Subject: dra7xx pci driver broken on dra7xx-evm
Date: Wed, 6 Jan 2016 22:45:18 +0100 [thread overview]
Message-ID: <20160106214518.GA6106@localhost.localdomain> (raw)
The dra7xx-evm box freezes hard at the very first PCI bus access, the
call to in dra7xx_pcie_readl() in dra7xx_pcie_probe().
The out-of-tree 3.14.53 TI driver performs a reset via platform data,
calling omap_device_assert_hardreset() by hook and crook.
Adding the reset into the mainline driver cures the freeze.
Question: How on earth is this driver supposed to work?
Thanks,
Richard
