This is v5 patch-set (Basically same as v4, but rebased to next-20240628). We already have for_each_endpoint_of_node(), but some drivers are not using it. This patch-set replace it. [o] done [*] this patch-set [o] tidyup of_graph_get_endpoint_count() (A) [o] replace endpoint func - use endpoint_by_regs() [*] replace endpoint func - use for_each() [ ] add new port function [ ] add new endpoint function I noticed that my posted 1 patch on (A) was not yet included on linus/master (= [1/7]). I have included it. Dan is indicating it needs _scoped() macro, but it is new new feature. So I think we want to have separate this patch-set and _scoped() patch-set. I asked it to ML/Maintainer but no responce, so v4 doesn't include it. It will be handled by other patch-set in the future. v4 -> v5 - rebase on linux-next 2024-06-28 v3 -> v4 - fixup ret handling v2 -> v3 - don't initialize pointer. - add Reviewed-by / Acked-by - include not-yet applied missing patch v1 -> v2 - fixup TI patch Link: https://lore.kernel.org/r/8734sf6mgn.wl-kuninori.morimoto.gx@renesas.com Link: https://lore.kernel.org/r/87cyrauf0x.wl-kuninori.morimoto.gx@renesas.com Link: https://lore.kernel.org/r/87le3soy08.wl-kuninori.morimoto.gx@renesas.com Link: https://lore.kernel.org/r/87v82q4yg0.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (7): gpu: drm: replace of_graph_get_next_endpoint() gpu: drm: use for_each_endpoint_of_node() hwtracing: use for_each_endpoint_of_node() media: platform: microchip: use for_each_endpoint_of_node() media: platform: ti: use for_each_endpoint_of_node() media: platform: xilinx: use for_each_endpoint_of_node() staging: media: atmel: use for_each_endpoint_of_node() drivers/gpu/drm/drm_of.c | 4 +++- drivers/gpu/drm/omapdrm/dss/base.c | 3 +-- .../drm/panel/panel-raspberrypi-touchscreen.c | 2 +- drivers/gpu/drm/tiny/arcpgu.c | 2 +- .../hwtracing/coresight/coresight-platform.c | 4 ++-- .../microchip/microchip-sama5d2-isc.c | 21 +++++++------------ .../microchip/microchip-sama7g5-isc.c | 21 +++++++------------ .../media/platform/ti/am437x/am437x-vpfe.c | 12 +++++------ .../media/platform/ti/davinci/vpif_capture.c | 14 ++++++------- drivers/media/platform/xilinx/xilinx-vipp.c | 9 ++------ .../deprecated/atmel/atmel-sama5d2-isc.c | 10 +++------ .../deprecated/atmel/atmel-sama7g5-isc.c | 10 +++------ 12 files changed, 44 insertions(+), 68 deletions(-)
