drm: drop _mode_ from update_edit_property()

2018-07-13T16:40:27+00:00

Just makes it longer, and for most things in drm_connector.[hc] we
just use the drm_connector_ prefix. Done with sed + a bit of manual
fixup for the indenting.

drm/panel: simple: Add Sharp LQ035Q7DB03 panel support

2018-07-11T16:35:25+00:00

The change adds support for Sharp LQ035Q7DB03 3.5" QVGA TFT panel.

Note that this aged panel is already found in the kernel sources,
for instance in board mach files mach-mx21ads.c, mach-mx27ads.c,
mach-pcm043.c, lpd270.c and imx27-phytec-phycore-rdk.dts.

drm/panel: type promotion bug in s6e8aa0_read_mtp_id()

2018-07-10T15:59:05+00:00

The ARRAY_SIZE() macro is type size_t.  If s6e8aa0_dcs_read() returns a
negative error code, then "ret < ARRAY_SIZE(id)" is false because the
negative error code is type promoted to a high positive value.

drm/panel: p079zca: Add variable unprepare_delay properties

2018-07-10T15:59:05+00:00

When panel power down, p079zca need delay between reset and disable
power supply, but p097pfg does not need it. Similarly p097zca needs
a delay after entering panel sleep mode. So add two delay properties,
so we can meet these two panel power down sequence.

drm/panel: p079zca: Refactor panel driver to support multiple panels

2018-07-10T15:59:05+00:00

Refactor Innolux P079ZCA panel driver, let it support multi panels from
Innolux that share similar power sequences.

Panels may require different power supplies so use regulator bulk
interfaces and define per panel supply-names.

Changes in v2:
- Change regulator property name to meet the panel datasheet
Changes in v3:
- this patch only refactor P079ZCA panel to support multi panel,
  support P097PFG panel in another patch
Changes in v4:
- Modify the patch which suggest by Thierry
Changes in v5:
- use regulator_bulk to handle different supply number
