Hey folks,

This patchset adds device tree nodes for multiple clock management unit
blocks, MCT, SPI and UART for Exynos8895.

Exynos8895 uses USIv1 for most of its serial buses, except a few that
have been implemented in this series. Support for USIv1 and HSI2C will
be added in the future.

This patchset is dependent on [1] and [2], which add driver support for
CMU and UART.

[2] https://lore.kernel.org/all/20241023090902.538040-1-ivo.ivanov.ivanov1@gmail.com/

Changes in v2:
 - Add r-b from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
 - Change clock-names according to the v2 changes for clk bindings

I cannot merge driver changes into DTS. Are you sure you have driver
dependency?

I cannot merge this either. This is serial tree.

Maybe you these are not really dependencies? What is here depending on
what, specifically? What prevents me from applying it?

Best regards,
Krzysztof

The specified patchsets add driver functionality, as well as bindings,
for serial and clocks. This patchset makes 8895's device tree a user
of them. I guess it's not really a dependency, as 8895 devices should
still function without the driver compatibles merged, but there's gonna
be missing bindings.

Best regards, Ivo.

So the only dependency is on clock bindings? If so, that's the only
message expected here. There are no other dependencies.

Best regards,

Alright, thanks for applying the rest!
