This patch series adds the mount-matrix to several iio sensor drivers used in handheld devices. The mount-matrix translates the quite arbitrary orientation of the sensor on some printed circuit board to user-tangible orientation in handheld devices that relates to typical screen orientation. There was a bindings documentation by Linus Walleij but the patch did not make it into mainline. Therefore I resend it here. Next I have added some clarifications (at least I hope it clarifies) in a second patch. Finally, the patch set implements the hooks for the mount matrix in several iio drivers: bmc150, bma180, bmg160, itg3200, hmc5843. This includes also one patch for the bma180 to convert it to devm API. We use them in different variants of the omap3-gta04 so a separate patch set will provide device tree additions for them. H.
