Variable delay is being assigned to zero and the code falls through to
the next case in a switch statement that returns out of the function.
The variable is never read in this scenario and so the assignment is
redundant and can be removed.

Add support for PHY_INTERFACE_MODE_5GBASER mode within the Marvell CP110
common PHY driver.
This is currently only supported via SMC calls to TF-A. Legacy support
may be added later, if needed.

Many recent Qualcomm platforms comes with native DP and eDP support.
This consists of a controller in the MDSS and a QMP-like PHY.
While similar to the well known QMP block, the eDP PHY only has TX lanes
and the programming sequences are slightly different. Rather than
continuing the trend of parameterize the QMP driver to pieces, this
introduces the support as a new driver.
The registration of link and pixel clocks are borrowed from the QMP
driver. The non-DP link frequencies are omitted for now.
The eDP PHY is very similar to the dedicated (non-USB) DP PHY, but only
the prior is supported for now.

Pull char/misc driver updates from Greg KH:
"Here is the big set of char and misc and other tiny driver subsystem
updates for 5.16-rc1.
Loads of things in here, all of which have been in linux-next for a
while with no reported problems (except for one called out below.)
Included are:
- habanana labs driver updates, including dma_buf usage, reviewed and
acked by the dma_buf maintainers
- iio driver update (going through this tree not staging as they
really do not belong going through that tree anymore)
- counter driver updates
- hwmon driver updates that the counter drivers needed, acked by the
hwmon maintainer
- xillybus driver updates
- binder driver updates
- extcon driver updates
- dma_buf module namespaces added (will cause a build error in arm64
for allmodconfig, but that change is on its way through the drm
tree)
- lkdtm driver updates
- pvpanic driver updates
- phy driver updates
- virt acrn and nitr_enclaves driver updates
- smaller char and misc driver updates"

The FSEL_MASK which selects the refclock is defined incorrectly.
It should be [4:6] not [5:7]. Due to this incorrect definition, the BIT(7)
in USB2_PHY_USB_PHY_HS_PHY_CTRL_COMMON0 is reset which keeps PHY analog
blocks ON during suspend.
Fix this issue by correctly defining the FSEL_MASK.

Commit f839f14e24 ("phy: qcom-qmp: Add sc8180x PCIe support") added
SC8180X PCIe tables, but used sm8250_qmp_pcie_serdes_tbl as a serdes
table because of the copy paste error. Commit bfccd9a71a ("phy:
qcom-qmp: Fix sc8180x PCIe definition") corrected part of this mistake
by pointing serdes_tbl to sc8180x_qmp_pcie_serdes_tbl, however the
serdes_tbl_num field was not updated to use sc8180x table. So let's now
fix the serdes_tbl_num field too.

Add support to output received reference clock. Model the received

clock. When received refclk is selected to output on cmn_refclk_p/m,
this is the internal reference clock driven on the pma_cmn_refclk_int.

implementation by modelling reference clock driver as a "clock" with
derived reference clock set as its default parent. The support for

It can be necessary to adjust the phys settings to compensate parasitics.
This patch adds support of new optional properties to configure the tune
interface of the phys of stm32-usbphyc.
Properties are optional, that's why each property is skipped if not
found (-EINVAL).
Phy tuning is restored on resume because if deep low power state is
achieved, phy tuning configuration is reset.
