2017-12-26dt-bindings: Use lower case hex in unit-addressesRob Herring
DT unit addresses should be lower case hex. Fix all the binding examples. Converted with the following command from Krzysztof Kozlowski: sed -e 's/@\([a-fA-F0-9_-]*\) {/@\L\1 {/' -i $(find Documentation/devicetree/bindings -name '*.txt') Signed-off-by: Rob Herring <robh@kernel.org>
2016-09-10dt-bindings: phy: ti: add documentation for ti,dra7x-usb2Sekhar Nori
Commit 7e472402ca30 ("phy: omap-usb2: Provide workaround for USB2PHY false disconnect") added a new binding for USB2 PHYs on DRA7x. But it has remained undocumented so far. Add documentation for the binding.

2015-12-21phy: omap-usb2: use *syscon* framework API to power on/off the PHYKishon Vijay Abraham I
Deprecate using phy-omap-control driver to power on/off the PHY, and use *syscon* framework to do the same. This handles powering on/off the PHY for the USB2 PHYs used in various TI SoCs. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2015-08-01phy: ti-pipe3: i783 workaround for SATA lockup after dpll unlock/relockRoger Quadros
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.

2014-07-22phy: pipe3: insert delay to enumerate in GEN2 modeKishon Vijay Abraham I
8-bit delay value (0xF1) is required for GEN2 devices to be enumerated consistently. Added an API to be called from PHY drivers to set this delay value and called it from PIPE3 driver to set the delay value.

2014-07-22phy: phy-omap-pipe3: Add support for PCIe PHYKishon Vijay Abraham I
PCIe PHY uses an external pll instead of the internal pll used by SATA and USB3. So added support in pipe3 PHY to use external pll. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Reviewed-by: Roger Quadros <rogerq@ti.com>
