[6.1.y-cip,v2,00/12] Add versa3 clk generator support

Message

This patch series aims to add versa3 clk generator support on
RZ/G2{L,LC,UL}/RZ/Five SMARC EVKs.

All the patches are cherry-picked from the mainline.

Also added missing MTU3 binding patches for RZ/{G2UL,Five} SoCs.

v1->v2:
 * Dropped unneeded patch "clk: Add trace events for rate requests"
 * Added rz_mtu3 binding patches to this series.

Biju Das (10):
  dt-bindings: clock: Add Renesas versa3 clock generator bindings
  dt-bindings: clock: versaclock3: Add description for #clock-cells
    property
  clk: Add support for versa3 clock driver
  clk: vc3: Fix 64 by 64 division
  clk: vc3: Fix output clock mapping
  clk: vc3: Make vc3_clk_mux enum values based on vc3_clk enum
  arm64: dts: renesas: rz-smarc: Use versa3 clk for audio mclk
  dt-bindings: timer: renesas,rz-mtu3: Fix overflow/underflow interrupt
    names
  dt-bindings: timer: renesas,rz-mtu3: Improve documentation
  dt-bindings: timer: renesas,rz-mtu3: Document RZ/{G2UL,Five} SoCs

Stephen Boyd (2):
  clk: Move no reparent case into a separate function
  clk: Introduce clk_hw_determine_rate_no_reparent()

Thanks for the series. I already applied the "rz_mtu3 binding
patches", we already reviewed these in v1, and it passes testing, so
I'm applying the series (with the exception of last 3).

Best regards,

I reviewed this series, and LGTM. I can apply this series.
