net: ipa: support IPA interrupt addresses for IPA v4.7

2021-03-26T00:22:30Z

Starting with IPA v4.7, registers related to IPA interrupts are located at a fixed offset 0x1000 above than the addresses used for earlier versions. Define and use functions to provide the offset to use for these registers based on IPA version. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: fix two inconsistent IPA register names

2020-11-18T23:53:48Z

Rename two suspend IRQ registers so they follow the IPA_REG_IRQ_xxx naming convention used elsewhere. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: enable wakeup on IPA interrupt

2020-09-19T00:47:07Z

Now that we handle wakeup interrupts properly, arrange for the IPA interrupt to be treated as a wakeup interrupt. Signed-off-by: Alex Elder Reviewed-by: Bjorn Andersson Signed-off-by: David S. Miller

soc: qcom: ipa: clocking, interrupts, and memory

2020-03-09T05:07:09Z

This patch incorporates three source files (and their headers). They're grouped into one patch mainly for the purpose of making the number and size of patches in this series somewhat reasonable. - "ipa_clock.c" and "ipa_clock.h" implement clocking for the IPA device. The IPA has a single core clock managed by the common clock framework. In addition, the IPA has three buses whose bandwidth is managed by the Linux interconnect framework. At this time the core clock and all three buses are either on or off; we don't yet do any more fine-grained management than that. The core clock and interconnects are enabled and disabled as a unit, using a unified clock-like abstraction, ipa_clock_get()/ipa_clock_put(). - "ipa_interrupt.c" and "ipa_interrupt.h" implement IPA interrupts. There are two hardware IRQs used by the IPA driver (the other is the GSI interrupt, described in a separate patch). Several types of interrupt are handled by the IPA IRQ handler; these are not part of data/fast path. - The IPA has a region of local memory that is accessible by the AP (and modem). Within that region are areas with certain defined purposes. "ipa_mem.c" and "ipa_mem.h" define those regions, and implement their initialization. Signed-off-by: Alex Elder Signed-off-by: David S.
