Subject: [PATCH v6 4/5] phy: rockchip-typec: support variable phy config value
Date:   Mon, 21 May 2018 17:37:03 +0800
Message-Id: <1526895424-22894-4-git-send-email-hl@rock-chips.com>
In-Reply-To: <1526895424-22894-1-git-send-email-hl@rock-chips.com>
References: <1526895424-22894-1-git-send-email-hl@rock-chips.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

the phy config values used to fix in dp firmware, but some boards
need change these values to do training and get the better eye diagram
result. So support that in phy driver.

---
Changes in v2:
- update patch following Enric suggest
Changes in v3:
- delete need_software_training variable
- add default phy config value, if dts do not define phy config value, use these value
Changes in v4:
- rename variable config to tcphy_default_config
Changes in v5:
- None
Changes in v6:
- split the header file to new patch
