MIPS: ralink: enable PCI support only if driver for mt7621 SoC is selected

2019-11-14T05:09:37+00:00

Some versions of SoC MT7621 have three PCI express hosts. Some boards make use of those PCI through the staging driver mt7621-pci. Recently PCI support has been removed from MT7621 Soc kernel configuration due to a build error. This makes imposible to compile staging driver and produces a regression for gnubee based boards. Enable support for PCI again but enable it only if staging mt7621-pci driver is selected.

staging: mt7621-pci: add quirks for 'E2' revision using 'soc_device_attribute'

2019-10-07T10:25:47+00:00

Depending on revision of the chip, reset lines are inverted. Make code more readable making use of 'soc_device_match' in driver probe function. Signed-off-by: Sergio Paracuellos Link: https://lore.kernel.org/r/20191006181032.19112-1-sergio.paracuellos@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: mt7621-pci: avoid use 'err' local variable

2019-07-25T07:58:26+00:00

Function 'mt7621_pcie_request_resources' is using 'err' local variable to get value returned from 'devm_request_pci_bus_resources' and returning after that. This is not needed at all. Instead of that just directly return returned value by the function which is also returning zero on success.

staging: mt7621-pci: Add of_node_put() before return

2019-07-22T05:34:15+00:00

Each iteration of for_each_available_child_of_node puts the previous node, but in the case of a return from the middle of the loop, there is no put, thus causing a memory leak. Hence add an of_node_put before the return in two places. Issue found with Coccinelle.

staging: mt7621-pci: fix PCIE_FTS_NUM_LO macro

2019-07-01T06:58:21+00:00

Add missing parenthesis to PCIE_FTS_NUM_LO macro to do the same it was being done in original code. Fixes: a4b2eb912bb1 ("staging: mt7621-pci: rewrite RC FTS configuration") Signed-off-by: Sergio Paracuellos Cc: stable Signed-off-by: Greg Kroah-Hartman

staging: mt7621-pci: use 'module_init' instead of 'arch_initcall'

2019-06-21T14:50:10+00:00

This driver has dependencies on mt7621-gpio and mt7621-pci-phy which are init in later stages. Hence, when this driver is probed it is always returning 'EPROBE_DEFER' and being initialized afterwards. Use function 'module_init' to just initialize later.

staging: mt7621-pci: add phy exit call if phy_power_on call fails

2019-06-21T14:50:10+00:00

Add missing call to 'phy_exit' function if the phy_power_on call fails. With this call added the error path is properly handled. Fixes: 07420a02b003 ("staging: mt7621-pci: use gpio perst instead of builtin behaviour") Signed-off-by: Sergio Paracuellos Signed-off-by: Greg Kroah-Hartman

staging: mt7621-pci: disable pcie port clock if there is no pcie link

2019-06-21T14:50:10+00:00

When there is no pcie link detected we have to properly disable the port pcie clock. Signed-off-by: Sergio Paracuellos Signed-off-by: Greg Kroah-Hartman

staging: mt7621-pci: dt-bindings: add perst-gpio to sample bindings

Both driver and device tree have been updated to use GPIO perst. Update bindings documentation also. Signed-off-by: Sergio Paracuellos Signed-off-by: Greg Kroah-Hartman

staging: mt7621-pci: use gpio perst instead of builtin behaviour

2019-06-20T12:45:49+00:00

Some boards seems to ignore the PERST builtin behaviour to properly perform a pcie line reset. Use gpio PERST behaviour instead which seems to be more common.
