drm/panel: panel-innolux: set display off in innolux_panel_unprepare

2019-04-20T07:16:04+00:00

[ Upstream commit 46f3ceaffa81e846677bca8668e0ad40e643cffd ] Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable() to innolux_panel_unprepare(), so they are consistent with innolux_panel_enable() and innolux_panel_prepare(). This also fixes some mode check and irq timeout issue in MTK dsi code. Since some dsi code (e.g. mtk_dsi) have following call trace: 1. drm_panel_disable(), which calls innolux_panel_disable() 2. switch to cmd mode 3. drm_panel_unprepare(), which calls innolux_panel_unprepare() However, mtk_dsi needs to be in cmd mode to be able to send commands (e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()), so we need these functions to be called after the switch to cmd mode happens, i.e. in innolux_panel_unprepare.

drm: drop _mode_ from update_edit_property()

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.

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.

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.
