Add edma2 for i.mx7ulp by version v3, since v2 has already been used by mcf-edma. The big changes based on v1 are belows: 1. only one dmamux. 2. another clock dma_clk except dmamux clk. 3. 16 independent interrupts instead of only one interrupt for all channels.

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

The Tegra210 ADMA supports two modes for transferring data to a FIFO which are ... 1. Transfer data to/from the FIFO as soon as a single burst can be transferred. 2. Transfer data to/from the FIFO based upon FIFO thresholds, where the FIFO threshold is specified in terms on multiple bursts. Currently, the ADMA driver programs the FIFO threshold values in the FIFO_CTRL register, but never enables the transfer mode that uses these threshold values. Given that these have never been used so far, simplify the ADMA driver by removing the programming of these threshold values.

When a DMA client driver does not set the DMA_PREP_INTERRUPT because it does not want to use interrupts for DMA completion or because it can not rely on DMA interrupts due to executing the memcpy when interrupts are disabled it will poll the status of the transfer. Since we can not tell from any EDMA register that the transfer is completed, we can only know that the paRAM set has been sent to TPTC for processing we need to check the residue of the transfer, if it is 0 then the transfer is completed.

For memcpy we never stored the start address of the transfer for the pset which rendered the memcpy residue calculation completely broken. In the edma_residue() function we also need to to some correction for the calculations: Instead waiting for all EDMA channels to be idle (in a busy system it can take few iteration to hit a point when all queues are idle) wait for the event pending on the given channel (SH_ER for hw synchronized channels, SH_ESR for manually triggered channels). If the position returned by EMDA is 0 it implies that the last paRAM set has been consumed and we are at the closing dummy set, thus we can conclude that the transfer is completed and we can return 0 as residue.

The tx_status is most likely going to be asked for the current transfer, so check that first then try to fall back to lookup of non started transfers.

The current driver works perfectly fine on every generation of the JZ47xx SoCs, except on the JZ4740. There, when hardware descriptors are chained together (with the LINK bit set), the next descriptor isn't automatically fetched as it should - instead, an interrupt is raised, even if the TIE bit (Transfer Interrupt Enable) bit is cleared. When it happens, the DMA transfer seems to be stopped (it doesn't chain), and it's uncertain how many bytes have actually been transferred. Until somebody smarter than me can figure out how to make chained descriptors work on the JZ4740, we now disable chained descriptors on that particular SoC.

Tegra's APB DMA engine updates words counter after each transferred burst of data, hence it can report transfer's residual with more fidelity which may be required in cases like audio playback. In particular this fixes audio stuttering during playback in a chromium web browser. The patch is based on the original work that was made by Ben Dooks and a patch from downstream kernel. It was tested on Tegra20 and Tegra30 devices.

Matching on the 'cpus' node was a bad choice because the schema is incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus schema which checks the general structure, it is also redundant to do so in the Risc-V CPU schema. The downside is one could conceivably mix different architecture's cpu nodes or have typos in the compatible string. The latter problem pretty much exists for every schema.
