The GPT timers used for avb media clock recovery (and avb hw timer) have as constraint on rate only when
using the external clock as counter clock (then the frequency should be < 1/4 peripheral clock).
For SoCs that can root the peripheral clock directly from the audio pll, use the pll frequency as-is
for better precision for media clock recovery sampling.The TPM timer used for i.MX93 have no constraint on bus clock domain and counter clock domain, so use the
audio pll as counter clock without any division also.Signed-off-by: Marouen Ghodhbane

- Multiply the numerator and denomerator of the fractional part of the audio pll to have
better granularity of audio pll adjustement when changing the numerator part on the fly.
- Keep mfd < 2**21 to avoid u32 value overflow on multiplication in recalc_rate() function while using do_div()Signed-off-by: Marouen Ghodhbane

Currently, the coherent DMA memory is always mapped as writecombine
and uncached, ignored the 'dma-coherent' property in device node,
this patch is to map the memory as writeback and cached when the
device has 'dma-coherent' property.Signed-off-by: Hou Zhiqiang

As SGI is used as IPI in Linux, so let's replace SGI with some SPI irqs
which is not used by as hardware, SPI irq can also be triggered by
writing to SGI interrupt by CPU Core.Signed-off-by: Hou Zhiqiang

Add ICC_CMD_DUMP_TIME option mode for ipi_baremetal_handle
to support dump time interrupt from baremetal core.For this function add two option modes, one is
ICC_CMD_TX_DATA which used for data transfer, the other is
ICC_CMD_DUMP_TIME which used for print interrupt handle
information in receiver core.Signed-off-by: Chunguang Li
