2015-04-10gpio: Extend common GPIO header, simplify function namesJulius Werner
We've had gpiolib.h which defines a few common GPIO access functions for a while, but it wasn't really complete. This patch adds the missing gpio_output() function, and also renames the unwieldy gpio_get_in_value() and gpio_set_out_value() to the much easier to handle gpio_get() and gpio_set(). The header is renamed to the simpler gpio.h while we're at it (there was never really anything "lib" about it, and it was presumably just chosen due to the IPQ806x include/ conflict problem that is now resolved). It also moves the definition of gpio_t into SoC-specific code, so that different implementations are free to encode their platform-specific GPIO parameters in those 4 bytes in the most convenient way (such as the rk3288 with a bitfield struct). Every SoC intending to use this common API should supply a <soc/gpio.h> that typedefs gpio_t to a type at most 4 bytes in length. Files accessing the API only need to include <gpio.h> which may pull in additional things (like a gpio_t creation macro) from <soc/gpio.h> on its own. For now the API is still only used on non-x86 SoCs. Whether it makes sense to expand it to x86 as well should be separately evaluated at a later point (by someone who understands those systems better). Also, Exynos retains its old, incompatible GPIO API even though it would be a prime candidate, because it's currently just not worth the effort. BUG=None TEST=Compiled on Daisy, Peach_Pit, Nyan_Blaze, Rush_Ryu, Storm and Veyron_Pinky.

2015-04-08rk3288: Change all SoC headers to <soc/headername.h> systemJulius Werner
This patch is the start of a series to change all non-x86 SoC-specific headers to be included as <soc/header.h> instead of the old <soc/vendor/chip/header.h> or "header.h". It will add an include/soc/ directory under every src/soc/vendor/chip/ and append the .../include/ part of that to the global include path. This matches the usage of <arch/header.h> for architecture-specific headers and had already been done for some headers on Tegra. It has the advantage that a source file which does not know the specific SoC used (e.g. Tegra files common for multiple chips, or a global include file) can still include SoC-specific headers and access macros/types defined there. It also makes the includes for mainboard files more readable, and reduces the chance to pull in a wrong header when copying mainboard sources to use a different-related SoC (e.g. using a Tegra124 mainboard as template for a Tegra132 one). For easier maintainability, every SoC family is modified individually. This patch starts out by changing Rk3288. Also alphabetized headers in affected files since we touch them anyway. BUG=None TEST=Whole series: compared binary images for Daisy, Nyan_Blaze, Rush_Ryu, Storm, Urara and Veyron_Pinky. Confirmed that they are byte-for-byte identical except for timestamps, hashes, and __LINE__ macro replacements. Compile-tested individual patches.
