2018-02-22arm: spear13xx: Fix dmas cellsViresh Kumar
commit cdd10409914184c7eee5ae3e11beb890c9c16c61 upstream. The "dmas" cells for the designware DMA controller need to have only 3 properties apart from the phandle: request line, src master and destination master. But the commit 6e8887f60f60 updated it incorrectly while moving from platform code to DT. Fix it.

2018-02-22ARM: dts: nomadik: add interrupt-parent for clcdArnd Bergmann
commit e8bfa0422469cdfc86be3f525f621b1d44d2481b upstream. The clcd device is lacking an interrupt-parent property, which makes the interrupt unusable and shows up as a warning with the latest dtc version: arch/arm/boot/dts/ste-nomadik-s8815.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000 arch/arm/boot/dts/ste-nomadik-nhk15.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000 I looked up the old board files and found that this interrupt has the same irqchip as all the other on-chip device, it just needs one extra line.

2018-02-22ARM: lpc3250: fix uda1380 gpio numbersArnd Bergmann
commit ca32e0c4bf9ca4b87089c5a5ce945e5f2ec890da upstream. dtc warns about obviously incorrect GPIO numbers for the audio codec on both lpc32xx boards: arch/arm/boot/dts/lpc3250-phy3250.dtb: Warning (gpios_property): reset-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c@400A0000/uda1380@18 arch/arm/boot/dts/lpc3250-phy3250.dtb: Warning (gpios_property): power-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c@400A0000/uda1380@18 arch/arm/boot/dts/lpc3250-ea3250.dtb: Warning (gpios_property): reset-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c@400A0000/uda1380@18 arch/arm/boot/dts/lpc3250-ea3250.dtb: Warning (gpios_property): power-gpio property size (12) too small for cell size 3 in /ahb/apb/i2c@400A0000/uda1380@18 It looks like the nodes are written for a different binding that combines the GPIO number into a single number rather than a bank/number pair. I found the right numbers on stackexchange.com, so this patch fixes the warning and has a reasonable chance of getting things to actually work.

2018-01-23ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7Thomas Petazzoni
commit 56aeb07c914a616ab84357d34f8414a69b140cdf upstream. MPP7 is currently muxed as "gpio", but this function doesn't exist for MPP7, only "gpo" is available. This causes the following error: kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7 pinctrl core: failed to register map default (6): invalid type given kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22 kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22 kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22 So the pinctrl driver is not probed, all device drivers (including the UART driver) do a -EPROBE_DEFER, and therefore the system doesn't really boot (well, it boots, but with no UART, and no devices that require pin-muxing). Back when the Device Tree file for this board was introduced, the definition was already wrong. The pinctrl driver also always described as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11, a hog pin failing to be muxed was turned from a simple warning to a hard error that caused the entire pinctrl driver probe to bail out. This is probably the result of commit 6118714275f0a ("pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()"). This commit fixes the Device Tree to use the proper "gpo" function for MPP7, which fixes the boot of OpenBlocks A7, which was broken since Linux 4.11.

2017-12-21arm: dts: imx7: disable pull-up on multiplexed pinsStefan Agner
The PWM<A> and PWM<D> have multiplexed pins which by default have a pull-up enabled. Take them into the same pinmux group as the PWM pin and disable pull-ups. This also makes sure that there is no conflicting usage of the same pin...

2017-12-21ARM: dts: imx7-colibri: Specify cable detect as ID and VBUS pinStefan Agner
Commit 95c163471135 ("usb: chipidea: use of extcon framework to work for non OTG case") requires both pins to be specified (ID and VBUS pin) to work correctly. Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2017-12-21ARM: dts: imx7: use 3 PWM cellsStefan Agner
The PWM driver has now capability to specify the PWM polarity which is e.g. for backlight control. Allow to make use of PWM polarity by specifying pwm-cells to be 3 in the base dt.
