82efed175b dt-bindings: clock: qcom: Add camera clock controller for SM8750 SoC 
Add device tree bindings for the camera clock controller on
Qualcomm SM8750 platform. The camera clock controller is split between
camcc and cambist. The cambist controls the mclks of the camera clock
controller.

d6205a1878 clk: qcom: rcg2: compute 2d using duty fraction directly 
The duty-cycle calculation in clk_rcg2_set_duty_cycle() currently
derives an intermediate percentage `duty_per = (num * 100) / den` and
then computes:

    d = DIV_ROUND_CLOSEST(n * duty_per * 2, 100);

This introduces integer truncation at the percentage step (division by
`den`) and a redundant scaling by 100, which can reduce precision for
large `den` and skew the final rounding.

Compute `2d` directly from the duty fraction to preserve precision and
avoid the unnecessary scaling:

    d = DIV_ROUND_CLOSEST(n * duty->num * 2, duty->den);

This keeps the intended formula `d ≈ n * 2 * (num/den)` while performing
a single, final rounded division, improving accuracy especially for small
duty cycles or large denominators. It also removes the unused `duty_per`
variable, simplifying the code.

There is no functional changes beyond improved numerical accuracy.

3dadc1dc5e clk: qcom: rpmh: Update the clock suffix for Glymur 
The current RPMh VRM clock definitions do not accurately represent the
hardware mapping of these clocks. While there is no functional impact,
this update aligns the definitions with the hardware convention by adding
the appropriate suffix to indicate the clock divider and the E0 variant
for the C3A_E0, C4A_E0, C5A_E0, and C8A_E0 resources on Glymur.

new generated header file for the offsets into the mshv_vtl_cpu_context
structure to be used by the low-level assembly code.  But it didn't add
the .gitignore file to go with it, so 'git status' and friends will

Let's add the gitignore file before somebody thinks that generated
