module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab

blink_set(), the led can support hardware blinking for some values of
delay_on and delay_off and fall-back to software blinking for some other

My GPIOs are on an I2C port expander, so we must use the *_cansleep()
variant of the GPIO functions. This is was not being done in
create_gpio_led().We can change gpio_get_value() to gpio_get_value_cansleep() because it is
only called from the platform_driver probe function, which is a context

Add V2 of the LED driver for a single timer channel for the TPU hardware
block commonly found in Renesas SoCs.The driver has been written with optimal Power Management in mind, so to
save power the LED is driven as a regular GPIO pin in case of maximum
brightness and power off which allows the TPU hardware to be idle and
which in turn allows the clocks to be stopped and the power domain to be
turned off transparently.Any other brightness level requires use of the TPU hardware in PWM mode.
TPU hardware device clocks and power are managed through Runtime PM.
System suspend and resume is known to be working - during suspend the LED
is set to off by the generic LED code.The TPU hardware timer is equipeed with a 16-bit counter together with an
up-to-divide-by-64 prescaler which makes the hardware suitable for
brightness control. Hardware blink is unsupported.The LED PWM waveform has been verified with a Fluke 123 Scope meter on a
sh7372 Mackerel board. Tested with experimental sh7372 A3SP power domain
patches. Platform device bind/unbind tested ok.V2 has been tested on the DS2 LED of the sh73a0-based AG5EVM.

This new driver replaces the old PCEngines Alix 2/3 LED driver with a
new driver that controls the LEDs through the leds-gpio driver. The
old driver accessed GPIOs directly, which created a conflict and
prevented also loading the cs5535-gpio driver to read other GPIOs on
the Alix board. With this new driver, we hook into leds-gpio which in
turn uses GPIO to control the LEDs and therefore it's possible to
control both the LEDs and access onboard GPIOsDriver is moved to platform/geode as requested by Grant and any other
geode initialisation modules should move here alsoThis driver is inspired by leds-net5501.c by Alessandro Zummo.
Ideally, leds-net5501.c should also be moved to platform/geode.
Additionally the driver relies on parts of the patch: 7f131cf3ed ("leds:
leds-alix2c - take port address from MSR) by Daniel Mack to perform
detection of the Alix board.[akpm@linux-foundation.org: include module.h]
