[PATCH v2 1/1] staging: greybus: Remove completed PWM TODO item.

by Sammy Malik

The pwm.c driver already uses pwm_ops::apply. This item was completed in commit 832ce36f44a2 ("staging: greybus: introduce pwm_ops::apply") but never removed from the TODO list.

[PATCH 0/3] staging: greybus: arche-platform: fix probe issues

by Johan Hovold

This series fixes some issues with the arche platform drivers probe function. A fix for the first issue was sent to the list two months ago, but there has been no reply to the review feedback given then. Non of these are tagged for stable backport as very few people should have the hardware in question and be bothered by this.

[PATCH 00/14] greybus: introduce CPC as transport layer

by Damien Riégel

Hi, This patchset brings support for Silicon Labs' Co-Processor Communication (CPC) protocol as transport layer for Greybus. This is introduced as a module that sits between Greybus and CPC Host Device Drivers implementations, like SDIO or SPI. This patchset includes SDIO as physical layer but the protocol is not final and might change, it's mostly there to showcase all the elements. +----------------------------------------------------+ | Greybus | +----------------------------------------------------+ /|\ | \|/ +----------------------------------------------------+ | CPC | +----------------------------------------------------+ /|\ /|\ /|\ | | | \|/ \|/ \|/ +----------+ +---------+ +-----------+ | SDIO | | SPI | | Others | +----------+ +---------+ +-----------+ CPC implements some of the features of Unipro that Greybus relies upon, like reliable transmission. CPC takes care of detecting transmission errors and retransmit frames if necessary, but that feature is not part of the RFC to keep it concise. There's also a flow-control feature, preventing sending messages to already full cports. In order to implement these features, a 4-byte header is prepended to Greybus messages, making the whole header 12 bytes (Greybus header itself is 8 bytes). This RFC starts by implementing a shim layer between physical bus drivers (like SDIO and SPI) and Greybus, and progressively add more elements to it to make it useful in its own right. Finally, an SDIO driver is added to enable the communication with a remote device. Changes since the RFC: - added missing Signed-off-by on one commit - added SDIO driver to give a full example Damien Riégel (13): greybus: cpc: add minimal CPC Host Device infrastructure greybus: cpc: introduce CPC cport structure greybus: cpc: use socket buffers instead of gb_message in TX path greybus: cpc: pack cport ID in Greybus header greybus: cpc: switch RX path to socket buffers greybus: cpc: introduce CPC header structure greybus: cpc: account for CPC header size in RX and TX path greybus: cpc: add and validate sequence numbers greybus: cpc: acknowledge all incoming messages greybus: cpc: use holding queue instead of sending out immediately greybus: cpc: honour remote's RX window greybus: cpc: let host device drivers dequeue TX frames greybus: cpc: add private data pointer in CPC Host Device Gabriel Beaulieu (1): greybus: cpc: add CPC SDIO host driver MAINTAINERS | 6 + drivers/greybus/Kconfig | 2 + drivers/greybus/Makefile | 2 + drivers/greybus/cpc/Kconfig | 22 ++ drivers/greybus/cpc/Makefile | 9 + drivers/greybus/cpc/cpc.h | 75 +++++ drivers/greybus/cpc/cport.c | 107 +++++++ drivers/greybus/cpc/header.c | 146 +++++++++ drivers/greybus/cpc/header.h | 55 ++++ drivers/greybus/cpc/host.c | 313 +++++++++++++++++++ drivers/greybus/cpc/host.h | 63 ++++ drivers/greybus/cpc/protocol.c | 167 ++++++++++ drivers/greybus/cpc/sdio.c | 554 +++++++++++++++++++++++++++++++++ 13 files changed, 1521 insertions(+) create mode 100644 drivers/greybus/cpc/Kconfig create mode 100644 drivers/greybus/cpc/Makefile create mode 100644 drivers/greybus/cpc/cpc.h create mode 100644 drivers/greybus/cpc/cport.c create mode 100644 drivers/greybus/cpc/header.c create mode 100644 drivers/greybus/cpc/header.h create mode 100644 drivers/greybus/cpc/host.c create mode 100644 drivers/greybus/cpc/host.h create mode 100644 drivers/greybus/cpc/protocol.c create mode 100644 drivers/greybus/cpc/sdio.c -- 2.49.0

[PATCH] greybus: Use bus methods for .probe() and .remove()

by Uwe Kleine-König

These are nearly identical to the respective driver callbacks. The only difference is that .remove() returns void instead of int. The objective is to get rid of users of struct device_driver callbacks .probe() and .remove() to eventually remove these.

[PATCH v6] staging: greybus: arche-apb-ctrl: switch to device_property_read_bool

by Julio Cesar Carvalho de Paula Souza

Switch from the deprecated of_property_read_bool() to the common device_property_read_bool() API. This makes the driver agnostic to the underlying firmware interface (DT or ACPI) and simplifies the logic. Since the driver is no longer strictly dependent on Device Tree, include <linux/mod_devicetable.h> directly for the struct of_device_id definition, instead of relying on implicit inclusion via <linux/of_irq.h>, which has been removed as it is unused. Also rename apb_ctrl_get_devtree_data() to apb_ctrl_get_fw_data() to better reflect the agnostic nature of the new implementation.
