2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-06-01cros_ec: Update the cros_ec keyboard driver to livetreeSimon Glass
Update this driver and key_matrix to support a live device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2015-11-19input: Support the German keymapSimon Glass
Add support for the German keymap, taken from i8042.c. This can be selected when the input library it initialised. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-11-19dm: cros_ec: Convert cros_ec keyboard driver to driver modelSimon Glass
Adjust the cros_ec keyboard driver to support driver model. Make this the default for all Exynos boards so that those that use a keyboard will build correctly with this driver. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-11-19cros_ec: Use udevice instead of cros_ec_dev for keyboard functionsSimon Glass
In preparation for converting the cros_ec keyboard driver to driver model, adjust the cros_ec functions it will use to use a normal struct udevice. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-11-19input: Add the keycode translation tables separatelySimon Glass
Require the caller to add the keycode translation tables separately so that it can select which ones to use. In a later patch we will add the option to add German tables. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

DEV_FLAGS_SYSTEM does not have any actual meaning, hence drop it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
2015-04-18cros_ec: exynos: Match up device tree with kernel versionSimon Glass
The U-Boot device trees are slightly different in a few places. Adjust them to remove most of the differences. Note that U-Boot does not support the concept of interrupts as distinct from GPIOs, so this difference remains. For sandbox, use the same keyboard file as for ARM boards and drop the host emulation bus which seems redundant. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-01-05cros-ec-keyboard: Synchronize DT binding from linuxSjoerd Simons
The ChromeOS EC keyboard is used by various different chromebooks. Peach pi being the third board in the u-boot tree to use it (snow and peach pit the other two). Rather then embedding the same big DT node in the peach-pi DT again, copy the dtsi snippit & bindings documentation from linux and include it in all 3 boards. This slightly changes the dt bindings in u-boot: * google,key-rows becomes keypad,num-rows * google,key-colums becomes keypad,num-colums * google,repeat-delay-ms and google,repeat-rate-ms are no longer used and replaced by hardcoded values (similar to tegra kbc) Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
2014-03-17cros_ec: Support systems with no EC interruptSimon Glass
Some systems do not have an EC interrupt. Rather than assuming that the interrupt is always present, and hanging forever waiting for more input, handle the missing interrupt. This works by reading key scans only until we get an identical one. This means the EC keyscan FIFO is empty.
