phy: Group vendor specific phy drivers

2017-06-01T09:58:33Z

Adding vendor specific directories in phy to group phy drivers under their respective vendor umbrella. Also updated the MAINTAINERS file to reflect the correct directory structure for phy drivers.

phy: qcom-ufs: Fix misplaced jump label

2017-01-27T08:29:13Z

We want to skip only tx/rx_iface clocks and not ref_clk_src as well. Fix the jump label accordingly.

phy: qcom-ufs: Remove -always-on property

2017-01-27T07:36:52Z

The fact that a regulator is always-on is a property of the regulator, not a specific consumer. Implementing this in the driver leads to a system behaviour that is dependent on if the Qualcomm UFS PHY was ever (partially) probed. If the specific regulator should be always on in a particular device, mark it so by specifying "regulator-always-on" in the regulator node.

phy: qcom-ufs: Correct usage of regulator_get()

2017-01-27T07:36:52Z

When regulator_get() tries to resolve a regulator supply but fail to find a matching property in DeviceTree it returns a dummy regulator, if a matching supply is specified but unavailable the regulator core will return an error. Based on this we should not ignore errors upon failing to acquire the optional "vddp-ref-clk" supply.

phy: qcom-ufs: Don't kfree devres resource

2017-01-27T07:36:52Z

Upon failing to acquire regulator supplies the qcom-ufs driver calls kfree() on the devm allocated memory used to store the name of the regulator, leading to devres corruption. Rather than switching to using the appropriate free function the patch acknowledge the fact that "name" is always a constant string and we don't actually need to create a local copy of it, but rather just reference the constant string.

phy: qcom-ufs: Remove common layer phy exit callback

2016-11-08T23:05:45Z

The common layer phy exit callback ufs_qcom_phy_exit() calls phy_power_off() that has no meaning when phy_power_off() callback is already registered with the phy provider and the consumer makes use of the same. Instead, add a no-op specific phy_exit() callback for now to add the exit sequence at a later point. Signed-off-by: Vivek Gautam Reviewed-by: Subhash Jadavani Signed-off-by: Martin K. Petersen

phy: qcom-ufs-qmp-xx: Discard remove callback for drivers.

2016-11-08T23:05:45Z

remove() callback does a phy_power_off() only over the phy, and nothing else now. The phy_power_off() over the generic phy is called from the phy consumer, and phy provider driver should not explicitly need to call any phy ops. So discard the remove callback for qcom-ufs phy platform drivers. Signed-off-by: Vivek Gautam Reviewed-by: Subhash Jadavani Signed-off-by: Martin K. Petersen
