* pwm: samsung: Fix kernel warning while unexporting a channelSachin Kamat2013-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | PWM channel data was set to NULL before freeing it. This caused the following kernel warning while unexporting the channel. Set the channel data to NULL after freeing it.

* pwm-backlight: Allow for non-increasing brightness levelsMike Dunn2013-10-161-14/+15
| | | | | | | | | | | | | Currently the driver assumes that the values specified in the brightness-levels device tree property increase as they are parsed from left to right. But boards that invert the signal between the PWM output and the backlight will need to specify decreasing brightness-levels. This patch removes the assumption that the last element of the array is the maximum value, and instead searches the array for the maximum value and uses that in the duty cycle calculation.

Unlike ordinary I/O ASIC interrupts DMA interrupts need to be deasserted by software by writing 0 to the respective bit in I/O ASIC's System Interrupt Register (SIR), similarly to how CP0.Cause.IP0 and CP0.Cause.IP1 bits are handled in the CPU (the difference is SIR DMA interrupt bits are R/W0C so there's no need for an RMW cycle). Otherwise the handler is reentered over and over again. The only current user is the DEC LANCE Ethernet driver and its extremely uncommon DMA memory error handler that does not care when exactly the interrupt is cleared. Anticipating the use of DMA interrupts by the Zilog SCC driver this change however exports clear_ioasic_dma_irq for device drivers to choose the right application-specific sequence to clear the request explicitly rather than calling it implicitly in the .irq_eoi handler of `struct irq_chip'. Previously these interrupts were cleared in the .end handler of the said structure, before it was removed. Signed-off-by: Maciej W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usage of strict_strtoul() and strict_strtol() is not preferred, because strict_strtoul() and strict_strtol() are obsolete. Thus, kstrtoul() and kstrtol() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the Samsung Q10 backlight driver to use ACPI methods (the same ones as triggered by the brightness up/down function keys) instead of direct EC calls. The advantage is that the brightness setting is not lost on shutdown. Signed-off-by: Frederick van der Wyck <fvanderwyck@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
