2019-06-22ARM: bcm283x: Enable DMA support for SPI controllerLukas Wunner
Without this, the driver for the BCM2835 SPI controller uses interrupt mode instead of DMA mode, incurring a significant performance penalty. The Foundation's device tree has had these attributes for years, but for some reason they were never upstreamed.

2019-06-20ARM: dts: meson: switch to the generic Ethernet PHY reset bindingsMartin Blumenstingl
The snps,reset-gpio bindings are deprecated in favour of the generic "Ethernet PHY reset" bindings. Replace snps,reset-gpio from the &ethmac node with reset-gpios in the ethernet-phy node. The old snps,reset-active-low property is now encoded directly as GPIO flag inside the reset-gpios property. snps,reset-delays-us is converted to reset-assert-us and reset-deassert-us. reset-assert-us is the second cell from snps,reset-delays-us while reset-deassert-us was the third cell. Instead of blindly copying the old values (which seems strange since they gave the PHY one second to come out of reset) over this also updates the delays based on the datasheets: - RTL8211F PHY on the Odroid-C1 and MXIII-Plus needs a 10ms assert delay (the datasheet mentions: "For a complete PHY reset, this pin must be asserted low for at least 10ms") and a 30ms deassert delay (the datasheet mentions: "Wait for a further 30ms (for internal circuits settling time) before accessing the PHY register"). The old settings used 10ms for assert and 1000ms for deassert. - IP101GR PHY on the EC-100 and MXQ needs a 10ms assert delay (the datasheet mentions: "Trst | Reset period | 10ms") and a 10ms deassert delay as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock output ready after reset released | 10ms")). The old settings used 10ms for assert and 1000ms for deassert. No functional changes intended.

2019-06-20arm64: tegra: Fix Jetson Nano GPU regulatorJon Hunter
There are a few issues with the GPU regulator defined for Jetson Nano which are: 1. The GPU regulator is a PWM based regulator and not a fixed voltage regulator. 2. The output voltages for the GPU regulator are not correct. 3. The regulator enable ramp delay is too short for the regulator and needs to be increased. 2ms should be sufficient. 4. This is the same regulator used on Jetson TX1 and so make the ramp delay and settling time the same as Jetson TX1.

The reset line of the RTL8211F PHY is routed to the GPIOZ_15 pad. Describe this in the device tree so the PHY framework can bring the PHY into a known state when initializing it. GPIOZ_15 doesn't support driving the output HIGH (to take the PHY out of reset, only output LOW to reset the PHY is supported). The datasheet states it's an "3.3V input tolerant open drain (OD) output pin". Instead there's a pull-up resistor on the board to take the PHY out of reset. The GPIO itself will be set to INPUT mode to take the PHY out of reset and LOW to reset the PHY, which is achieved with the flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN).

Instead of blindly copying the old values (which seems strange since they gave the PHY one second to come out of reset) over this also updates the delays based on the datasheets: - the Realtek RTL8211F PHY needs a 10ms assert delay (the datasheet mentions: "For a complete PHY reset, this pin must be asserted low for at least 10ms") and a 30ms deassert delay (the datasheet mentions: "Wait for a further 30ms (for internal circuits settling time) before accessing the PHY register". This applies to the following boards: GXBB NanoPi K2, GXBB Odroid-C2, GXBB Vega S95 variants, GXBB Wetek variants, GXL P230, GXM Khadas VIM2, GXM Nexbox A1, GXM Q200, GXM RBox Pro boards. - the ICPlus IP101GR PHY needs a 10ms assert delay (the datasheet mentions: "Trst | Reset period | 10ms") and a deassert delay of 10ms as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock output ready after reset released | 10ms"). This applies to the GXBB Nexbox A95X board. - the Micrel KSZ9031 seems to require a 100us delay but use the same (seemingly safe) values from RTL8211F due to lack of a board to verify this. This applies to the GXBB P200 board. The GXBB P201 board is left out from this conversion because it doesn't have a dedicated PHY node (because it's not clear which PHY is used on that board).

2019-06-19arm64: dts: meson: g12a: x96-max: fix the Ethernet PHY reset lineMartin Blumenstingl
The Odroid-N2 schematics show that the following pins are used for the reset and interrupt lines: - GPIOZ_14 is the PHY interrupt line - GPIOZ_15 is the PHY reset line The GPIOZ_14 and GPIOZ_15 pins are special. The datasheet describes that they are "3.3V input tolerant open drain (OD) output pins". This means the GPIO controller can drive the output LOW to reset the PHY. To release the reset it can only switch the pin to input mode. The output cannot be driven HIGH for these pins. This requires configuring the reset line as GPIO_OPEN_DRAIN because otherwise the PHY will be stuck in "reset" state (because driving the pin HIGH seems to result in the same signal as driving it LOW). The reset line works together with a pull-up resistor (R143 in the Odroid-N2 schematics). The SoC can drive GPIOZ_14 LOW to assert the PHY reset. However, since the SoC can't drive the pin HIGH (to release the reset) we switch the mode to INPUT and let the pull-up resistor take care of driving the reset line HIGH. Switch to GPIOZ_15 for the PHY reset line instead of using GPIOZ_14 (which actually is the interrupt line). Move from the "snps" specific resets to the MDIO framework's reset-gpios because only the latter honors the GPIO flags. Use the GPIO flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN) to match with the pull-up resistor because this will: - drive the output LOW to reset the PHY (= active low) - switch the pin to INPUT mode so the pull-up will take the PHY out of reset Fixes: 51d116557b2044 ("arm64: dts: meson-g12a-x96-max: Add Gigabit Ethernet Support") Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
