This patchset adds support for USB for Qualcomm SM8550 platform.
This patchset is based on top of the following patchset:
[1] https://lore.kernel.org/all/20230208180020.2761766-1-abel.vesa@linaro.org/
Changes since v5:
* rebased on top of [1]
Changes since v4:
* dropped the dts/dtsi patches as there is no change needed to what is
already merged
* rebased on top of next-20230206 which has Luca's patches for SM6350,
like Johan suggested

The SM8550 SoC uses Synopsis eUSB2 PHY for USB 2.0.
Add a new driver for it.
The driver is based on a downstream implementation.

The v5 version of this patch was here:
https://lore.kernel.org/all/20230207114024.944314-3-abel.vesa@linaro.org/
Changes since v5:
* fixed checkpatch indentation warning for ref_clk_freq argument on
"unsupported ref_clk_freq" error
Changes since v4:
* none
Changes since v3:
* none
Changes since v2:
* this time actually dropped the qcom_snps_, which I missed in the v2
* this time actually added the new lines after break in switch clause,
as Vinod suggested, which I missed in the v2
Changes since v1:
* replaced qualcomm with qcom in subject line
* dropped all unnecessary includes
* dropped qcom_snps prefix from qcom_snps_eusb2_hsphy_vreg_names
* properly aligned the arguments for qcom_snps_eusb2_hsphy_write_mask
* added empty lines after break in switch clause, like Vinod suggested

The SM8550 SoC uses Synopsis eUSB2 PHY for USB 2.0.
Add a new driver for it.
The driver is based on a downstream implementation.
Signed-off-by: Abel Vesa <abel.vesa@linaro.org>

The v5 version of this patch was here:
https://lore.kernel.org/all/20230207114024.944314-3-abel.vesa@linaro.org/
Changes since v5:
* fixed checkpatch indentation warning for ref_clk_freq argument on
"unsupported ref_clk_freq" error
Changes since v4:
* none
Changes since v3:
* none
Changes since v2:
* this time actually dropped the qcom_snps_, which I missed in the v2
* this time actually added the new lines after break in switch clause,
as Vinod suggested, which I missed in the v2
Changes since v1:
* replaced qualcomm with qcom in subject line
* dropped all unnecessary includes
* dropped qcom_snps prefix from qcom_snps_eusb2_hsphy_vreg_names
* properly aligned the arguments for qcom_snps_eusb2_hsphy_write_mask
* added empty lines after break in switch clause, like Vinod suggested

The v5 version of this patch was here:
https://lore.kernel.org/all/20230207114024.944314-7-abel.vesa@linaro.org/
Changes since v5:
* added Johan's R-b tag
Changes since v4:
* rebased on next-20230206 which includes Luca's SM6350 phy patches,
like Johan suggested
* added missing usage of com_resetm_ctrl_reg, com_c_ready_status_reg
and dp_phy_status_reg
* dropped the .dp_tx0 and .dp_tx1 for v5 offsets changes
Changes since v3:
* switched dp_tx and dp_tx2 to off->dp_tx0 and off->dp_tx1, like Neil
suggested
Changes since v2:
* none

Add SM8550 specific register layout and table configs.
Signed-off-by: Abel Vesa <abel.vesa@linaro.org>

The v5 version of this patch was here:
https://lore.kernel.org/all/20230207114024.944314-7-abel.vesa@linaro.org/
Changes since v5:
* added Johan's R-b tag
Changes since v4:
* rebased on next-20230206 which includes Luca's SM6350 phy patches,
like Johan suggested
* added missing usage of com_resetm_ctrl_reg, com_c_ready_status_reg
and dp_phy_status_reg
* dropped the .dp_tx0 and .dp_tx1 for v5 offsets changes
Changes since v3:
* switched dp_tx and dp_tx2 to off->dp_tx0 and off->dp_tx1, like Neil
suggested
Changes since v2:
* none
