x86: i8042: Correctly initialize the controller

2015-08-26T14:54:16+00:00

The existing i8042 keyboard controller driver has some issues.
First of all, it does not issue a self-test command (0xaa) to the
controller at the very beginning. Without this, the controller
does not respond to any command at all. Secondly, it initializes
the configuration byte register to turn on the keyboard's interrupt,
as U-Boot does not normally allow interrupts to be processed.
Finally, at the end of the initialization routine, it wrongly
sets the controller to disable all interfaces including both
keyboard and mouse.

of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05+00:00

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

input: twl4030: Keypad scan and input

2015-08-13T00:47:36+00:00

This allows scanning the twl4030 keypad, storing the result in a 64-byte long
matrix with the twl4030_keypad_scan function.

Detecting a key at a given column and row is made easier with the
twl4030_keypad_key function.

This adds support for detecting a few inputs exported by the TWL4030.
Currently-supported inputs are the power button, USB and charger presence.

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.
