ARM: dts: at91: sama5d3_xplained: not all ADC channels are available

2017-05-25T12:30:15+00:00

commit d3df1ec06353e51fc44563d2e7e18d42811af290 upstream.

Remove ADC channels that are not available by default on the sama5d3_xplained
board (resistor not populated) in order to not create confusion.

ARM: dts: at91: sama5d3_xplained: fix ADC vref

2017-05-25T12:30:15+00:00

commit 9cdd31e5913c1f86dce7e201b086155b3f24896b upstream.

The voltage reference for the ADC is not 3V but 3.3V since it is connected to
VDDANA.

ARM: tegra: paz00: Mark panel regulator as enabled on boot

2017-05-25T12:30:07+00:00

commit 0c18927f51f4d390abdcf385bff5f995407ee732 upstream.

Current U-Boot enables the display already. Marking the regulator as
enabled on boot fixes sporadic panel initialization failures.

ARM: dts: at91: sama5d2: add dma properties to UART nodes

2017-03-30T07:35:18+00:00

commit b1708b72a0959a032cd2eebb77fa9086ea3e0c84 upstream.

The dmas/dma-names properties are added to the UART nodes. Note that additional
properties are needed to enable them at the board level: check bindings for
details.

commit ef8d02d4a2c36f7a93e74c95a9c419353b310117 upstream.

Enable DMA on usart3 to get a more reliable console. This is especially
useful for automation and kernelci were a kernel with PROVE_LOCKING enabled
is quite susceptible to character loss, resulting in tests failure.

ARM: dts: imx6qdl-nitrogen6_max: fix sgtl5000 pinctrl init

2017-01-26T07:23:49+00:00

commit 6ab5c2b662e2dcbb964099bf7f19e9dbc9ae5a41 upstream.

This patch fixes the following error:
sgtl5000 0-000a: Error reading chip id -6
imx-sgtl5000 sound: ASoC: CODEC DAI sgtl5000 not registered
imx-sgtl5000 sound: snd_soc_register_card failed (-517)

The problem was that the pinctrl group was linked to the sound driver
instead of the codec node. Since the codec is probed first, the sys_mclk
was missing and it would therefore fail to initialize.

ARM: dts: da850-evm: fix read access to SPI flash

2017-01-26T07:23:49+00:00

commit 43849785e1079f6606a31cb7fda92d1200849728 upstream.

Read access to the SPI flash are broken on da850-evm, i.e. the data
read is not what is actually programmed on the flash.
According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not
usable anymore and only the FAST_READ command can be used to read data.

This commit specifies in the DTS that we should use FAST_READ command
instead of the READ command.

ARM: dts: imx31: fix AVIC base address

commit af92305e567b7f4c9cf48b9e46c1f48ec9ffb1fb upstream.

On i.MX31 AVIC interrupt controller base address is at 0x68000000.

The problem was shadowed by the AVIC driver, which takes the correct
base address from a SoC specific header file.
