[ Upstream commit 03d9fbc39730b3e6b2e7047dc85f0f70de8fb97d ] The Meson8m2 SoC is a variant of Meson8 with some updates from Meson8b (such as the Gigabit capable DesignWare MAC). It is mostly pin compatible with Meson8, only 10 (existing) CBUS pins get an additional function (four of these are Ethernet RXD2, RXD3, TXD2 and TXD3 which are required when the board uses an RGMII PHY).

[ Upstream commit 3cd2c313f1d618f92d1294addc6c685c17065761 ] On the CP110 components which are present on the Armada 7K/8K SoC we need to explicitly enable the clock for the registers. However it is not needed for the AP8xx component, that's why this clock is optional. With this patch both clock have now a name, but in order to be backward compatible, the name of the first clock is not used. It allows to still use this clock with a device tree using the old binding.

2018-04-13clk: meson: meson8b: add compatibles for Meson8 and Meson8m2Martin Blumenstingl
[ Upstream commit 855f06a1009faabb0c6a3e9b49d115496d325856 ] The clock controller on Meson8, Meson8b and Meson8m2 is very similar based on the code from the Amlogic GPL kernel sources. Add separate compatibles for each SoC to make sure that we can easily implement all the small differences for each SoC later on. In general the Meson8 and Meson8m2 seem to be almost identical as they even share the same mach-meson8 directory in Amlogic's GPL kernel sources. The main clocks on Meson8, Meson8b and Meson8m2 are very similar, because they are all using the same PLL values, 90% of the clock gates are the same (the actual diffstat of the mach-meson8/clock.c and mach-meson8b/clock.c files is around 30 to 40 lines, when excluding all commented out code). The difference between the Meson8 and Meson8b clock gates seem to be: - Meson8 has AIU_PCLK, HDMI_RX, VCLK2_ENCT, VCLK2_ENCL, UART3, CSI_DIG_CLKIN gates which don't seem to be available on Meson8b - the gate on Meson8 for bit 7 seems to be named "_1200XXX" instead of "PERIPHS_TOP" (on Meson8b) - Meson8b has a SANA gate which doesn't seem to exist on Meson8 (or on Meson8 the same bit is used by the UART3 gate in Amlogic's GPL kernel sources) None of these gates is added for now, since it's unclear whether these definitions are actually correct (the VCLK2_ENCT gate for example is defined, but only used in some commented block). The main difference between all three SoCs seem to be the video (VPU) clocks. Apart from different supported clock rates (according to vpu.c in mach-meson8 and mach-meson8b from Amlogic's GPL kernel sources) the most notable difference is that Meson8m2 has a GP_PLL clock and a mux (probably the same as on the Meson GX SoCs) to support glitch-free (clock rate) switching. None of these VPU clocks are not supported by our mainline meson8b clock driver yet though.

2018-04-13dt-bindings: display: sun4i: Add allwinner,tcon-channel propertyMaxime Ripard
[ Upstream commit 22662f12768f971809b478386d9cc4947d00497a ] The Allwinner Timings Controller has two, mutually exclusive, channels. When the binding has been introduced, it was assumed that there would be only a single user per channel in the system. While this is likely for the channel 0 which only connects to LCD displays, it turns out that the channel 1 can be connected to multiple controllers in the SoC (HDMI and TV encoders for example). And while the simultaneous use of HDMI and TV outputs cannot be achieved, switching from one to the other at runtime definitely sounds plausible. Add an extra property, allwinner,tcon-channel, to specify for a given endpoint which TCON channel it is connected to, while falling back to the previous mechanism if that property is missing.

2017-12-05hwmon: (jc42) optionally try to disable the SMBUS timeoutPeter Rosin
commit 68615eb01f82256c19e41967bfb3eef902f77033 upstream. With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver is not always capable of avoiding the 25-35 ms timeout as specified by the SMBUS protocol. This may cause silent corruption of the last bit of any transfer, e.g. a one is read instead of a zero if the sensor chip times out. This also affects the eeprom half of the nxp-se97 chip, where this silent corruption was originally noticed. Other I2C adapters probably suffer similar issues, e.g. bit-banging comes to mind as risky... The SMBUS register in the nxp chip is not a standard Jedec register, but it is not special to the nxp chips either, at least the atmel chips have the same mechanism. Therefore, do not special case this on the manufacturer, it is opt-in via the device property anyway.

While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW.

Since the A31s does not have MIPI DSI, it only has a mux for the HDMI controller input. This patch only adds support for the compatible strings. Actual support for the mux controls should be added with HDMI and MIPI DSI support.

2017-04-12drm/sun4i: Add compatible strings for A31/A31s display pipelinesChen-Yu Tsai
commit 49c440e87cd6f547f93d0dc53571ae0e11d9ec8f upstream. The A31's display pipeline has 2 frontends, 2 backends, and 2 TCONs. It also has new display enhancement blocks, such as the DRC (Dynamic Range Controller), the DEU (Display Enhancement Unit), and the CMU (Color Management Unit). It supports HDMI, MIPI DSI, and 2 LCD/LVDS channels. The A31s display pipeline is almost the same, just without MIPI DSI. Only the TCON seems to be different, due to the missing mux for MIPI DSI. Add compatible strings for both of them.

2016-11-28Documentation: devicetree: clarify usage of the RGMII phy-modesMartin Blumenstingl
RGMII requires special RX and/or TX delays depending on the actual hardware circuit/wiring. These delays can be added by the MAC, the PHY or the designer of the circuit (the latter means that no delay has to be added by PHY or MAC). There are 4 RGMII phy-modes used describe where a delay should be applied: - rgmii: the RX and TX delays are either added by the MAC (where the exact delay is typically configurable, and can be turned off when no extra delay is needed) or not needed at all (because the hardware wiring adds the delay already). The PHY should neither add the RX nor TX delay in this case. - rgmii-rxid: configures the PHY to enable the RX delay. The MAC should not add the RX delay in this case. - rgmii-txid: configures the PHY to enable the TX delay. The MAC should not add the TX delay in this case. - rgmii-id: combines rgmii-rxid and rgmii-txid and thus configures the PHY to enable the RX and TX delays. The MAC should neither add the RX nor TX delay in this case. Document these cases in the ethernet.txt documentation to make it clear when to use each mode. If applied incorrectly one might end up with MAC and PHY both enabling for example the TX delay, which breaks ethernet TX traffic on 1000Mbit/s links.

Except for the omap3 fix for the SoC features printed, all these are quite trivial and tiny.

The current ipmi/bt-bmc driver implements the IPMI version and we should reflect its nature in the compatible node name using 'aspeed,ast2400-ibt-bmc' instead of 'aspeed,ast2400-bt-bmc'.

2016-11-10PCI: rockchip: Add three new resets as required propertiesShawn Lin
pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software wasn't needed to control it again in theory. But it didn't work properly, so we do need to do it again and add enough delay between the assert of pm_rst and the deassert of pm_rst. The Soc intergrated with this controller, rk3399, is still under MP test internally, so the backward compatibility won't be a big deal.
