However, if an LVDS display is attached (like in laptop) the active pipe variable is never set. The default value is PIPE_A and can be wrong. Set up the pipe variable during driver initialization after hardware state was read. Also, the detection of the active display (and hence the pipe) is wrong. The pipes are assigned to so called planes. Both pipes are always enabled on my laptop but only one plane is enabled (the plane A for the CRT or the plane B for the LVDS). Change active pipe detection code to take into account a status of the plane assigned to each pipe. The problem is visible in the 8 bpp mode if colors above 15 are used. The first 16 color entries are displayed correctly.

report changes on the input pins through an *INT pin. This patch implements a very basic way for the platform code to be alerted when some input changes (both edge detection). It can be seen as a poor man irq_chip. Alternatively, this could be turned into a full-fledged irq_chip, though I'm not sure it is worth the complexity. The driver has been tested on an Arcom Zeus.

i2c_client or spi_device) isn't wakeup capable. For I2C devices there is I2C_CLIENT_WAKE flag exists that we can pass via board info, and if set, I2C core will initialize wakeup capability. For SPI devices there is no such flag at all. I believe that it's not platform code responsibility to allow or disallow wakeups, instead, drivers themselves should set the capability if a device can trigger wakeups. That's what drivers/base/power/sysfs.c says: * It is the responsibility of device drivers to enable (or disable) * wakeup signaling as part of changing device power states, respecting * the policy choices provided through the driver model. I2C and SPI RTC devices send wakeup events via interrupt lines, so we should set the wakeup capability if IRQ is routed. Ideally we should also check irq for wakeup capability before setting device's capability, i.e. if (can_irq_wake(irq)) device_set_wakeup_capable(&client->dev, 1); But there is no can_irq_wake() call exist, and it is not that trivial to implement it for all interrupts controllers and complex/cascaded setups. drivers/base/power/sysfs.c also covers these cases: * Devices may not be able to generate wakeup events from all power * states. Also, the events may be ignored in some configurations; * for example, they might need help from other devices that aren't * active So there is no guarantee that wakeup will actually work, and so I think there is no point in being pedantic wrt checking IRQ wakeup capability.

There is a small window which rtc methods can be called before pdata->rtc is initialized. And there is no need use the irq_lock to protect hardware registers. The driver's own spinlock shoule be enough. - Check pdata->rtc before calling rtc_update_irq. - Use alarm_irq_enable and remove ioctl routine. - Use devres APIs and simplify error/remove path.

Here hpet rtc emulation is used. Problem is that rtc hpet comparator, isn't reinitialized after resume. Easiest way to solve this, is always mask all hpet interrupts on suspend This is triggered, when suspending with alarm set. Otherwise, hpet driver will think it doesn't need to reinitialize the rtc comparator, thus rtc interrupts won't work. This emulation isn't need for wakealarm.

to send mount requests to ->lookup(). But then we can not rely on d_unhased() to give reliable results because it may be called at any time by any code path. The d_unhashed() function is used by __simple_empty() in the path walking callbacks but autofs mount point dentrys should have no directories at all so a list_empty() on d_subdirs should be (and is) sufficient.
