libraries: hi3519dv500 (V5 aarch64) sensor drivers from source#203
Merged
Conversation
Add the Hi3519DV500/Hi3516DV500 (V5/SS626, aarch64 Cortex-A55) sensor
drivers, compiled from the vendor SDK source the same way the cv500/cv300/
hi3519v101 chips are (per-sensor <sns>_cmos.c + <sns>_sensor_ctl.c built
against the DV500 ISP/MPI headers). cv6xx's cis_/sensor_common refactor does
not apply here: the DV500 ISP API differs from cv6xx's, and the vendor source
matches the DV500 headers directly.
8 sensors -> libsns_*.{so,a}: sc450ai, os04a10, os04a10_slave, os08a20,
sc850sl, imx347_slave, imx515, gst412c.
Also adds the DV500 vendor ISP/MPI headers (libraries/isp/include/hi3519dv500,
kernel/include/hi3519dv500 trimmed to the set the sensors include) and the
libraries/Makefile CHIPARCH filter.
Verified: all 8 build to aarch64 ELF via
`make -C libraries CHIPARCH=hi3519dv500` with aarch64-openipc-linux-musl.
Kernel modules (open_*.ko) are a separate follow-up.

Adds the Hi3519DV500 / Hi3516DV500 (V5/SS626, aarch64 Cortex-A55) sensor drivers, compiled from the vendor SDK source — the first piece of DV500 SoC support.
Approach
DV500 follows the vendor-framework convention already used by cv500/cv300/hi3519v101 (per-sensor
<sns>_cmos.c+<sns>_sensor_ctl.cbuilt against the chip's ISP/MPI headers), not cv6xx'scis_/sensor_commonrefactor — the DV500 ISP API differs from cv6xx's, so the vendor source matches the DV500 headers directly.What's included
libraries/sensor/hi3519dv500/— 8 sensors →libsns_*.{so,a}:sc450ai,os04a10,os04a10_slave,os08a20,sc850sl,imx347_slave,imx515,gst412c(the names the OpenIPC firmware osdrv expects).libraries/isp/include/hi3519dv500/+kernel/include/hi3519dv500/— DV500 vendor ISP/MPI headers (trimmed to the set the sensors include).libraries/Makefile—CHIPARCH=hi3519dv500sensor filter.Verification
All 8 build to aarch64 ELF via the canonical
make -C libraries CHIPARCH=hi3519dv500(the way buildroot invokes it), using theaarch64-openipc-linux-musltoolchain. No build artifacts committed (.so/.o/.aare gitignored;hisilicon-opensdkbuilds them).Follow-up
Kernel modules (
open_*.ko— OSAL/MMZ/sys_config/mipi/peripherals +.o-blob-wrapped core, plus ahi3519dv500.kbuild) are a separate, larger phase.
