No, it has nothing to do with the TLB.
Unable to handle kernel paging request at virtual address c2802174
pgd = c0004000
[c2802174] *pgd=21805811, *pte=00000000, *ppte=00000000
Internal error: Oops: 7 [#1] PREEMPT ARM
The number after the Oops: is the FSR value, which means "page translation
fault", and sure enough, the pgd/pte values show that there is no page
table entry at the faulting address.
That's odd, because ioremap() aligns the size of the requested mapping up
to a multiple of the page size, and inserts page table entries according
to the rounded size.
Where are you calling ioremap(), iounmap() etc? IOW, please show your
code for this.
I also notice that the unwinder failed to unwind the complete backtrace:
[<c02bcb38>] (clk_gate_is_enabled) from [<c02b9a0c>] (clk_disable_unused_subtree+)
[<c02b9a0c>] (clk_disable_unused_subtree) from [<c02b99c8>] (clk_disable_unused_s)
which is really annoying. Maybe turning frame pointers on will get is a
proper backtrace, though I don't think it's that important to this bug.
