Subject: [PATCH v3 0/3] QCOM QUP I2C - Add noise rejection, convert to YAML
Date: Thu, 14 Jan 2021 19:04:12 +0100	[thread overview]
Message-ID: <20210114180415.404418-1-angelogioacchino.delregno@somainline.org> (raw)

This patch series converts the i2c-qup bindings to YAML and then
adds support for noise rejection, which is needed for some noisy
hardware, like the touchscreen on the F(x)Tec Pro1.
After adding noise rejection, the touchscreen stopped showing
ghost touch issues and lockups.

Tested on F(x)Tec Pro1 (MSM8998).

Changes in v3, as per Bjorn's review:
 - Moved bitfield.h to maintain sort order
 - Removed useless variable initialization
 - Removed linebreak

Changes in v2:
 - Fixed ARM (32) build error (added bitfield.h inclusion)
