SW can trigger MIPI pads calibration any time after power on but calibration results will be latched and applied to the pads by MIPI CAL unit only when the link is in LP-11 state and then status register will be updated. For CSI, trigger of pads calibration happen during CSI stream enable where CSI receiver is kept ready prior to sensor or CSI transmitter stream start. So, pads may not be in LP-11 at this time and waiting for the calibration to be done immediate after calibration start will result in timeout. This patch splits tegra_mipi_calibrate() and tegra_mipi_wait() so triggering for calibration and waiting for it to complete can happen at different stages.
