| | | | | | | | | | | | | | | | | Many drivers use a common form of offset + flags for device tree nodes. e.g.: <&gpio1 2 GPIO_ACTIVE_LOW> This patch adds a common implementation of this type of parsing and calls it when a gpio driver doesn't supply its' own xlate routine. This will allow removal of the driver-specific versions in a handful of drivers and simplify the addition of new drivers.

* video: tegra: refuse to bind to disabled dcsStephen Warren2016-05-172-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents the following boot-time message on any board where only the first DC is in use, yet the DC's DT node is enabled: stdio_add_devices: Video device failed (ret=-22) (This happens on at least Harmony, Ventana, and likely any other Tegra20 board with display enabled other than Seaboard). The Tegra DC's DT node represents a display controller. It may itself drive an integrated RGB display output, or be used by some other display controller such as HDMI. For this reason the DC node itself is not enabled/disabled in DT; the DC itself is considered a shared resource, not the final (board-specific) display output. The node should instantiate a display output driver only if the rgb subnode is enabled. Other output drivers are free to use the DC if they are enabled and their DT node references the DC's DT node. Adapt the Tegra display drivers' bind() routine to only bind to the DC's DT node if the RGB subnode is enabled. Now that the display driver does the right thing, remove the workaround for this issue from Seaboard's DT file.

* dm: core: allow drivers to refuse to bindStephen Warren2016-05-171-0/+4
| | | | | | | | | | | | | In some cases, drivers may not want to bind to a device. Allow bind() to return -ENODEV in this case, and don't treat this as an error. This can be useful in situations where some information source other than the DT node's main status property indicates whether the device should be enabled, for example other DT properties might indicate this, or the driver might query non-DT sources such as system fuses or a version number register.

* buildman: allow more incremental buildingStephen Warren2016-05-175-11/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One use-case for buildman is to continually run it interactively after each small step in a large refactoring operation. This gives more immediate feedback than making a number of commits and then going back and testing them. For this to work well, buildman needs to be extremely fast. At present, a couple issues prevent it being as fast as it could be: 1) Each time buildman runs "make %_defconfig", it runs "make mrproper" first. This throws away all previous build results, requiring a from-scratch build. Optionally avoiding this would speed up the build, at the cost of potentially causing or missing some build issues. 2) A build tree is created per thread rather than per board. When a thread switches between building different boards, this often causes many files to be rebuilt due to changing config options. Using a separate build tree for each board would avoid this. This does put more strain on the system's disk cache, but it is worth it on my system at least. This commit adds two command-line options to implement the changes described above; -I ("--incremental") turns of "make mrproper" and -P ("--per-board-out-dir") creats a build directory per board rather than per thread. Tested: ./tools/buildman/buildman.py tegra ./tools/buildman/buildman.py -I -P tegra ./tools/buildman/buildman.py -b tegra_dev tegra ./tools/buildman/buildman.py -b tegra_dev -I -P tegra ... each once after deleting the buildman result/work directory, and once "incrementally" after a previous identical invocation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new driver that supports driver model for pca953x. The pca953x chips are used as I2C I/O expanders. This driver is designed to support the following chips: " 4 bits: pca9536, pca9537 8 bits: max7310, max7315, pca6107, pca9534, pca9538, pca9554, pca9556, pca9557, pca9574, tca6408, xra1202 16 bits: max7312, max7313, pca9535, pca9539, pca9555, pca9575, tca6416 24 bits: tca6424 40 bits: pca9505, pca9698 " But for now this driver only supports max 24 bits and pca953x compatible chips. pca957x compatible chips are not supported now. These can be addressed when we need to add such support for the different chips.

| | | | | | | | | | | | | | | | Commit bfb33f0bc45b ("sunxi: mctl_mem_matches: Add missing memory barrier") broke compilation for the Pine64, as dram_helper.c now includes <asm/armv7.h>, which does not compile on arm64.

Also extend the inline assembly to take the "sy" argument, which is optional for ARMv7, but mandatory for v8. This fixes compilation for 64-bit sunxi boards (Pine64).
