novatek: pad-mux, reginfo and GPIO for NA51089 (#237)

novatek: pad-mux, reginfo and GPIO for NA51089 (#237) (#239)

Support for NT98562/NT98566 (NA51089) landed in #239. It will be in the next latest build of ipctool.

No Novatek board was available to test on, so a run on yours would be the first hardware check. Please post the output of these four commands:

ipctool reginfo
ipctool reginfo --pads
cat /proc/nvt_info/nvt_pinmux/pinmux_summary
cat /proc/nvt_info/nvt_pinmux/chip_id

pinmux_summary is the kernel's own decode of the same registers. Comparing it with --pads is how we find out whether the table is right.

gpio get/set/scan and gpio mux now work too. Pads are given as the Linux GPIO number (54) or the kernel's name (P_GPIO22).

A follow-up, #240, is merged as well. On your NT98566 it adds the LCD pins, so pads used by a panel now read as LCD_* rather than unclaimed. The same build also covers NT9852x and NT98528/NT98529.

The request above still stands. The output of these commands from your camera would be the first hardware check of these tables:

ipctool reginfo
ipctool reginfo --pads
cat /proc/nvt_info/nvt_pinmux/pinmux_summary
cat /proc/nvt_info/nvt_pinmux/chip_id

Thank you, this is exactly what was needed. Your NT98566 output agrees with the kernel's own pinmux_summary on every pad:

`pinmux_summary`	meaning	`reginfo --pads`
`nand 0x4`	SPI NAND	C_GPIO0-3, 8, 10 = `FSPI_*`
`sensor 0x220`	MIPI + MCLK	S_GPIO0 = `SENSOR_MCLK`
`mipi_lvds 0xf01`	CLK0 + DAT0..3	H_GPIO0-9 = MIPI lanes; H10/11 GPIO
`i2c 0x51`	CH1, CH2, CH3	S7/S8, S4/S5, P22/P21
`uart 0xa5`	UART, UART2, UART3 on its 2nd location	P23/24, P17/18, C21/22
`pwm 0x4200000`	PWM8_2, PWM9_2	C_GPIO19/20
`pwm2 0x210`	PWM4_5, PWM5_5	DSI_GPIO4/5
`lcd 0x10000000`	location only, no panel	all LCD pads GPIO
`eth 0x22`	internal PHY, LED2	D_GPIO5/6 = `ETH_LED2`
`misc 0x22`	SP clocks off	—

Every pad shown as carrying something is one the kernel configured, and every one it configured reads correctly. The raw gate bitmaps in reginfo agree too: for example, CGPIO 0x7faf0 has exactly bits 0-3, 8, 10 and 19-22 clear. That makes NA51089 the first Novatek die verified on hardware.

If you have a minute, ipctool gpio scan while you toggle day/night mode in the web UI would also check the GPIO controller side. That is optional; the pad-mux side is done.

docs: NA51089 pad-mux verified on hardware (#237) (#242)

ipctool gpio search
and
ioctool gpio set p_gpio8 1

works yet

Thanks! I read "works yet" as "already works" (уже работает). If you meant "doesn't work yet", please say so and paste what it printed.

Two notes:

There is no gpio search subcommand; with one it prints the usage. I assume you ran gpio scan.
To record the GPIO side as verified, I'd like the output itself, checked against something that isn't ipctool. On your board P_GPIO8 is Linux GPIO 40 (0x20 + 8):

ipctool gpio set P_GPIO8 1
ipctool gpio get P_GPIO8
cat /sys/kernel/debug/gpio | grep -i -E "gpio-40 |gpio40"   # if debugfs is mounted
ipctool gpio set P_GPIO8 0
ipctool gpio get P_GPIO8

From gpio scan, the first lines and any --> change lines you see while toggling day/night mode in the web UI would also help. If day/night changes a pad, that pad is the IR-cut, and its number is what possible ircut should report.

работает. и работает правильно.
с децимальной нумерацией в стоке группы и пины совпадают.

Спасибо! Отмечу в документации, что GPIO (gpio set/get/scan) на NT98566 работает и нумерация совпадает со стоковой прошивкой.

Thanks! I'll note in the docs that GPIO (gpio set/get/scan) works on the NT98566 and its numbering matches the stock firmware.
