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.

drm/bridge: dumb-vga-dac: Rename driver to simple-bridge

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

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.

drm/bridge: Add tc358768 driver

2020-02-10T09:49:49+00:00

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.

Only write is implemented for mipi_dsi_host_ops.transfer.

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.

drm/bridge: sil_sii8620: make remote control optional.

2019-10-10T08:42:15+00:00

commit d6abe6df706c ("drm/bridge: sil_sii8620: do not have a dependency
of RC_CORE") changed the driver to select both RC_CORE and INPUT.
However, this causes problems with other drivers, in particular an input
driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate
commit):

  drivers/clk/Kconfig:9:error: recursive dependency detected!
  drivers/clk/Kconfig:9:        symbol COMMON_CLK is selected by MFD_INTEL_LPSS
  drivers/mfd/Kconfig:566:      symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI
  drivers/mfd/Kconfig:580:      symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI
  drivers/input/keyboard/Kconfig:73:    symbol KEYBOARD_APPLESPI depends on INPUT
  drivers/input/Kconfig:8:      symbol INPUT is selected by DRM_SIL_SII8620
  drivers/gpu/drm/bridge/Kconfig:83:    symbol DRM_SIL_SII8620 depends on DRM_BRIDGE
  drivers/gpu/drm/bridge/Kconfig:1:     symbol DRM_BRIDGE is selected by DRM_PL111
  drivers/gpu/drm/pl111/Kconfig:1:      symbol DRM_PL111 depends on COMMON_CLK

According to the docs and general consensus, select should only be used
for non user-visible symbols, but both RC_CORE and INPUT are
user-visible. Furthermore almost all other references to INPUT
throughout the kernel config are depends, not selects. For this reason
the first part of this change reverts the commit.

In order to address the original reason for the commit, namely
that not all boards use the remote controller functionality and hence
should not need have to deal with RC_CORE, the second part of this
change now makes the remote control support in the driver optional and
contingent on RC_CORE being defined. And with this the hard dependency
on INPUT also goes away as that is only needed if RC_CORE is defined
(which in turn already depends on INPUT).
