Hello again,
I added debug prints to tc358743_probe_of and
tc358743_num_csi_lanes_needed, tracking the values of pll_prd and pll_fbd.
I believe the bug is caused by probe returning early when it encounters
an unsupported datarate of more than 1gbps per lane, which skips the
code that would initialize pll_fbd.
Hence later in tc358743_num_csi_lanes_needed, pll_fbd is zero - leading
to divide by zero.
The interesting parts of dmesg leading to this conclusion:
[ 16.393072] imx6_mipi_csi2: module is from the staging directory, the
quality is unknown, you have been warned.
[ 16.891557] tc358743 0-000f: initialized pll_prd = 4

I don't really know where this condition should be checked for, or
avoided. Hopefully though this gives somebody else enough information to
find a solution.

Dear Maintainers,

I am attaching the device-tree changes as a file for reference. Any
ideas what is happening here?
I can see 2 divisions:
1. pdata->refclk_hz / pdata->pll_prd
2. DIV_ROUND_UP(bps, bps_pr_lane)
1. should never be 0, since it is initialized during probe and then
never changed
2. see how the divisor can be 0
pdata->refclk_hz / pdata->pll_prd is the inversion of how pll_prd is
calculated, and should equal to 6MHz from probe.
pll_fbd is also set in probe: pll_fbd = bps_pr_lane / refclk_hz * pll_prd
As I have specified a link-frequency of 594MHz, that produces:
bps_pr_lane = 2 * 594MHz
pll_fbd = 2 * 594MHz / 27MHz * (27MHz / 6MHz) = 2 * 594MHz / 6MHz = 198
Apparently from initialization, the division by zero can not occur :(
(unless I made a mistake here).
Thank you for reading this far!
Yours sincerely
