* | | drm/bridge: it6505: fix HDCP encryption when R0 readyHermes Wu2025-01-031-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When starting HDCP authentication, HDCP encryption should be enabled when R0'is checked. Change encryption enables time at R0' ready. The hardware HDCP engine trigger is changed and the repeater KSV fails will restart HDCP.

* | | drm/bridge: it6505: add AUX operation for HDCP KSV list readHermes Wu2025-01-031-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDCP KSV list readback can choose to use AUX FIFO or general data register. For some DisplayPort devices, the KSV list must be read in 5 byte boundaries. The original AUX read command does not support these devices. The AUX command operation control register "REG_AUX_CMD_REQ" uses b[3:0] as AUX operacion control, and b[7:4] are status bits and read only. To change KSV read operation uses "CMD_AUX_NATIVE_READ" from using the data registers to using AUX FIFO. The extended command "CMD_AUX_GET_KSV_LIST" is added as "CMD_AUX_NATIVE_READ" with the 0x10 flag which selects AUX FIFO mode.

This should not be static as this depends mainly on the connected display voltage requirement. We have three properties: - "ti,lvds-termination-ohms", which sets near end termination, - "ti,lvds-vod-swing-data-microvolt" and - "ti,lvds-vod-swing-clock-microvolt" which both set LVDS differential output voltage for data and clock lanes. They are defined as an array with min and max values. The appropriate bitfield will be set if selected constraints can be met. If "ti,lvds-termination-ohms" is not defined the default of 200 Ohm near end termination will be used. Selecting only one: "ti,lvds-vod-swing-data-microvolt" or "ti,lvds-vod-swing-clock-microvolt" can be done, but the output voltage constraint for only data/clock lanes will be met. Setting both is recommended.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IT6505 bridge chip has a active low reset line. Since it is a "reset" and not an "enable" line, the GPIO should be asserted to put it in reset and deasserted to bring it out of reset during the power on sequence. The polarity was inverted when the driver was first introduced, likely because the device family that was targeted had an inverting level shifter on the reset line. The MT8186 Corsola devices already have the IT6505 in their device tree, but the whole display pipeline is actually disabled and won't be enabled until some remaining issues are sorted out. The other known user is the MT8183 Kukui / Jacuzzi family; their device trees currently do not have the IT6505 included. Fix the polarity in the driver while there are no actual users.

* | | | | drm/bridge: lt9611: use HDMI Connector helper to set InfoFramesDmitry Baryshkov2024-10-122-55/+120

Program InfoFrames using the helper's callbacks. Also use TMDS char rate validation callback to filter out modes, instead of hardcoding 4k@30. The Audio InfoFrame isn't yet handled by these helpers, it requires additional drm_bridge interface changes.
