hisilicon-ev200 / goke-gk7205v200: IMX335 companion to openhisilicon #99

[widgetii]

Summary

Bumps hisilicon-opensdk to 8b5e47f (openipc/openhisilicon PR #99 merged) and applies four firmware-side companion changes that PR #99 referenced but were never landed.

1. Bump HISILICON_OPENSDK_VERSION b2db4db → 8b5e47f. Pulls in the merged openhisilicon PR #99 (fuse sony_imx335 + sony_imx335_fpv into one driver) along with the M7 flex-crop dispatch.

2. Drop sony_imx335_fpv from the install manifest. PR #99 deleted the source directory; without removing this line the SDK build fails on missing target. (hisilicon-opensdk.mk)

3. Fix gk7205v200 IMX335 sensor INCK = 27 MHz → 37.125 MHz. The vendor gk7205v200_vi.ko blob programs PERI_CRG60 to feed the sensor a 27 MHz reference clock at module_init; the Hisilicon counterpart leaves it at the SoC default 37.125 MHz. Without this INI override, gk's pixel rate is ~73% of ev's across every IMX335 mode. Applied to all 4 gk7205v200 IMX335 INIs (linear + WDR × 4M + 5M).

4. Add high-fps/ preset directory with M7 flex-crop example INIs for the V4 boards (ev200 + gk7205v200), naming pattern <sensor>_<width>x<height>_<fps>fps.ini:

   File	Sensor	Resolution	Wire fps
   imx335_800x480_240fps.ini	IMX335	800×480	~185
   imx335_1280x720_120fps.ini	IMX335	1280×720	~115
   imx307_1280x720_60fps.ini	IMX307 (renamed)	1280×720	60

   Both IMX335 presets use Isp_SnsMode=4 (M7 flex-crop, added by PR #99). The 1280×720 entry gives an apples-to-apples view next to the existing IMX307 720p preset.

   Also consolidates gk7205v200's 60fps/ (single IMX307 file) into high-fps/ — same purpose, single directory. The two commented-out cli references in rubyfpv/files/tweaksys and legacy/datalink/files/tweaksys updated to the new path.

INIs are minimal (≈30 lines); full per-crop fps table + tuning guide lives in openhisilicon/docs/imx335-v4-high-fps.md (linked from each INI header) to keep flash footprint small.

Verified

UDP-RTP push from camera → measurement host, h.265 at 4 Mbps target, fresh-booted boards:

• hi3516ev300 + IMX335 at 800×480 @240 → 185.1 fps wire (3-min soak, stable)
• gk7205v300 + IMX335 at 800×480 @240 → 185.1 fps wire (3-min soak, stable)
• hi3516ev300 + IMX335 at 1280×720 @100 → 98.2 fps wire
• gk7205v300 + IMX335 at 1280×720 @100 → 98.2 fps wire

Both boards run identically once clock=37.125MHz is applied to gk — same silicon per the openhisilicon PR #99/100 CRG decode (see kaeru imx335-ev-vs-gk-crg-decode-2026-05-12).

Test plan

• Cross-compile clean: make BOARD=hi3516ev200_lite all
• Cross-compile clean: make BOARD=gk7205v200_lite all
• Stock M0-M6 IMX335 modes unaffected by clock= change (verified on gk)
• M7 flex-crop dispatch works at the two new preset crops
• CI green
