Unfortunately PCIe Exynos driver is in poor shape, really poor. This would explain that maybe it's better to have new driver instead of merging them, especially that hardware is different. Although I am still waiting for some description of these differences... I said that Exynos PCIe looks poor... but what is worse, it looks like you based on it so you copied or some bad patterns it had. Except this the driver has several coding style issues, so please be sure to run checkpatch, sparse and smatch before sending it. Please work on this driver to make it close to Linux coding style, so there will be no need for us, reviewers, focus on basic stuff. Optionally, send all this to staging. :) Best regards, Krzysztof
