13 BCM2708: DT: change 'axi' nodename to 'soc'
14
15 Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
16 The VC4 bootloader fills in certain properties in the 'axi' subtree,
17 but since this is part of an upstreaming effort, the name is changed.

21 BCM2708_DT: Correct length of the peripheral space
22
23 Use dts-dirs feature for overlays.
24
25 The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
26
27 Using this fixes the install_dtbs target, which previously did not install the overlays.

33 BCM270X_DT: switch to bcm2835-i2s
34
35 I2S soundcard drivers with proper devicetree support (i.e. not linking
36 to the cpu_dai/platform via name but to cpu/platform via of_node)
37 will work out of the box without any modifications.
38
39 When the kernel is compiled without devicetree support the platform
40 code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
41 will link to it via name, as before.

52 BCM270X_DT: Make mmc overlay compatible with current firmware
53
54 The original DT overlay logic followed a merge-then-patch procedure,
55 i.e. parameters are applied to the loaded overlay before the overlay
56 is merged into the base DTB. This sequence has been changed to
57 patch-then-merge, in order to support parameterised node names, and
58 to protect against bad overlays. As a result, overrides (parameters)
59 must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
60
61 mmc-overlay.dts (that switches back to the original mmc sdcard
62 driver) is the only overlay violating that rule, and this patch
63 fixes it.
64
65 bcm270x_dt: Use the sdhost MMC controller by default
66
67 The "mmc" overlay reverts to using the other controller.
68
69 squash: Add cprman to dt
70
71 BCM270X_DT: Use clk_core for I2C interfaces
72
73 BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
74
75 The mainline Device Tree files are quite close to downstream now.
76 Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
77 for our dts files.
78
79 Mainline dts files are based on these files:
80
81 bcm2835-rpi.dtsi
82 bcm2835.dtsi bcm2836.dtsi
83 bcm283x.dtsi
84
85 Current downstream are based on these:
86
87 bcm2708.dtsi bcm2709.dtsi bcm2710.dtsi
88 bcm2708_common.dtsi
89
90 This patch introduces this dependency:
91
92 bcm2708.dtsi bcm2709.dtsi
93 bcm2708-rpi.dtsi
94 bcm270x.dtsi
95 bcm2835.dtsi bcm2836.dtsi
96 bcm283x.dtsi
97
98 And:
99 bcm2710.dtsi
100 bcm2708-rpi.dtsi
101 bcm270x.dtsi
102 bcm283x.dtsi
103
104 bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
105 bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
106
107 Other changes:
108 - The led node has moved from /soc/leds to /leds. This is not a problem
109 since the label is used to reference it.
110 - The clk_osc reg property changes from 6 to 3.
111 - The gpu nodes has their interrupt property set in the base file.
112 - the clocks label does not point to the /clocks node anymore, but
113 points to the cprman node. This is not a problem since the overlays
114 that use the clock node refer to it directly: target-path = "/clocks";
115 - some nodes now have 2 labels since mainline and downstream differs in
116 this respect: cprman/clocks, spi0/spi, gpu/vc4.
117 - some nodes doesn't have an explicit status = "okay" since they're not
118 disabled in the base file: watchdog and random.
119 - gpiomem doesn't need an explicit status = "okay".
120 - bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
121 it's now set directly in that file.
122 - bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
123 - Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

133 BCM270X_DT: Add a .dtbo target, use for overlays
134
135 Change the filenames and extensions to keep the pre-DDT style of
136 overlay (<name>-overlay.dtb) distinct from new ones that use a
137 different style of local fixups (<name>.dtbo), and to match other
138 platforms.
139
140 The RPi firmware uses the DDTK trailer atom to choose which type of
141 overlay to use for each kernel.

145 BCM270X_DT: Don't generate "linux,phandle" props
146
147 The EPAPR standard says to use "phandle" properties to store phandles,
148 rather than the deprecated "linux,phandle" version. By default, dtc
149 generates both, but adding "-H epapr" causes it to only generate
150 "phandle"s, saving some space and clutter.

157
158 BCM270X_DT: Add midi-uart0 overlay
159
160 MIDI requires 31.25kbaud, a baudrate unsupported by Linux. The
161 midi-uart0 overlay configures uart0 (ttyAMA0) to use a fake clock
162 so that requesting 38.4kbaud actually gets 31.25kbaud.

166 BCM270X_DT: Add i2c-sensor overlay
167
168 The i2c-sensor overlay is a container for various pressure and
169 temperature sensors, currently bmp085 and bmp280. The standalone
170 bmp085_i2c-sensor overlay is now deprecated.

174 BCM270X_DT: overlays/*-overlay.dtb -> overlays/*.dtbo (#1752)

176 We now create overlays as .dtbo files.
177
178 build: support for .dtbo files for dtb overlays
179
180 Kernel 4.4.6+ on RaspberryPi support .dtbo files for overlays, instead of .dtb.
181 Patch the kernel, which has faulty rules to generate .dtbo the way yocto does

2080 +Introduction
2081 +============
2082 +
2083 +This directory contains Device Tree overlays. Device Tree makes it possible
2084 +to support many hardware configurations with a single kernel and without the
2085 +need to explicitly load or blacklist kernel modules. Note that this isn't a
2086 +"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
2087 +are still configured by the board support code, but the intention is to
2088 +eventually reach that goal.
2089 +
2090 +On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
2091 +default, the Raspberry Pi kernel boots with device tree enabled. You can
2092 +completely disable DT usage (for now) by adding:
2093 +
2094 + device_tree=
2095 +
2096 +to your config.txt, which should cause your Pi to revert to the old way of
2097 +doing things after a reboot.
2098 +
2099 +In /boot you will find a .dtb for each base platform. This describes the
2100 +hardware that is part of the Raspberry Pi board. The loader (start.elf and its
2101 +siblings) selects the .dtb file appropriate for the platform by name, and reads
2102 +it into memory. At this point, all of the optional interfaces (i2c, i2s, spi)
2103 +are disabled, but they can be enabled using Device Tree parameters:
2104 +
2105 + dtparam=i2c=on,i2s=on,spi=on
2106 +
2107 +However, this shouldn't be necessary in many use cases because loading an
2108 +overlay that requires one of those interfaces will cause it to be enabled
2109 +automatically, and it is advisable to only enable interfaces if they are
2110 +needed.
2111 +
2112 +Configuring additional, optional hardware is done using Device Tree overlays
2113 +(see below).
2114 +
2115 +GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and
2116 +not the physical pin numbers.
2117 +
2118 +raspi-config
2119 +============
2120 +
2121 +The Advanced Options section of the raspi-config utility can enable and disable
2122 +Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it
2123 +is possible to both enable an interface and blacklist the driver, if for some
2124 +reason you should want to defer the loading.
2125 +
2126 +Modules
2127 +=======
2128 +
2129 +As well as describing the hardware, Device Tree also gives enough information
2130 +to allow suitable driver modules to be located and loaded, with the corollary
2131 +that unneeded modules are not loaded. As a result it should be possible to
2132 +remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can
2133 +have its contents deleted (or commented out).
2134 +
2135 +Using Overlays
2136 +==============
2137 +
2138 +Overlays are loaded using the "dtoverlay" directive. As an example, consider
2139 +the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
2140 +pre-DT world this would be loaded from /etc/modules, with an explicit
2141 +"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
2142 +this becomes a line in config.txt:
2143 +
2144 + dtoverlay=lirc-rpi
2145 +
2146 +This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
2147 +default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
2148 +DT parameters:
2149 +
2150 + dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
2151 +
2152 +Parameters always have default values, although in some cases (e.g. "w1-gpio")
2153 +it is necessary to provided multiple overlays in order to get the desired
2154 +behaviour. See the list of overlays below for a description of the parameters
2155 +and their defaults.
2156 +
2157 +The Overlay and Parameter Reference
2158 +===================================

2161 +simple to parse programmatically. NO HARD TABS.

2212 + watchdog Set to "on" to enable the hardware watchdog
2213 + (default "off")
2214 +
2215 + act_led_trigger Choose which activity the LED tracks.

2217 + (default "mmc")
2218 +
2219 + act_led_activelow Set to "on" to invert the sense of the LED
2220 + (default "off")
2221 + N.B. For Pi3 see pi3-act-led overlay.
2222 +
2223 + act_led_gpio Set which GPIO to use for the activity LED
2224 + (in case you want to connect it to an external
2225 + device)
2226 + (default "16" on a non-Plus board, "47" on a

2232 + pwr_led_gpio
2233 + As for act_led_*, but using the PWR LED.
2234 + Not available on Model A/B boards.
2235 +
2236 + N.B. It is recommended to only enable those interfaces that are needed.
2237 + Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
2238 + interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
2239 + Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
2240 + interfaces i2c0 and i2c1. Use of the numeric variants is still possible
2241 + but deprecated because the ARM/VC assignments differ between board
2242 + revisions. The same board-specific mapping applies to i2c_baudrate,
2243 + and the other i2c baudrate parameters.

4323 + * (left/right) and the other provides a subwoofer output, using DSP on the
4324 + * chip for digital high/low pass crossover.
4325 + * The initial support for this hardware, that doesn't require any codec driver
4326 + * modifications, uses only one DAC chip for stereo (left/right) output, the
4327 + * chip with 0x4c slave address. The other chip at 0x4d is currently ignored!
