2015-06-23backlight: pwm_bl: Simplify usage of devm_gpiod_get_optionalAxel Lin1-4/+2
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions), the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Simplify the usage of devm_gpiod_get_optional accordingly. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Don't clear the backlight level when we're going into suspend or blanking. Instead, just temporarily set the level to 0 so we retain the value when we resume.

2015-06-23backlight: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven1-3/+5
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

The gpio-backlight driver seems to be missing the MODULE_DEVICE_TABLE line which is preventing it from being modprobed during boot time even if the gpio-backlight device exists.

commit 257462dbf3ed ("pwm-backlight: switch to gpiod interface") introduced a regression leading to acquiring a bogus GPIO-0 when configured from DT without an 'enable-gpios' property. The driver will happily accept the 0 initialized 'enable_gpio' member of the struct platform_pwm_backlight_data as valid gpio number, and request this GPIO as enable pin. In case of multiple driver instances, the second will fail to register with the error message: pwm-backlight backlight1.23: failed to request GPIO#0: -16 Fix this by setting enable_gpio in the pdata struct to -EINVAL.

git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm Pull pwm changes from Thierry Reding: "The majority of these changes are cleanups and fixes across all drivers. Redundant error messages are removed and more PWM controllers set the .can_sleep flag to signal that they can't be used in atomic context. Support is added for the Broadcom Kona family of SoCs and the Intel LPSS driver can now probe PCI devices in addition to ACPI devices. Upon shutdown, the pwm-backlight driver will now power off the backlight. It also uses the new descriptor-based GPIO API for more concise GPIO handling. A large chunk of these changes also converts platforms to use the lookup mechanism rather than relying on the global number space to reference PWM devices. This is largely in preparation for more unification and cleanups in future patches.
