Subject: [PATCH v3 1/2] dt-bindings: input: touchscreen: Add 'goodix-hold-in-reset' property to Goodix
Date: Thu, 16 Mar 2023 16:47:50 +0100	[thread overview]
Message-ID: <20230316154749.68304-1-jajadekroon@gmail.com> (raw)
In-Reply-To: <20230311134655.486973-1-jajadekroon@gmail.com>

Add an optional 'goodix-hold-in-reset', to the Goodix touchscreen
device tree binding. When set to true, the touchscreen controller will
be held in reset mode during system suspend, reducing power consumption.
If not present, the property defaults to false.

Signed-off-by: Jan Jasper de Kroon <jajadekroon@gmail.com>

Changes from v2 to v3:
- Used imperative mood instead of "This patch adds".
- Dropped "I am submitting this patch to..." as it is redundant.
- Removed the paragraph related to the related patch sent to the 
  linux-input mailing list as it is not necessary.
- Renamed the hold-in-reset-in-suspend function to 
  goodix-hold-in-reset to prevent potential naming conflicts with other 
  functions in the codebase. No functional changes were made.

Changes from v1 to v2:
- Updated subject prefix to match subsystem.
- Added more detailed description of the change.
- Fixed formatting issues in commit message.
