-Subject: [PATCH] Revert "bcma: init serial console directly from ChipCommon
- code"
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reverts commit 4c81acab3816 ("bcma: init serial console directly
-from ChipCommon code") as it broke IRQ assignment. Getting IRQ with
-bcma_core_irq helper on SoC requires MIPS core to be set. It happens
-*after* ChipCommon initialization so we can't do this so early.
-
-This fixes a user reported regression. It wasn't critical as serial was
-still somehow working but lack of IRQs was making in unreliable.

-Fixes: 4c81acab3816 ("bcma: init serial console directly from ChipCommon code")
-Reported-by: Felix Fietkau <nbd@nbd.name>
-Cc: stable@vger.kernel.org # 4.6+
