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
