Since the loopbacktest clock is not exported and is not touched in the
driver, it has to be added to rk3188_critical_clocks to be protected from
being disabled and in order to get the emac working.

This reverts commit 82f4b67f018c88a7cc9337f0067ed3d6ec352648.
According to a subsequent revert in the vendor kernel, the original
change was based on unclear documentation and was in fact incorrect.
Emprically, my board's HS200 eMMC at 200MHZ apparently gets lucky with a
phase where this had no impact, but limiting max-frequency to 150MHz to
match the nominal capability of the I/O pins made it virtually unusable,
constantly throwing errors and retuning. With this revert, it starts
behaving perfectly at 150MHz too.

Commit 1627f683636d ("clk: rockchip: Handle clock tree for rk3288w variant")
added the check for rk3288w-specific clock-tree changes but in turn would
require a double-compatible due to re-using the main rockchip,rk3288-cru
compatible as entry point.
The binding change actually describes the compatibles as one or the other
so adapt the code accordingly and add a real second entry-point for the
clock controller.

The revision rk3288w has a different clock tree about "hclk_vio"
clock, according to the BSP kernel code.
This patch handles this difference by detecting which device-tree
we are using. If it is a "rockchip,rk3288-cru", let's register
the clock tree as it was before. If the device-tree node is
"rockchip,rk3288w-cru", we will apply the difference with this
version of this SoC.
Noticed that this new device-tree compatible must be handled in
bootloader such as u-boot.

The rk3036 pll type exposes its lock status in both its pllcon registers
as well as the General Register Files. To remove one dependency convert
it to the "internal" lock status, similar to how rk3399 handles it.

Instead of open coding the polling of the lock status, use the
handy regmap_read_poll_timeout for this. As the pll locking is
normally blazingly fast and we don't want to incur additional
delays, we're not doing any sleeps similar to for example the imx
clk-pllv4 and define a very safe but still short timeout of 1ms.

Contrary to previous SoCs, bcm2711 doesn't have a prescaler in the PLL
feedback loop. Bypass it by zeroing fb_prediv_mask when running on
bcm2711.
Note that, since the prediv configuration bits were re-purposed, this
was triggering miscalculations on all clocks hanging from the VPU clock,
notably the aux UART, making its output unintelligible.

Reusing the generic struct vc5_hw_data for all blocks is handy. However it
implies we allocate space the div_int and div_frc fields even for the
output drivers where they are unused, and the clk_output_cfg0 and
clk_output_cfg0_mask fields for all components even though they are used
only for the output drivers.
Use a dedicated struct for the output drivers so that each block uses
exactly the fields it needs, not more.

When getting the names of the child nodes, kasprintf is used to
allocate memory which is used to create the string for the node
name. Unfortunately, there is no memory check to determine
if this allocation fails, it may cause an error when trying
to get child node name.
This patch will check if the memory allocation fails, and returns
and -ENOMEM error instead of blindly moving on.

There are a several places where printing an error message of
init.name occurs after init.name has been kfree'd. Also the failure
message is duplicated each time in the code. Fix this by adding
a registration error failure path for these cases, moving the
duplicated error messages to one common point and kfree'ing init.name
only after it has been used.
Changes also shrink the object code size by 171 bytes (x86-64, gcc 9.3):

Fixed ops were already identical, this adds support for non-fixed ops by
sharing between trion and lucid.
This also changes the names for trion ops to be consistent with the rest.
Note LUCID_PCAL_DONE is renamed to TRION_PCAL_DONE because it is wrong for
lucid, LUCID_PCAL_DONE should be BIT(27). Next patch will address this.

Pull clk updates from Stephen Boyd:
"It looks like a smaller batch of clk updates this time around.
In the core framework we just have some minor tweaks and a debugfs
feature, so not much to see there. The driver updates are fairly well
split between AT91 and Qualcomm clk support. Adding those two drivers
together equals about 50% of the diffstat.
Otherwise, the big amount of work this time was on supporting
Broadcom's Raspberry Pi firmware clks.
Highlights:
Core:
- Document clk_hw_round_rate() so it gets some more use
- Remove unused __clk_get_flags()
- Add a prepare/enable debugfs feature similar to rate setting
New Drivers:
- Add support for SAMA7G5 SoC clks
- Enable CPU clks on Qualcomm IPQ6018 SoCs
- Enable CPU clks on Qualcomm MSM8996 SoCs
- GPU clk support for Qualcomm SM8150 and SM8250 SoCs
- Audio clks on Qualcomm SC7180 SoCs
- Microchip Sparx5 DPLL clk
- Add support for the new Renesas RZ/G2H (R8A774E1) SoC
Updates:
- Make defines for bcm63xx-gate clks to use in DT
- Support BCM2711 SoC firmware clks
- Add HDMI clks for BCM2711 SoCs
- Add RTC related clks on Ingenic SoCs
- Support USB PHY clks on Ingenic SoCs
- Support gate clks on BCM6318 SoCs
- RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs
- Use poll_timeout functions in Rockchip clk driver
- Support Rockchip rk3288w SoC variant
- Mark mac_lbtest critical on Rockchip rk3188
- Add CAAM clock support for i.MX vf610 driver
- Add MU root clock support for i.MX imx8mp driver
- Amlogic g12: add neural network accelerator clock sources
- Amlogic meson8: remove critical flag for main PLL divider
- Amlogic meson8: add video decoder clock gates
- Convert one more Renesas DT binding to json-schema
- Enhance critical clock handling on Renesas platforms to only
consider clocks that were enabled at boot time"

HHI_VIID_CLK_CNTL[19] is not part of the public S805 datasheet. However,
the GXBB driver defines this bit as a gate called "vclk2" and in the
3.10 kernel GPL code dump the following line can found:
WRITE_LCD_CBUS_REG_BITS(HHI_VIID_CLK_CNTL, 0, 19, 1); //disable vclk2_en
Add this gate clock to the Meson8/Meson8b/Meson8m2 clock controller to
complete the VCLK2 clock tree.

HHI_VID_CLK_CNTL[19] is documented as CLK_EN0. This description is the
same in the public S912 datasheet and the GXBB driver calls this gate
"vclk". Add this gate clock to the Meson8/Meson8b/Meson8m2 clock
controller because it's needed to make the video output work.

Drop CLK_IS_CRITICAL from fclk_div2. This was added because we didn't
know the relation between this clock and RGMII Ethernet. It turns out
that fclk_div2 is used as "timing adjustment clock" to generate the RX
delay on the MAC side - which was enabled by u-boot on Odriod-C1. When
using the RX delay on the PHY side or not using a RX delay at all then
this clock can be disabled.

The display gpll0 branch clock inside GCC needs to always be enabled.
Otherwise the AHB clk (disp_cc_mdss_ahb_clk_src) for the display clk
controller (dispcc) will stop clocking while sourcing from gpll0 when
this branch inside GCC is turned off during unused clk disabling. We can
never turn this branch off because the AHB clk for the display subsystem
is needed to read/write any registers inside the display subsystem
including clk related ones. This makes this branch a really easy way to
turn off AHB access to the display subsystem and cause all sorts of
mayhem. Let's just make the clk ops keep the clk enabled forever and
ignore any attempts to disable this clk so that dispcc accesses keep
working.
