| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Berlin SoC has a two SATA ports. Add a PHY driver to handle them. The mode selection can let us think this PHY can be configured to fit other purposes. But there are reasons to think the SATA mode will be the only one usable: the PHY registers are only accessible indirectly through two registers in the SATA range, the PHY seems to be integrated and no information tells us the contrary. For these reasons, make the driver a SATA PHY driver. Signed-off-by: Antoine Ténart <antoine.tenart@free-electrons.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

* phy: fix kernel oops in phy_lookup()Sergei Shtylyov2014-04-241-0/+3
| | | | | | | | | | | | The kernel oopses in phy_lookup() due to 'phy->init_data' being NULL if we register PHYs from a device tree probing driver and then call phy_get() on a device that has no representation in the device tree (e.g. a PCI device). Checking the pointer before dereferening it and skipping an interation if it's NULL prevents this kernel oops.

* phy: restore OMAP_CONTROL_PHY dependenciesJean Delvare2014-04-241-0/+1
| | | | | | | | | | | | | When OMAP_CONTROL_USB was renamed to OMAP_CONTROL_PHY (commit 14da699b), its dependencies were lost in the process. Nothing in the commit message indicates that this removal was intentional, so I think it was by accident and the dependencies should be restored.

* phy: exynos: fix building as a moduleArnd Bergmann2014-04-241-4/+5
| | | | | | | | | | | | | | | The top-level phy-samsung-usb2 driver may be configured as a loadable module, which currently causes link errors because of the dependency on the exynos{5250,4x12,4210}_usb2_phy_config symbol. Solving this could be achieved by exporting these symbols, but as the SoC-specific parts of the driver are not currently built as modules, it seems better to just link everything into one module and avoid the need for the export.

The DPLL will be enabled in .init() and idled in .exit(). Don't reprogram the DPLL if it has been already locked by the bootloader. This fixes a problem with SATA, where it fails if SATA was used by the bootloader. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
