ns16550: Fix mem mapped endian check

2018-02-23T15:40:50Z

Do a explicit check for CONFIG_SYS_BIG_ENDIAN and CONFIG_SYS_LITTLE_ENDIAN to avoid errors on platforms where both are undefined (x86). Signed-off-by: Bernhard Messerklinger Reviewed-by: Hannes Schmelzer

serial: Replace CONFIG_ with CONFIG_IS_ENABLED

2018-02-16T15:43:10Z

Cosmetic change, replace CONFIG_* with CONFIG_IS_ENABLED(*) . Signed-off-by: Marek Vasut Cc: Nobuhiro Iwamatsu

serial: Make full device search optional

2018-01-29T13:18:02Z

Commit 608b0c4ad4e5ec0c ("serial: Use next serial device if probing fails") added code to search for more serial devices if the default one was not probed correctly. Unfortunately, that breaks omap3_evm. So while investigating why that is the case, let's disable the full search for everyone but bcm283x where it is needed.

bcm2835_pl011_serial: Add BCM2835 specific serial driver

2018-01-28T17:27:36Z

On bcm2835 we need to ensure we only access serial devices that are muxed to the serial output pins of the pin header. To achieve this for the pl011 device, add a bcm2835 specific pl011 wrapper device that does this check but otherwise behaves like a pl011 device. Signed-off-by: Alexander Graf

bcm2835_mu_serial: Convert to Kconfig

2018-01-28T17:27:36Z

Setting config options using headers is deprecated. This patch converts the BCM2835 Mini-UART to Kconfig. Signed-off-by: Alexander Graf

pl01x: Convert CONFIG_PL01X_SERIAL to Kconfig

2018-01-28T17:27:35Z

We want to use Kconfig logic to depend on whether pl01x devices are built in, so let's convert their inclusion selection to Kconfig. This round goes to pl01x. Signed-off-by: Alexander Graf

pl011: Convert CONFIG_PL011_SERIAL to Kconfig

2018-01-28T17:27:35Z

We want to use Kconfig logic to depend on whether pl01x devices are built in, so let's convert their inclusion selection to Kconfig. This round goes to pl011. Signed-off-by: Alexander Graf

pl010: Convert CONFIG_PL010_SERIAL to Kconfig

2018-01-28T17:27:35Z

We want to use Kconfig logic to depend on whether pl01x devices are built in, so let's convert their inclusion selection to Kconfig. This round goes to pl010. Signed-off-by: Alexander Graf

pl01x: Convert to dev_read

2018-01-28T17:27:34Z

The fdtdec API is deprecated, convert the pl010 and pl011 devices to use the dev_read API instead. Signed-off-by: Alexander Graf

serial_bcm283x_mu: Fail loading if not muxed

2018-01-28T17:27:34Z

The bcm283x mini-uart is only really usable as U-Boot serial output when it is muxed to the UART pins of the RPi pin header. So fail probing in case it is not muxed correctly, as in that case firmware did not initialize it properly either. Signed-off-by: Alexander Graf
