[PATCH 1/5] drm/i915/vlv_dsi: Add DMI quirk for wrong panel modeline in BIOS on Asus TF103C (v2)

[Hans de Goede]

Vtotal is wrong in the BIOS supplied modeline for the DSI panel on
the Asus TF103C leading to the last line of the display being shown
as the first line.

Original: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 820 0x8 0xa
Fixed:    "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 816 0x8 0xa

The factory installed Android has a hardcoded modeline in its kernel,
causing it to not suffer from this BIOS bug;
and the Android boot-splash which uses the EFI FB which does have this bug
has the last line all black causing the bug to not be visible.

This commit introduces a generic DMI based quirk mechanism to vlv_dsi for
doing various fixups, and uses this to correct the modeline.

v2:
- s/mode_fixup/dmi_quirk/ to make the new DMI quirk mechanism more generic
- Add a comment with the old and new modelines to the patch and commit msg

[PATCH 2/5] drm/i915/vlv_dsi: Add DMI quirk for wrong panel size on Lenovo Yoga Tablet 2 series

[Hans de Goede]

On the Lenovo Yoga Tablet 2 830 / 1050 the VBT contains a bogus
192mm x 120mm size. This is especially a problem on the 8" 830 version
which uses a 10:16 portrait screen where as the bogus size is 16:10.

Add a DMI quirk to override the wrong panel size with the correct one.
Note both the 10" 1050 models as well as the 8" 830 models use the same
mainboard and thus the same DMI strings. The 10" 1050 uses a 1920x1200
landscape screen, where as the 8" 830 uses a 1200x1920 portrait screen,
so the quirk handling uses the display resolution to detect the model.

[PATCH 4/5] drm/i915/dsi: Skip MIPI I2C sequences if not listed as a I2cSerialBus resource

[Hans de Goede]

The current mipi_exec_i2c code uses 2 methods to find the I2C bus / adapter
to use:

1) Search for an ACPI I2cSerialBus resource matching the client address
from the MIPI sequence

2) Fall back to searching the adapter by the I2C bus number from the MIPI
sequence if 1) fails.

1 is fine, 2 however is problematic Linux does not have a fixed enumeration
order for I2C busses, so Linux numbers don't necessary line up with the
VBT numbers. On the Lenovo Yoga Tablet 2 830/1050 this causes these errors:

i2c_designware 80860F41:03: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (169)
i2c_designware 80860F41:03: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (165)
i2c_designware 80860F41:03: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (167)

Fix these errors by turning mipi_exec_i2c calls into no-ops if there is
no matching ACPI I2cSerialBus resource, restoring the behavior from before
the current mipi_exec_i2c implementation. This change should not cause any
issues because:

1) Most DSDT correctly list an I2cSerialBus resource matching the client
VBT MIPI sequence address, so we never hit scenario 2.

2) The current mipi_exec_i2c implementation was added to fix a backlight
issue on an Aava Mobile's Inari 10 tablet, which is Bay Trail based. Most
BYT based devices have worked fine with a no-op implementation of
mipi_exec_i2c since 2014.

[Intel-gfx] [PATCH 4/5] drm/i915/dsi: Skip MIPI I2C sequences if not listed as a I2cSerialBus resource

[Hans de Goede]

The current mipi_exec_i2c code uses 2 methods to find the I2C bus / adapter
to use:

1) Search for an ACPI I2cSerialBus resource matching the client address
from the MIPI sequence

2) Fall back to searching the adapter by the I2C bus number from the MIPI
sequence if 1) fails.

1 is fine, 2 however is problematic Linux does not have a fixed enumeration
order for I2C busses, so Linux numbers don't necessary line up with the
VBT numbers. On the Lenovo Yoga Tablet 2 830/1050 this causes these errors:

i2c_designware 80860F41:03: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (169)
i2c_designware 80860F41:03: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (165)
i2c_designware 80860F41:03: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (167)

Fix these errors by turning mipi_exec_i2c calls into no-ops if there is
no matching ACPI I2cSerialBus resource, restoring the behavior from before
the current mipi_exec_i2c implementation. This change should not cause any
issues because:

1) Most DSDT correctly list an I2cSerialBus resource matching the client
VBT MIPI sequence address, so we never hit scenario 2.

2) The current mipi_exec_i2c implementation was added to fix a backlight
issue on an Aava Mobile's Inari 10 tablet, which is Bay Trail based. Most
BYT based devices have worked fine with a no-op implementation of
mipi_exec_i2c since 2014.

[PATCH 5/5] drm/i915/vlv_dsi: Skip MIPI I2C sequences on Microsoft Surface 3

[Hans de Goede]

The VBT DSI MIPI sequences of the panel on the Microsoft Surface 3
contain a couple of I2c writes to what seems to be a non existing
TI LP855x backlight controller, leading to the following errors:

i915 0000:00:02.0: [drm] mipi_exec_i2c bus 5 client-addr 0x2c reg 0x01 data 01
i2c_designware 808622C1:04: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (1)
i915 0000:00:02.0: [drm] mipi_exec_i2c bus 5 client-addr 0x2c reg 0x16 data 07
i2c_designware 808622C1:04: controller timed out
i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (22)

Besides these errors this also causes the screen turning on to be delayed
by 2 seconds. At a DMI based quirk to ignore VBT DSI MIPI I2C writes on
the Microsoft Surface 3.
