Pull char/misc driver updates from Greg KH: "Here is the big set of char and misc driver patches for 4.21-rc1. Lots of different types of driver things in here, as this tree seems to be the "collection of various driver subsystems not big enough to have their own git tree" lately. Anyway, some highlights of the changes in here: - binderfs: is it a rule that all driver subsystems will eventually grow to have their own filesystem? Binder now has one to handle the use of it in containerized systems. This was discussed at the Plumbers conference a few months ago and knocked into mergable shape very fast by Christian Brauner. Who also has signed up to be another binder maintainer, showing a distinct lack of good judgement :) - binder updates and fixes - mei driver updates - fpga driver updates and additions - thunderbolt driver updates - soundwire driver updates - extcon driver updates - nvmem driver updates - hyper-v driver updates - coresight driver updates - pvpanic driver additions and reworking for more device support - lp driver updates. Yes really, it's _finally_ moved to the proper parallal port driver model, something I never thought I would see happen. Good stuff. - other tiny driver updates and fixes. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (116 commits) MAINTAINERS: add another Android binder maintainer intel_th: msu: Fix an off-by-one in attribute store stm class: Add a reference to the SyS-T document stm class: Fix a module refcount leak in policy creation error path char: lp: use new parport device model char: lp: properly count the lp devices char: lp: use first unused lp number while registering char: lp: detach the device when parallel port is removed char: lp: introduce list to save port number bus: qcom: remove duplicated include from qcom-ebi2.c VMCI: Use memdup_user() rather than duplicating its implementation char/rtc: Use of_node_name_eq for node name comparisons misc: mic: fix a DMA pool free failure ptp: fix an IS_ERR() vs NULL check genwqe: Fix size check binder: implement binderfs binder: fix use-after-free due to ksys_close() during fdget() bus: fsl-mc: remove duplicated include files bus: fsl-mc: explicitly define the fsl_mc_command endianness misc: ti-st: make array read_ver_cmd static, shrinks object size ...

mtd: spi-nor: parse SFDP 4-byte Address Instruction Table

2018-12-10T20:59:08+00:00

Add support for SFDP (JESD216B) 4-byte Address Instruction Table. This table is optional but when available, we parse it to get the 4-byte address op codes supported by the memory. Using these op codes is stateless as opposed to entering the 4-byte address mode or setting the Base Address Register (BAR). Flashes that have the 4BAIT table declared can now support SPINOR_OP_PP_1_1_4_4B and SPINOR_OP_PP_1_4_4_4B opcodes. Tested on MX25L25673G. Signed-off-by: Cyrille Pitchen [tudor.ambarus@microchip.com: - rework erase and page program logic, - pass DMA-able buffer to spi_nor_read_sfdp(), - introduce SPI_NOR_HAS_4BAIT - various minor updates.] Signed-off-by: Tudor Ambarus Signed-off-by: Boris Brezillon

mtd: spi-nor: Add an SPDX tag to spi-nor.{c,h}

2018-12-10T20:59:08+00:00

Add SPDX tags to replace the license boiler-plate and fix the MODULE_LICENSE() definition in spi-nor.c to match the license text (GPL v2). Interestingly, spi-nor.h and spi-nor.c do not use the same license (GPL v2+ for spi-nor.h, GPL v2 for spi-nor.c). Signed-off-by: Boris Brezillon Reviewed-by: Tudor Ambarus

mtd: spi-nor: Add the SNOR_F_4B_OPCODES flag

2018-12-10T20:59:07+00:00

Some flash_info entries have the SPI_NOR_4B_OPCODES flag set to let the core know that the flash supports 4B opcode. While this solution works fine for id-based caps detection, it doesn't work that well when relying on SFDP-based caps detection. Let's add an SNOR_F_4B_OPCODES flag so that the SFDP parsing code can set it when appropriate. Signed-off-by: Boris Brezillon Reviewed-by: Tudor Ambarus

mtd: spi-nor: add macros related to MICRON flash

mtd: rawnand: Deprecate the dummy_controller field

2018-12-07T09:58:11+00:00

We try to force NAND controller drivers to properly separate the NAND controller object from the NAND chip one, so let's deprecate the dummy controller object embedded in nand_chip to encourage them to create their own instance. Signed-off-by: Boris Brezillon Signed-off-by: Miquel Raynal

mtd: rawnand: Move ->setup_data_interface() to nand_controller_ops

2018-12-07T09:38:27+00:00

->setup_data_interface() is a controller specific method and should thus be placed in nand_controller_ops. In order to make that work with controllers that support keeping pre-configured timings we need to add a new NAND_KEEP_TIMINGS flag to inform the core it should skip the timings selection step.
