linux.git/drivers/mfd/Kconfig, branch v2.6.34 Linux kernel source tree mfd: Several MFD drivers should depend on GENERIC_HARDIRQS 2010-03-12T08:09:00+00:00 Geert Uytterhoeven geert@linux-m68k.org 2009-12-15T20:49:57+00:00 8d002bdc9f1f9a1220c0d87a7321f0233ace97cd commit 5fb4d38b19d95a5f980f0a10adba798f5b92128c ("mfd: Move WM831x to generic IRQ") didn't take into account that genirq support depends on GENERIC_HARDIRQS. Additionally, 2.6.34-rc1 added: - commit 2afa62ea76027b00e472ddb672191e6e15425b43 ("mfd: Use genirq in 88pm860x"). - commit 760e4518788df6762700e6bb9dd8692379f11168 ("mfd: Convert WM8350 to genirq"). - commit 1f1cf8f98cf6588365efeaab8e7e7758aaa77f6e ("mfd: Update irq handler in max8925") Make all of them depend on GENERIC_HARDIRQS to avoid compile errors on architectures that don't support genirq yet.

commit 5fb4d38b19d95a5f980f0a10adba798f5b92128c ("mfd: Move WM831x to
generic IRQ") didn't take into account that genirq support depends on
GENERIC_HARDIRQS.

Additionally, 2.6.34-rc1 added:
  - commit 2afa62ea76027b00e472ddb672191e6e15425b43 ("mfd: Use genirq in
    88pm860x").
  - commit 760e4518788df6762700e6bb9dd8692379f11168 ("mfd: Convert WM8350 to
    genirq").
  - commit 1f1cf8f98cf6588365efeaab8e7e7758aaa77f6e ("mfd: Update irq handler
    in max8925")

Make all of them depend on GENERIC_HARDIRQS to avoid compile errors on
architectures that don't support genirq yet.

on some smartphones, such as the HTC Wizard and HTC Herald.
It works through the I2C bus and acts as a GPIO extender.

 * it can have several sub-devices, each with its own I2C
   address
 * Each sub-device provides 8 output and 8 input pins
 * The chip attaches to one GPIO to signal when any of the
   input GPIOs change -- at which point all chips must be
   scanned for changes

This driver implements the GPIOs throught the kernel's
GPIO and IRQ framework.  This allows any GPIO-servicing
drivers to operate on htcpld pins, such as the gpio-keys
and gpio-leds drivers.
