i2c: uniphier-f: replace debug() with dev_dbg()

2017-10-15T13:32:25Z

Use dev_dbg() functions. It will be helpful to prefix log messages with the corresponding device name when the core framework is ready. While I am here, I renamed "dev", which was actually private data, into "priv" because dev->dev looks confusing. Signed-off-by: Masahiro Yamada

i2c: muxes: pca954x: look up width from chip_desc

2017-10-11T04:17:22Z

Commit 8e6eda7cda6c ("drivers/i2c/muxes/pca954x: Add pca9547 I2C mux support") introduced a chip_desc for the pca954x devices but failed to update pca954x_ofdata_to_platdata() to be aware of it. Make pca954x_ofdata_to_platdata() lookup the chip_desc to validate the device width. Signed-off-by: Chris Packham Reviewed-by: Marek Behun

dm: gpio: Correct use of -ENODEV in drivers

2017-10-09T02:41:09Z

In U-Boot -ENODEV means that there is no device. When there is a problem with the device, drivers should return an error like -ENXIO or -EREMOTEIO. When the device tree properties cannot be read correct , they should return -EINVAL. Update various GPIO drivers to follow this rule, to help with consistency for future driver writers.

treewide: replace with error() with pr_err()

2017-10-04T15:59:44Z

U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // @@@@ -error +pr_err (...) // Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass [trini: Re-run Coccinelle] Signed-off-by: Tom Rini
