2020-04-30phy: qualcomm: usb-hs-28nm: Prepare clocks in initBjorn Andersson
The AHB clock must be on for qcom_snps_hsphy_init() to be able to write the initialization sequence to the hardware, so move the clock enablement to phy init and exit.

2020-03-20phy: qualcomm: Add Synopsys 28nm Hi-Speed USB PHY driverShawn Guo
Adds Qualcomm 28nm Hi-Speed USB PHY driver support. This PHY is usually paired with Synopsys DWC3 USB controllers on Qualcomm SoCs. The PHY can come in two flavours femtoPHY or picoPHY. This commit adds support for the femtoPHY with the possibility of extending to the picoPHY with additional future commits. Both PHYs are on a 28 nanometer process node. [bod: Updated qcom_snps_hsphy_set_mode to match new method signature Added disjunct on mode > 0 Removed regulator_set_voltage() in favour of setting floor in dts Removed 'snps' and from driver name Extended commit log to mention femtoPHY and picoPHY for future reference.] Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Cc: Andy Gross <agross@kernel.org> Cc: Bjorn Andersson <bjorn.andersson@linaro.org> Cc: Kishon Vijay Abraham I <kishon@ti.com> Cc: Philipp Zabel <p.zabel@pengutronix.de> Cc: Jorge Ramirez-Ortiz <jorge.ramirez.ortiz@gmail.com> Cc: linux-arm-msm@vger.kernel.org Cc: linux-kernel@vger.kernel.org Tested-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
