From: Jiada Wang <[email protected]>
Currently each SSI unit's busif dma address is calculated by
following calculation formula:
0xec540000 + 0x1000 * id + busif / 4 * 0xA000 + busif % 4 * 0x400
But according to R-Car3 HW manual 41.1.4 Register Configuration,
ssi9 4/5/6/7 busif data register address
(SSI9_4_BUSIF/SSI9_5_BUSIF/SSI9_6_BUSIF/SSI9_7_BUSIF)
are out of this rule.
This patch updates the calculation formula to correct
ssi9 4/5/6/7 busif data register address.
Fixes: 5e45a6fab3b9 ("ASoc: rsnd: dma: Calculate dma address with consider of BUSIF")

Many thanks for the prompt responses.

Best Regards,

The patch
ASoC: rsnd: dma: fix SSI9 4/5/6/7 busif dma address
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

Subject: [PATCH] ASoC: rsnd: dma: fix SSI9 4/5/6/7 busif dma address
Currently each SSI unit's busif dma address is calculated by
following calculation formula:
0xec540000 + 0x1000 * id + busif / 4 * 0xA000 + busif % 4 * 0x400
But according to R-Car3 HW manual 41.1.4 Register Configuration,
ssi9 4/5/6/7 busif data register address
(SSI9_4_BUSIF/SSI9_5_BUSIF/SSI9_6_BUSIF/SSI9_7_BUSIF)
are out of this rule.
This patch updates the calculation formula to correct
ssi9 4/5/6/7 busif data register address.
