Drivers: video: remove __dev* attributes.

2013-01-03T23:57:01Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Signed-off-by: Greg Kroah-Hartman

2012-11-29T01:33:28Z

INT_CTL register contains bits INT_POL0 and INT_POL1, and not INT_POL. This patch fixes the wrong register setting for INT_CTL. Signed-off-by: Ajay Kumar Signed-off-by: Jingoo Han

video: exynos_dp: Reset and initialize DP before requesting irq

2012-11-29T01:33:28Z

If DP is not reset properly before kernel bootup(in bootloader code), there can be few pending interrupts, and sometimes they invoke DP irq handler as soon as the irq handler is registered in DP probe. So, we make the DP driver more robust by resetting and initializing DP at the earliest and then registering the irq handler. Signed-off-by: Ajay Kumar Signed-off-by: Jingoo Han

video: exynos_dp: Enable hotplug interrupts

2012-11-29T01:33:28Z

Enable hotplug interrupts and move the hotplug scheduling into the interrupt handler. This allows us to introduce a screen at any time while we're running.

video: exynos_dp: Move hotplug into a workqueue

2012-11-29T01:33:28Z

Move the hotplug related code from probe and resume into a workqueue. This allows us to initialize the DP driver (and resume it) when there is no monitor connected. Signed-off-by: Sean Paul Reviewed-by: Olof Johansson Signed-off-by: Jingoo Han

video: exynos_dp: Improve EDID error handling

2012-11-29T01:33:27Z

EDID error handling has 2 problems: - It doesn't fail as early as it can - The retry counts for i2c and aux transactions are huge This patch fails if the initial i2c transaction fails, and reduces the aux and i2c retry counts down to 3.

According to the exynos datasheet (Figure 49-10), we should wait for PLL lock before programming the training pattern when doing software eDP link training. Signed-off-by: Sean Paul Signed-off-by: Jingoo Han
