2019 -0800 # # phy: fix build breakage: add PHY_MODE_SATA # # Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses # the PHY_MODE_SATA, but that enum had not yet been added. This caused a # build failure for me, with today's linux.git. # # Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding # in the Marvell Berlin SATA PHY driver. # # Fix the build by: # # 1) Renaming Marvell's defined value to a more scoped name, # in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA. # # 2) Adding the missing enum, which was going to be added anyway as part # of [1]. # # [1] https://lkml.kernel.org/r/20190108163124.6409-3-miquel.raynal@bootlin.com # # Fixes: 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") # # Signed-off-by: John
