      arm64: Update default configuration · 10a7b37b
      Thierry Reding authored 
      Enable a couple of drivers that are used on Jetson TX1:

  * GPIO_PCA953X, GPIO_PCA953X_IRQ: Two instances of this I2C GPIO
    expander are used on Jetson TX1 to expand the number of usable GPIOs
    on the I/O board. Enable the driver for this expander along with IRQ
    support.

  * MFD_MAX77620, REGULATOR_MAX77620, PINCTRL_MAX77620, GPIO_MAX77620,
    RTC_DRV_MAX77686: Enable support for the PMIC and various of its
    components found on the Jetson TX1 processor module (p2180).

  * RTC_DRV_TEGRA: This RTC is usually not hooked up to a battery on
    boards, but it can be useful as a wakeup source from suspend to RAM.

  * REGULATOR_PWM: The GPU is supplied by a regulator controlled via one
    of the Tegra's PWM channels.

  * DRM, DRM_NOUVEAU, DRM_TEGRA, DRM_PANEL_SIMPLE: Enable support for an
    optional DSI panel on Jetson TX1 as well as the GPU.

  * BACKLIGHT_GENERIC, BACKLIGHT_LP855X: The backlight on Jetson TX1, if
    shipped with a display module, is driver by an LP8557.

  * PHY_TEGRA_XUSB, USB_XHCI_TEGRA: Enable support for XUSB (USB 3.0) on
    Jetson TX1.

  * PWM, PWM_TEGRA: One of the PWM channels is used to control the
    voltage supplied to the GPU.

  * NFS_V4_1, NFS_V4_2: Support these newer versions of the NFS protocol
    to increase compatibility with distributions.

  * MFD_CROS_EC, MFD_CROS_EC_I2C and I2C_CROS_EC_TUNNEL: Used to enable
    the ChromeOS Embedded Controller and the I2C tunnel that allows the
    EC to function as an I2C bridge.

  * BATTERY_BQ27XXX: Support the battery charger and monitor found on
    the Google Pixel C.

      arm64: defconfig: Enable more IP blocks for Exynos7 and Exynos5433 · 426f754b
      Krzysztof Kozlowski authored 
      Enable more drivers for IP blocks for existing Exynos7 and upcoming
Exynos5433:
1. SPI,
2. Watchdog,
3. USB: DWC3, Exynos EHCI and OHCI,
4. Exynos ADC,
5. Samsung PWM.

These are already used by Exynos7 Espresso board or will be used by
Exynos5433 based board.

      arm64: Kconfig: select PM{,_GENERIC_DOMAINS} for ARCH_VEXPRESS · 8da7cc08
      Sudeep Holla authored 
      The Linux AMBA bus framework probes the peripheral IDs when adding the
AMBA devices very early on the boot. Generally they are on APB bus and
just require APB clocks to be on even when most of the core logic of the
IP is powered down.

However on Juno, the entire debugsys domain needs to be ON to access
even the coresight components' CID/PID registers and hence broken by
design. Accessing those while debugsys power domain is off will lead to
the bridge stalling the transactions instead of returning the slave error.

Further, the AMBA framework can't deal with !CONFIG_PM_GENERIC_DOMAINS
case: it ignores the error and proceeds to access the device region.
It was suggested to always enable CONFIG_PM{,_GENERIC_DOMAINS} in order
to handle above explained scenario.

      hpfs: implement the show_options method · 037369b8
      Mikulas Patocka authored 
      The HPFS filesystem used generic_show_options to produce string that is
displayed in /proc/mounts.  However, there is a problem that the options
may disappear after remount.  If we mount the filesystem with option1
and then remount it with option2, /proc/mounts should show both option1
and option2, however it only shows option2 because the whole option
string is replaced with replace_mount_options in hpfs_remount_fs.

To fix this bug, implement the hpfs_show_options function that prints
options that are currently selected.

      affs: fix remount failure when there are no options changed · 01d6e087
      Mikulas Patocka authored 
      Commit c8f33d0b ("affs: kstrdup() memory handling") checks if the
kstrdup function returns NULL due to out-of-memory condition.

However, if we are remounting a filesystem with no change to
filesystem-specific options, the parameter data is NULL.  In this case,
kstrdup returns NULL (because it was passed NULL parameter), although no
out of memory condition exists.  The mount syscall then fails with
ENOMEM.

This patch fixes the bug.  We fail with ENOMEM only if data is non-NULL.

The patch also changes the call to replace_mount_options - if we didn't
pass any filesystem-specific options, we don't call
replace_mount_options (thus we don't erase existing reported options).

Fixes: c8f33d0b ("affs: kstrdup() memory handling")
