2018-12-12iio: adc: qcom-spmi-adc5: Initialize prescale properlyEvan Green
adc5_get_dt_data uses a local, prop, feeds it to adc5_get_dt_channel_data, and then puts the result into adc->chan_props. The problem is adc5_get_dt_channel_data may not initialize that structure fully, so a garbage value is used for prescale if the optional "qcom,pre-scaling" is not defined in DT. adc5_read_raw then uses this as an array index, generating a crash that looks like this: [ 6.683186] Unable to handle kernel paging request at virtual address ffffff90e78c7964 Call trace: qcom_vadc_scale_code_voltage_factor+0x74/0x104 qcom_vadc_scale_hw_calib_die_temp+0x20/0x60 qcom_adc5_hw_scale+0x78/0xa4 adc5_read_raw+0x3d0/0x65c iio_channel_read+0x240/0x30c iio_read_channel_processed+0x10c/0x150 qpnp_tm_get_temp+0xc0/0x40c of_thermal_get_temp+0x7c/0x98 thermal_zone_get_temp+0xac/0xd8 thermal_zone_device_update+0xc0/0x38c qpnp_tm_probe+0x624/0x81c platform_drv_probe+0xe4/0x11c really_probe+0x188/0x3fc driver_probe_device+0xb8/0x188 __device_attach_driver+0x114/0x180 bus_for_each_drv+0xd8/0x118 __device_attach+0x180/0x27c device_initial_probe+0x20/0x2c bus_probe_device+0x78/0x124 deferred_probe_work_func+0xfc/0x138 process_one_work+0x3d8/0x8b0 process_scheduled_works+0x48/0x6c worker_thread+0x488/0x7cc kthread+0x24c/0x264 ret_from_fork+0x10/0x18 Unfortunately, when I went to add the initializer for this and tried to boot it, my machine shut down immediately, complaining that it was hotter than the sun. It appears that adc5_chans_pmic and adc5_chans_rev2 were initializing prescale_index as if it were directly a divisor, rather than the index into adc5_prescale_ratios that it is. Fix the uninitialized value, and change the static initialization to use indices into adc5_prescale_ratios.

2018-12-12staging: vchiq: rework remove_event handlingArnd Bergmann
I had started the removal of semaphores in this driver without knowing that Nicolas Saenz Julienne also worked on this. In case of the "remote event" infrastructure, my solution seemed significantly better, so I'm proposing this as a change on top. The problem with using either semaphores or completions here is that it's an overly complex way of waking up a thread, and it looks like the 'count' of the semaphore can easily get out of sync, even though I found it hard to come up with a specific example. Changing it to a 'wait_queue_head_t' instead of a completion simplifies this by letting us wait directly on the 'event->fired' variable that is set by the videocore. Another simplification is passing the wait queue directly into the helper functions instead of going through the fragile logic of recording the offset inside of a structure as part of a shared memory variable. This also avoids one uncached memory read and should be faster. Note that I'm changing it back to 'killable' after the previous patch changed 'killable' to 'interruptible', apparently based on a misunderstanding of the subtle down_interruptible() macro override in vchiq_killable.h.

2018-12-12staging: comedi: change do_insn*_ioctl to allow more samplesSpencer E. Olson
Changes do_insn*_ioctl functions to allow for data lengths for each comedi_insn of up to 2^16. This patch also changes these functions to only allocate as much memory as is necessary for each comedi_insn, rather than allocating a fixed-sized scratch space. In testing some user-space code for the new INSN_DEVICE_CONFIG_GET_ROUTES facility with some newer hardware, I discovered that do_insn_ioctl and do_insnlist_ioctl limited the amount of data that can be passed into the kernel for insn's to a length of 256. For some newer hardware, the number of routes can be greater than 1000. Working around the old limits (256) would complicate the user-space/kernel interaction. The new upper limit is reasonable with current memory available and does not otherwise impact the memory footprint for any current or otherwise typical configuration. Signed-off-by: Spencer E.

2018-12-12staging: mt7621-spi: drop support for SPI mode 1/2/3Chuanhong Guo
As explained in previous patch, this SPI controller seems to be tested on SPI flash only before mass production and some bits are swizzled under other SPI modes probably due to incorrect wiring inside the silicon. Drop implementation of SPI mode 1/2/3 since they are broken. Also drop RT2880_SPI_MODE_BITS macro because we now have only SPI_LSB_FIRST implemented and the mode_bits is so short that we don't need a macro there.

2018-12-12staging: mt7621-spi: drop the broken full-duplex modeChuanhong Guo
According to John Crispin (aka blogic) on IRC on Nov 26 2018: so basically i made cs1 work for MTK/labs when i built the linkit smart for them. the req-sheet said that cs1 should be proper duplex spi. however .... 1) the core will always send 1 byte before any transfer, this is the m25p80 command. 2) mode 3 is broken and bit reversed (?) 3) some bit are incorrectly wired in hw for mode2/3 we wrote a test script and test for [0-0xffff] on all modes and certain bits are swizzled under certain conditions and it was not possible to fix this even using a hack. we then decided to use spi-gpio and i never removed the errornous code basically the spi is fecked for anything but half duplex spi mode0 running a sflash on it The controller will always send some data from OPCODE register under half duplex mode before starting a full-duplex transfer, so the full-duplex mode is broken. This piece of code also make CS1 unavailable since it forces the broken full-duplex mode to be used on CS1.
