phy: Constify struct phy_ops variables

2015-08-03T13:05:09+00:00

The phy_ops variables are never modified after initialized in these drivers, so make them const. Signed-off-by: Axel Lin Acked-by: Patrice Chotard Signed-off-by: Kishon Vijay Abraham I

phy: ti-pipe3: i783 workaround for SATA lockup after dpll unlock/relock

2015-08-01T10:22:58+00:00

SATA_PLL_SOFT_RESET bit of CTRL_CORE_SMA_SW_0 must be toggled between a SATA DPLL unlock and re-lock to prevent SATA lockup. Introduce a new DT parameter 'syscon-pllreset' to provide the syscon regmap access to this register which sits in the control module. If the register is not provided we fallback to the old behaviour i.e. SATA DPLL refclk will not be disabled and we prevent SoC low power states.

phy: ti-pipe3: fix suspend

2015-07-15T14:32:09+00:00

Relying on PM-ops for shutting down PHY clocks was a bad idea since the users (e.g. PCIe/SATA) might not have been suspended by then. The main culprit for not shutting down the clocks was the stray pm_runtime_get() call in probe. Fix the whole thing in the right way by getting rid of that pm_runtime_get() call from probe and removing all PM-ops. It is the sole responsibility of the PHY user to properly turn OFF and de-initialize the PHY as part of its suspend routine. As PHY core serializes init/exit we don't need to use a spinlock in this driver. So get rid of it. Signed-off-by: Roger Quadros Signed-off-by: Sekhar Nori Signed-off-by: Kishon Vijay Abraham I

if !CONFIG_OF, the probe fails. This is a dt-only driver, so the ifdef CONFIG_OF guard and of_match_ptr are not needed. Signed-off-by: Axel Lin Signed-off-by: Kishon Vijay Abraham I

phy: ti-pipe3: Fix SATA across suspend/resume

2015-01-21T09:53:06+00:00

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

2015-01-21T09:53:06+00:00

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. Reported-by: Nishant Menon Signed-off-by: Roger Quadros Signed-off-by: Kishon Vijay Abraham I
