| | | | | | | | | | | | | | In commit f5339277 "powerpc: Remove FW_FEATURE ISERIES from arch code", we removed the bulk of the iSeries code, but missed a few bits. Remove the mschunks bits, these were only ever used on iSeries as far as I know, and are definitely not used anymore. Make it even clearer that phys_to_abs() is a nop, by making it a macro. We still have a few users of this, but should clean those up. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull OLPC platform updates from Andres Salomon: "These move the OLPC Embedded Controller driver out of arch/x86/platform and into drivers/platform/olpc. OLPC machines are now ARM-based (which means lots of x86 and ARM changes), but are typically pretty self-contained.. so it makes more sense to go through a separate OLPC tree after getting the appropriate review/ACKs." * 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc: x86: OLPC: move s/r-related EC cmds to EC driver Platform: OLPC: move global variables into priv struct Platform: OLPC: move debugfs support from x86 EC driver x86: OLPC: switch over to using new EC driver on x86 Platform: OLPC: add a suspended flag to the EC driver Platform: OLPC: turn EC driver into a platform_driver Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it drivers: OLPC: update various drivers to include olpc-ec.h Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver
| * x86: OLPC: move s/r-related EC cmds to EC driverAndres Salomon2012-07-31
| | | | | | | | | | | | | | | | | | | | | | The new EC driver calls platform-specific suspend and resume hooks; run XO-1-specific EC commands from there, rather than deep in s/r code. If we attempt to run EC commands after the new EC driver has suspended, it is refused by the ec->suspended checks.

| * Platform: OLPC: move debugfs support from x86 EC driverAndres Salomon2012-07-31
| | | | | | | | | | | | | | | | | | | | | | | | There's nothing about the debugfs interface for the EC driver that is architecture-specific, so move it into the arch-independent driver. The code is mostly unchanged with the exception of renamed variables, coding style changes, and API updates.

| | | | | | | | | | | | | | | | | | | | | | This uses the new EC driver framework in drivers/platform/olpc. The XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff (including a new workqueue; no more running EC commands with IRQs disabled!) can be shared with other architectures.

| * Platform: OLPC: add a suspended flag to the EC driverAndres Salomon2012-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | A problem we've noticed on XO-1.75 is when we suspend in the middle of an EC command. Don't allow that. In the process, create a private object for the generic EC driver to use; we have a framework for passing around a struct, use that rather than a proliferation of global variables.

| * Platform: OLPC: turn EC driver into a platform_driverAndres Salomon2012-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The 1.75-based OLPC EC driver already does this; let's do it for all EC drivers. This gives us nice suspend/resume hooks, amongst other things. We want to run the EC's suspend hooks later than other drivers (which may be setting wakeup masks or be running EC commands). We also want to run the EC's resume hooks earlier than other drivers (which may want to run EC commands).

| * Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call itAndres Salomon2012-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides a new API allows different OLPC architectures to override the EC driver. x86 and ARM OLPC machines use completely different EC backends. The olpc_ec_cmd is synchronous, and waits for the workqueue to send the command to the EC. Multiple callers can run olpc_ec_cmd() at once, and they will by serialized and sleep while only one executes on the EC at a time. We don't provide an unregister function, as that doesn't make sense within the context of OLPC machines - there's only ever 1 EC, it's critical to functionality, and it certainly not hotpluggable.

| | | | | | | | | | | | | | | | | | | | | | The OLPC EC driver has outgrown arch/x86/platform/. It's time to both share common code amongst different architectures, as well as move it out of arch/x86/. The XO-1.75 is ARM-based, and the EC driver shares a lot of code with the x86 code.
