Input: imx_keypad - check for clk_prepare_enable() error

2015-06-22T16:33:51Z

clk_prepare_enable() may fail, so we should better check its return value and propagate it in the case of error. Signed-off-by: Fabio Estevam Signed-off-by: Dmitry Torokhov

Input: improve usage of gpiod API

2015-06-17T00:09:14Z

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Simplify drivers accordingly. Note that in the case of the drv260x driver error checking is more strict now because -ENOSYS is reported to the caller now. But this should only be returned if GPIOLIB is disabled which shouldn't happen as the driver depends on GPIOLIB.

mfd: cros_ec: Support multiple EC in a system

2015-06-15T12:18:23Z

Chromebooks can have more than one Embedded Controller so the cros_ec device id has to be incremented for each EC registered. Add a new structure to represent multiple EC as different char devices (e.g: /dev/cros_ec, /dev/cros_pd). It connects to cros_ec_device and allows sysfs inferface for cros_pd. Also reduce number of allocated objects, make chromeos sysfs class object a static and add refcounting to prevent object deletion while command is in progress.

mfd: cros_ec: Move protocol helpers out of the MFD driver

2015-06-15T12:18:20Z

The MFD driver should only have the logic to instantiate its child devices and setup any shared resources that will be used by the subdevices drivers. The cros_ec MFD is more complex than expected since it also has helpers to communicate with the EC. So the driver will only get more bigger as other protocols are supported in the future. So move the communication protocol helpers to its own driver as drivers/platform/chrome/cros_ec_proto.c.

mfd: cros_ec: Use a zero-length array for command data

2015-06-15T12:18:19Z

Commit 1b84f2a4cd4a ("mfd: cros_ec: Use fixed size arrays to transfer data with the EC") modified the struct cros_ec_command fields to not use pointers for the input and output buffers and use fixed length arrays instead. This change was made because the cros_ec ioctl API uses that struct cros_ec_command to allow user-space to send commands to the EC and to get data from the EC. So using pointers made the API not 64-bit safe. Unfortunately this approach was not flexible enough for all the use-cases since there may be a need to send larger commands on newer versions of the EC command protocol. So to avoid to choose a constant length that it may be too big for most commands and thus wasting memory and CPU cycles on copy from and to user-space or having a size that is too small for some big commands, use a zero-length array that is both 64-bit safe and flexible. The same buffer is used for both output and input data so the maximum of these values should be used to allocate it.

Input: max7359_keypad - do not set MAX7359_CFG_INTERRUPT flag

2015-05-15T22:58:39Z

In datasheet of max7359 there is the following description of this flag: 0 - INT cleared when FIFO empty, 1 - INT cleared after host read. In this mode, I2C should read FIFO until interrupt condition removed, or further INT may be lost. So, if we set this flag, we have to read FIFO until it becomes empty. But in interrupt we read FIFO just once. This lead to "keyboard" hang until reboot, if we press several keys, because of interrupt handler read just one "press" from FIFO and clear interrupt.
