  • 69339d083   pinctrl: amd: fix npins for uart0 in kerncz_groups ... Browse Code »

    uart0_pins is defined as:
    static const unsigned uart0_pins[] = {135, 136, 137, 138, 139};

    which npins is wronly specified as 9 later
    {
    .name = "uart0",
    .pins = uart0_pins,
    .npins = 9,
    },

    npins should be 5 instead of 9 according to the definition.

  • 1766e4b70   pinctrl/amd: fix gpio irq level in debugfs ... Browse Code »

    According to the AMD BKDG, the GPIO ActiveLevel bits (10:9) map to:
    00 Active High
    01 Active Low
    10 Active on both edges iff LevelTrig (bit 8) == 0
    11 Reserved

    The current code has a bug where it interprets 00 => Active Low, and
    01 => Active High.

    Fix the bug, restrict "Active on both" to just the edge trigger case, and
    refactor a bit to make the logic more readable.

  • 79d2c8bed   pinctrl/amd: save pin registers over suspend/resume ... Browse Code »

    The touchpad in the Asus laptop models X505BA/BP and X542BA/BP is
    unresponsive after suspend/resume. The following error appears during
    resume:

    i2c_hid i2c-ELAN1300:00: failed to reset device.

    The problem here is that i2c_hid does not notice the interrupt being
    generated at this point, because the GPIO is no longer configured
    for interrupts.

    Fix this by saving pinctrl-amd pin registers during suspend and
    restoring them at resume time.

    Based on code from pinctrl-intel.

  • 229710fec   pinctrl: amd: make use of raw_spinlock variants ... Browse Code »

    The amd pinctrl drivers currently implement an irq_chip for handling
    interrupts; due to how irq_chip handling is done, it's necessary for the
    irq_chip methods to be invoked from hardirq context, even on a a
    real-time kernel. Because the spinlock_t type becomes a "sleeping"
    spinlock w/ RT kernels, it is not suitable to be used with irq_chips.

    A quick audit of the operations under the lock reveal that they do only
    minimal, bounded work, and are therefore safe to do under a raw spinlock.
