  • For i945 and earlier chips, the backlight frequency value had the low
    bit (of 16) fixed to zero. The Pineview code path handled this by just
    exposing the backlight range as 15 bits while other chips had the
    backlight range limited to 0 .. 0xfffe.

    This patch makes everyone take the pineview code path, providing 15
    bits of backlight duty cycle range which seems more than sufficient to
    me.

    Daniel Mack reported that writing 1 to bit 0 of the duty cycle
    register was causing problems on his Samsung X20 notebook, even when
    the duty cycle value was less than the maximum backlight value. (He
    tried a value of 29749 with max_brightness of 29750). This patch never
    writes a '1' to that bit.

  • The Ivybridge eDP control register looks like a cross between a
    Cougarpoint PCH DP control register and a Sandybridge eDP control
    register.

    Where things trivially match, share the code. Where there are any
    tricky bits, just split things out into two obviously separate code paths.

  • On IVB C0+ with newer BIOSes, the forcewake handshake has changed. There's
    now a bitfield for different driver components to keep the GT powered
    on. On Linux, we centralize forcewake handling in one place, so we
    still just need a single bit, but we need to use the new registers if MT
    forcewake is enabled.

    This needs testing on affected machines. Please reply with your
    tested-by if you had problems after a BIOS upgrade and this patch fixes
    them.

    v2: force MT mode. shift by 16
    v3: set MT force wake bits then check ECOBUS

  • Count of selector voltage is required for regulator_set_voltage
    to work via set_voltage_sel. VDD1/2 currently have it as zero,
    so regulator_set_voltage won't work for VDD1/2.
    Update count (n_voltages) for VDD1/2.

    Output Voltage = (step value * 12.5 mV + 562.5 mV) * gain

    With above expr, number of voltages that can be selected is
    step value count * gain count

    constant for gain count will be called VDD1_2_NUM_VOLT_COARSE

    existing constant for step value count is VDD1_2_NUM_VOLTS,
    use VDD1_2_NUM_VOLT_FINE instead to make clear that step value
    is not the only component in deciding selectable voltage count

  • 10-bit addresses overlap with traditional 7-bit addresses, leading in
    device name collisions. Add an arbitrary offset to 10-bit addresses to
    prevent this collision. The offset was chosen so that the address is
    still easily recognizable.

  • There is a potential integer overflow in drm_mode_dirtyfb_ioctl()
    if userspace passes in a large num_clips. The call to kmalloc would
    allocate a small buffer, and the call to fb->funcs->dirty may result
    in a memory corruption.

  • This reverts commit dc9372808412edbc653a675a526c2ee6c0c14a91.

    As requested by Ben Herrenschmidt:
    "This breaks some powerpc platforms at least. The practice of having
    a node provide an explicit "interrupt-parent" property pointing to
    itself is an old trick that we've used in the past to allow a
    device-node to have interrupts routed to different controllers.

    In that case, the node also contains an interrupt-map, so the node is
    its own parent, the interrupt resolution hits the map, which then can
    route each individual interrupt to a different parent."

    Grant says:
    "Ah, nuts, yes that is broken then. Yes, please revert the commit and
    Rob & I will come up with a better solution.

    Rob, I think it can be done by explicitly checking for np ==
    desc->interrupt_parent in of_irq_init() instead of relying on
    of_irq_find_parent() returning NULL."

  • Split the quirks and i2c_rec assignment into separate
    functions used by both radeon_lookup_i2c_gpio() and
    radeon_atombios_i2c_init(). This avoids duplicating code
    and cases where quirks were only added to one of the
    functions.
