ec939e4c94 ARM: SoC-related driver updates
Various driver updates for platforms:
 
  - A larger set of work on Tegra 2/3 around memory controller and
  regulator features, some fuse cleanups, etc..
 
  - MMP platform drivers, in particular for USB PHY, and other smaller
  additions.
 
  - Samsung Exynos 5422 driver for DMC (dynamic memory configuration),
  and ASV (adaptive voltage), allowing the platform to run at more
  optimal operating points.
 
  - Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas
 
  - Clock/reset control driver for TI/OMAP
 
  - Meson-A1 reset controller support

64f86b9978 phy: qcom-usb-hs: Fix extcon double register after power cycle
Commit f0b5c2c963 ("phy: qcom-usb-hs: Replace the extcon API")
switched from extcon_register_notifier() to the resource-managed
API, i.e. devm_extcon_register_notifier().

This is problematic in this case, because the extcon notifier
is dynamically registered/unregistered whenever the PHY is powered
on/off. The resource-managed API does not unregister the notifier
until the driver is removed, so as soon as the PHY is power cycled,
attempting to register the notifier again results in:

	double register detected
	WARNING: CPU: 1 PID: 182 at kernel/notifier.c:26 notifier_chain_register+0x74/0xa0
	Call trace:
	 ...
	 extcon_register_notifier+0x74/0xb8
	 devm_extcon_register_notifier+0x54/0xb8
	 qcom_usb_hs_phy_power_on+0x1fc/0x208
	 ...

... and USB stops working after plugging the cable out and in
another time.

The easiest way to fix this is to make a partial revert of
commit f0b5c2c963 ("phy: qcom-usb-hs: Replace the extcon API")
and avoid using the resource-managed API in this case.

a703d279c5 We have a small collection of core framework updates this time, mostly around
clk registration by clk providers and debugfs "nice to haves" for rate
 constraints. I'll highlight that we're now setting the clk_init_data pointer
 inside struct clk_hw to NULL during clk_register(), which may break some
 drivers that thought they could use that pointer during normal operations. That
 change has been sitting in next for a while now but maybe something is still
 broken. We'l see. Other than that the core framework changes aren't invasive
 and they're fixing bugs, simplifying, and making things better.
 
 On the clk driver side we got the usual addition of new SoC support, new
 features for existing drivers, and bug fixes scattered throughout. The biggest
 diffstat is the Amlogic driver that gained CPU clk support in addition to
 migrating to the new way of specifying clk parents. After that the Qualcomm,
 i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
 clock controllers from those vendors.
 
 Core:
  - Drop NULL checks in clk debugfs
  - Add min/max rates to clk debugfs
  - Set clk_init_data pointer inside clk_hw to NULL after registration
  - Make clk_bulk_get_all() return an 'id' corresponding to clock-names
  - Evict parents from parent cache when they're unregistered
 
 New Drivers:
  - Add clock driver for i.MX8MN SoCs
  - Support aspeed AST2600 SoCs
  - Support for Mediatek MT6779 SoCs
  - Support qcom SM8150 GCC and RPMh clks
  - Support qcom QCS404 WCSS clks
  - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
  - Addition of clock driver for Rockchip rk3308 SoCs
 
 Updates:
  - Add regulator support to the cdce925 clk driver
  - Add support for Raspberry Pi 4 bcm2711 SoCs
  - Add SDIO gate support to aspeed driver
  - Add missing of_node_put() calls in various clk drivers
  - Migrate Amlogic driver to new clock parent description method
  - Add DVFS support to Amlogic Meson g12
  - Add Amlogic Meson g12a reset support to the axg audio clock controller
  - Add sm1 support to the Amlogic Meson g12a clock controller
  - Switch i.MX8MM clock driver to platform driver
  - Add Hifi4 DSP related clocks for i.MX8QXP SoC
  - Fix Audio PLL setting and parent clock for USB
  - Misc i.MX8 clock driver improvements and corrections
  - Set floor ops for Qualcomm SD clks so that rounding works
  - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1

7f7378618b power: supply: cpcap-charger: Enable vbus boost voltage
We are currently not enabling VBUS boost for cpcap when in host mode.
This means the VBUS is fed at the battery voltage level, which can cause
flakeyness enumerating devices.

Looks like the boost control for VBUS is CPCAP_BIT_VBUS_SWITCH that we
must enable in the charger for nice 4.92 V VBUS output. And looks like
we must not use the STBY pin enabling but must instead use manual VBUS
control in phy-cpcap-usb.

We want to do this in cpcap_charger_vbus_work() and also set a flag for
feeding_vbus to avoid races between USB detection and charger detection,
and disable charging if feeding_vbus is set.

Now that all COMPHY modes are supported by the driver, update the
comment stating that mvebu_comphy_power_off() should be called for
each lane. This is still wrong because for compatibility reasons, it
might break users running an old firmware (the driver only uses SMC

There is no public clock tree that implies such dependencies between
the MG/MG-core/AXI clocks and the COMPHY IP but accessing the COMPHY
registers while one of the three clocks are disabled stalls the CPU.

This happens if, for instance, the COMPHY driver probe is deferred
(eg. the USB Vbus regulator driver is not yet visible). The MVPP2
driver which also needs these clocks (among others) will
prepare/enable the clocks, then be deferred, and disable/unprepare
them. Next COMPHY lane to be configured would produce an infinite
stall.

14ced7e3a1 phy: qcom-qmp: Correct ready status, again
Despite extensive testing of commit 885bd76596 ("phy: qcom-qmp: Correct
READY_STATUS poll break condition") I failed to conclude that the
PHYSTATUS bit of the PCS_STATUS register used in PCIe and USB3 falls as
the PHY gets ready. Similar to the prior bug with UFS the code will
generally get past the check before the transition and thereby
"succeed".

Correct the name of the register used PCIe and USB3 PHYs, replace
mask_pcs_ready with a constant expression depending on the type of the
PHY and check for the appropriate ready state.
