spacewar: 6.17 rebase #14

fekz115 · 2025-10-11T17:00:37Z

Here is actual changes for nothing-spacewar. I created this PR as we have plan to merge our pmaports to postmarketos upstream.

new focaltech driver wip, but actually working
wcd938x driver wip, microphone doesn't work
sony imx471 works
samsung s5kjn1 works
tfa987x (tfa9873) works as driver allows(no TPM and other features)

DW9800 is a 10 bit DAC from Dongwoon, designed for linear control of voice coil motor. This driver creates a V4L2 subdevice and provides control to set the desired focus. Signed-off-by: Vitalii Skorkin <nikroksm@mail.ru>

Add support for ak7377 VCM, which has 10-bit position values, requiring a shift of 6 bits. It also has a different standby mode setting (0x10 instead of 0x40) and a significantly longer control delay. The maximum focus position is 1023, and the control step count is increased to 100. Tested on sm7325-nothing-spacewar phone. Signed-off-by: Danila Tikhonov <danila@jiaxyga.com>

It appears to sometimes take longer than two seconds for the tx_sdw_dev to appear, to increase the timeout. Signed-off-by: Luca Weiss <luca.weiss@fairphone.com>

…r from DS This is some preparation for rewriting the driver: - Drop downstream pinctrl, point report check, gesture, pen, ESD, drm notifier implementation - Drop unused code - Drop old firmware files - Switch to tabs in main files - Refactor regulators & reset gpio implementation - Drop FTS macros & use kernel log func calls - And other minor changes...

Can you guard this under of_machine_is_compatible("nothing,spacewar")?

I assume https://lore.kernel.org/linux-arm-msm/20251001135914.13754-3-caojunjie650@gmail.com/ would be the proper fix? Do you know anything about that?

drivers/media/i2c/Kconfig

Please try if dongwoon,dw9800k (on the lists, but also in sc7280 6.17.y branch) works instead? Then we can drop this custom dw9800 driver.

drivers/media/i2c/ak7375.c

Hm, not sure if this version or https://lore.kernel.org/linux-arm-msm/20251009-ak7377-driver-v1-2-29e4f6e16ed3@fairphone.com/ is more correct. Do you have any extra insights there?

@JIaxyga Do you have any input here?

I've fixed this with https://lore.kernel.org/linux-arm-msm/20250930-sc7280-dts-misc-v1-5-5a45923ef705@fairphone.com/, can drop this from sm7325.dtsi

this is already disabled in sc7280.dtsi?

I'm unsure whether all this stuff, not just dmic should go into sm7325.dtsi or into the device itself.

It's per-se not really sm7325-specific, when an SM7325 device gets an Android 16 upgrade (looks like the Nothing phone 1 is already basically EOL, wtf?) the ADSP firmware from my understanding should be doing Audioreach instead of Elite, no q6afecc anymore. This opens a whole other can of worms, so not sure...
