[PATCH v2 0/2] x86: p2sb: P2SB fixes
by Wolfgang Wallner 01 Jul '20

01 Jul '20

Currently it is possible to select the P2SB driver without selecting the P2SB uclass, which can't work. Fix this by adding a "depends on" in Kconfig. While at it, correct the meaning of P2SB (according to Intel's documentation P2SB stands for "Primary to Sideband Bridge"). Remark: I have resent this series as V2 as I had messed up the cover letter in V1. Changes in v3: - Replaced the term in two more places Changes in v2: - Fixed cover letter Wolfgang Wallner (2): drivers: p2sb: replace Primary-to-Sideband Bus with Primary to Sideband Bridge x86: p2sb: make P2SB driver depend on P2SB uclass arch/x86/Kconfig | 1 + drivers/misc/Kconfig | 12 ++++++------ 2 files changed, 7 insertions(+), 6 deletions(-) -- 2.27.0

[PATCH v2] ARM: dts: stm32: add seeed studio odyssey-stm32mp157c board
by Marcin Sloniewski 01 Jul '20

01 Jul '20

This commit adds device tree files supporting SBC from Seeed Studio based on STM32MP157C. This works with generic stm32mp1 config. Right now only booting from SD card is supported. Signed-off-by: Marcin Sloniewski <marcin.sloniewski(a)gmail.com> --- Changes in v2: - removed `st,adc_usb_pd` from config since that adc connection is non-existent which caused warning or hang during boot arch/arm/dts/Makefile | 3 +- .../dts/odyssey-stm32mp157c-som-u-boot.dtsi | 134 +++++++ arch/arm/dts/odyssey-stm32mp157c-som.dtsi | 364 ++++++++++++++++++ arch/arm/dts/odyssey-stm32mp157c-u-boot.dtsi | 64 +++ arch/arm/dts/odyssey-stm32mp157c.dts | 161 ++++++++ 5 files changed, 725 insertions(+), 1 deletion(-) create mode 100644 arch/arm/dts/odyssey-stm32mp157c-som-u-boot.dtsi create mode 100644 arch/arm/dts/odyssey-stm32mp157c-som.dtsi create mode 100644 arch/arm/dts/odyssey-stm32mp157c-u-boot.dtsi create mode 100644 arch/arm/dts/odyssey-stm32mp157c.dts diff --git a/arch/arm/dts/Makefile b/arch/arm/dts/Makefile index 9900b44274..dd617c7188 100644 --- a/arch/arm/dts/Makefile +++ b/arch/arm/dts/Makefile @@ -918,7 +918,8 @@ dtb-$(CONFIG_STM32MP15x) += \ stm32mp157c-ed1.dtb \ stm32mp157c-ev1.dtb \ stm32mp15xx-dhcom-pdk2.dtb \ - stm32mp15xx-dhcor-avenger96.dtb + stm32mp15xx-dhcor-avenger96.dtb \ + odyssey-stm32mp157c.dtb dtb-$(CONFIG_SOC_K3_AM6) += k3-am654-base-board.dtb k3-am654-r5-base-board.dtb dtb-$(CONFIG_SOC_K3_J721E) += k3-j721e-common-proc-board.dtb \ diff --git a/arch/arm/dts/odyssey-stm32mp157c-som-u-boot.dtsi b/arch/arm/dts/odyssey-stm32mp157c-som-u-boot.dtsi new file mode 100644 index 0000000000..cf08efae09 --- /dev/null +++ b/arch/arm/dts/odyssey-stm32mp157c-som-u-boot.dtsi @@ -0,0 +1,134 @@ +// SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause +/* + * Copyright (C) 2020 Marcin Sloniewski <marcin.sloniewski(a)gmail.com> + */ + +#include <dt-bindings/clock/stm32mp1-clksrc.h> +#include "stm32mp15-u-boot.dtsi" +#include "stm32mp15-ddr3-1x4Gb-1066-binG.dtsi" + +/ { + config { + u-boot,boot-led = "heartbeat";

[PATCH v2 0/2] x86: p2sb: P2SB fixes
by Wolfgang Wallner 01 Jul '20

01 Jul '20

Currently it is possible to select the P2SB driver without selecting the P2SB uclass, which can't work. Fix this by adding a "depends on" in Kconfig. While at it, correct the meaning of P2SB (according to Intel's documentation P2SB stands for "Primary to Sideband Bridge"). Remark: I have resent this series as V2 as I had messed up the cover letter in V1. Changes in v2: - Fixed cover letter Wolfgang Wallner (2): drivers: p2sb: replace Primary-to-Sideband Bus with Primary to Sideband Bridge x86: p2sb: make P2SB driver depend on P2SB uclass arch/x86/Kconfig | 1 + drivers/misc/Kconfig | 8 ++++---- 2 files changed, 5 insertions(+), 4 deletions(-) -- 2.27.0

[RFC PATCH v3 0/6] Improve USB Keyboard support for rpi3/rpi4
by Jason Wessel 01 Jul '20

01 Jul '20

At this point all the USB keyboards I had laying around now work and I can USB boot the rpi3 and rpi4, so perhaps this series can move beyond the RFC stage. More testing will occur over the next week or so. v3: - Add in patch 6 - Finally got the GearHead keyboard + mouse composite USB device working v2: - Minor cleanups to patches 1-3 based on prior review - Patch 4 & 5 are new to fix various xhchi crashes while having additional devices plugged in along with booting off the usb port. The nonblocking mode turned out to be somewhat complex. v1: For testing this patch series, I did apply the USB patches for the rpi4 board which had not been merged yet. Once the rpi4 USB changes are eventually merged the keyboard delay issues will show up and I imagine this issue is already a problem for other boards. This series does not depend on rpi4 patches as the changes are in the core USB functions. I performed tests with a number of usb modules attached including storage, ethernet, serial, wifi, keyboard, and mouse without any issues. ---------------------------------------------------------------- Jason Wessel (6): xhci: Add polling support for USB keyboards usb_kbd: Do not fail the keyboard if it does not have an interrupt pending common/usb.c: Work around keyboard reporting "USB device not accepting new address" xhci-ring.c: Add the poll_pend state to properly abort transactions xhci-ring: Fix crash when issuing "usb reset" usb.c: Add a retry in the usb_prepare_device() common/usb.c | 18 +++++++++--- common/usb_kbd.c | 4 ++- drivers/usb/host/xhci-ring.c | 123 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++------------------ drivers/usb/host/xhci.c | 11 ++++---- include/usb/xhci.h | 5 ++-- 5 files changed, 122 insertions(+), 39 deletions(-)
