* treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook2018-06-136-17/+22

This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C than Sunrisepoint which uses 120 MHz. Preliminary information was that both share the same clock rate but actual silicon implements elevated rate for better support for 3.4 MHz high-speed I2C. This incorrect input clock rate results too high I2C bus clock in case ACPI doesn't provide tuned I2C timing parameters since I2C host controller driver calculates them from input clock rate. Fix this by using the correct rate. We still share the same 230 ns SDA hold time value than Sunrisepoint.

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.

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.
