+Subject: [PATCH 056/194] BCM2708: Add core Device Tree support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add the bare minimum needed to boot BCM2708 from a Device Tree.

+BCM2708: DT: change 'axi' nodename to 'soc'
+
+Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
+The VC4 bootloader fills in certain properties in the 'axi' subtree,
+but since this is part of an upstreaming effort, the name is changed.

+
+BCM2708_DT: Correct length of the peripheral space
+
+Use dts-dirs feature for overlays.
+
+The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
+
+Using this fixes the install_dtbs target, which previously did not install the overlays.

+
+BCM270X_DT: switch to bcm2835-i2s
+
+I2S soundcard drivers with proper devicetree support (i.e. not linking
+to the cpu_dai/platform via name but to cpu/platform via of_node)
+will work out of the box without any modifications.
+
+When the kernel is compiled without devicetree support the platform
+code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
+will link to it via name, as before.

+SDIO-overlay: add poll_once-boolean parameter

+
+BCM270X_DT: Make mmc overlay compatible with current firmware
+
+The original DT overlay logic followed a merge-then-patch procedure,
+i.e. parameters are applied to the loaded overlay before the overlay
+is merged into the base DTB. This sequence has been changed to
+patch-then-merge, in order to support parameterised node names, and
+to protect against bad overlays. As a result, overrides (parameters)
+must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
+
+mmc-overlay.dts (that switches back to the original mmc sdcard
+driver) is the only overlay violating that rule, and this patch
+fixes it.
+
+bcm270x_dt: Use the sdhost MMC controller by default
+
+The "mmc" overlay reverts to using the other controller.
+
+squash: Add cprman to dt
+
+BCM270X_DT: Use clk_core for I2C interfaces
+
+BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
+
+The mainline Device Tree files are quite close to downstream now.
+Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
+for our dts files.
+
+Mainline dts files are based on these files:
+
+ bcm2835-rpi.dtsi
+ bcm2835.dtsi bcm2836.dtsi
+ bcm283x.dtsi
+
+Current downstream are based on these:
+
+ bcm2708.dtsi bcm2709.dtsi bcm2710.dtsi
+ bcm2708_common.dtsi
+
+This patch introduces this dependency:
+
+ bcm2708.dtsi bcm2709.dtsi
+ bcm2708-rpi.dtsi
+ bcm270x.dtsi
+ bcm2835.dtsi bcm2836.dtsi
+ bcm283x.dtsi
+
+And:
+ bcm2710.dtsi
+ bcm2708-rpi.dtsi
+ bcm270x.dtsi
+ bcm283x.dtsi
+
+bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
+bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
+
+Other changes:
+- The led node has moved from /soc/leds to /leds. This is not a problem
+ since the label is used to reference it.
+- The clk_osc reg property changes from 6 to 3.
+- The gpu nodes has their interrupt property set in the base file.
+- the clocks label does not point to the /clocks node anymore, but
+ points to the cprman node. This is not a problem since the overlays
+ that use the clock node refer to it directly: target-path = "/clocks";
+- some nodes now have 2 labels since mainline and downstream differs in
+ this respect: cprman/clocks, spi0/spi, gpu/vc4.
+- some nodes doesn't have an explicit status = "okay" since they're not
+ disabled in the base file: watchdog and random.
+- gpiomem doesn't need an explicit status = "okay".
+- bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
+ it's now set directly in that file.
+- bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
+- Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

+BCM270X_DT: Don't generate "linux,phandle" props
+
+The EPAPR standard says to use "phandle" properties to store phandles,
+rather than the deprecated "linux,phandle" version. By default, dtc
+generates both, but adding "-H epapr" causes it to only generate
+"phandle"s, saving some space and clutter.

+BCM270X_DT: Add midi-uart0 overlay
+
+MIDI requires 31.25kbaud, a baudrate unsupported by Linux. The
+midi-uart0 overlay configures uart0 (ttyAMA0) to use a fake clock
+so that requesting 38.4kbaud actually gets 31.25kbaud.

++Introduction
++============
++
++This directory contains Device Tree overlays. Device Tree makes it possible
++to support many hardware configurations with a single kernel and without the
++need to explicitly load or blacklist kernel modules. Note that this isn't a
++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
++are still configured by the board support code, but the intention is to
++eventually reach that goal.
++
++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
++default, the Raspberry Pi kernel boots with device tree enabled. You can
++completely disable DT usage (for now) by adding:
++
++ device_tree=
++
++to your config.txt, which should cause your Pi to revert to the old way of
++doing things after a reboot.
++
++In /boot you will find a .dtb for each base platform. This describes the
++hardware that is part of the Raspberry Pi board. The loader (start.elf and its
++siblings) selects the .dtb file appropriate for the platform by name, and reads
++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
++are disabled, but they can be enabled using Device Tree parameters:
++
++ dtparam=i2c=on,i2s=on,spi=on
++
++However, this shouldn't be necessary in many use cases because loading an
++overlay that requires one of those interfaces will cause it to be enabled
++automatically, and it is advisable to only enable interfaces if they are
++needed.
++
++Configuring additional, optional hardware is done using Device Tree overlays
++(see below).
++
++GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
++not the physical pin numbers.
++
++raspi-config
++============
++
++The Advanced Options section of the raspi-config utility can enable and disable
++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
++is possible to both enable an interface and blacklist the driver, if for some
++reason you should want to defer the loading.
++
++Modules
++=======
++
++As well as describing the hardware, Device Tree also gives enough information
++to allow suitable driver modules to be located and loaded, with the corollary
++that unneeded modules are not loaded. As a result it should be possible to
++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
++have its contents deleted (or commented out).
++
++Using Overlays
++==============
++
++Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
++by writing a magic string comprising a device identifier and an I2C address to
++a special file in /sys/class/i2c-adapter, having first loaded the driver for
++the I2C interface and the RTC device - something like this:
++
++ modprobe i2c-bcm2835
++ modprobe rtc-ds1307
++ echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
++
++With DT enabled, this becomes a line in config.txt:
++
++ dtoverlay=i2c-rtc,ds1307
++
++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
++default it usees address 0x68, but this can be modified with an additional DT
++parameter:
++
++ dtoverlay=i2c-rtc,ds1307,addr=0x68
++
++Parameters usually have default values, although certain parameters are
++mandatory. See the list of overlays below for a description of the parameters
++and their defaults.
++
++The Overlay and Parameter Reference
++===================================
++
++N.B. When editing this file, please preserve the indentation levels to make it
++simple to parse programmatically. NO HARD TABS.
++
++
++Name: <The base DTB>

++ compatible devices (default "on"). See also
++ "tx_lpi_timer".
++
++ eth_downshift_after Set the number of auto-negotiation failures

++ Legal values are 2, 3, 4, 5 and 0, where
++ 0 means never downshift (default 2).
++
++ eth_led0 Set mode of LED0 (usually orange) (default
++ "1"). The legal values are:
++ 0=link/activity 1=link1000/activity
++ 2=link100/activity 3=link10/activity
++ 4=link100/1000/activity 5=link10/1000/activity
++ 6=link10/100/activity 14=off 15=on
++
++ eth_led1 Set mode of LED1 (usually green) (default
++ "6"). See eth_led0 for legal values.
++
++ eth_max_speed Set the maximum speed a link is allowed
++ to negotiate. Legal values are 10, 100 and
++ 1000 (default 1000).
++
++ i2c_arm Set to "on" to enable the ARM's i2c interface
++ (default "off")
++
++ i2c_vc Set to "on" to enable the i2c interface
++ usually reserved for the VideoCore processor
++ (default "off")
++
++ i2c An alias for i2c_arm
++
++ i2c_arm_baudrate Set the baudrate of the ARM's i2c interface
++ (default "100000")
++
++ i2c_vc_baudrate Set the baudrate of the VideoCore i2c interface
++ (default "100000")
++
++ i2c_baudrate An alias for i2c_arm_baudrate
++
++ i2s Set to "on" to enable the i2s interface
++ (default "off")
++
++ spi Set to "on" to enable the spi interfaces
++ (default "off")
++
++ random Set to "on" to enable the hardware random
++ number generator (default "on")
++
++ sd_overclock Clock (in MHz) to use when the MMC framework
++ requests 50MHz
++
++ sd_force_pio Disable DMA support for SD driver (default off)
++
++ sd_pio_limit Number of blocks above which to use DMA for
++ SD card (default 1)
++
++ sd_debug Enable debug output from SD driver (default off)
++
++ sdio_overclock Clock (in MHz) to use when the MMC framework
++ requests 50MHz for the SDIO/WiFi interface.
++
++ tx_lpi_timer Set the delay in microseconds between going idle
++ and entering the low power state (default 600).
++ Requires EEE to be enabled - see "eee".
++
++ uart0 Set to "off" to disable uart0 (default "on")
++
++ uart1 Set to "on" or "off" to enable or disable uart1
++ (default varies)
++
++ watchdog Set to "on" to enable the hardware watchdog
++ (default "off")
++
++ act_led_trigger Choose which activity the LED tracks.
++ Use "heartbeat" for a nice load indicator.
++ (default "mmc")
++
++ act_led_activelow Set to "on" to invert the sense of the LED
++ (default "off")
++ N.B. For Pi3 see pi3-act-led overlay.
++
++ act_led_gpio Set which GPIO to use for the activity LED
++ (in case you want to connect it to an external
++ device)
++ (default "16" on a non-Plus board, "47" on a
++ Plus or Pi 2)
++ N.B. For Pi3 see pi3-act-led overlay.
++
++ pwr_led_trigger
++ pwr_led_activelow
++ pwr_led_gpio
++ As for act_led_*, but using the PWR LED.
++ Not available on Model A/B boards.
++
++ N.B. It is recommended to only enable those interfaces that are needed.
++ Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
++ interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
++ Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
++ interfaces i2c0 and i2c1. Use of the numeric variants is still possible
++ but deprecated because the ARM/VC assignments differ between board
++ revisions. The same board-specific mapping applies to i2c_baudrate,
++ and the other i2c baudrate parameters.
