ARM: tegra: Fix Tegra30 Cardhu PCA954x reset

2018-09-09T18:04:34+00:00

commit 6e1811900b6fe6f2b4665dba6bd6ed32c6b98575 upstream.

On all versions of Tegra30 Cardhu, the reset signal to the NXP PCA9546
I2C mux is connected to the Tegra GPIO BB0. Currently, this pin on the
Tegra is not configured as a GPIO but as a special-function IO (SFIO)
that is multiplexing the pin to an I2S controller. On exiting system
suspend, I2C commands sent to the PCA9546 are failing because there is
no ACK. Although it is not possible to see exactly what is happening
to the reset during suspend, by ensuring it is configured as a GPIO
and driven high, to de-assert the reset, the failures are no longer
seen.

Please note that this GPIO is also used to drive the reset signal
going to the camera connector on the board. However, given that there
is no camera support currently for Cardhu, this should not have any
impact.

ARM: dts: am3517.dtsi: Disable reference to OMAP3 OTG controller

2018-08-24T11:26:59+00:00

[ Upstream commit 923847413f7316b5ced3491769b3fefa6c56a79a ]

The AM3517 has a different OTG controller location than the OMAP3,
which is included from omap3.dtsi.  This results in a hwmod error.
Since the AM3517 has a different OTG controller address, this patch
disabes one that is isn't available.

ARM: dts: da850: Fix interrups property for gpio

[ Upstream commit 3eb1b955cd7ed1e621ace856710006c2a8a7f231 ]

The intc #interrupt-cells is equal to 1. Currently gpio
node has 2 cells per IRQ which is wrong. Remove the additional
cell for each of the interrupts.

The touchscreen driver no longer configures the device as wakeup source by

ARM: dts: imx6sx: fix irq for pcie bridge

2018-08-15T15:42:06+00:00

commit 1bcfe0564044be578841744faea1c2f46adc8178 upstream.

Use the correct IRQ line for the MSI controller in the PCIe host
controller. Apparently a different IRQ line is used compared to other
i.MX6 variants. Without this change MSI IRQs aren't properly propagated
to the upstream interrupt controller.

ARM: dts: imx6q: Use correct SDMA script for SPI5 core

2018-07-11T14:03:47+00:00

commit df07101e1c4a29e820df02f9989a066988b160e6 upstream.

According to the reference manual the shp_2_mcu / mcu_2_shp
scripts must be used for devices connected through the SPBA.

This fixes an issue we saw with DMA transfers.
Sometimes the SPI controller RX FIFO was not empty after a DMA
transfer and the driver got stuck in the next PIO transfer when
it read one word more than expected.

commit dd4b487b32a35 ("ARM: dts: imx6: Use correct SDMA script
for SPI cores") is fixing the same issue but only for SPI1 - 4.

This reverts commit 9de3a3bfed892608dc30a6bc3fd8bdbeae5b51a5 which was
commit 79935915300c5eb88a0e94fa9148a7505c14a02a upstream.

As Ben points out:
	This depends on:

	    ASoC: sgtl5000: Allow LRCLK pad drive strength to be changed

which did not show up until 4.13, so this makes no sense to have in this
stable branch.

ARM: dts: at91: sama5d4: fix pinctrl compatible string

2018-04-24T07:32:05+00:00

commit 9a06757dcc8509c162ac00488c8c82fc98e04227 upstream.

The compatible string is incorrect. Add atmel,sama5d3-pinctrl since
it's the appropriate compatible string. Remove the
atmel,at91rm9200-pinctrl compatible string, this fallback is
useless, there are too many changes.
