According to documentation the function has 2 bits for reset while iDMA 64-bit has only one. Rename it accordingly. Note, there is no functional change since we always handle them together. Signed-off-by:

According to documentation REMAP register has to be programmed in either DMA or PIO mode of the slice. Move the DMA capability check below to let REMAP register be programmed in PIO mode.

The cros_ec_i2c driver is still active after it had suspended or before it resumes. Besides that, it also tried to transfer data even after the I2C host had been suspended. This will lead the system to crash. During the test, we also observe that the EC needs to be resumed earlier due to some status polling from the EC FW (e.g. battery status). So we move the PM ops to late stage to make it work normally. Signed-off-by:

Reboot or shutdown during delayed works could corrupt communication with EC and certain I2C controller may not be able to recover from the error state. This patch registers a shutdown callback used to cancel the debugfs log worker thread. Signed-off-by:

We should stop our worker thread while we're suspended. If we don't then we'll get messages like: cros-ec-spi spi5.0: spi transfer failed: -108 cros-ec-spi spi5.0: cs-deassert spi transfer failed: -108 cros-ec-ctl cros-ec-ctl.0.auto: EC communication failed Signed-off-by:

If we cannot communicate with the EC chip to detect the protocol version and its features, it's very likely useless to continue. Else we will commit all kind of uninformed mistakes (using the wrong protocol, the wrong buffer size, mixing the EC with other chips). Signed-off-by:

The COMP1 and COMP2 elements are in 0 and 1 respectively so this code is accessing the wrong elements and one space beyond the end of the array. The "id" variable is never COMP (0) so that code can be removed. Fixes: 6851ad3a ("TPS65911: Comparator: Add comparator driver") Reported-by:

As part of the effort to remove VLAs from the kernel[1], this creates constants for the checksum lengths of CCITT and 8B2C and changes crc_calculated to be the maximum size of a checksum. https://lkml.org/lkml/2018/3/7/621Signed-off-by:

When AXP806 support was added, POK was incorrectly expanded to PWROK. However, the datasheet lists them as POK[LSNP], which is the same as on the AXP288. Furthermore, the registers associated with POK functions are the same as the PEK on the other AXP PMICs. This suggests that "POK" means "Power On Key", much like "PEK" means "Power Enable Key", instead of "Power OK". This patch changes the "PWROK" prefix to "POK" for these interrupts. Signed-off-by:

Now GPIOD has support for both pdata systems and for non-standard DT bindings the Arizona reset GPIO can be converted to use it. Worth noting gpiod_set_raw_value_cansleep is used to match the behaviour of the old GPIOs. This is because the part is fairly widely used and it is unknown how many DTs are correctly setting active low through device tree, so to avoid breaking any existing users it is best to match the previous behaviour.
