* i2c: introduce device_i2c_driver() macroMarco Felsch2018-10-191-8/+1
| | | | | | | | | Add macro and dependency to avoid boilerplate code. Since now simple i2c drivers only have to include the i2c.h header and call the device_i2c_driver() macro to register a i2c device driver.

* param: make parameter functions more consistentSascha Hauer2017-04-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* input: Add BB_ prefix to KEY_ definesSascha Hauer2014-02-171-2/+2
| | | | | | | Our KEY_ defines conflict with the standard Linux KEY_ defines, so add a BB_ prefix to them. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* console: drop f_caps and check the function pointer getc/putc insteadJean-Christophe PLAGNIOL-VILLARD2013-09-211-1/+0
| | | | | | | | | | None of the driver make the difference between STDOUT and STDERR. So we just need to check if putc or getc are filled in the console_device save 32 bytes on versatilepb Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

use irq pin as the pin is asserted untill we clear it This will allow to do not poll on i2c which slow down barebox If no irq_pin is provided fall back on i2c polling Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
