Commit 9b47105f54 ("clk: qcom: dispcc-qcs615: Add QCS615 display clock
controller driver") adds the config QCS_DISPCC_615, which selects the
non-existing config QCM_GCC_615. Probably, this is just a three-letter
abbreviation mix-up here, though. There is a config named QCS_GCC_615,
and the related config QCS_CAMCC_615 selects that config.

Fix the typo and use the intended config name in the select command.

Rework nss_port5 to use the new multiple configuration implementation
and correctly fix the clocks for this port under some corner case.

In OpenWrt, this patch avoids intermittent dmesg errors of the form
nss_port5_rx_clk_src: rcg didn't update its configuration.

This is a mechanical, straightforward port of
commit e88f03230d
("clk: qcom: gcc-ipq8074: rework nss_port5/6 clock to multiple conf")
to gcc-ipq6018, with two conflicts resolved: different frequency of the
P_XO clock source, and only 5 Ethernet ports.

2d945dde7f Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux 
Pull clk updates from Stephen Boyd:
 "This is the usual collection of primarily clk driver updates.

  The big part of the diff is all the new Qualcomm clk drivers added for
  a few SoCs they're working on. The other two vendors with significant
  work this cycle are Renesas and Amlogic. Renesas adds a bunch of clks
  to existing drivers and supports some new SoCs while Amlogic is
  starting a significant refactoring to simplify their code.

  The core framework gained a pair of helpers to get the 'struct device'
  or 'struct device_node' associated with a 'struct clk_hw'. Some
  associated KUnit tests were added for these simple helpers as well.

  Beyond that core change there are lots of little fixes throughout the
  clk drivers for the stuff we see every day, wrong clk driver data that
  affects tree topology or supported frequencies, etc. They're not found
  until the clks are actually used by some consumer device driver.

  New Drivers:
   - Global, display, gpu, video, camera, tcsr, and rpmh clock
     controller for the Qualcomm Milos SoC
   - Camera, display, GPU, and video clock controllers for Qualcomm
     QCS615
   - Video clock controller driver for Qualcomm SM6350
   - Camera clock controller driver for Qualcomm SC8180X
   - I3C clocks and resets on Renesas RZ/G3E
   - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
     Renesas RZ/V2H(P) and RZ/V2N
   - SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
   - SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
   - Ethernet clocks and resets on Renesas RZ/G3E
   - Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
     (R9A09G087) SoCs
   - Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
   - Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
     RZ/V2N

  Updates:
   - Support atomic PWMs in the PWM clk driver
   - clk_hw_get_dev() and clk_hw_get_of_node() helpers
   - Replace round_rate() with determine_rate() in various clk drivers
   - Convert clk DT bindings to DT schema format for DT validation
   - Various clk driver cleanups and refactorings from static analysis
     tools and possibly real humans
   - A lot of little fixes here and there to things like clk tree
     topology, missing frequencies, flagging clks as critical, etc"

b7b0799f0d clk: qcom: videocc-sm8550: Allow building without SM8550/SM8560 GCC 
>From the build perspective, the videocc-sm8550 driver doesn't depend on
having one of the GCC drivers enabled. It builds just fine without the GCC
driver. In practice, it doesn't make much sense to have it enabled without
the GCC driver, but currently this extra dependency is inconsistent with
most of the other VIDEOCC entries in Kconfig. This can easily cause
confusion when you see the VIDEOCC options for some of the SoCs but not for
all of them.

Let's just drop the depends line to allow building the videocc driver
independent of the GCC selection. Compile testing with randconfig will also
benefit from keeping the dependencies minimal.
