x86/olpc/xo1/sci: Report RTC wakeup events

2012-05-07T13:02:26+00:00

When the system is woken due to a RTC event, report the wakeup event on the relevant rtc device (if it can be found). Signed-off-by: Daniel Drake Cc: dilinger@queued.net Cc: pgf@laptop.org Link: http://lkml.kernel.org/r/20120418223402.D73249D401E@zog.reactivated.net Signed-off-by: Ingo Molnar

x86, olpc: Add XO-1 RTC driver

2011-07-06T21:44:42+00:00

Add a driver to configure the XO-1 RTC via CS5536 MSRs, to be used as a system wakeup source via olpc-xo1-pm. Device detection is based on finding the relevant device tree node.

x86, olpc-xo1-sci: Add lid switch functionality

2011-07-06T21:44:39+00:00

Configure the XO-1's lid switch GPIO to trigger an SCI interrupt, and correctly expose this input device which can be used as a wakeup source.

x86, olpc-xo1-sci: Add GPE handler and ebook switch functionality

2011-07-06T21:44:38+00:00

The EC in the OLPC XO-1 delivers GPE events to provide various notifications. Add the basic code for GPE/EC event processing and enable the ebook switch, which can be used as a wakeup source.

x86, olpc: Add XO-1 SCI driver and power button control

2011-07-06T21:44:34+00:00

The System Control Interrupt is used in the OLPC XO-1 to control various features of the laptop. Add the driver base and the power button functionality. This driver can't be built as a module, because functionality added in future patches means that some drivers need to know at boot-time whether SCI-based functionality is available.

x86, olpc: Add XO-1 suspend/resume support

2011-07-06T21:44:32+00:00

Add code needed for basic suspend/resume of the XO-1 laptop. Based on earlier work by Jordan Crouse, Andres Salomon, and others. This patch incorporates all earlier feedback from Thomas Gleixner. To clarify a certain point (now more obvious in the code itself): On resume, OpenFirmware returns execution to Linux in protected mode with a kernel-compatible GDT already set up. The changes and simplifications suggested have all been included.

drivers/staging/olpc_dcon: convert to new cs5535 gpio API

2011-01-13T16:03:13+00:00

Drop the old geode_gpio crud, as well as the raw outl() calls; instead, use the Linux GPIO API where possible, and the cs5535_gpio API in other places. Note that we don't actually clean up the driver properly yet (once loaded, it always remains loaded). That'll come later.. This patch is necessary for building the driver.

drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO functionality

2011-01-13T16:03:13+00:00

This adds (well, re-adds actually) handling for events/IRQs through cs5535 GPIOs. In the wild and wooly world of CS5535, setup_event() is for assigning an IRQ to a GPIO filter/event pair, and set_irq() sets up the pair to trigger IRQs. These should really only be used in highly platform-specific drivers (such as OLPC's DCON driver). Sadly, because set_irq() uses MSRs, this causes the driver to become X86-specific.
