Currently, ipq807x only covers Qualcomm IPQ807x SoC-s. However, Qualcomm also has IPQ60xx and IPQ50xx SoC-s under the AX WiSoC-s and they share a lot of stuff with IPQ807x, especially IPQ60xx so to avoid duplicating kernel patches and everything lets make a common target with per SoC subtargets. Start doing that by renaming ipq807x to qualcommax so that dependencies on ipq807x target can be updated. Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] thermal/drivers/tsens: Add support for combined interrupt
|
|
|
|
Despite using tsens v2.3 IP, IPQ8074 and IPQ6018 only have one IRQ for
|
|
signaling both up/low and critical trips.
