* ASoC: SOF: imx8: use resource_sizeJulia Lawall2020-01-011-2/+1
| | | | | | | | | | | | | | | | | | Use resource_size rather than a verbose computation on the end and start fields. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) <smpl> @@ struct resource ptr; @@ - (ptr.end - ptr.start + 1) + resource_size(&ptr) </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> Link: https://lore.kernel.org/r/1577900990-8588-7-git-send-email-Julia.Lawall@inria.fr Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: SOF: imx8: Fix dsp_box offsetDaniel Baluta2019-12-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dsp_box is used to keep DSP initiated messages. The value of dsp_offset is set by the DSP with the first message, so we need a way to bootstrap it in order to get the first message. We do this by setting the correct default dsp_box offset which on i.MX8 is not zero. Very interesting is why it has worked until now. On i.MX8, DSP communicates with ARM core using a shared SDRAM memory area. Actually, there are two shared areas: * SDRAM0 - starting at 0x92400000, size 0x800000 * SDRAM1 - starting at 0x92C00000, size 0x800000 SDRAM0 keeps the data sections, starting with .rodata. By chance fw_ready structure was placed at the beginning of .rodata. dsp_box_base is defined as SDRAM0 + dsp_box_offset and it is placed at the beginning of SDRAM1 (dsp_box_offset should be 0x800000). But because it is zero initialized by default it points to SDRAM0 where by chance the fw_ready was placed in the SOF firmware. Anyhow, SOF commit 7466bee378dd811b ("clk: make freq arrays constant") fw_ready is no longer at the beginning of SDRAM0 and everything shows how lucky we were until now. Fix this by properly setting the default dsp_box offset.

| | | | | | | | | | | | | The memory allocation failure check for priv->pd_dev is incorrectly pointer checking priv instead of priv->pd_dev. Fix this.

* ASoC: SOF: define INFO_ flags in dsp_opsPierre-Louis Bossart2019-10-251-0/+7
| | | | | | | | | | | | | | | Currently the INFO_ flags such as PAUSE/NO_PERIOD_WAKEUP are defined in the SOF PCM core, which doesn't scale. To account for platform variations, these flags need to be set in DSP ops. This patch only moves the definitions and does not change any functionality.
