[PATCH AUTOSEL 4.19 003/191] media: vsp1: Fix vsp1_regs.h license header

[Sasha Levin]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

[ Upstream commit 5eea860a6fec1e60709d19832015ee0991d3e80c ]

All source files of the vsp1 driver are licensed under the GPLv2+ except
for vsp1_regs.h which is licensed under GPLv2. This is caused by a bad
copy&paste that dates back from the initial version of the driver. Fix
it.

[PATCH AUTOSEL 4.19 004/191] media: vsp1: Fix YCbCr planar formats pitch calculation

[Sasha Levin]

From: Koji Matsuoka <koji.matsuoka.xm@renesas.com>

[ Upstream commit 9b2798d5b71c50f64c41a40f0cbcae47c3fbd067 ]

YCbCr planar formats can have different pitch values for the luma and
chroma planes. This isn't taken into account in the driver. Fix it.

Based on a BSP patch from Koji Matsuoka <koji.matsuoka.xm@renesas.com>.

[PATCH AUTOSEL 4.19 105/191] phy: renesas: rcar-gen3-usb2: fix vbus_ctrl for role sysfs

[Sasha Levin]

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

[ Upstream commit 09938ea9d136243e8d1fed6d4d7a257764f28f6d ]

This patch fixes and issue that the vbus_ctrl is disabled by
rcar_gen3_init_from_a_peri_to_a_host(), so a usb host cannot
supply the vbus.

Note that this condition will exit when the otg irq happens
even if we don't apply this patch.
