Add support for the GPIO controller employed by Realtek in multiple series of
MIPS SoCs. These include the supported RTL838x and RTL839x. The register layout
also matches the one found in the GPIO controller of other (Lexra-based) SoCs
such as RTL8196E, RTL8197D, and RTL8197F.
For the platform
Realtek MIPS SoCs (platform name Otto) have GPIO controllers with up to
64 GPIOs, divided over two banks. Each bank has a set of registers for
32 GPIOs, with support for edge-triggered interrupts.
Each GPIO bank consists of four 8-bit GPIO ports (ABCD and EFGH). Most
registers pack one bit per

Firstly, there is no VC_EN bit present in the STREAM_DATA_CFG register.
Bit 31 is part of the VL_SELECT field. Remove it completely.
Secondly, it makes little sense to enable ith virtual channel for ith
stream. Sure, there might be a use-case that demands it. But there might
also be a use case
The stream stop procedure says that the STOP bit should be set when the
stream is to be stopped, and then the ready bit in stream status
register polled to make sure the STOP operation is finished.

Some platforms like TI's J721E can have the CSI2RX paired with an
external DPHY. Add support to enable and configure the DPHY using the
generic PHY framework.
Get the pixel rate and bpp from the subdev and pass them on to the DPHY
along with the number of lanes. All other settings are left to
This resets the stream state machines and FIFOs, giving them a clean
slate. On J721E if the streams are not reset before starting the
capture, the captured frame gets wrapped around vertically on every run
after the first.

The Cadence DPHY can be used to receive image data over the CSI-2
protocol. Add support for Rx mode. The programming sequence differs from
the Tx mode so it is added as a separate set of hooks to isolate the two
paths.
The PHY is in Tx mode by default and it needs to be set in Rx mode by
setting
Hi,
This series adds support for CSI2 capture on J721E. It includes some
fixes to the Cadence CSI2RX driver, adds Rx support to Cadence DPHY
driver, and finally adds the TI CSI2RX wrapper driver.
Tested on TI's J721E with OV5640 sensor.

Allow callers to set the PHY mode. The main mode should always be
PHY_MODE_MIPI_DPHY but the submode can either be
PHY_MIPI_DPHY_SUBMODE_RX or PHY_MIPI_DPHY_SUBMODE_TX. Update the ops
based on the requested submode.

It is, but in this situation, the controller is sending a second
completion that results in a use-after-free, which makes the
transport irrelevant. Unless there is some other flow (which is
unclear
to me) that causes this which is a bug that needs to be fixed rather
than hidden with a
The Rx programming sequence differs from the Tx programming sequence.
Currently only Tx mode is supported. Move all the Tx related parts into
a set of Tx-specific hooks that are then called by the main PHY
framework hooks. This way when Rx support is added all that is needed to
be done is to plug
From: Paul Kocialkowski
As some D-PHY controllers support both Rx and Tx mode, we need a way for
users to explicitly request one or the other. For instance, Rx mode can
be used along with MIPI CSI-2 while Tx mode can be used with MIPI DSI.
Introduce new MIPI D-PHY PHY submodes to use with

This is not upstream, why not squash in. Also would make sense to write
sensible changelog and not phrases and use the right subsystem
conventions!

Hi Linus,
please pull a couple of small updates for s390.
Thanks,

All get_fs/set_fs calls in MIPS code are gone, so remove implementation
of it. With the clear separation of user/kernel space access we no
longer need the EVA special handling, so get rid of that, too.

Use new __get_data macro to access user/kernel for functions, which
are used with user/kernel pointers. Instead of dealing with get_fs/set_fs
this macro uses a parameter to select user/kernel access.
