[PATCH v4 0/5] Add modem Clock controller (MSS CC) driver for SC7180

[PATCH v4 0/5] Add modem Clock controller (MSS CC) driver for SC7180

[Taniya Das]

[v4]
 * Split the GCC MSS clocks and Modem clock driver.
 * Update mss_regmap_config to const.
 * Rename the Documentation binding as per the latest convention.
 * Minor comments of clock-names/clocks properties updated.

[v3]
  * Add clocks/clock-names required for the MSS clock controller.
  * Add pm_ops to enable/disable the required dependent clock.
  * Add parent_data for the MSS clocks.
  * Update the GCC MSS clocks from _CBCR to _CLK.

[v2]
  * Update the license for the documentation and fix minor comments in the
    YAML bindings.

[v1]
  * Add driver support for Modem clock controller for SC7180 and also
    update device tree bindings for the various clocks supported in the
    clock controller.

I did see the same issue and then when I re-ordered by patches
dt-bindings: clock: Add support for Modem clocks in GCC (dependent) on 
this binding patch, I no longer encountered the issue.
https://patchwork.kernel.org/patch/11389243/

Re: [PATCH v4 3/5] dt-bindings: clock: Add YAML schemas for the QCOM MSS clock bindings

[Sibi Sankar]

Hey Taniya,

+    <&gcc GCC_MSS_NAV_AXIS_CLK>,

error is because of ^^ typo
it should be GCC_MSS_NAV_AXI_CLK
instead, with that dt_bindings
check will go though.
