Add support for the video pattern generator (VPG) BER pattern mode and configuration in runtime. This enables using the debugfs interface to manipulate the VPG after the pipeline is set. Also, enables the usage of the VPG BER pattern.

Current code enables the HS clock when video mode is started or to send out a HS command, and disables the HS clock to send out a LP command. This is not what DSI spec specify. Enable HS clock either in command and in video mode. Set automatic HS clock management for panels and devices that support non-continuous HS clock.

Current code does not properly computes the max length of LP commands that can be send during H or V sync, and rely on static values. Limiting the max LP length to 4 byte during the V-sync is overly conservative. Relax the limit and allows longer LP commands (16 bytes) to be sent during V-sync.

The upstream S6E63M0 driver has some peculiarities around the prepare/enable disable/unprepare sequence: the screen is taken out of sleep in prepare() as part of s6e63m0_init() the put to on with MIPI_DCS_SET_DISPLAY_ON in enable(). However it is just put into sleep mode directly in disable(). As disable()/enable() can be called without unprepare()/prepare() being called, this is unbalanced, we should take the display out of sleep in enable() then turn it off(). Further MIPI_DCS_SET_DISPLAY_OFF is never called balanced with MIPI_DCS_SET_DISPLAY_ON. The vendor driver for Samsung GT-I8190 (Golden) does all of these things in strict order. Augment the driver to do exit sleep/set display on in enable() and set display off/enter sleep in disable(). Further send an explicit reset pulse in power_on() so we come up in a known state, and issue the MCS_ERROR_CHECK command after setting display on like the vendor driver does. Also use the timings from the vendor driver in the sequence. Doing all of these things makes the display much more stable on the Samsung GT-I8190 when enabling/disabling the display pipeline.

This panel can be accessed using both SPI and DSI. To make it possible to probe and use the device also from a DSI bus, first break out the SPI support to its own file. Since all the panel driver does is write DCS commands to the panel, we pass a DCS write function to probe() from each subdriver. We make the Kconfig entry for SPI mode default so all current users will continue to work.

Following functions are only used internally, not by drivers: - devm_drm_dev_init Also, now that we have a very slick and polished way to allocate a drm_device with devm_drm_dev_alloc, update all the docs to reflect the new reality. Mostly this consists of deleting old and misleading hints. Two main ones: - it is no longer required that the drm_device base class is first in the structure. devm_drm_dev_alloc can cope with it being anywhere - obviously embedded now strongly recommends using devm_drm_dev_alloc v2: Fix typos (Noralf) v3: Split out the removal of drm_dev_init, that's blocked on some discussions on how to convert vgem/vkms/i915-selftests.

In order to shrink drm_display_mode below the magic two cacheline mark in 64bit we need to shrink it by another 8 bytes. The easiest thing to eliminate is the 'export_head' list head which is only used during the getconnector ioctl to temporarly track which modes on the connector's mode list are to be exposed and which are to remain hidden. We can simply replace the list head with a boolean which we use to tag the modes that are to be exposed. If we make sure to clear the tags after we're done with them we don't even need an extra loop over the modes to reset the tags at the start of the getconnector ioctl. Conveniently we already have a hole for the boolean left behind by the removal of mode->private_flags. The final size of the struct is now 112 bytes on 32bit and 120 bytes on 64bit. Another alternative would be a temp bitmask so we wouldn't have to have anything in the mode struct itself. The main issue is how large of a bitmask do we need? I guess we could allocate it dynamically but that means an extra kcalloc() and an extra loop through the modes to count them first (or grow the bitmask with krealloc() as needed).

For DP MST outputs, the i2c device currently only supports transfers that can be implemented using remote i2c reads. Such transfers must consist of zero or more write transactions followed by one read transaction. DDC/CI commands require standalone write transactions and hence aren't supported. Since each remote i2c write is handled as a separate transfer, remote i2c writes can support transfers consisting of write transactions, where all but the last have I2C_M_STOP set. According to the DDC/CI 1.1 standard, DDC/CI commands only require a single write or read transaction in a transfer, so this is sufficient. For i2c transfers meeting the above criteria, generate and send a remote i2c write message for each transaction. Add the trivial remote i2c write reply parsing support so remote i2c write acks bubble up correctly.

Initial value of vblank time is zero and hrtimer.node.expires is also zero if vblank aren't enabled before. vkms module isn't real hardware but just virtual hardware module. so vkms can't generate a resonable timestamp when hrtimer is off. it's best to grab the current time.

The VKMS blend function was ignoring the alpha channel and just overwriting vaddr_src with vaddr_dst. This XRGB approach triggers a warning when running the kms_cursor_crc/cursor-alpha-transparent test case. In IGT, cairo_format_argb32 uses premultiplied alpha (according to documentation). Also current DRM assumption is that alpha is premultiplied. Therefore, this patch considers premultiplied alpha blending eq to compose vaddr_src with vaddr_dst. This change removes the following cursor-alpha-transparent warning: "Suspicious CRC: All values are 0."

The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels.

Print an error message inside ps8640_bridge_vdo_control() function when it fails so we can simplify a bit the callers, they will only need to check the error code.

Bridge drivers that implement the new model only shall return an error from their attach() handler when the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is not set. So make sure we return an error because only the new drm_bridge model is supported.
