2016-10-04rockchip: Remove pulls for gpio_output(), clean up codeJulius Werner
Output GPIOs should never have a pull-up or pull-down resistor attached since they're actively driven. Since some GPIOs get initialized with a pull at power-on reset, we should explicitly overwrite that setting. Most other platforms do this on gpio_output, but Rockchip hadn't yet. Also, shuffle some code around to make things cleaner and allow for easier code reuse. BRANCH=None BUG=chrome-os-partner:52526 TEST=Booted Kevin.

2016-07-12rockchip/rk3399: Fix pinctrl pull bias settingsShunqian Zheng
The pull bias settings for GPIO0_A, GPIO0_B, GPIO2_C and GPIO2_D are different from the other GPIO banks. This patch adds a callback function to get the GPIO pull value of each SoC(rk3288 and rk3399) so we can still use the common GPIO driver.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

This patch is a manual cleanup of all the rubble left by coccinelle waltzing through our code base.

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.
