[PATCH 0/4] Move Mediatek HDMI PHY driver from DRM folder to PHY folder

[Chun-Kuang Hu]

mtk_hdmi_phy is currently placed inside mediatek drm driver, but it's
more suitable to place a phy driver into phy driver folder, so move
mtk_hdmi_phy driver into phy driver folder.

[PATCH 1/4] drm/mediatek: Move tz_disabled from mtk_hdmi_phy to mtk_hdmi driver

[Chun-Kuang Hu]

From: CK Hu <ck.hu@mediatek.com>

tz_disabled is used to control mtk_hdmi output signal, but this variable
is stored in mtk_hdmi_phy and mtk_hdmi_phy does not use it. So move
tz_disabled to mtk_hdmi where it's used.

[PATCH 2/4] drm/mediatek: Separate mtk_hdmi_phy to an independent module

[Chun-Kuang Hu]

From: CK Hu <ck.hu@mediatek.com>

mtk_hdmi_phy is a part of mtk_hdmi module, but phy driver should be an
independent module rather than be part of drm module, so separate the phy
driver to an independent module.
