treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

drm/bridge: chrontel-ch7033: Add a new driver

2020-05-05T07:48:56+00:00

This is a driver for video encoder with VGA and DVI/HDMI outputs.

There is no documentation for the chip -- the operation was guessed from
what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names
come from the ch7035 driver in Mediatek's GPL code dump.

Only bare minimum is implemented -- no fancy stuff, such as scaling. That
would only worsen our misery. We don't load the firmware and we don't need
to even bother enabling the MCU.  There are probably no distributable
firmware images anyway.

Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60,
with VGA as well as DVI.

drm/bridge: Add NWL MIPI DSI host controller support

2020-04-09T13:52:47+00:00

This adds initial support for the NWL MIPI DSI Host controller found on
i.MX8 SoCs.

It adds support for the i.MX8MQ but the same IP can be found on
e.g. the i.MX8QXP.

It has been tested on the Librem 5 devkit using mxsfb.

drm/bridge: Add driver for the TI TPD12S015 HDMI level shifter

2020-02-26T11:31:38+00:00

The TI TPD12S015 is an HDMI level shifter and ESD protector controlled
through GPIOs. Add a DRM bridge driver for the device.

drm/bridge: Add bridge driver for display connectors

2020-02-26T11:31:37+00:00

Display connectors are modelled in DT as a device node, but have so far
been handled manually in several bridge drivers. This resulted in
duplicate code in several bridge drivers, with slightly different (and
thus confusing) logics.

In order to fix this, implement a bridge driver for display connectors.
The driver centralises logic for the DVI, HDMI, VGAn composite and
S-video connectors and exposes corresponding bridge operations.

This driver in itself doesn't solve the issue completely, changes in
bridge and display controller drivers are needed to make use of the new
connector driver.

The dumb-vga-dac driver can support simple DRM bridges without being
limited to VGA DACs. Rename it to simple-bridge.

drm/bridge: sii902x: Select SND_SOC_HDMI_CODEC if SND_SOC is configured

2020-02-10T09:54:59+00:00

To enable HDMI audio the SND_SOC_HDMI_CODEC needs to be
configured. Enable HDMI audio by selecting SND_SOC_HDMI_CODEC if
SND_SOC is configured. SND_SOC_HDMI_CODEC has no config menu entry and
should be selected automatically by the drivers using it.

Add basic support for the Toshiba TC358768 RGB to DSI bridge.
Not all the features of the TC358768 is implemented by the initial driver:
MIPI_DSI_MODE_VIDEO and MIPI_DSI_FMT_RGB888 is only supported and tested.

drm/bridge: Repurpose lvds-encoder.c

2019-12-18T11:26:07+00:00

lvds-encoder.c implementation is also suitable for LVDS decoders,
not just LVDS encoders.
Instead of creating a new driver for addressing support for
transparent LVDS decoders, repurpose lvds-encoder.c for the greater
good with this patch.

This patch only "rebrands" the lvds-encoder.c driver, to make it
suitable for hosting LVDS decoders support. The actual support for
LVDS decoders will come with a later patch.
