Subject: ARM: tegra: tf600t: Invert accelerometer calibration matrix
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=774bc2764647cfd6b65727cfa978d809f11df392;p=thirdparty%2Fkernel%2Fstable.git

ARM: tegra: tf600t: Invert accelerometer calibration matrix

IMU calibration matrix used in the device tree is inverted when testing on
the device which results in wrong screen orientation. Invert it to match
the matrix dumped from the device.
