The si544 driver had a rounding problem that using the result of clk_round_rate
may set the clock to yet another rate, for example:
clk_round_rate(195000000) = 194999999
clk_round_rate(194999999) = 194999998
Clients would expect that after clk_set_rate(clk, freq2=clk_round_rate(clk, freq)) the
chip will be running at exactly freq2.
The problem was in the calculation of the feedback divider, it was always rounded
down instead of to the nearest possible VCO value.
After this change, the following holds true for any supported frequency:
actual_freq = clk_round_rate(clk, freq);
clk_set_rate(clk, actual_freq);
clk_round_rate(clk, actual_freq) == actual_freq && clk_get_rate(clk) == actual_freq

We only have two users of the debug_init hook, and we recently stopped

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
The return value of these functions were never checked in the end
anyway, so it is obvious this does not change any functionality :)

This cleans up the init code a lot, and there's no need to return an

The current defconfig is inconsistent as it selects the mailbox and
the clock for the hi6220 and the hi3660 without having their Kconfigs
making sure the dependencies are correct. It ends up when selecting
different versions for the kernel (for example when git bisecting)
those options disappear and they don't get back, leading to unexpected
behaviors. In our case, the cpufreq driver does no longer work because
the clock fails to initialize due to the clock stub and the mailbox
missing.
In order to have the dependencies correctly set when defaulting, let's
do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk
automatically") where we select automatically the driver when the
parent driver is selected. With sensible defaults in place, we can leave
other choices for EXPERT.

The USB and PCIE pipe clocks are sourced from external clocks
inside the QMP USB/PCIE PHYs. Enabling or disabling of PIPE RCG
clocks is dependent on PHY initialization sequence hence
update halt_check to BRANCH_HALT_SKIP for these clocks so
that clock status bit is not polled when enabling or disabling
the clocks. It allows to simplify PHY client driver code which
is both user and source of the pipe_clk and avoid error logging
related status check on clk_disable/enable.

Some GDSCs might have software control to turn them off, but we might
want to keep them enabled always, in some cases because of lack of

Initially we tried modeling clocks via the devicetree before switching
to clocks declared in the clock drivers and only exporting specific
ids to the devicetree.
As the old code was in the kernel for 1-2 releases when the new mode
of operation was added we kept it for backwards compatibility.
That deprecation notice is in the binding since july 2014, so nearly
4 years now and I think it's time to drop the old cruft.
Especially as at the time using the mainline kernel on Rockchip devices
was not really possible, except for experiments on the really old socs of
the rk3066 + rk3188 line, so there shouldn't be any devicetrees still
around that rely on that code.

Until commit 05f814402d6174 ("clk: meson: add fdiv clock gates") we
relied on the bootloader to enable the fclk_div clock gates. It turns
out that our clock tree is incomplete at least on Meson8b (tested with
an Odroid-C1, which uses an RGMII PHY) because after the mentioned
commit Ethernet is not working anymore (no RX/TX activity can be seen).
At the same time Ethernet was still working on Meson8m2 with a RMII PHY.
Testing has shown that as soon as "fclk_div2" is disabled Ethernet stops
working on Odroid-C1. Unfortunately it's currently not clear what the
Ethernet controller IP block uses the fclk_div2 clock for. Mark the
clock as CLK_IS_CRITICAL to keep it enabled (as it's already enabled by
most bootloaders by default, which is why we didn't notice it before).
