Clean up GPIO PWM driver

pwm: gpio: Add a generic gpio based PWM driver

2018-05-14T08:07:29+00:00

This patch adds a bit-banging gpio PWM driver. It makes use of hrtimers, to allow nano-second resolution, though it obviously strongly depends on the switching speed of the gpio pins, hrtimer and system load. Each pwm node can have 1 or more "pwm-gpio" entries, which will be treated as pwm's as part of a pwm chip. Signed-off-by: Olliver Schinagl

Backport fsi: occ: Use PutOCCSRAM in circular mode for OCC attention

2018-04-30T05:58:56+00:00

We can't do SCOMs from the BMC when the host is booted in secure mode, and without triggering the attention of the OCC our commands won't be processed. Further, the SCOM operation fails, which causes the OCC driver's probe to fail, which leads the BMC to think that the OCC has failed. We have an alternative to the SCOM though: We can trigger the OCC by writing the correct attention magic in circular buffer mode. The PutOCCSRAM operation returns the written data length in the response payload before the 0xCODE word, so the condition testing the success of the operation is rearranged.

Skip OCC scan on driver load

2018-01-22T07:31:19+00:00

HACK to reduce time from IPL start to SBE boot sequence kickoff Figure out a better way to either: 1.) Prevent probe() being called during devicetree scan -or- 2.) Abort probe when OCC is not online, instead of timing out

Ensure FSI device data is available before FSI bus probes are attempted

This fixes error -19 failures on FSI scan

Issue warning instead of abort on nonzero OCC SCOM return code

2018-01-21T08:50:30+00:00

DD2.1 devices on latest hostboot with secure mode enabled return condition flags after SCOM access. OCC access appears to function normally even with these flags set, therefore downgrade the abort to a warning to allow OCC to function.

hwmon: (w83773g) Fix fault detection and reporting

2018-01-17T20:55:08+00:00

Smatch reports: drivers/hwmon/w83773g.c:105 get_fault() warn: shift has higher precedence than mask Code analysis shows that the code is indeed wrong. Fix it, and while we are at it, drop unnecessary typecast.

hwmon: (pmbus/ir35221) Remove unnecessary scaling

2018-01-16T17:54:30+00:00

The ir35221 datasheet describes specific scaling factors for a number of commands which the current driver applies when reading. However now that the ir35221 has been tested on machines with more easily verifiable readings these descriptions have turned out to be superfluous and reading each command according to the linear format is sufficient.

hwmon (occ): Fix integer overflow in multiplication

2018-01-16T17:54:30+00:00

Power values were overflowing INT_MAX when being converted to microwatts, even though the storage was sufficiently large (unsigned 64 bit). Change literals to unsigned long long. Also change tmep storage to u32 to avoid overflows at 65000 millidegrees. OpenBMC-Staging-Count: 1 Signed-off-by: Edward A. James Signed-off-by: Joel Stanley
