2021-01-19dt-bindings: phy: qcom,usb-snps-femto-v2: Add SM8250 and SM8350 bindingsJack Pham1-0/+2
Add the compatible strings for the USB2 PHYs found on QCOM SM8250 & SM8350 SoCs. Note that the SM8250 compatible is already in use in the dts and driver implementation but was missing from the documentation.

2021-01-19phy: qcom-qmp: Add SM8350 USB QMP PHYsJack Pham2-0/+312
Add support for the USB DP & UNI PHYs found on SM8350. These use version 5.0.0 of the QMP PHY IP and thus require new "V5" definitions of the register offset macros for the QSERDES RX and TX blocks. The QSERDES common and QPHY PCS blocks' register offsets are largely unchanged from V4 so some of the existing macros can be reused.

2021-01-13phy: stm32: rework PLL Lock detectionAmelie Delaunay1-34/+54
USBPHYC has a register per phy to control and monitor the debug interface of the HS PHY through a digital debug access. With this register, it is possible to know if PLL Lock input to phy is high. That means the PLL is ready for HS operation. Instead of using an hard-coded delay after PLL enable and PLL disable, use this bit to ensure good operating of the HS PHY. Also use an atomic counter (n_pll_cons) to count the actual number of PLL consumers and get rid of stm32_usbphyc_has_one_phy_active. The boolean active in the usbphyc_phy structure is kept, because we need to know in remove if a phy_exit is required to properly disable the PLL.

2020-12-27proc mountinfo: make splice available againLinus Torvalds1-3/+6
Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.

The fix is to move Tegra's link up handling to .start_link() function like other DWC drivers. Tegra is a bit more complicated than others as it re-inits the whole DWC controller to retry the link.

2020-12-26drm/amd/display: avoid uninitialized variable warningLinus Torvalds1-1/+1
clang (quite rightly) complains fairly loudly about the newly added mpc1_get_mpc_out_mux() function returning an uninitialized value if the 'opp_id' checks don't pass. This may not happen in practice, but the code really shouldn't return garbage if the sanity checks don't pass. So just initialize 'val' to zero to avoid the issue.

2020-12-25genirq: Fix export of irq_to_desc() for powerpc KVMMichael Ellerman1-1/+1
Commit 64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()") removed the export of irq_to_desc() unless powerpc KVM is being built, because there is still a use of irq_to_desc() in modular code there. However it used: #ifdef CONFIG_KVM_BOOK3S_64_HV Which doesn't work when that symbol is =m, leading to a build failure: ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined! Fix it by checking for the definedness of the correct symbol which is CONFIG_KVM_BOOK3S_64_HV_MODULE.
