GPIO uclass understands the concept of named banks of GPIOs, with each
    GPIO device providing a single bank. Within each bank the GPIOs are numbered
    using an offset from 0 to n-1. For example a bank named 'b' with 20
    offsets will provide GPIOs named b0 to b19.

    Anonymous GPIO banks are also supported, and are just numbered without any
    prefix.

    Each time a GPIO driver is added to the uclass, the GPIOs are renumbered
    accordinging, so there is always a global GPIO numbering order.

  • bcd4d4eb2   SPDX-License-Identifier: fixing some problematic GPL-2.0 files ... Browse Code »

    Unlike the other patches in this series so far, this commit fixes a
    ambiguity in the license terms for some OMAP files: the code was
    originally derived from the Linux kernel sources, where it was clearly
    marked as GPL-2.0 (i. e. without the "or later" part), but the U-Boot
    version had a GPL-2.0+ file header added, apparently without
    permission / relicensing from the original authors of the code.

    Insert a GPL-2.0 SPDX-License-Identifier to fix this.

  • 87bd05d78   ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5 ... Browse Code »

    The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs.
    These SoCs have different gpio count but currently omap_gpio driver uses hard
    coded 192 which is wrong.

    This patch fixes this issue by:
    1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h.
    2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5.

    Thanks for Lubomir Popov to provide valuable comments to fix this issue.
