From 9cb3985af63555810bb07de50acdf4170771451d Mon Sep 17 00:00:00 2001 From: Yicong Yang Date: Mon, 17 Feb 2020 19:12:55 +0800 Subject: [PATCH] PCI: Add 32 GT/s decoding in some macros Link speed 32.0 GT/s is supported in PCIe r5.0. Add this speed to PCIE_SPEED2STR() and PCIE_SPEED2MBS_ENC() to correctly decode it. This is complementary to de76cda215d5 ("PCI: Decode PCIe 32 GT/s link speed").
