Subject: [PATCH v4 0/9] phy: use syscon framework APIs to set ctrl mod reg

phy-omap-control driver was added when there was no proper
infrastructure for doing control module initializations. The
phy-omap-control driver is not an 'actual' PHY driver and it
was just a hack to do PHY related control module initializations.
phy-omap-control is also getting unmanageable with the number of
platforms each having number of modules (like USB, SATA, PCIe),
using the same driver for control module initializations.

Now with SYSCON framework being added to the kernel, phy-omap-control
shouldn't be needed and it also provides a uniform API across all the
modules to program the control module.

This series is basically to deprecate using phy-omap-control and use
syscon APIs to program the control module registers.

Changes from v3:
*) Added description of why syscon is better in cover letter
*) refactored some driver code so that it's easy to remove obsolete
   code when phy-omap-control driver is removed.

Changes from v2:
No changes.

Changes from v1:
*) cleanup ti_pipe3_probe in multiple steps
*) other minor cleanups

Changes from [1] in PHY patches include
*) cleanup ti_pipe3_probe
*) have mask, power_on and power_off values in usb_phy_data for
   omap-usb2 phy

The patches have been pushed to
	git://git.ti.com/linux-phy/linux-phy.git syscon_v4

[1] -> https://lkml.org/lkml/2015/6/23/189

All the testing was done both before applying the dt patches and after
applying the dt patches.

Kishon Vijay Abraham I (9):
  phy: ti-pipe3: introduce local struct device* in probe
  phy: ti-pipe3: move clk initialization to a separate function
  phy: ti-pipe3: move sysctrl initialization to a separate function
  phy: ti-pipe3: move mem resource initialization to a separate
    function
  phy: ti-pipe3: use ti_pipe3_power_off to power off the PHY during
    probe
  phy: ti-pipe3: use *syscon* framework API to power on/off the PHY
  phy: ti-pipe3: use *syscon* framework API to set PCS value of the PHY
  phy: omap-usb2: use omap_usb_power_off to power off the PHY during
    probe
  phy: omap-usb2: use *syscon* framework API to power on/off the PHY
