From mboxrd@z Thu Jan 1 00:00:00 1970 From: swarren@wwwdotorg.org (Stephen Warren) Date: Fri, 22 Aug 2014 15:18:28 -0600 Subject: [PATCH] ARM: tegra: add PCIe-related pins to the Jetson TK1 pinmux tables Message-ID: <1408742308-18004-1-git-send-email-swarren@wwwdotorg.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Stephen Warren This pinmux tables currently omit any configuration for PCIe clk_req, wake, and rst pins, which in turn causes intermittent failures in U-Boot's PCIe support. Import an updated version of the pinmux tables which rectifies this. (While I'm still hoping to remove the pinmux tables from DTs for Tegra124+ devices, while they're still here, they may as well be complete and correct).
