      phy: fix return value check in armada375_usb_phy_probe() · 147fd9d6
      由 Wei Yongjun 提交于 
      In case of error, the function devm_ioremap_resource() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().

      phy: ti-pipe3: Fix SATA across suspend/resume · 7f33912d
      由 Roger Quadros 提交于 
      Failed test case: Boot without SATA drive connected. Suspend/resume
the board and then connect SATA drive. It fails to enumerate.

Due to Errata i783 "SATA Lockup After SATA DPLL Unlock/Relock"
we can't allow SATA DPLL to be in the unlocked state.
The SATA refclk (sata_ref_clk) is the source of the SATA_DPLL.
This clock is being controlled only by the AHCI SATA driver and is
shut off during system suspend (if the SATA drive was not already attached)
causing the SATA DPLL to be unlocked and so causing errata i783.

To prevent sata_ref_clk from being disabled, we add the control of
this clock to the SATA PHY driver and prevent it from being disabled.

This also fixes the issue of SATA not working on OMAP5/DRA7 when
AHCI platform driver is built as a module.

NOTE: Device tree changes also required for OMAP5 & DRA7.

      phy: ti-pipe3: Disable clocks on system suspend · 6e738432
      由 Roger Quadros 提交于 
      On system suspend, the runtime_suspend() driver hook doesn't get
called for USB phy and so the clocks are not disabled in the driver.
This causes the L3INIT_960M_GFCLK and L3INIT_480M_GFCLK to remain
active on the DRA7 platform while in system suspend.

In case of pcie-phy, the runtime_suspend hook gets called after
the suspend hook so we introduce a flag phy->enabled to keep
track if our clocks are enabled or not to prevent multiple
enable/disables.

Add suspend/resume hooks to the driver.
Move enabling/disabling clock code into helper functions.

      Revert "clk: ppc-corenet: Fix Section mismatch warning" · 176a107b
      由 Kevin Hao 提交于 
      This reverts commit da788acb.

That commit tried to fix the section mismatch warning by moving the
ppc_corenet_clk_driver struct to init section. This is definitely wrong
because the kernel would free the memories occupied by this struct
after boot while this driver is still registered in the driver core.
The kernel would panic when accessing this driver struct.

      Lockdep reported a possible deadlock between the cpuclk lock and for example

                               lock(clk_lock);
  <Interrupt>
    lock(&(&i2c->lock)->rlock);

 *** DEADLOCK ***

The generic clock-types of the core ccf already use spin_lock_irqsave when
touching clock registers, so do the same for the cpuclk.
