phy: usb: Leave some clocks running during suspend

2022-02-23T11:06:05+00:00

[ Upstream commit 42fed57046fc74586d7058bd51a1c10ac9c690cb ]

The PHY client driver does a phy_exit() call on suspend or rmmod and
the PHY driver needs to know the difference because some clocks need
to be kept running for suspend but can be shutdown on unbind/rmmod
(or if there are no PHY clients at all).

The fix is to use a PM notifier so the driver can tell if a PHY
client is calling exit() because of a system suspend or a driver
unbind/rmmod.

phy: broadcom: Kconfig: Fix PHY_BRCM_USB config option

2022-02-16T11:58:27+00:00

[ Upstream commit 5070ce86246a8a4ebacd0c15b121e6b6325bc167 ]

The previous commit 4b402fa8e0b7 ("phy: phy-brcm-usb: support PHY on
the BCM4908") added a second "default" line for ARCH_BCM_4908 above
the original "default" line for ARCH_BRCMSTB. When two "default"
lines are used, only the first is used and this change stopped
the PHY_BRCM_USB option for being enabled for ARCH_BRCMSTB.
The fix is to use one "default line with "||".

Merge tag 'char-misc-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2021-11-04T15:21:47+00:00

Pull char/misc driver updates from Greg KH:
 "Here is the big set of char and misc and other tiny driver subsystem
  updates for 5.16-rc1.

  Loads of things in here, all of which have been in linux-next for a
  while with no reported problems (except for one called out below.)

  Included are:

   - habanana labs driver updates, including dma_buf usage, reviewed and
     acked by the dma_buf maintainers

   - iio driver update (going through this tree not staging as they
     really do not belong going through that tree anymore)

   - counter driver updates

   - hwmon driver updates that the counter drivers needed, acked by the
     hwmon maintainer

   - xillybus driver updates

   - binder driver updates

   - extcon driver updates

   - dma_buf module namespaces added (will cause a build error in arm64
     for allmodconfig, but that change is on its way through the drm
     tree)

   - lkdtm driver updates

   - pvpanic driver updates

   - phy driver updates

   - virt acrn and nitr_enclaves driver updates

   - smaller char and misc driver updates"

There is a error message within devm_ioremap_resource

2021-05-14T12:10:37+00:00

While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not
for other symbols such as __BIG_ENDIAN that is provided directly by
the compiler.

Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.
