clk: tegra: Don't reset PLL-CX if it is already enabled
Commit
8dce89a1c2cf ("clk: tegra: Don't warn for PLL defaults
unnecessarily") changed the tegra210_pllcx_set_defaults() function
causing the PLL to always be reset regardless of whether it is in-use.
This function was changed so that resetting of the PLL will only be
skipped if the PLL is enabled AND 'pllcx->params->defaults_set' is not
true. However, the 'pllcx->params->defaults_set' is always true and
hence, the PLL is now always reset. This causes the boot to fail on the
Tegra210 Smaug where the PLL is already enabled and in-use. Fix this by
only resetting the PLL if not in-use and only printing the warning that
the defaults are not set after we have checked the default settings.

clk: renesas: r8a7795: Add support for R-Car H3 ES2.0
The Clock Pulse Generator / Module Standby and Software Reset module in
R-Car H3 ES2.0 differs from ES1.x in the following areas:
- More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12),
- Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR,
SYS-DMAC, VIN, VSPB, VSPI,
- Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2,
USB3-IF1, VSPD3, VSPI2,
- Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1.
The goal is twofold:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.
This is achieved by:
- Updating the clock tables for the latest revision (ES2.0), but not
removing clocks that only exist on earlier revisions (ES1.x),
- Detecting the SoC revision at runtime using the new soc_device_match()
API, and fixing up the clocks tables to match the actual SoC
revision, by:
- NULLifying core and module clocks of modules that do not exist,
- Reparenting module clocks that have a different parent on ES1.x.

The same SoC may have different clocks and/or module clock parents,

tables for each SoC revision. However, if the differences are small, it
is much more space-efficient to have a single set of clock tables, and
fix those up at runtime instead.

- Two helpers to NULLify core and module clocks that do not exist on
some revisions (NULLified clocks are skipped during the registration

clk: tegra: Rework pll_u
In normal operation pll_u is under hardware control and has a fixed rate
of 480MHz. Hardware will turn on pll_u on whenever any of the XUSB
powerdomains is on. From a software point of view we model this is if
pll_u is always on using a fixed rate clock. However the bootloader
might or might not have configured pll_u this way. So we will check the
current state of pll_u at boot and reconfigure it if required.
There are 3 possiblities at kernel boot:
1) pll_u is under hardware control: do nothing
2) pll_u is under hardware control and enabled: enable hardware control
3) pll_u is disabled: enable pll_u and enable hardware control
In all cases we also check if UTMIPLL is under hardware control at boot
and configure it for hardware control if that is not the case.
The same is done during SC7 resume.

In case 2 clocks share an enable bit and one of them is enabled by a
driver and the other one is not, CCF will think it's enabled because it
will only look at the HW state. Therefore it will disable the clock and
thus also disable the other clock which was enabled. Solve this by
reading the initial state of the enable bit and incrementing the

clk: sunxi-ng: mp: Adjust parent rate for pre-dividers
The MP style clocks support an mux with pre-dividers. While the driver
correctly accounted for them in the .determine_rate callback, it did
not in the .recalc_rate and .set_rate callbacks.
This means when calculating the factors in the .set_rate callback, they
would be off by a factor of the active pre-divider. Same goes for
reading back the clock rate after it is set.

clk: rockchip: Set "ignore unused" for PMU M0 clocks on rk3399
The PMU Cortex M0 on rk3399 is intended to be used for things like
DDRFreq transitions, suspend/resume, and other things that are the
purview of ARM Trusted Firmware and not the kernel. As such, the
kernel shouldn't be messing with the clocks. Add CLK_IGNORE_UNUSED to
these clocks.
Without this change, the following was observed on a Chromebook with a
rk3399 (using not-yet-upstream ARM Trusted Firmware code and
not-yet-upstream kernel code based on kernel-4.4):
1. We init the clock framework.
2. We start up "DDRFreq", which causes ATF to occasionally fire up the
M0 for transitions. Each time ATF fires up the M0 it will turn on
these clocks and each time it is done it will turn them off.
3. We finally get to the the part of the kernel that calls
clk_disable_unused() and we disables the clocks.
You can see the race above. Basically everything is fine as long as
ARM Trusted Firmware isn't starting up the M0 at exactly the same time
that the kernel is disabling unused clocks. ...but if the race
happens then we go boom.
