Merge tag 'extcon-next-for-4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon for 4.14 Detailed description for this pull request: 1. Add new 'extcon-usbc-cros-ec.c' driver - ChromeOS Embedded Controller extcon driver supports the detection of the Display Port (EXTCON_DISP_DP) through USB C-type and contol it. 2. Update extcon core - Modify the description for both functions and structures in order to improve the readability and give the more correct guide about the role of functions because there are different explanation even if the same arguments. - Keep the indentation with tab instead of space - Remove the following deprecated extcon API. The deprecated API are exchanged on all of linux tree. : extcon_get_cable_state_() -> extcon_get_state() : extcon_set_cable_state_() -> extcon_set_state_sync() 3. Include the two immutable branch as following: - ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory. - ib-extcon-usb-phy-4.14 for removing the deprecated extcon API because the usb/phy driver usese the deprecated extcon API. So, this immutable branch alters the extcon API and then remove them from extcon. 4. Fix minor issue of extcon driver - Fix the MHL detection on extcon-max77693.c - Convert to using %pOF instead of full_name on extcon.c - Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by:

Commit 3ca9b1ac ("misc: eeprom_93xx46: Add support for a GPIO 'select' line.") introduced the optional usage of 'select-gpios' by using the gpiod API in a convoluted way. Rewrite the gpiod handling to make the code simpler. Signed-off-by:

Hold on to the pages allocated and mapped for transaction buffers until the system is under memory pressure. When that happens, use linux shrinker to free pages. Without using shrinker, patch "android: binder: Move buffer out of area shared with user space" will cause a significant slow down for small transactions that fit into the first page because free list buffer header used to be inlined with buffer data. In addition to prevent the performance regression for small transactions, this patch improves the performance for transactions that take up more than one page. Modify alloc selftest to work with the shrinker change. Test: Run memory intensive applications (Chrome and Camera) to trigger shrinker callbacks. Binder frees memory as expected. Test: Run binderThroughputTest with high memory pressure option enabled. Signed-off-by:

Binder driver allocates buffer meta data in a region that is mapped in user space. These meta data contain pointers in the kernel. This patch allocates buffer meta data on the kernel heap that is not mapped in user space, and uses a pointer to refer to the data mapped. Signed-off-by:

binder_alloc_selftest tests that alloc_new_buf handles page allocation and deallocation properly when allocate and free buffers. The test allocates 5 buffers of various sizes to cover all possible page alignment cases, and frees the buffers using a list of exhaustive freeing order. Test: boot the device with ANDROID_BINDER_IPC_SELFTEST config option enabled. Allocator selftest passes. Signed-off-by:

This gave us more freedom to change/add/remove operations without recompiling all device driver. Typically, Carrier board implement the fmc operations, so they will not use these helpers. Signed-off-by:

There is a mistake here where we accidentally use sizeof(TB_CFG_PKG_RESET) instead of just TB_CFG_PKG_RESET. The size of an int is 4 so it's the same as TB_CFG_PKG_NOTIFY_ACK. Fixes: d7f781bf ("thunderbolt: Rework control channel to be more reliable") Reported-by:

If secure authentication of a devices fails, either because the device already has another key uploaded, or there is some other error sending challenge to the device, and the user only wants to approve the device just once (without a new key being uploaded to the device) the current implementation does not allow this because the key cannot be cleared once set even if we allow it to be changed. Make this scenario possible and allow clearing the key by writing empty string to the key sysfs file. Signed-off-by:
