[PATCH v2 0/5] Enable miscellaneous hardware blocks to boot WPSS

[Sibi Sankar]

This series enables miscellaneous hardware blocks to boot Wireless
Processor Subsystem (WPSS) on SC7280 SoC.

V2:
 * place resets and num_resets adjacent to each other [Stephen]
 * drop incorrect useage of tcsr_mutex_regs [Bjorn]
 * Qualcomm is expected to drop master/slave naming from its mproc nodes
   in future SoCs.

Sibi Sankar (5):
  dt-bindings: mailbox: Add WPSS client index to IPCC
  dt-bindings: reset: aoss: Add AOSS reset controller binding
  dt-bindings: reset: pdc: Add PDC Global bindings
  reset: qcom: Add PDC Global reset signals for WPSS
  arm64: dts: qcom: sc7280: Add nodes to boot WPSS

Why not go one step further:

	u32 mask = BIT(data->desc->resets[idx].bit);

	return regmap_update_bits(data->regmap, data->desc->offset, mask, mask);

That seems to be a common pattern in other qcom drivers.
Either way, with the above reset/num_reset changes:

Hey Philipp,

Thanks for the review. Will get them
fixed in the next re-spin.

Philipp, please do take patch 2-4 through your tree, that way we avoid

update MAINTAINERS to ensure that you will receive future patches in
