As detailed in the thread titled "viafb PLL/clock tweaking causes XO-1.5 instability," enabling or disabling the IGA1/IGA2 clocks causes occasional stability problems during suspend/resume cycles on this platform. This is rather odd, as the documentation suggests that clocks have two states (on/off) and the default (stable) configuration is configured to enable the clock only when it is needed. However, explicitly enabling *or* disabling the clock triggers this system instability, suggesting that there is a 3rd state at play here. Leaving the clock enable/disable registers alone solves this problem. This fixes spurious reboots during suspend/resume behaviour introduced by commit b692a63a. Signed-off-by:

To check channel equalization, the value of LANE_ALIGN_STATUS_UPDATED is necessary in exynos_dp_channel_eq_ok(). Also, link_align includes this value. However, link_status does not include this value, so it makes the problem that channel equalization is failed during link training. Signed-off-by:

It is expected that LCDC to continue to be disabled after resume if it is blanked before suspend. This is also true for DVFS. But it is observed that LCDC being enabled after suspend/resume cycle or DVFS. Correcting it by having check for FB_BLANK_UNBLANK before enabling. Signed-off-by:

Wait for active frame transfer to complete after disabling LCDC. At the same this wait is not be required when there are sync and underflow errors. Patch applies for revision 2 of LCDC present am335x. More information on disable and reset sequence can be found in section 13.4.6 of AM335x TRM @www.ti.com/am335x. Signed-off-by:

the driver's module init and exit functions are calling platform_driver_register and platform_driver_unregister and doing nothing else. This same as that of the module_platform_driver, remove this init and exit functions and use the module_platform_driver instead Signed-off-by:

SW reset sets DP TX to initial value, so configurations for analog parameter and interrupt are not set properly. Therefore, exynos_dp_init_analog_param() and exynos_dp_init_interrupt() should be moved to after sw reset is called, in order to set these values properly. Signed-off-by:

This patch adds adjustement for voltage swing and pre-emphasis during Link Training procedure. According to the DP specification, unless all the LANEx_CR_DONE bits are set, the transmitter must read the ADJUST_REQUEST_LANEx_x, increase the voltage swing according to the request, and update the TRAINING_LANEx_SET bytes to match the new voltage swing setting.

Commit f476ae9d (OMAPDSS: APPLY: Remove DISPC writes to manager's lcd parameters in interface) broke the SDI output, as it causes the SDI PLL locking to fail. LCLK and PCLK divisors are located in shadow registers, and we normally write them to DISPC registers when enabling the output. However, SDI uses pck-free as source clock for its PLL, and pck-free is affected by the divisors. And as we need the PLL before enabling the output, we need to write the divisors early. It seems just writing to the DISPC register is enough, and we don't need to care about the shadow register mechanism for pck-free. The exact reason for this is unknown. Signed-off-by:
