2020-01-21Input: axp20x-pek - respect userspace wakeup configurationSamuel Holland
Unlike most other power button drivers, this driver unconditionally enables its wakeup IRQ. It should be using device_may_wakeup() to respect the userspace configuration of wakeup sources. Because the AXP20x MFD device uses regmap-irq, the AXP20x PEK IRQs are nested off of regmap-irq's threaded interrupt handler. The device core ignores such interrupts, so to actually disable wakeup, we must explicitly disable all non-wakeup interrupts during suspend.

2020-01-21mtd: rawnand: denali: remove hard-coded DENALI_DEFAULT_OOB_SKIP_BYTESMasahiro Yamada
As commit 0d55c668b218 (mtd: rawnand: denali: set SPARE_AREA_SKIP_BYTES register to 8 if unset") says, there were three solutions discussed: [1] Add a DT property to specify the skipped bytes in OOB [2] Associate the preferred value with compatible [3] Hard-code the default value in the driver At that time, [3] was chosen because I did not have enough information about the other platforms than UniPhier. That commit also says "The preferred value may vary by platform. If so, please trade up to a different solution." My intention was to replace [3] with [2], not keep both [2] and [3]. Now that we have switched to [2] for SOCFPGA's SPARE_AREA_SKIP_BYTES=2, [3] should be removed. This should be OK because denali_pci.c just gets back to the original behavior.

2020-01-21mtd: rawnand: denali_dt: add reset controllingMasahiro Yamada
According to the Denali NAND Flash Memory Controller User's Guide, this IP has two reset signals. rst_n: reset most of FFs in the controller core reg_rst_n: reset all FFs in the register interface, and in the initialization sequencer This commit supports controlling those reset signals. It is possible to control them separately from the IP point of view although they might be often tied up together in actual SoC integration. The IP spec says, asserting only the reg_rst_n without asserting rst_n will cause unpredictable behavior in the controller. So, the driver deasserts ->rst_reg and ->rst in this order. Another thing that should be kept in mind is the automated initialization sequence (a.k.a. 'bootstrap' process) is kicked off when reg_rst_n is deasserted. When the reset is deasserted, the controller issues a RESET command to the chip select 0, and attempts to read out the chip ID, and further more, ONFI parameters if it is an ONFI-compliant device. Then, the controller sets up the relevant registers based on the detected device parameters. This process might be useful for tiny boot firmware, but is redundant for Linux Kernel because nand_scan_ident() probes devices and sets up parameters accordingly. Rather, this hardware feature is annoying because it ends up with misdetection due to bugs. So, commit 0615e7ad5d52 ("mtd: nand: denali: remove Toshiba and Hynix specific fixup code") changed the driver to not rely on it. However, there is no way to prevent it from running. The IP provides the 'bootstrap_inhibit_init' port to suppress this sequence, but it is usually out of software control, and dependent on SoC implementation. As for the Socionext UniPhier platform, LD4 always enables it. For the later SoCs, the bootstrap sequence runs depending on the boot mode. I added usleep_range() to make the driver wait until the sequence finishes. Otherwise, the driver would fail to detect the chip due to the race between the driver and hardware-controlled sequence.

2020-01-21mtd: rawnand: denali_dt: Add support for configuring SPARE_AREA_SKIP_BYTESMarek Vasut
The SPARE_AREA_SKIP_BYTES register is reset when the controller reset signal is toggled. Yet, this register must be configured to match the content of the NAND OOB area. The current default value is always set to 8 and is programmed into the hardware in case the hardware was not programmed before (e.g. in a bootloader) with a different value. This however does not work when the block is reset properly by Linux. On Altera SoCFPGA CycloneV, ArriaV and Arria10, which are the SoCFPGA platforms which support booting from NAND, the SPARE_AREA_SKIP_BYTES value must be set to 2. On Socionext Uniphier, the value is 8. This patch adds support for preconfiguring the default value and handles the special SoCFPGA case by setting the default to 2 on all SoCFPGA platforms, while retaining the original behavior and default value of 8 on all the other platforms.

A read from a Winbond W25Q32FV SPI NOR memory chip on my MMP2 returns wrong data. It seems like SSE doesn't do the right thing on MMP2 at all. After enabling the SPI port back again, the FIFO reads return garbage. Things can be brought back to order by telling the PMU to reset the block. Here's a good transaction with said chip: # busybox devmem 0xd4035000 32 0x00001987 # SSCR0 # echo 0 >/sys/class/gpio/gpio46/value # (assert CS) # busybox devmem 0xd4035010 32 0x0000009f # SSDR (read ID command) # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 # SSDR 0x000000ff # busybox devmem 0xd4035010 # SSDR 0x000000ef # Correct response # busybox devmem 0xd4035010 # SSDR 0x00000040 # busybox devmem 0xd4035010 # SSDR 0x00000016 # busybox devmem 0xd4035010 # SSDR 0x00000000 # busybox devmem 0xd4035010 # SSDR 0x00000000 # busybox devmem 0xd4035010 # SSDR 0x00000000 # echo 1 >/sys/class/gpio/gpio46/value # (deassert CS) # Flipping off an on SSE, then running another transaction: # busybox devmem 0xd4035000 32 0x00001907 # SSCR0, SSE off # busybox devmem 0xd4035000 32 0x00001987 # SSCR0, SSE on # echo 0 >/sys/class/gpio/gpio46/value # (assert CS) # busybox devmem 0xd4035010 32 0x0000009f # SSDR (read ID command) # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 32 0x00000000 # SSDR # busybox devmem 0xd4035010 # SSDR 0x000000ff # busybox devmem 0xd4035010 # SSDR 0x000000ff # Garbage! # busybox devmem 0xd4035010 # SSDR 0x000000ff # Oh no # busybox devmem 0xd4035010 # SSDR 0x000000ff # busybox devmem 0xd4035010 # SSDR 0x000000ff # busybox devmem 0xd4035010 # SSDR 0x000000ff # busybox devmem 0xd4035010 # SSDR 0x000000ff # echo 1 >/sys/class/gpio/gpio46/value # (deassert CS) # Sometimes the response is not just ones, but something that looks like bits of a response from a previous transaction. I can't see a fix other than not touching the SSE altogether after the device is first brought up.

2020-01-21regmap: fix writes to non incrementing registersBen Whitten
When checking if a register block is writable we must ensure that the block does not start with or contain a non incrementing register.

2020-01-21spi: spi-fsl-qspi: Ensure width is respected in spi-mem operationsMichael Walle
Make use of a core helper to ensure the desired width is respected when calling spi-mem operators. Otherwise only the SPI controller will be matched with the flash chip, which might lead to wrong widths. Also consider the width specified by the user in the device tree.
