2021-08-30i8042: Do not abuse CONFIG namespaceTom Rini
This driver uses the CONFIG namespace to set the chips internal CONFIG namespace related bits. However, CONFIG is reserved for the top-level Kconfig based configuration system. Use CFG as the namespace here instead to avoid pollution. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2018-12-05input: i8042: Use remove() instead of exported functionsSimon Glass
We should not have exported functions in a driver. The i8042_disable() function is used to disable the keyboard. Provide a remove() method instead, which is the standard way of disabling a device. We could potentially add a method to flush input but that does not seem necessary. Signed-off-by: Simon Glass <sjg@chromium.org>
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>

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>

2012-10-19input: i8042: Provide feature to disable keyboard before booting kernelLouis Yung-Chieh Lo
The BIOS leaves the keyboard enabled during boot time so that any keystroke would interfere kernel driver initialization. Add a way to disable the keyboard to make sure no scancode will be generated during the boot time. Note that the keyboard will be re-enabled again after the kernel driver is up. This code can be called from the board functions.

2012-10-19input: Use finer grain udelays while waitng for the i8042 keyboard buffer to ā†µGabe Black
empty On x86, the i8042 keyboard controller driver frequently waits for the keyboard input buffer to be empty to make sure the controller has had a chance to process the data it was given. The way the delay loop was structured, if the controller hadn't cleared the corresponding status bit immediately, it would wait 1ms before checking again. If the keyboard responded quickly but not instantly, the driver would still wait a full 1ms when perhaps 1us would have been sufficient. Because udelay is a busy wait anyway, this change decreases the delay between checks to 1us. Also, this change gets rid of a hardcoded 250ms delay. On Stumpy, this saves 100-150ms during boot.
