From: Srinidhi Kasagar Date: Fri, 19 Jun 2015 06:22:46 +0000 (+0530) Subject: PCI: Remove Intel Cherrytrail D3 delays X-Git-Tag: v4.3-rc1~145^2^3~17 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4a118753d411d3e22a463361bb867c51d63ebe14;p=platform%2Fkernel%2Flinux-exynos.git PCI: Remove Intel Cherrytrail D3 delays Just like Haswell, Intel Atom Cherrytrail does not need the default 10ms d3_delay imposed by the PCI specification. Expand quirk_remove_d3_delay() to apply to Cherrytrail devices, so we can ignore the 10ms delay before entering or exiting D3 suspend.
