+
+I had made last-minute changes before submitting the patch "sh-pfc: r8a7791:
+add CAN pin groups"; now I'm seeing that they weren't complete: I had missed
+update to the pin group names in pin[01]_groups[]. Drop the "_a" suffixes there.

+Subject: [PATCH] can: rcar_can: support all input clocks
+
+When writing the driver, I didn't give enough attention to the possible sources
+of the CAN clock: although the value of the CLKR register was specified by the
+platform data, the driver only handled one case, that is CAN clock being
+sourced from the clkp1 clock, the same that clocks the whole CAN module. In
+order to fix that overlook, we'll have to handle the CAN clock separately from
+the peripheral clock (however, clkp1 will be specified for a CAN device only
+once)...

++Renesas R-Car CAN controller Device Tree Bindings
++-------------------------------------------------
++
++Required properties:
++- compatible: "renesas,can-r8a7778" if CAN controller is a part of R8A7778 SoC.
++ "renesas,can-r8a7779" if CAN controller is a part of R8A7779 SoC.
++ "renesas,can-r8a7790" if CAN controller is a part of R8A7790 SoC.
++ "renesas,can-r8a7791" if CAN controller is a part of R8A7791 SoC.
++- reg: physical base address and size of the R-Car CAN register map.
++- interrupts: interrupt specifier for the sole interrupt.
++- clocks: phandles and clock specifiers for 3 CAN clock inputs.
++- clock-names: 3 clock input name strings: "clkp1", "clkp2", "can_clk".
++- pinctrl-0: pin control group to be used for this controller.
++- pinctrl-names: must be "default".
++
++Optional properties:
++- renesas,can-clock-select: R-Car CAN Clock Source Select. Valid values are:
++ <0x0> (default) : Peripheral clock (clkp1)
++ <0x1> : Peripheral clock (clkp2)
++ <0x3> : Externally input clock
++
++Example
++-------
++
++SoC common .dtsi file:
++
++ can0: can@e6e80000 {
++ compatible = "renesas,can-r8a7791";
++ reg = <0 0xe6e80000 0 0x1000>;
++ interrupts = <0 186 IRQ_TYPE_LEVEL_HIGH>;
++ clocks = <&mstp9_clks R8A7791_CLK_RCAN0>,
++ <&cpg_clocks R8A7791_CLK_RCAN>, <&can_clk>;
++ clock-names = "clkp1", "clkp2", "can_clk";
++ status = "disabled";
++ };
++
++Board specific .dts file:
++

+Subject: [PATCH] ARM: shmobile: silk: Remove I2C1 clock from clk_enables
+ array
+
+Remove I2C1 clock from clk_enables array since it is not needed.
+I2C clocks are handled by the OF driver while shmobile_clk_workaround
+is only needed for platform devices.
