phy: hdmi: Add color depth configuration

2025-04-11T11:48:03+00:00

Extend the HDMI configuration options to allow managing bits per color
channel.  This is required by some PHY drivers such as
rockchip-samsung-hdptx.

phy: Add HDMI configuration options

2025-04-11T11:48:03+00:00

Allow HDMI PHYs to be configured through the generic
functions through a custom structure added to the generic union.

The parameters added here are based on HDMI PHY
implementation practices.  The current set of parameters
should cover the potential users.

phy: core: Remove unused phy_pm_runtime_(allow|forbid)

2025-03-10T07:28:07+00:00

phy_pm_runtime_allow() and phy_pm_runtime_forbid() were added in 2013
as part of
commit ff764963479a ("drivers: phy: add generic PHY framework")
but have remained unused.

Remove them.
Fix up the (English) docs - I've left the Chinese translation.

phy: Add Embedded DisplayPort and DisplayPort submodes

2024-03-28T19:00:16+00:00

In some cases, a DP PHY needs to be configured to work in eDP mode.
So add submodes for both DP and eDP so they can be used by the
controllers for specifying the mode the PHY should be configured in.

Merge tag 'usb-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2024-03-21T19:35:20+00:00

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt changes for 6.9-rc1. Lots
  of tiny changes and forward progress to support new hardware and
  better support for existing devices. Included in here are:

   - Thunderbolt (i.e. USB4) updates for newer hardware and uses as more
     people start to use the hardware

   - default USB authentication mode Kconfig and documentation update to
     make it more obvious what is going on

   - USB typec updates and enhancements

   - usual dwc3 driver updates

   - usual xhci driver updates

   - function USB (i.e. gadget) driver updates and additions

   - new device ids for lots of drivers

   - loads of other small updates, full details in the shortlog

  All of these, including a "last minute regression fix" have been in
  linux-next with no reported issues"

phy: tegra: xusb: Add API to retrieve the port number of phy

2024-03-07T20:58:33+00:00

This patch introduces a new API, tegra_xusb_padctl_get_port_number,
to the Tegra XUSB Pad Controller driver. This API is used to identify
the USB port that is associated with a given PHY.

The function takes a PHY pointer for either a USB2 PHY or USB3 PHY as input
and returns the corresponding port number. If the PHY pointer is invalid,
it returns -ENODEV.

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args.  Make the argument
pointer to const for code safety and readability.
