Comprehensive compat fixes enabling the CV500 opensdk modules to build against modern Linux kernels (tested with 7.0-rc6 via hi3516av300_neo). OSAL (osal/hi3516cv500/): - access_ok 3→2 args (5.0+) - set_fs/get_fs/get_ds removal (5.10+) - platform_driver.remove void return (6.11+) - vm_flags read-only (6.3+) - get_random_int → get_random_u32 (6.1+) - PDE_DATA → pde_data (5.17+) - file_operations → proc_ops for /proc (5.6+) - strlcpy → strscpy (6.8+) - DEFINE_SEMAPHORE 2-arg (6.4+) - timer_setup / from_timer (4.15+) - do_gettimeofday removal (5.0+) - rtc_time_to_tm / rtc_tm_to_time removal (5.6+) - mmap_sem → mmap_lock (5.8+) - ATTRIBUTE_GROUPS + const bus_type callbacks (7.0) - list_for_each → osal_list_for_each for type safety (7.0) - dma_alloc_from_contiguous 4th arg (4.15+) MMZ (osal/hi3516cv500/mmz/): - Drop hisi_allocator (vendor CMA, not in mainline); CMA-only on 5.16+ - __dma_clear_buffer → memset + cache flush (6.x+) - __pte_offset_map → get_user_pages_fast (6.5+) - hisi_get_cma_zone → dev_get_cma_area default CMA (5.16+) Init wrappers (init/hi3516cv500/): - platform_driver.remove void return in all 31 files - MODULE_LICENSE "Proprietary" → "GPL" (printk GPL-only export 6.x+) - MODULE_LICENSE added to jpegd_init - ctl_table.child + register_sysctl_table removal (6.6+) Drivers: - sensor_i2c: hi_i2c_master_send → i2c_master_send, i2c_new_client_device - sensor_spi: spi_busnum_to_controller, const spi_bus_type (7.0) - pwm/piris: timer_setup, PTR_ERR case fix, platform_remove - cipher: proc_ops, of_dma_configure 3-arg (4.18+), platform_remove - ISP init: platform_remove - hi_user: disabled (sched_setscheduler not exported on 6.x+) Build system: - Kbuild: -isystem for GCC built-in includes (stdarg.h under -nostdinc) - obj/hi3516cv500: stub .cmd files for prebuilt blobs (modpost 7.0) - printk shim in OSAL for 4.9-era blobs referencing old symbol name CI: - Add hi3516av300_neo (CV500 7.0 kernel) build target Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

Add a "neo" variant for the hi3516av300 board running OpenIPC on the upstream-patches kernel branch (Linux 7.0+) instead of the vendor 4.9.37 kernel. Per OpenIPC/openhisilicon#51, the CV500 platform has zero direct kernel API calls in blobs — everything goes through OSAL, making it a top-priority candidate for kernel modernization. New files: - br-ext-chip-hisilicon/configs/hi3516av300_neo_defconfig Buildroot defconfig with glibc toolchain, 16MB flash, upstream-patches kernel, BR2_OPENIPC_VARIANT="neo". - br-ext-chip-hisilicon/board/hi3516cv500/hi3516av300.neo.config Seed kernel config with ARCH_HI3516DV300, COMMON_CLK_HI3516DV300, earlycon at 0x120a0000, ZRELADDR=0x80008000, CMA, MTD/SPI-NOR. Aggressive size trimming (no IPv6, no NETFILTER, no input/sound/USB, no JFFS2/CRAMFS/loop/RAM block) keeps uImage under 2048KB limit. - br-ext-chip-hisilicon/board/hi3516cv500/neo-post-image.sh Concatenates zImage + DTB and wraps as uImage (load 0x80008000).

Summary
Comprehensive compat fixes enabling CV500 opensdk modules to build against Linux 5.0 through 7.0 kernels. Tested with
hi3516av300_neofirmware variant on Linux 7.0-rc6 (upstream-patches kernel).Per #51, CV500 has zero direct kernel API calls in blobs — everything goes through OSAL. This PR ports the OSAL and all source-compiled modules to the modern kernel API.
