2011-07-06x86, olpc: Add XO-1 RTC driverDaniel Drake1-0/+5
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.

2011-07-06x86, olpc-xo1-sci: Add GPE handler and ebook switch functionalityDaniel Drake1-0/+22

2011-07-06x86, olpc: Add XO-1 SCI driver and power button controlDaniel Drake1-0/+8
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.

2011-07-06x86, olpc: Add XO-1 suspend/resume supportDaniel Drake1-0/+3
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.

2011-01-13drivers/staging/olpc_dcon: convert to new cs5535 gpio APIAndres Salomon1-0/+4
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.

2011-01-13drivers/gpio/cs5535-gpio.c: add some additional cs5535-specific GPIO ↵Andres Salomon1-0/+2
functionality 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.

2009-12-15cs5535: add a generic MFGPT driverAndres Salomon1-0/+67
This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's not x86 specific, it's modular, and it makes use of a PCI BAR rather than a random MSR. Currently module unloading is not supported; it's uncertain whether or not it can be made work with the hardware.

2009-12-15cs5535-gpio: add AMD CS5535/CS5536 GPIO driver supportAndres Salomon1-0/+58
This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend (allowing GPIO users to use the generic GPIO API if desired) while also allowing architecture-specific users directly (via the cs5535_gpio_* functions). Tested on an OLPC machine. Some Leemotes also use CS5536 (with a mips cpu), which is why this is in drivers/gpio rather than arch/x86. Currently, it conflicts with older geode GPIO support; once MFGPT support is reworked to also be more generic, the older geode code will be removed.
