^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) - "realtek,dc_offset_l_manual"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) - "realtek,dc_offset_r_manual"

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) - "realtek,dc_offset_r_manual_mic"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)   Based on the different PCB layout, add the manual offset value to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)   compensate the DC offset for each L and R channel, and they are different
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25)   between headphone and headset.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) - "realtek,impedance_sensing_num"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27)   The matrix row number of the impedance sensing table.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28)   If the value is 0, it means the impedance sensing is not supported.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) - "realtek,impedance_sensing_table"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)   The matrix rows of the impedance sensing table are consisted by impedance
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)   minimum, impedance maximun, volume, DC offset w/o and w/ mic of each L and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32)   R channel accordingly. Example is shown as following.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33)   <   0    300  7  0xffd160  0xffd1c0  0xff8a10  0xff8ab0
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)     301  65535  4  0xffe470  0xffe470  0xffb8e0  0xffb8e0>
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35)   The first and second column are defined for the impedance range. If the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36)   detected impedance value is in the range, then the volume value of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37)   third column will be set to codec. In our codec design, each volume value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38)   should compensate different DC offset to avoid the pop sound, and it is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39)   also different between headphone and headset. In the example, the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40)   "realtek,impedance_sensing_num" is 2. It means that there are 2 ranges of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41)   impedance in the impedance sensing function.
