30000 ticks, which may be 300 seconds if HZ is 100, for example, some arm64

The issue was reported and described in details by Lothar Waßmann and
Christian Gmeiner in https://lkml.org/lkml/2014/9/9/123.

Fix it by adding missed call of gpiochip_set_chained_irqchip()
so GPIO IRQ chip helpers will set parent_irq for nested IRQs
properly.

      由 Grygorii Strashko 提交于 
      OMAP GPIO driver allowed to be built as loadable module, but it
doesn't set owner field in GPIO chip structure. As result,
module_get/put() API is not working and it's possible to unload
OMAP driver while in use:

      gpio: max732x: Add missing dev reference to gpiochip · 34ab54ed
      由 Marek Vasut 提交于 
      In case the gpiochip doesn't have the .dev field set, as is the case
in here, it is not possible to reference this device in DT as a GPIO
controller. A good example of this problem is that gpio-leds can not
be used when connected to this chip, the gpio-leds driver bails out
with -EPROBE_DEFER.

Fix this problem by setting the .dev field of the gpio_chip to the
parent i2c device.

      gpio/xilinx: Use correct address when setting initial values. · 5b2c9121
      由 Raphaël Teysseyre 提交于 
      xgpio_save_regs() is used in this driver to setup the initial
values of the registers in the hardware.

The relevant registers at that time are:
0x0 -> channel 0 data (32 bits, one for each GPIO on this channel).
0x4 -> channel 0 tri, controls in/out status for each GPIO of this channel.
0x8 -> channel 1 data
0xC -> channel 1 tri

gpio-xilinx.c defines these:
XGPIO_DATA_OFFSET   (0x0)
XGPIO_TRI_OFFSET    (0x4)
XGPIO_CHANNEL_OFFSET	0x8

Before this patch, the "data" register value of channel 1 was written
at 0x4 intead of 0x8 (overwriting the channel 0 "tri" register),
and the "tri" register value for channel 1 was written at 0x8 instead of 0xC.

      This laptop needs GPIO4 pulled high to enable the headphone amplifier,
and has a mute LED on GPIO3. I modelled the patch on the existing
GPIO4 code which pulls the line low for the same purpose; this time,
the HP amp line is pulled high.

v2: Disable the headphone amplifier when no headphone is connected.
    Don't disable power savings to preserve the LED state.

v3: Remove headset-specific hooks and code; this is just a headphone.
