Why 2 and 4 lane configurations set registers 0x3000, 0x3003, and 0x300e differently:

 static const struct ov8856_mode_regs ov8856_mode_lanes_regs[] = {
-	[OV8856_2_LANES] = {
+	[OV8856_4_LANES] = {
 	/* 3280x2464 resolution */
-		{{0x3000, 0x00},
-		{0x300e, 0x00},
+		{{0x3000, 0x20},
+		{0x3003, 0x08},
+		{0x300e, 0x20},

(and the same changes in the table for 1640x1232 resolution)

These three registers are not related to the MIPI lanes configuration, right?
So this change is not needed for adding support for 2 data lanes.

- in the 4-lanes case this register is set to 0x10. But it looks like
  this is not related to the MIPI interface configuration, right?

- register 0x3d85 is set to 0x14 in the 2 lanes case vs 0x17 in the 4 lanes case,
  but this register is not related to MIPI lanes control.
  Is this change really needed?

The 13 {register, value} pairs below break the "sort by reg address" order:

> +		{0x5795, 0x02},

> +		{0x57a1, 0x40},

In the existing 4-lanes tables the register addresses are kept in increasing order.
In the 2-lanes tables you've added in this patch this par is moved up breaking the sorting
by reg address order.
Otherwise these 13 registers settings are exactly the same for 2- and 4-lane configurations.

Also for the 3280x2464 resolution the V and H total sizes are the same in 2- and 4-lane
configurations.
But for the 1640x1232 resolution these settings are different in 2- and 4-lane configurations.
This looks like unnecessary change (which may worth a separate patch if there is a reason to
change these timings).

The rest of the ov8856_mode_lanes_regs[] registers are set to the same values in 2- and 4-lane
configurations.

All that said, does it make sense to add the two whole sets of register settings for the 2-lane
modes if switching between 2 and 4 lanes involves at most four registers (0x3018, 0x4837 for sure,
and probably 0x3614 and 0x3837)?

Thanks,
