* i2c: sunxi: add P2WI (Push/Pull 2 Wire Interface) controller supportBoris BREZILLON2014-06-121-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | The P2WI controller looks like an SMBus controller which only supports byte data transfers. But, it differs from standard SMBus protocol on several aspects: - it supports only one slave device, and thus drop the address field - it adds a parity bit every 8bits of data - only one read access is required to read a byte (instead of a write followed by a read access in standard SMBus protocol) - there's no Ack bit after each byte transfer This means this bus cannot be used to interface with standard SMBus devices (the only known device to support this interface is the AXP221 PMIC). However the P2WI protocol is close enough to SMBus to be integrated in the I2C subsystem (see this thread [1] for detailed reasons that led to integrating this driver in the I2C subsystem).

* | i2c: ChromeOS EC tunnel driverDoug Anderson2014-06-031-0/+9
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARM Chromebooks we have a few devices that are accessed by both the AP (the main "Application Processor") and the EC (the Embedded Controller). These are: * The battery (sbs-battery). * The power management unit tps65090. On the original Samsung ARM Chromebook these devices were on an I2C bus that was shared between the AP and the EC and arbitrated using some extranal GPIOs (see i2c-arb-gpio-challenge). The original arbitration scheme worked well enough but had some downsides: * It was nonstandard (not using standard I2C multimaster) * It only worked if the EC-AP communication was I2C * It was relatively hard to debug problems (hard to tell if i2c issues were caused by the EC, the AP, or some device on the bus). On the HP Chromebook 11 the design was changed to: * The AP/EC comms were still i2c, but the battery/tps65090 were no longer on the bus used for AP/EC communication. The battery was exposed to the AP through a limited i2c tunnel and tps65090 was exposed to the AP through a custom Linux driver. On the Samsung ARM Chromebook 2 the scheme is changed yet again, now: * The AP/EC comms are now using SPI for faster speeds. * The EC's i2c bus is exposed to the AP through a full i2c tunnel. The upstream "tegra124-venice2" uses the same scheme as the Samsung ARM Chromebook 2, though it has a different set of components on the other side of the bus. This driver supports the scheme used by the Samsung ARM Chromebook 2. Future patches to this driver could add support for the battery tunnel on the HP Chromebook 11 (and perhaps could even be used to access tps65090 on the HP Chromebook 11 instead of using a special driver, but I haven't researched that enough).

It got a little delayed because I needed to wait for a dependency to be included (commit b424080a9e08: "reset: Add optional resets and stubs"). Plus, I had some email problems. All done now, the highlights are: - drivers can now deprecate their use of i2c classes. That shouldn't be used on embedded platforms anyhow and was often blindly copy&pasted. This mechanism gives users time to switch away and ultimately boot faster once the use of classes for those drivers is gone for good. - new drivers for QUP, Cadence, efm32 - tracepoint support for I2C and SMBus - bigger cleanups for the mv64xxx, nomadik, and designware drivers And the usual bugfixes, cleanups, feature additions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT.
