open-drain warnings - -The i2c-gpio driver expects to use a GPIO in open-drain mode. Failure -to configure it in that way causes alarming warnings in the kernel log. -The BCM283x and BCM2711 GPIO blocks don't support open-drain mode, -but i2c-gpio works anyway. Silence the warning by declaring that -open-drain mode has been enabled by other means. - -See: https://github.com/raspberrypi/firmware/issues/1381 - -Signed-off-by: Phil Elwell <phil@raspberrypi.com>

Strong pull up is also applied during +the required time, according to device power status needs and +'strong_pullup' module parameter. + +'temperature_from_RAM()' function is introduced to get the correct +temperature computation (device dependent) from device RAM data. + +An new sysfs entry has been added to ouptut only temperature.

Unicam receives CSI-2 or +- * CCP2 data and writes it into SDRAM. +- * The only potential processing options are to repack Bayer data into an +- * alternate format, and applying windowing. +- * The repacking does not shift the data, so can repack V4L2_PIX_FMT_Sxxxx10P +- * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12, +- * but not generically up to V4L2_PIX_FMT_Sxxxx16.

Fully processed frames are +- * delivered to the driver by the firmware. It only has sensor drivers +- * for Omnivision OV5647, and Sony IMX219 sensors. +- * +- * The two drivers are mutually exclusive for the same Unicam instance. +- * The VideoCore firmware checks the device tree configuration during boot. +- * If it finds device tree nodes called csi0 or csi1 it will block the +- * firmware from accessing the peripheral, and bcm2835-camera will +- * not be able to stream data. +- */ +- +-#include <linux/clk.h> +-#include <linux/delay.h> +-#include <linux/device.h> +-#include <linux/dma-mapping.h> +-#include <linux/err.h> +-#include <linux/init.h> +-#include <linux/interrupt.h> +-#include <linux/io.h> +-#include <linux/module.h> +-#include <linux/of_device.h> +-#include <linux/of_graph.h> +-#include <linux/pinctrl/consumer.h> +-#include <linux/platform_device.h> +-#include <linux/pm_runtime.h> +-#include <linux/slab.h> +-#include <linux/uaccess.h> +-#include <linux/videodev2.h> +- +-#include <media/v4l2-common.h> +-#include <media/v4l2-ctrls.h> +-#include <media/v4l2-dev.h> +-#include <media/v4l2-device.h> +-#include <media/v4l2-dv-timings.h> +-#include <media/v4l2-event.h> +-#include <media/v4l2-ioctl.h> +-#include <media/v4l2-fwnode.h> +-#include <media/videobuf2-dma-contig.h> +- +-#include "vc4-regs-unicam.h" +- +-#define UNICAM_MODULE_NAME "unicam" +-#define UNICAM_VERSION "0.1.0" +- +-static int debug; +-module_param(debug, int, 0644); +-MODULE_PARM_DESC(debug, "Debug level 0-3"); +- +-#define unicam_dbg(level, dev, fmt, arg...) \ +- v4l2_dbg(level, debug, &(dev)->v4l2_dev, fmt, ##arg) +-#define unicam_info(dev, fmt, arg...) \ +- v4l2_info(&(dev)->v4l2_dev, fmt, ##arg) +-#define unicam_err(dev, fmt, arg...) \ +- v4l2_err(&(dev)->v4l2_dev, fmt, ##arg) +- +-/* To protect against a dodgy sensor driver never returning an error from +- * enum_mbus_code, set a maximum index value to be used. +- */ +-#define MAX_ENUM_MBUS_CODE 128 +- +-/* +- * Stride is a 16 bit register, but also has to be a multiple of 32. +- */ +-#define BPL_ALIGNMENT 32 +-#define MAX_BYTESPERLINE ((1 << 16) - BPL_ALIGNMENT) +-/* +- * Max width is therefore determined by the max stride divided by +- * the number of bits per pixel.

It's disabled by default and can be enabled by +`krnbt=on` parameter of the miniuart-bt overlay. + +Signed-off-by: Maxim Mikityanskiy <maxtram95@gmail.com> +--- + arch/arm/boot/dts/bcm2708-rpi-bt.dtsi | 26 +++++++++++++++++++ + arch/arm/boot/dts/bcm2708-rpi-zero-w.dts | 1 + + arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts | 1 + + arch/arm/boot/dts/bcm2710-rpi-3-b.dts | 1 + + arch/arm/boot/dts/bcm2711-rpi-4-b.dts | 3 +-- + arch/arm/boot/dts/bcm271x-rpi-bt.dtsi | 26 +++++++++++++++++++ + arch/arm/boot/dts/overlays/README | 12 +++++++-- + .../boot/dts/overlays/disable-bt-overlay.dts | 13 ++++++++-- + .../boot/dts/overlays/miniuart-bt-overlay.dts | 21 ++++++++++++--- + 9 files changed, 94 insertions(+), 10 deletions(-) + create mode 100644 arch/arm/boot/dts/bcm2708-rpi-bt.dtsi + create mode 100644 arch/arm/boot/dts/bcm271x-rpi-bt.dtsi + +--- /dev/null ++++ b/arch/arm/boot/dts/bcm2708-rpi-bt.dtsi +@@ -0,0 +1,26 @@ ++// SPDX-License-Identifier: GPL-2.0 ++ ++&uart0 { ++ bt: bluetooth { ++ compatible = "brcm,bcm43438-bt"; ++ max-speed = <3000000>; ++ shutdown-gpios = <&gpio 45 GPIO_ACTIVE_HIGH>; ++ status = "disabled"; ++ }; ++}; ++ ++&uart1 { ++ minibt: bluetooth { ++ compatible = "brcm,bcm43438-bt"; ++ max-speed = <460800>; ++ shutdown-gpios = <&gpio 45 GPIO_ACTIVE_HIGH>; ++ status = "disabled"; ++ }; ++}; ++ ++/ { ++ __overrides__ { ++ krnbt = <&bt>,"status"; ++ krnbt_baudrate = <&bt>,"max-speed:0"; ++ }; ++}; +--- a/arch/arm/boot/dts/bcm2708-rpi-zero-w.dts ++++ b/arch/arm/boot/dts/bcm2708-rpi-zero-w.dts +@@ -4,6 +4,7 @@ + #include "bcm2708-rpi.dtsi" + #include "bcm283x-rpi-csi1-2lane.dtsi" + #include "bcm283x-rpi-i2c0mux_0_28.dtsi" ++#include "bcm2708-rpi-bt.dtsi" + + / { + compatible = "raspberrypi,model-zero-w", "brcm,bcm2835"; +--- a/arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts ++++ b/arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts +@@ -5,6 +5,7 @@ + #include "bcm283x-rpi-lan7515.dtsi" + #include "bcm283x-rpi-csi1-2lane.dtsi" + #include "bcm283x-rpi-i2c0mux_0_44.dtsi" ++#include "bcm271x-rpi-bt.dtsi" + + / { + compatible = "raspberrypi,3-model-b-plus", "brcm,bcm2837"; +--- a/arch/arm/boot/dts/bcm2710-rpi-3-b.dts ++++ b/arch/arm/boot/dts/bcm2710-rpi-3-b.dts +@@ -5,6 +5,7 @@ + #include "bcm283x-rpi-smsc9514.dtsi" + #include "bcm283x-rpi-csi1-2lane.dtsi" + #include "bcm283x-rpi-i2c0mux_0_44.dtsi" ++#include "bcm271x-rpi-bt.dtsi" + + / { + compatible = "raspberrypi,3-model-b", "brcm,bcm2837"; +--- a/arch/arm/boot/dts/bcm2711-rpi-4-b.dts ++++ b/arch/arm/boot/dts/bcm2711-rpi-4-b.dts +@@ -182,6 +182,7 @@ + // Downstream rpi- changes + + #include "bcm270x.dtsi" ++#include "bcm271x-rpi-bt.dtsi" + + / { + soc { +@@ -250,8 +251,6 @@ + &uart0 { + pinctrl-0 = <&uart0_pins &bt_pins>; + status = "okay"; +- +- /delete-node/ bluetooth; + }; + + &uart1 { +--- /dev/null ++++ b/arch/arm/boot/dts/bcm271x-rpi-bt.dtsi +@@ -0,0 +1,26 @@ ++// SPDX-License-Identifier: GPL-2.0 ++ ++&uart0 { ++ bt: bluetooth { ++ compatible = "brcm,bcm43438-bt"; ++ max-speed = <3000000>; ++ shutdown-gpios = <&expgpio 0 GPIO_ACTIVE_HIGH>; ++ status = "disabled"; ++ }; ++}; ++ ++&uart1 { ++ minibt: bluetooth { ++ compatible = "brcm,bcm43438-bt"; ++ max-speed = <460800>; ++ shutdown-gpios = <&expgpio 0 GPIO_ACTIVE_HIGH>; ++ status = "disabled"; ++ }; ++}; ++ ++/ { ++ __overrides__ { ++ krnbt = <&bt>,"status"; ++ krnbt_baudrate = <&bt>,"max-speed:0"; ++ }; ++}; +--- a/arch/arm/boot/dts/overlays/README ++++ b/arch/arm/boot/dts/overlays/README +@@ -162,6 +162,13 @@ Params: + i2s Set to "on" to enable the i2s interface + (default "off") + ++ krnbt Set to "on" to enable autoprobing of Bluetooth ++ driver without need of hciattach/btattach ++ (default "off") ++ ++ krnbt_baudrate Set the baudrate of the PL011 UART when used ++ with krnbt=on ++ + spi Set to "on" to enable the spi interfaces + (default "off") + +@@ -1764,8 +1771,9 @@ Info: Switch the onboard Bluetooth fun + in which case use /dev/serial1 instead because it will always be + correct.

Its IRQ driver assumes that's still the case when the +kernel boots and does not perform any initialization of the registers. +However the Raspberry Pi Foundation's bootloader leaves the USB +interrupt enabled when handing over control to the kernel. + +Quiesce IRQs and the FIQ if they were left enabled and log a message to +let users know that they should update the bootloader once a fixed +version is released. + +If the USB interrupt is not quiesced and the USB driver later on claims +the FIQ (as it does on the Raspberry Pi Foundation's downstream kernel), +interrupt latency for all other peripherals increases and occasional +lockups occur. That's because both the FIQ and the normal USB interrupt +fire simultaneously: + +On a multicore Raspberry Pi, if normal interrupts are routed to CPU 0 +and the FIQ to CPU 1 (hardcoded in the Foundation's kernel), then a USB +interrupt causes CPU 0 to spin in bcm2836_chained_handle_irq() until the +FIQ on CPU 1 has cleared it. Other peripherals' interrupts are starved +as long. I've seen CPU 0 blocked for up to 2.9 msec. eMMC throughput +on a Compute Module 3 irregularly dips to 23.0 MB/s without this commit +but remains relatively constant at 23.5 MB/s with this commit. + +The lockups occur when CPU 0 receives a USB interrupt while holding a +lock which CPU 1 is trying to acquire while the FIQ is temporarily +disabled on CPU 1.

I had a whitescreen but no obvious errors when using 'sudo vcdbg log msg' or 'dmesg'. Both /dev/fb0 and /dev/fb1 were present. Followed this article on waveshare32b that 'reset_gpios needed to be 0 0 1 instead of 0 0 0' (https://forum.armbian.com/topic/13233-any-clues-for-the-creation-of-a-dtoverlay-for-fbtft-on-54y/). I applied a similar change to this dts file and compiled a new dtbo: 'dtc -O dtb -o hy28b.dtbo hy28b-overlay.dts'. Fixed my issue - may help others?

A +recent kernel change introduces a reasonable possibility that the +GET call doesn't completes, and bisecting led to a commit from +October that changes the timer usage of the mailbox. + +My theory is that there is a race condition in the new code that breaks +the poll timer, but that it normally goes unnoticed because subsequent +mailbox activity wakes it up again. The power-off mailbox calls happen +at a time when other subsystems have been shut down, so if one of them +fails then there is nothing to allow it to recover. + +Revert 6dc15642 as (at least) a workaround. + +See: https://github.com/raspberrypi/linux/issues/3941 + +Signed-off-by: Phil Elwell <phil@raspberrypi.com> +--- + drivers/mailbox/mailbox.c | 12 +++++------- + 1 file changed, 5 insertions(+), 7 deletions(-) + +--- a/drivers/mailbox/mailbox.c ++++ b/drivers/mailbox/mailbox.c +@@ -82,12 +82,9 @@ static void msg_submit(struct mbox_chan + exit: + spin_unlock_irqrestore(&chan->lock, flags);
