XiongMai's 85H50AI: hi3516ev300 + imx335 with a motorized zoom/focus
module whose MCU shares /dev/ttyAMA0 with the serial console at 115200,
speaking the XM near-Pelco protocol (majestic-webui's btzoom-xm).
Proven on a lab unit driven end to end through the WebUI
(majestic-webui#227).
The defconfig is a byte-copy of firmware's hi3516ev300_lite_defconfig.
customizer.sh (first boot) sets sensor imx335, the upgrade URL, and the
PTZ trio — ptz_control pelco-xm, ptz_port /dev/ttyAMA0, ptz_caps
'zoom focus' (majestic-webui#261) — and deletes the getty line from
/etc/inittab: the MCU owns the console UART. The edit lands in the
overlay and heals itself (an upgrade that wipes the overlay wipes
/etc/custom.ok too, so the script re-runs). S01printk quiets runtime
kernel messages that would drip onto the PTZ wire. The required
hi3516ev300_lite excludes list prunes every non-imx335 sensor blob,
generated from the live lite image so no entry is stale on arrival.
Dahua-OEM 2 MP camera. The SC223A is on hardware I2C0 routed to the
VI-RAW pads (0x112c0060/0x64 func2) rather than the default mipi-sensor
pads (0x30/0x34 func1) the SDK probes, and needs a 27 MHz MCLK
(0x120100f0=0x19; SDK default 0x11/div4 leaves it unresponsive).
S71devmem re-muxes the pads, selects the SENSOR_RSTN reset (GPIO8_7
func2) and fixes MCLK after S70vendor/load_goke; the stock
open_sensor_i2c then reaches the sensor over /dev/i2c-0. No kernel
module needed.
Verified on hardware: chip-id 0xcb3e over HW I2C0, MIPI lock 1920x1080
zero errors, majestic streams correct colour 1080p.

* Add TP-Link Kasa KC110 (HI3518EV200 + OV2735)
New device variant: hi3518ev200_ultimate_tplink-kasa-kc110.
Contents:
- kc110-board-support package: PTZ binary (mmap'd PL061), gpio-motors
shim for the openipc web GUI, IR control script, and a boot-time
pinmux init that writes 0x1 to the chip7/chip8 pads (0x200f00e8/ec/
f0/fc/100/104). The OpenIPC kernel pinctrl driver does not auto-set
these for the KC110's pan motor / IR-cut / IR-LED pads — the vendor
firmware writes them explicitly in hn_config.sh. Without this,
PL061 GPIODATA writes succeed silently but the pads never drive
the ULN2803 / solenoid / LED.
- Device overlay:
* etc/sensors/ov2735_i2c_1080p.ini — input_mode=0 (MIPI), 1-lane
(was input_mode=4 / 4-lane in upstream cv200 osdrv, which is
wrong for OV2735).
* usr/bin/load_hisilicon — adds an "ov2735" case that mirrors
ov2710_mipi (same MIPI pinmux + clock).
* usr/share/openipc/customizer.sh — first-boot configuration:
RTL8188FU wlandev, sensor config path, IR-cut pin 64, backlight
pin 63, lightMonitor true (AE recovery after IR-cut toggle).
- README.md row.
Hardware notes:
- SoC: Hi3518EV200; Sensor: OV2735 (MIPI 1-lane, RAW10);
Wi-Fi: RTL8188FU (USB); Flash: W25Q128 16 MB NOR.
- PTZ: 4-phase unipolar steppers via ULN2803 darlington array.
Pan = vendor base-10 GPIO 81/74/73/72 = OpenIPC PL061 65/60/59/58;
tilt = 0/1/2/44 = 0/1/2/36 (vendor's "44" is bank 4 pin 4 — i.e.
pin 36 in OpenIPC's PL061 numbering, NOT 44).
- IR-cut filter: GPIO 64 (vendor 80) active-low; IR-LED: GPIO 63
(vendor 77).
Status: PTZ + GPIO + IR fully functional. Video pipeline currently
needs an LD_PRELOAD shim around HI_MIPI_SET_DEV_ATTR because upstream
majestic builds combo_dev_attr_t with enIntfMode=DC / raw_data_type=0
for MIPI sensors that need RAW10. The shim is downstream-only pending
a real fix to majestic upstream; this PR delivers the rest of the
KC110 board support and will produce a fully-functional camera once
the majestic fix lands.

* tplink-kasa-kc110: use ov2735_mipi_1080p.ini
Follow OpenIPC/firmware #2155, which ships the OV2735 MIPI config as a
separate ov2735_mipi_1080p.ini and leaves ov2735_i2c_1080p.ini (the
parallel/DVP config) untouched.
- Rename the device's bundled sensor .ini to ov2735_mipi_1080p.ini and
carry the full corrected MIPI config: input_mode=0 (MIPI),
data_type=2 (RAW10), lane_id 2-lane, Input_mod=5 (MIPI),
Mask_0=0xFFF00000. The previous bundled copy only had input_mode
fixed (data_type/Input_mod/Mask_0 were still the wrong DVP defaults).
- Point customizer.sh's isp.sensorConfig at the new file.
- Exclude the unused parallel ov2735_i2c_1080p.ini from the image.
Verified on a TP-Link Kasa KC110 (OV2735 2-lane MIPI RAW10): clean
image, correct AE, RTSP H.264 1080p.
