i8042: Add keyboard enable logic in kbd_reset()

2015-04-18T17:11:16+00:00

This code appears to be missing a piece that is needed on some keyboards
to enable the keyboard. Add this in.

This makes the keyboard work correctly on chromebook_link.

cros_ec: exynos: Match up device tree with kernel version

2015-04-18T17:11:16+00:00

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.

dm: cros_ec: Convert to Kconfig

2015-02-19T13:19:18+00:00

Since both I2C and SPI are converted to Kconfig, we can convert cros_ec
to Kconfig for these buses.

LPC will need to wait until driver mode PCI is available.

cros-ec-keyboard: Synchronize DT binding from linux

2015-01-06T00:45:16+00:00

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)

kconfig: add blank Kconfig files

This would be useful to start moving various config options.

stdio: Pass device pointer to stdio methods

2014-07-23T13:07:23+00:00

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.

       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

stdio: Remove redundant code around stdio_register() calls

2014-07-23T13:07:23+00:00

There is no point in setting a structure's memory to NULL when it has
already been zeroed with memset().

Also, there is no need to create a stub function for stdio to call - if the
function is NULL it will not be called.

This is a clean-up, with no change in functionality.

cros_ec: Support systems with no EC interrupt

2014-03-18T02:05:46+00:00

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.
