Subject: [PATCH net-next v7 0/2] Add support for ICSSG PA_STATS

Hi,

This series adds support for PA_STATS. Previously this series was a
standalone patch adding documentation for PA_STATS in dt-bindings file
ti,pruss.yaml.

As discussed in v4, posting driver and binding patch together.

Changes isnce v6:
*) Addressed Roger's comments and renamed stats related data strcutures
and array so that they remain consitent.
*) Re-ordered data structures and arrays related to stats type as asked
by Roger.
*) Modified commit message to state these additional changes

Changes since v5:
*) Used ARRAY_SIZE(icssg_all_pa_stats) instead of ICSSG_NUM_PA_STATS so
   that it's consistent with the loop as suggested by Dan Carpenter
   <dan.carpenter@...aro.org>
*) Created emac->pa_stats array for storing pa_stats as suggested by
   Dan Carpenter <dan.carpenter@...aro.org>
*) Renamed `icssg_all_stats` to `icssg_mii_g_rt_stats`.
*) Added entry for pa_stats in kernel doc for structure prueth as asked by
   Simon Horman <horms@...nel.org>.
*) Improved syntax for kernel doc of pa_stats_regs register by dropping
   u32 from kernel doc.

Changes since v4:
*) Added net-next to both driver and binding patch as they are both now
   meant to be merged via net-next.
*) Added Acked by tag of Nishanth Menon <nm@...com>
*) Dropped device tree patches as they don't need merge now.
*) Modified patch 2 to use ethtool_puts() as suggested by Jakub Kicinski
   <kuba@...nel.org>

Changes since v3:
*) Added full series as asked by Nishanth Menon <nm@...com>

Changes from v2 to v3:
*) Added RB tag of Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org> to
   patch 2/2
*) Added patch 1/2 to the series as the binding file is orphan.

Changes from v1 to v2:
*) Added ^ in pa-stats as suggested by Krzysztof Kozlowski
   <krzk@...nel.org>
*) Moved additionalProperties: false to right after type:object as
   suggested by Krzysztof Kozlowski <krzk@...nel.org>
*) Updated description of pa-stats to explain the purpose of PA_STATS
   module in context of ICSSG.
