[ Upstream commit 56bc54496f5d6bc638127bfc9df3742cbf0039e7 ]

The USB extal clock reference isn't associated to a crystal, it's
associated to a programmable clock, so remove the extal reference,
add the usb2_clksel.  Since usb_extal is referenced by the versaclock,
reference it here so the usb2_clksel can get the proper clock speed
of 50MHz.

[ Upstream commit ebc666f39ff67a01e748c34d670ddf05a9e45220 ]

The RZ/G2 boards expect there to be an external clock reference for
USB2 EHCI controllers.  For the Beacon boards, this reference clock
is controlled by a programmable versaclock.  Because the RZ/G2
family has a special clock driver when using an external clock,
the third clock reference in the EHCI node needs to point to this
special clock, called usb2_clksel.

Since the usb2_clksel does not keep the usb_extal clock enabled,
the 4th clock entry for the EHCI nodes needs to reference it to
keep the clock running and make USB functional.

[ Upstream commit 3ae5950db617d1cc3eb4eb55750fa9d138529b49 ]

With -Wshadow:

    drivers/thermal/rcar_gen3_thermal.c: In function ‘rcar_gen3_thermal_probe’:
    drivers/thermal/rcar_gen3_thermal.c:310:13: warning: declaration of ‘rcar_gen3_ths_tj_1’ shadows a global declaration [-Wshadow]
      310 |  const int *rcar_gen3_ths_tj_1 = of_device_get_match_data(dev);
	  |             ^~~~~~~~~~~~~~~~~~
    drivers/thermal/rcar_gen3_thermal.c:246:18: note: shadowed declaration is here
      246 | static const int rcar_gen3_ths_tj_1 = 126;
	  |                  ^~~~~~~~~~~~~~~~~~

To add to the confusion, the local variable has a different type.

Fix the shadowing by renaming the local variable to ths_tj_1.
