Patches were tested on to of TI -RT tree ti-rt-linux-4.1.y. -------- Forwarded Message -------- Subject: Re: [PATCH 0/7] gpio: omap: fixes and improvements Date: Fri, 4 Sep 2015 21:42:03 +0000 From: Austin Schuh To: grygorii.strashko@ti.com CC: Philipp Schrader Hi Grygorii, We are running the entire patchset on top of a7a6541db840cc4514a26fc12cc1bc94d1b9e873 from the git:// git.ti.com/ti-linux-kernel/ti-linux-kernel.git tree. I've pushed the system pretty hard overnight and haven't seen any instability (with lockdep enabled. We used to get splats pretty fast). I wasn't on lkml when you sent the patchset out, so I'm not sure how to best reply to the original thread with this info. Tested-by: Austin Schuh Austin -------- Forwarded Message -------- -- regards, -grygorii
