Subject: [PATCH 0/2] Fix no_console_suspend in the 8250_omap driver

This series fixes the no_console_suspend in the 8250_omap driver.
A first implementation was introducted [1].
But it was recently reverted [2] because it causes a crash during suspend on
the platforms that don't use PM domains.
This series implements the proposal sent by Théo Lebrun and discussed with
Kevin Hilman and Tony Lindgren in the thread [3].

This series was tested on a J7200 EVM board.

Regards,

Thomas
