2014-11-24drm/exynos: dsi: set TE GPIO IRQ status as IRQ_NOAUTOENYoungJun Cho1-8/+5
The exynos_dsi_te_irq_handler() works only dsi(DPMS) is on. So it is enough to enable and disable TE GPIO IRQ in exynos_dsi_enable(disable)_irq() like DSI IRQ.

2014-11-24drm/exynos: dsi: move TE irq handler registration positionYoungJun Cho1-3/+3
The drm_helper_hpd_irq_event() does dpms control and the panel is initialized and displayed on by it. So the exynos_dsi_te_irq_handler() should be registered beforehand.

2014-11-24drm/exynos: dsi: move DSIM_STATE_ENABLED set positionYoungJun Cho1-2/+3
The command mode panel should draw image earlier than the display on command execution to prevent showing garbage GRAM screen data. So should set dsi->state as DSIM_STATE_ENABLED between calling exynos_dsi_set_display_enable() and drm_panel_enable() to transmit image data before executing display on command. And moves the display on command execution routine from prepare() to enable() in drm_panel_funcs also.

2014-11-24drm/exynos: dsi: remove global variable exynos_dsi_displayAndrzej Hajda1-20/+18
exynos_dsi_display is used by internal Exynos DRM framework for representing pair encoder->connecter. As it should be mapped 1:1 to dsi private context it seems more reasonable to embed it directly in that context. As a result further code simplification will be possible. Moreover it will be possible to handle multiple DSI devices in the system. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2014-09-20drm/exynos: mipi-dsi: consider non-continuous clock modeInki Dae1-0/+19
This patch adds non-continuous clock mode support Clock mode on Clock Lane is continuous clock by default. So if we want to transmit data in non-continuous clock mode to reduce power consumption, then host driver should set DSIM_CLKLANE_STOP bit. In this case, host controller turns off HS clock between high speed transmissions. For this, this patch adds a new bit, DSIM_CLKLANE_STOP, and makes the host driver sets this bit only in case that dsi->mode_flags has MIPI_DSI_CLOCK_NON_CONTINUOUS flag.

drm/panel: Changes for v3.17-rc1 Panels can now be more finely controlled via .prepare() and .unprepare() callbacks in addition to .enable() and .disable(). New kerneldoc details what they are supposed to do and when they should be called. The simple panel driver gained support for a couple of new panels and it is now possible to specify additional delays during power up and power down sequences if panels require it. DSI devices can now advertise that they support non-continuous clock mode which will allow DSI host controllers to disable the high speed clock after transmissions to save power. * tag 'drm/panel/for-3.17-rc1' of git://anongit.freedesktop.org/tegra/linux: (30 commits) drm/panel: simple: Use devm_gpiod_get_optional() drm/dsi: Replace upcasting macro by function drm/panel: ld9040: Replace upcasting macro by function drm/exynos: dp: Modify driver to support drm_panel drm/exynos: Move DP setup into commit() drm/panel: simple: Add AUO B133HTN01 panel support drm/panel: simple: Support delays in panel functions drm/panel: simple: Add proper definition for prepare and unprepare drm/panel: s6e8aa0: Add proper definition for prepare and unprepare drm/panel: ld9040: Add proper definition for prepare and unprepare drm/tegra: Add support for panel prepare and unprepare routines drm/exynos: dsi: Add support for panel prepare and unprepare routines drm/exynos: dpi: Add support for panel prepare and unprepare routines drm/panel: simple: Add dummy prepare and unprepare routines drm/panel: s6e8aa0: Add dummy prepare and unprepare routines drm/panel: ld9040: Add dummy prepare and unprepare routines drm/panel: Provide convenience wrapper for .get_modes() drm/panel: add .prepare() and .unprepare() functions drm/panel: simple: Remove simple-panel compatible drm/panel: simple: Add Innolux N116BGE panel support ...

This reverts commit d089621896c3530a9bd309f96e9c9124d07f6c3f was original to prevent multiple MODULE_DEVICE_TABLE in one module. Which, as a side-effect broke autoloading of the module. Since 21bdd17b21b45ea48e06e23918d681afbe0622e9 it is possible to have multiple calls to MODULE_DEVICE_TABLE, so the patch can be reverted to restore support for autoloading Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>

The offset of register DSIM_PLLTMR_REG in Exynos5410 / 5420 / 5440 SoCs is different from the one in Exynos4 SoCs. In case of Exynos5410 / 5420 / 5440 SoCs, there is no frequency band bit in DSIM_PLLCTRL_REG, and it uses DSIM_PHYCTRL_REG and DSIM_PHYTIMING*_REG instead.

2014-08-03drm/exynos: dsi: add TE interrupt handler to support LCD I80 interfaceYoungJun Cho1-2/+96
This is a temporary solution and should be made by more generic way. To support LCD I80 interface, the DSI host should register TE interrupt handler from the TE GPIO of attached panel. So the panel generates a tearing effect synchronization signal then the DSI host calls the CRTC device manager to trigger to transfer video image.

This patch makes sure that exynos drm framework handles deferred probe case correctly. Sub drivers could be probed before resources, clock, regulator, phy or panel, are ready for them so we should make sure that exynos drm core waits until all resources are ready and sub drivers are probed correctly.
