Kuogee Hsieh ea530388e6 drm/msm/dp: skip checking LINK_STATUS_UPDATED bit ... Some dongle will not clear LINK_STATUS_UPDATED bit after DPCD read which cause link training failed. This patch just read 6 bytes of DPCD link status from sink and return without checking LINK_STATUS_UPDATED bit. Only 8 bits are used to represent link rate at sinker DPCD. The really link rate is 2.7Mb times the 8 bits value. For example, 0x0A at DPCD is equal to 2.7Gb (10 * 2.7Mb). This patch also convert 8 bits value of DPCD to really link rate to fix worng link rate error during phy compliance test.
