[PATCH v4 5/5] iio: accel: mc3230: add mc3510c support

From: Vasiliy Doylov via B4 Relay
Date: Mon Jan 13 2025 - 09:03:22 EST


From: Vasiliy Doylov <nekodevelopper@xxxxxxxxx>

This change integrates mc3510c support into the mc3230 driver.
MC3510C uses the same registers as MC3230, but a different value scale.

Tested on Huawei MediaPad T3 10 (huawei-agassi)
