2018-05-30ARM: dts: porter: Fix HDMI output routingLaurent Pinchart
[ Upstream commit d4b78db6ac3e084e2bdc57d5518bd247c727f396 ] The HDMI encoder is connected to the RGB output of the DU, which is port@0, not port@1. Fix the incorrect DT description.

2017-03-13ARM: dts: porter: Drop superfluous status update for frequency overrideGeert Uytterhoeven
The pcie_bus_clk device node is already enabled in r8a7791.dtsi, so there is no need to update its status again. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2016-04-20ARM: dts: r8a7791: Don't disable referenced optional clocksSjoerd Simons
clk_get on a disabled clock node will return EPROBE_DEFER, which can cause drivers to be deferred forever if such clocks are referenced in their clocks property. Update the various disabled external clock nodes to default to a frequency of 0, but don't disable them to prevent this.

2016-03-28ARM: dts: porter: Remove unnecessary clock-output-names propertiesSimon Horman
* Fixed rate and fixed factor clocks do not require an clock-output-names property. * Since 07705583e920fef6 ("clk: shmobile: div6: Make clock-output-names optional") Renesas div6 clocks do not require a clock-output-names property. In the above cases there is only one clock output and its name is taken from that of the clock node. Accordingly, remove the unnecessary clock-output-names properties and as necessary update the node names.

2016-03-02ARM: dts: porter: remove enable prop from HS-USB device nodeSergei Shtylyov
In the final versions of the Porter board (called "PORTER_C") Renesas decided to get rid of the Maxim Integrated MAX3355 OTG chip and didn't add any other provision to differ the host/gadget mode, so we'll have to remove no longer valid "renesas,enable-gpio" property from the HS-USB device node. Hopefully, the earlier revisions of the board were never seen in the wild...
