Lee, Doug,
I've bisected a boot failure on Tegra Dalmore (which has a tps65090)
down to this patch. It started in -next 0501, so I guess Lee might
have pushed some patches out now even though the commit date is a
little while back?
The commit is:
commit 60e91b51b515b20f85697fcd397911fdb97bbdca

regulator: tps65090: Allow setting the overcurrent wait time
The tps65090 regulator allows you to specify how long you want it to
wait before detecting an overcurrent condition. Allow specifying that
through the device tree (or through platform data).

Panic is line 309:
303 for (num = 0; num < TPS65090_REGULATOR_MAX; num++) {
304 tps_pdata = tps65090_pdata->reg_pdata[num];
305
306 ri = &pmic[num];
307 ri->dev = &pdev->dev;
308 ri->desc = &tps65090_regulator_desc[num];
309 ri->overcurrent_wait_valid =
tps_pdata->overcurrent_wait_valid;
310 ri->overcurrent_wait = tps_pdata->overcurrent_wait;
so it looks like tps_pdata is NULL. Should likely be a check for it?
