This is a note to let you know that I've just added the patch titled ARM: pxa: fix dm9000 platform data regression to the 4.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-pxa-fix-dm9000-platform-data-regression.patch and it can be found in the queue-4.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From a927ef895e288e79f1bfed221f27d7bfa37e907f Mon Sep 17 00:00:00 2001 From: Robert Jarzmik <robert.jarzmik@xxxxxxx> Date: Sat, 11 Jul 2015 21:33:06 +0200 Subject: ARM: pxa: fix dm9000 platform data regression From: Robert Jarzmik <robert.jarzmik@xxxxxxx> commit a927ef895e288e79f1bfed221f27d7bfa37e907f upstream. Since dm9000 driver added support for a vcc regulator, platform data based platforms have their ethernet broken, as the regulator claiming returns -EPROBE_DEFER and prevents dm9000 loading. This patch fixes this for all pxa boards using dm9000, by using the specific regulator_has_full_constraints() function. This was discovered and tested on the cm-x300 board.
