While making a spelling mistake myself for `git grep kvalloc` I found that the only file has such a typo. Fix it and update to the standard de facto of how we refer to the functions. Also spell usr-out as user-out, it seems this driver uses its own terminology nobody else can decypher, make it more readable. Signed-off-by:

The Solomon SSD133x controllers (such as the SSD1331) are used by RGB dot matrix OLED panels, add a modesetting pipeline to support the chip family. The SSD133x controllers support 256 (8-bit) and 65k (16-bit) color depths but only the 256-color mode (DRM_FORMAT_RGB332) is implemented for now. Signed-off-by:

inno_hdmi_reset is only ever called when initializing the controller. At this point it’s completely uneccessary to power up the PHY, since all what has to work at this point is the DDC bus. The phy will be powered up correctly when a mode is set in inno_hdmi_encoder_enable and disabled in inno_hdmi_encoder_disable. Set it to LOWER_PWR after resetting the controller. Signed-off-by:

The display controller will always give full range RGB regardless of the mode set, but HDMI requires certain modes to be transmitted in limited range RGB. This is especially required for HDMI sinks which do not support non-standard quantization ranges. This enables color space conversion for those modes and sets the quantization range accordingly in the AVI infoframe. Signed-off-by:

The inno_hdmi driver relies on its own internal infoframe type matching the hardware. This works fine, but in order to make further reworks easier, let's switch to the HDMI spec definition of those types. Signed-off-by:

The code to upload infoframes to the controller uses a weird construct which, based on the previous function call return code, will either disable or enable that infoframe. In order to get rid of that argument, let's split the function to disable the infoframe into a separate function and make it obvious what we are doing in the error path. Signed-off-by:

The tmds_rate field in the inno_hdmi structure is used mostly to configure the internal i2c controller divider through a call to the inno_hdmi_i2c_init() function. We can simply make that rate an argument to that function, which also removes a workaround to initialize the divider at probe time when we don't have a mode yet. Signed-off-by:

The controller wants the difference between *total and *sync_start in the HDMI_VIDEO_EXT_*DELAY registers. Otherwise the signal is very unstable for certain non-VIC modes. See downstream commit [0].

These panels are used by Mediatek MT8173 Chromebooks, and they used to work with the downstream v4.19 kernel without any specified delay. Back in the v4.19 kernel, they used the "little white lie" approach, which is making the devicetree claim a specific panel's compatible string for many different panels. That was a common solution before the generic edp-panel driver. After we uprevved the device to a newer kernel and used the edp-panel driver, we saw multiple devices reporting warnings of using an unknown panel and falling back to the conservative timings, which means that they turn on/off much more slowly than they should. We tried to fill in the timings for those panels, but we failed to find all the data sheets for them. Therefore, instead of having them use the default conservative timings, update them with less-conservative timings from other panels of the same vendor. The panels should still work under those timings, and we can save some delays and suppress the warnings. Signed-off-by:
