[PATCH v2 00/14] at91 fixes and enhancements

[Claudiu Beznea]

Hi,

This series contains fixes and enhancements for Atmel/Microchip boards,
mainly for SoM1-EK board, SAMA5D2 Xplained board and SAM9x5 boards.
Please accept them for 4.15.

Thank you,
Claudiu Beznea

Changes since v1:
- correct author for some patches; these were developed first on internal
branch and then were manualy ported by me to Linux public tree (since the device
tree files are different) but then I forgot to keep the real author
- removed patch "ARM: dts: at91: sama5d2_xplained: Add charger node of pmic."
from this series since it was already applied on at91-dt branch (see [1])

serial lines and ttyS2 for the mikro BUS 2 serial lines.

[PATCH v2 08/14] ARM: dts: at91: sama5d27_som1_ek: remove pull-up on SD/MMC lines

[Claudiu Beznea]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

As the board have the proper pull-ups soldered on the data
and CMD lines we don't need them specified in the PADs. So remove
the "bias-pull-up" property and set "bias-disable".

Add the PWM0 interface and one output of channel 0 (on PC10) on this headless

particular board of the series (ISI is enabled on at91sam9g25ek, as an example
but we can do the other way around).

[PATCH v2 13/14] ARM: dts: at91: at91sam9x25ek: add pwm0

[Claudiu Beznea]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

Add the PWM0 interface and one output of channel 0 (on PC10) on this headless
board. The output conflicts with LCD and ISI, so only enable it for this
particular board of the series (ISI is enabled on at91sam9g25ek, as an example
but we can do the other way around).

[PATCH v2 14/14] ARM: dts: at91: at91sam9x5ek: use DMA for USART0

[Claudiu Beznea]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

Use DMA for USART0 (which is used as ttyS1) as we have enough channels and to
show how to specify DMA use with serial nodes.
