OF-graph base DT binding is used on V4L2, and ALSA SoC is using different style of DT today. Now ALSA SoC supports simple-card driver for generic/simple sound card, and we have simple-scu-card driver for simple-card + ALSA DPCM case. In the future, V4L2 / ALSA will support HDMI, and then, DT bindings between V4L2 / ALSA should be merged. This patch adds new Audio Graph SCU Card which is OF-graph base of simple-scu-card Signed-off-by:

Current asoc_simple_card_parse_daifmt is keeping backward compatibility for bitmaster/framemaster which didn't use phandle. The keep compatibility, it is checking prefix length, but it is too strict. let's loosen it. Otherwise, OF-graph base sound card which doesn't have prefix can't detect daifmt. Signed-off-by:

ALSA SoC needs to know connected DAI ID for detecting. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new snd_soc_get_dai_id() and its related .of_xlate_dai_id callback on component driver. In below case, we can handle Sound port (= port@2) as ID = 0 if .of_xlate_dai_id has its support. hdmi { port@0 { /* VIDEO */ }; port@1 { /* VIDEO */ }; port@2 { /* SOUND */ }; }; Signed-off-by: -

Renesas R-Car Gen3 can output HDMI sound if SSIU/SSI are connected to R-Car built-in HDMI device (R-Car Gen3 built-in HDMI device will be controlled by DRM/KMS driver). If SSIx was connected to HDMI0/1 on DT, SSI driver will detect it automatically by this patch. Note is that now Renesas R-Car sound driver is assuming that it is using OF-graph base simple card for HDMI sound. Signed-off-by:

To enable OF-graph base DT on rsnd driver, and to keep compatible previous normal sound card style, it need to support both "rcar_sound,dai" and "ports" (or "port") on DT. This patch parses both style. Signed-off-by:

simple-scu-card is almost same as simple-card. This is already explained in document. But simple-card and simple-scu-card both has same explanation for same property. This patch forward explantion to simple-card if possible to avoid duplication. This patch also cleanup DT binding example which is not good matching to simple-scu-card. Signed-off-by:

Finally, OOM happens. The problem is that get_scan_count determines nr_to_scan with eligible zones so although priority drops to zero, it couldn't reclaim any pages if the LRU contains mostly ineligible pages. get_scan_count: size = lruvec_lru_size(lruvec, lru, sc->reclaim_idx); size = size >> sc->priority; Assumes sc->priority is 0 and LRU list is as follows. N-N-N-N-H-H-H-H-H-H-H-H-H-H-H-H-H-H-H-H (Ie, small eligible pages are in the head of LRU but others are almost ineligible pages) In that case, size becomes 4 so VM want to scan 4 pages but 4 pages from tail of the LRU are not eligible pages. If get_scan_count counts skipped pages, it doesn't reclaim any pages remained after scanning 4 pages so it ends up OOM happening. This patch makes isolate_lru_pages try to scan pages until it encounters eligible zones's pages. [akpm@linux-foundation.org: clean up mind-bending `for' statement.
