[PATCH v3 0/4] clk: imx8mp: fix parents of AUDIOMIX DSP/OCRAM_A

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

Correct the parent of the AUDIOMIX DSP and OCRAM_A clock gates by setting
it to AUDIO_AXI_CLK_ROOT, instead of AUDIO_AHB_CLK_ROOT. Additionally, set
the frequency of AUDIO_AXI_CLK_ROOT to 800MHz instead of the current
400MHz.

[PATCH v3 1/4] dt-bindings: clock: imx8mp: add axi clock

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

Some components of AUDIOMIX (i.e: DSP, OCRAM_A) are clocked by
AUDIO_AXI_CLK_ROOT. Since the AUDIOMIX block control manages the clock
gates for those components, include their root clock in the list of clocks
consumed by the IP.

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

The DSP and OCRAM_A modules from AUDIOMIX are clocked by
AUDIO_AXI_CLK_ROOT, not AUDIO_AHB_CLK_ROOT. Update the clock data
accordingly.

[PATCH v3 4/4] arm64: dts: imx8mp: change AUDIO_AXI_CLK_ROOT freq. to 800MHz

[Laurentiu Mihalcea]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

AUDIO_AXI_CLK_ROOT can't run at currently requested 600MHz w/ its parent
SYS_PLL1 configured at 800MHz. Configure it to run at 800MHz as some
applications running on the DSP expect the core to run at this frequency
anyways. This change also affects the AUDIOMIX NoC.

would it be possible to also have patch no. 3 merged via the IMX CLK tree? I'd like to at least keep the first 3 patches together as they all fix the issue of OCRAM_A/DSP clocks having the wrong parent. if not, Shawn would you mind picking up patches 3 and 4? Thanks!
